    Abstract [en]

    In the recent decades the recognition of maintenance as an effective part of the company competitiveness has grown. In order to enhance maintenance performance and its positive impact, integration with the rest of the plant activities should be planned and performed. In this study, Maintenance Function Deployment model was applied on a real data of a case company. The model was used to analyse the company’s production with respect to the business and economic variables. This was done first through finding loss causes of the strategic goals of the case company, then breaking down these causes and their costs into their root causes. Based on economic estimations, the results show that the major root causes behind losses are insufficient training of personnel and lack of maintenance integration. It is concluded that properly considering the integration of maintenance within the company’s activities, reduces loss and improves the company’s performance. Also, that applying MFD eases the identification of the root-causes behind losses as well as quantifying and prioritizing the economic losses. © Springer Nature Switzerland AG 2019.

    Maintenance in Real Estate and Manufacturing Industries: Differences, Problems, Needs and Potentials - Four Case Studies2016In: Proceedings of the 10th World Congress on Engineering Asset Management (WCEAM 2015) / [ed] Koskinen, KT; Kortelainen, H; Aaltonen, J; Uusitalo, T; Komonen, K; Mathew, J; Laitinen, J, Switzerland: Springer, 2016, p. 13-27Conference paper (Refereed)
    Abstract [en]

    It is about 50 % of the activities in the housing sector in the EU region are related to maintenance. According to several publications, building management systems are still quite rare and efficient methodologies for service life prediction of building parts still need to be developed. Also, recent studies show difficulties in finding comprehensive answers concerning, e.g. identifying risks and preventive maintenance actions. Incomplete information can easily lead to incorrect maintenance actions. The problem addressed is: How to improve performance and cost-effectiveness of the maintenance applied on real estate facilities especially buildings to reduce maintenance and management costs and increase company profit? The study’s objectives are to analyse maintenance; techniques, costs, weaknesses and potentials, and compare it with manufacturing industry experience. Also, to investigate whether there is a need for a DSS for planning and follow up cost-effective CBM. The major results of four case studies are; (1) Preventive and breakdown maintenance are mainly used and actions are funded from different accounts. (2) The concept of cost-effectiveness is applied occasionally. (3) Lack of CBM-DSS for planning, follow up and evaluate maintenance profitability, and cost-effective improvements of company business and tenant living quality. (4) The profit generated by continuous heating of building thanks efficient maintenance is about 2.332 million SEK. The major conclusion; there is a reasonable opportunity to reduce buildings’ management and maintenance costs.

    Technologies for better utilisation of production process resources2009Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Most companies today are working in a global environment where competition is hard. In order to be able to survive it is essential that the companies utilise their resources as much as possible in order to keep the production cost low. Maintenance plays a crucial role because of its impact on availability, reliability, quality and life cycle cost (LCC). However, being able to use maintenance proactively so as to increase the utilisation of the production process resources requires access to proper tools and methods for deciding on what maintenance to use and to follow up maintenance impact.

    Consequently, the overall research problem discussed in the thesis is: How to select a maintenance policy and follow up its performance with respect to cost-effectiveness in order to improve company profitability. In order to solve this overall research problem it has been broken down into four research questions R1: How can different approaches intended for maintaining or improving production process performance assist in the identification, analysis, elimination and prevention of recurrence of problems in a production process?, R2: How should maintenance be selected on the basis of cost-effectiveness?, R3: How should the technical and financial performance of maintenance be measured in order to enable cost-effective improvements? and R4: How to access relevant data required for cost-effective decisions in maintenance?.

    The philosophical basis applied in the work presented in this thesis is systems theory. When looking at maintenance, it is necessary to have a wide perspective and also see the interaction between maintenance and other relevant working areas.

    The major contributions that have been achieved and reported in the thesis are: 1. A literature review regarding current approach abilities to identify, analyse and prevent the recurrence of problems, 2. The development of a conceptual model for measuring the maintenance impact through a set of key performance indicators indicating where and how much to invest in maintenance., 3. The development of a maintenance support system for measuring the economic/financial impact of maintenance on both operative and strategic levels, 4. The development of a model for selecting and improving maintenance policies based on cost-effectiveness. The model presented is characterised by being flexible, in the meaning that it is possible to make a selection among any types of maintenance policies., 5. The definition and description of a common database containing relevant data for maintenance management and 6. Results from an exploratory study regarding IT maturity within maintenance management in Swedish industry are presented.

    The main conclusion of the thesis is that the tools and methods described in this thesis can represent important elements in a system to continuously and cost-effectively improve maintenance performance and thereby better utilise the resources in the production process.

    EcoCon: A System for Monitoring Economicand Technical Performance of Maintenance2018In: Engineering Asset Management 2016: Proceedings of the 11th World Congress on Engineering Asset Management, Switzerland: Springer, 2018, p. 85-97Conference paper (Refereed)
    Abstract [en]

    Maintenance has been treated as a cost-center although it has obviousdirect impact on company production, delivery on time, product quality andconsequently company business. In this paper we develop and test a new system(EcoCon) for monitoring and assessing the economic impact of maintenance on aproduction process. EcoCon is tested using real industrial data collected over3 years. The main findings are that by using EcoCon it is possible to assessmaintenance economic impact on a production process. Also, EcoCon providesdata for analyzing causes behind deviations in maintenance and production performance.It can be applied on companies of similar production process/machine. But,in some cases, the system demands marginal accommodation to suit the differencesin the maintenance economic related factors among companies. EcoCon providesproduction and maintenance mangers reliable overview of maintenance importancethrough monitoring maintenance economic impact by linking technical productionperformance, e.g. downtime, to economic savings/losses generated due to maintenanceperformance and other activities.

    Selecting and improving a maintenance policy for mechanical components using cost-effectiveness2012In: International Journal of Strategic Engineering Asset Management (IJSEAM), ISSN 1759-9733, E-ISSN 1759-9741, Vol. 1, no 2, p. 153-171Article in journal (Refereed)
    Abstract [en]

    Maintenance has in recent years more and more become recognised as contributing to company profitability and competitiveness. Consequently, the need of selecting the most cost-effective maintenance for a certain component/equipment under certain circumstances has become more emphasised. For a certain component/equipment there might be more than one technically suitable maintenance policy to choose from. The most cost-effective maintenance policy should be selected. In this paper, the most popular selection methods have been introduced, discussed and compared using 11 criteria for identifying their weaknesses and strengths. Also, a study exploring maintenance selection methods in Swedish industry is conducted. Furthermore, a model for selecting and improving a maintenance policy based on cost-effectiveness is developed, tested and discussed in an application example. The model is designed to be user-friendly and usable for all types of maintenance policies. It can utilise historical data regarding failures if available and allow feedback and continuous improvements.

    System for monitoring machines financial and technical effectiveness2006In: Condition monitoring and diagnostic engineering management; COMADEM 2006 / [ed] Kumar, U ; Parida A. ; Rao R. B. K. N., 2006, p. 219-230Conference paper (Refereed)
    Abstract [en]

    The positive effects of maintenance on product quality, machine, ability to deliver the expected production on time and on production costs are well accepted in the scientific community. Never the less, a survey made in Swedish industry indicates that the positive contribution of maintenance is in general still not recognised or fully understood. Maintenance is still to a great extent seen as an unnecessary cost. To make it possible to recognise the impact of maintenance on the production process, a simple to use and reliable system for assessing its impact is required. This system should assist in distinguishing effects from actions taken in different working areas such as maintenance and logistics to enhance process performance. In this article a simple and transparent system for monitoring the performance of a production process in financial terms with respect to maintenance effect is presented. This system is based on a model describing how performance of the production can be related to vibration-based maintenance. The main result presented in this paper is a simple, transparent and user-friendly system for monitoring and assessing the performance of the production process with respect to maintenance. The main conclusion is that using this system makes the hard task of monitoring maintenance impact on the production process easier and faster and thereby also easier follow up the cost-effectiveness of investment in maintenance.

    Managers’ Attitudes towards IT Support: a Study on How Maintenance Management IT Support is Apprehended in Swedish Industry2011In: 24th international congress on Condition Monitoring and Diagnostics Engineering Management: Advances in Industrial Asset Integrity Management / [ed] Maneesh Singh, Raj B. K. N. Rao and J. P. Liyanage, Kolhata, India: Publishing Services PL , 2011, p. 1597-1607Conference paper (Refereed)
    Abstract [en]

    Decision making for asset management requires sophisticated tools which support daily planning as well as strategic development and improvement. What are the apprehended benefits with the current IT support for maintenance management and which problems do the maintenance managers struggle with? Are the managers satisfied with their IT solutions? What would they like to change in the future and what are the obstacles? Questions highly important as input for further technical enhancement of IT support for maintenance management, as well as they can help us in finding non-technical solutions to the problems encountered. This paper reports on maintenance and asset managers’ attitudes towards their IT support. The findings are based on two interview studies conducted in Sweden by the authors during 2008-2009. Findings reveal that the respondents are overall satisfied with their IT systems and they got appropriate support for their apprehended needs. Although, the managers report several problems faced, for instance with the integration towards other enterprise systems resulting in poor fit of functionality to the maintenance requirements. There are also problems in accessing relevant data for follow up of maintenance activities and the IT support could in general be better suited for decision making.

    Partners in maintenance: possibilities in using partnering-based maintenance contracts for Swedish railway2019In: Asset Intelligence through Integration and Interoperability and Contemporary Vibration Engineering Technologies: Proceedings of the 12th World Congress on Engineering Asset Management and the 13th International Conference on Vibration Engineering and Technology of Machinery / [ed] Joseph Mathew C W Lim Lin Ma Don Sands Michael E. Cholette Pietro Borghesani, Springer, 2019, p. 267-276Chapter in book (Refereed)
    Abstract [en]

    Traditionally, procurement of maintenance has been based on fixed price on defined work. These types of contract forms can lead to negotiations on everything not included in the price, which may result in delays and a sense of distrust when all parties primarily look after themselves. Recently, forms for cooperation based on mutual trust and fairness for all parties have been developed; partnering. Partnering is characterized by common objectives and project organization, and risk analysis. The project is created and operated in cooperation with customers, contractors, suppliers and consultants. Transparency is a cornerstone of partnering and openness is what mainly differentiates partnering from traditional contractor projects. The Swedish railway uses traditional and very detailed contracting principles. This leads to several problems, such as lack of information and knowledge transfer between parties and life cycle phases, and no incentives for quality and productivity improvements. Is applying the concept of partnering for railway maintenance a solution to these problems? If so, why is the concept not already commonly applied and what are the barriers? This paper introduces the concept of partnering and reviews current research within the area. Thereafter, the possibilities in using partnering-based maintenance in Swedish railway are discussed.

    Service management models for railway infrastructure, an ecosystem perspective2016In: Proceedings of the 10th World Congress on Engineering Asset Management (WCEAM 2015) / [ed] Koskinen, KT; Kortelainen, H; Aaltonen, J; Uusitalo, T; Komonen, K; Mathew, J; Laitinen, J, Springer, 2016, p. 289-303Conference paper (Refereed)
    Abstract [en]

    Up until 2001 the operation and maintenance of Swedish railway, both the railway infrastructure and the rolling stock, was basically the responsibility of Statens Järnvägar. At this year the operation and maintenance of the Swedish railway was deregulated and as a result the number of actors increased dramatically. Also, during the period from 1990 to 2012 there was an increase in the railway transports of 42% in train-kilometres. This put great demands on the railway infrastructure operations and service, and indications were seen that the infrastructure was deteriorating leading to delivery quality problems. In order to solve the situation several governmental investigations were initiated. In a governmental report the situation of the railway maintenance is described as problematic due to several technical as well as organisational factors, of which the lack of competition is seen as the most important. Despite several investigations, the desired delivery quality is still not reached. This paper focuses on the Swedish railway infrastructure and describes the background and current state of the Swedish railway service management by utilising a business ecosystem perspective, which lets you capture the complexity and dynamics of the surroundings. By applying this perspective, looking outside the traditional framework of suppliers and customers, important areas in need of investigation or development can be singled out.  As a part of the result, the Swedish railway infrastructure industry is modelled as an ecosystem, and directions for future development is pointed out.

    The use of IT within maintenance management for continuous improvement2007In: Proceedings of MIMAR 2007 - 6th IMA International Conference on Modelling in Industrial Maintenance and Reliability, Salford University, 2007, Salford , 2007, p. 51-56Conference paper (Refereed)
    Abstract [en]

    For long maintenance has been treated as a separate working area, isolated from other areas such as production and quality. However, the awareness of maintenance importance and complex nature has increased. To be able to take full advantage of maintenance, systems that assist in the task of planning and follow up on a continuous improvement basis are required. This paper describes the use of maintenance practices and how IT is used for maintenance management by using data from a survey about maintenance management in Swedish industry. The paper finds out that maintenance activities connected to the Plan and Check phases of the PDCA-cycle are emphasised to a low extent while the Do phase is more emphasised and that companies tend to intentionally select CMMS functionality that supports the Plan phase of the PDCA-cycle, if they put high emphasise on these kind of activities.

    A database model supporting a maintenance decision support system for monitoring and assessing the technical and financial condition of a production process2004In: Proceedings of MIMAR 2004 - 5th IMA International Conference on Modelling in industrial maintenance and reliability: Impact on practice, 2004, p. 290-Conference paper (Refereed)
    Abstract [en]

    Maintenance impact on companies' business is well established. It should no longer be considered as a cost-centre; instead it should be treated as a profit-generating centre, since its close relation to companies' internal efficiency. Cost-effective decisions in maintenance require a system for monitoring and assessing the performance of maintenance and its impact on company's profitability. In this article we present a database model, which will be the foundation of a decision support system for monitoring and assessing production process profitability and competitiveness. The database model was developed based on two case studies made at two different companies and later successfully tested.

    Maintenance Practices in Small and Medium Sized Enterprises2013In: Congress Proceedings of COMADEM 2013, International Congress of Condition Monitoring and Diagnostics Engineering Management, Finland: KP media Oy , 2013, p. 669-675Conference paper (Refereed)
    Abstract [en]

    Small and medium sized enterprises (SME) constitute approximately 70% of the gross national product and account for 80% of the global economic growth. SMEs could thus be seen as a driving force of economic growth. Maintenance management plays a critical role in enterprises’ strategic objectives and achieving the competitive advantages desired, and affects the enterprises’ internal effectiveness. To apply an efficient maintenance strategy is therefore of importance for SMEs as well as lager enterprises. As a prerequisite for improvement, one must understand the current situation. But few studies of the maintenance practices in SMEs have been carried out in the past. This paper combines findings from two studies of Swedish industry, one covering SMEs as well as large industries, and one covering only SMEs, in order to depict the current maintenance practices in Swedish SMEs.

     

    Results show that SMEs put most time on execution of maintenance and less on planning and following up and that personnel and spare parts bear the largest costs. The most common trigger of maintenance actions is reported problems, followed by original equipment manufacturer recommendations and sudden failures. Condition monitoring data and statistical analysis are less common triggers though. Quite surprising, the practices in SMEs did not differ that much from the ones in larger enterprises. Sudden failures were less common as trigger for larger companies, and they utilise condition monitoring to a higher extent. Moreover, some more time is allocated for planning in larger companies compared with SMEs. The spare parts cost forms a smaller part in the total budget for larger enterprises. It is concluded that SMEs and large industries have more in common with respect to maintenance practices than they differ.

    A framework for business model development for reaching service management 4.02016In: Journal of Maintenance Engineering, Vol. 1, p. 398-407Article in journal (Refereed)
    Abstract [en]

    The shifting demands on product development and production processes have led to the emergency of new business models, such as integrated product-service offerings. Research shows that the combined business models have a positive effect on the business and as a consequence the importance of aftersales services has increased. But many companies have not yet understood the business opportunities that could be achieved by providing aftersales services. The view of operations and maintenance services has to change; the focus should be on the values created and not in the offers in form of products or services. The approach presented in this paper is an attempt to support this mental shift. A framework for business model development is presented and its applicability in the practical work for reaching new business models is demonstrated by an example. The framework describes business model development in four levels. From maturity point of view, the four steps could be seen as the logical development of the business model from a narrow technical perspective to a holistic product-service perspective. The four levels could be connected to the four industrial revolutions according to the concept of Industry 4.0. Level four is therefore referred to as Service Management 4.0; a business model that supports Industry 4.0 and Maintenance 4.0. In particular, three key concepts reflect the concept of Service Management 4.0: performance-based contracts, partnering and the business ecology concept.

    Analysing IT Functionality Gaps for Maintenance Management2009In: Proceedings of the 4th World Congress of Engineering Asset Management (WCEAM) 2009: Engineering Asset Lifecycle Management / [ed] Dimitris Kiritsis, Christos Emmanouilidis, Andy Koronios, and Joseph Mathew, 2009Conference paper (Refereed)
    Abstract [en]

    Several studies have been carried out for describing the functionality and use of computerised maintenance management systems. A major drawback of these studies is that they do not reveal the actual support for maintenance management. To describe the full situation, the gaps between required support and actual support have to be determined. The gaps are of two kinds: 1) Between the functionality included in the IT system and the functionality required, and 2) Between the functionality included in the IT system and the functionality actually used. To reach a better understanding of the utilisation of IT in maintenance management, the existence of these gaps must be further explored. In this paper, we will study the existence of functionality gaps in maintenance management IT applications using data from a web-based questionnaire survey conducted in Swedish industry. Results show that the IT systems in general provide good support for maintenance management, thus low degree of functionality gaps. However, most commonly unused function was failure cause and consequence analysis and the most commonly unused information was maintenance improvement suggestions. When comparing the results with respect to type of IT system used, some significant differences was revealed, indicating that ERP-systems and production systems do not include all required information for maintenance management. Next step will be to further study the reasons behind the differences in gaps by conducting additional interviews.

    Business Model Development towards Service Management 4.02016In: Product-Service Systems Across Life Cycle / [ed] Cavalieri, S; Ceretti, E; Tolio, T; Pezzotta, G, Elsevier, 2016, Vol. 47, p. 489-494Conference paper (Refereed)
    Abstract [en]

    There is an increasing interest to ensure operational and maintenance (O&M) operations from a strategic perspective, and there are opportunities for both producing companies and service providers to gain benefits. Research shows that the combined business models (products combined with services) have a positive effect on the business. Likewise, it is profitable to think strategically and in long term for enterprises offering maintenance services, especially using performance-based models. But for achieving these benefits the view of the business has to change. The focus should be on the values created and not in the offers in form of products or services. Moreover, the company needs to position itself as an actor not only in the value chain, but in a wider context referred to as the business ecosystem. Making such a shift of focus is hard though, and there is a need to understand both the current state of the business as well as the potential future directions. 

     

    The framework presented in this paper is an attempt to meet these needs. The framework describes business model development in four levels. From maturity point of view, the four steps could be seen as the logical development of the business model from a narrow technical perspective to a holistic product-service perspective. The four levels could also be connected to the industrial development where level four supports Industry 4.0. Level four is referred to as Service Management 4.0. In particular, four key concepts reflect the concept of Service Management 4.0: the mix of products and services in customer offers, performance-based contracts, partnering and the business ecology concept.

    Business Models for After Sales Services — Current State and Future Directions2016In: Proceedings of the 10th World Congress on Engineering Asset Management (WCEAM 2015) / [ed] Koskinen, KT; Kortelainen, H; Aaltonen, J; Uusitalo, T; Komonen, K; Mathew, J; Laitinen, J, Springer, 2016, 1, p. 333-346Conference paper (Refereed)
    Abstract [en]

    The core strategic decisions describing what, where, how and whom to make business with are defined in the business model. The business models adapted by industry have evolved as a consequence of changes in the business environment, the production processes as well as in technology, and the modern, innovative business models focus on long term relationships, performance-based and value-driven customer offers, and knowledge intensive processes. Other aspects are the increased complexity of the offer itself and a holistic perspective on the full value chain. This paper reviews the literature with respect to business models, business strategy and business innovation for postproduction activities, i.e. operations and maintenance (O&M) services. The purpose is to describe the current state within the area and based on this give directions for future research and development. Four main aspects are found as being important for the successful development of O&M service models: the mix of products and services in customer offers (bundling), relevant setup and metrics for performance-based business models and contracts, Information and Communications Technology (ICT) as an enabler and a prerequisite for business model development, and the need for a holistic view on the value chain by utilising the asset management concept.

    COMMON DATABASE APPROACH FOR COST-EFFECTIVE MAINTENANCE MANAGEMENT2006In: Proceedings of ICME2006: International Conference on Maintenance Engineering, 2006, p. 1127-Conference paper (Refereed)
    Abstract [en]

    This paper describes how a common database can play an important role in reaching cost-effective improvements of maintenance performance. The definition and overall design of a common database is presented and illustrated by a case. The main result presented is that it is possible to access a more correct view of the situation in the production by data integration and thereby have a better base for taking decisions in maintenance. The common database supports the development of applications for e.g. monitoring the performance of a production process, for deciding the most cost-effective maintenance policy or for simulating possible maintenance solutions.

    EXPLORING THE INFORMATION TECHNOLOGY MATURITY WITHIN MAINTENANCE MANAGEMENT2008In: COMADEM 2008, Energy and environmental issues: Proceedings of the 21th International Congress and Exhibition Prague, Czech Republic, 11-13 June 2008, Czech Society for Non-destructive Testing, Brno , 2008, p. 243-252Conference paper (Refereed)
    Abstract [en]

    Maintenance is one of several inputs to a production process that contributes to the profitability. To be able to take full advantage of maintenance, systems that assist in the task of planning and follow up is required, which has lead to new demands on information technology (IT) tools supporting the maintenance responsible in reaching the overall strategic objectives of the company. This paper explores how IT is used for maintenance management in Swedish industry from an IT maturity perspective using data from of a cross-sectional study concerning maintenance management practices. The results of this paper support the IT maturity model: Three distinct groups of companies with different levels of IT maturity were found in the study. The analysis also showed that the IT maturity is mainly connected to five of the studied variables: process oriented production, the degree of IT integration, the use of company wide information for diagnosis, maintenance conducted based on statistical modelling, remote diagnosis and maintenance contribution to decreased effects on environment.

    Functionality Gaps in IT Systems for Maintenance Management2012In: International Journal of COMADEM, ISSN 1363-7681, Vol. 15, no 4, p. 38-50Article in journal (Refereed)
    Abstract [en]

    E-maintenance is an information intensive concept highly dependent on relevant and reliable information technology (IT) support. One important prerequisite is that IT functionality fits the demands of the maintenance organisation. The purpose of this paper is to investigate the existence of functionality gaps in the IT applications used for maintenance management. To accomplish the purpose a questionnaire survey asking professional users to estimate the misalignments/gaps in their current IT support. Functionality and information investigated are based on the standard EN 13460 documents for maintenance. The gathered data was thereafter analysed using statistical methods. The study reveals that the used IT solutions in general provide good support for maintenance management. However, the respondents perceive gaps to some degree in functionality and data related to maintenance follow up and improvement. The study indicates some contradicting results regarding IT and functionality for maintenance follow up and improvement. Some users state that there is a need for additional IT-support related to maintenance follow up and improvement while other state that the support exists but are not used. More in-depth studies of the reasons behind these contradicting results and also research in reasons behind apprehended gaps are required.

    Modular-Based Framework of Key Performance Indicators Regulating Maintenance Contracts2019In: Asset Intelligence through Integration and Interoperability and Contemporary Vibration Engineering Technologies: Proceedings of the 12th World Congress on Engineering Asset Management and the 13th International Conference on Vibration Engineering and Technology of Machinery / [ed] Joseph Mathew C W Lim Lin Ma Don Sands Michael E. Cholette Pietro Borghesani, Springer, 2019, p. 301-310Chapter in book (Refereed)
    Abstract [en]

    Key performance indicators (KPI) are necessary for regulating maintenance performance, setting goals as well as for follow up and improvement. Several standards and models for measuring maintenance performance exist today, but these are mainly developed for in-house maintenance. For outsourced maintenance, which is regulated in a service contract, other kinds of KPIs are needed. The procurement of maintenance and contract forms is also changing; an alternative to the traditional maintenance contract based on fixed price and predetermined activities are the performance-based contracts. Cooperation contracts based on mutual trust and fairness for all parties are also available. New KPI models for regulating maintenance service contracts are therefore needed. In this paper, a KPI framework for maintenance contracts based on the concept of modular maintenance offerings is proposed. Modular maintenance offerings is a way to classify maintenance services offerings with increasing integration of the offering, and increasing focus on utility for the customer and the business ecosystem. The KPI framework proposes indicators for regulating contracts on three levels (resource, performance and utility level) and includes six categories of indicators: economic, technical, organisational, quality, safety and health, and relationship between actors.
