Luleå, April 2003 Fredrik Backlund II ABSTRACT Due to a competitive environment, many companies are required to reduce their overall costs while maintaining the value and reliability of their assets. The use of Reliability-Centred Maintenance, RCM, can help organisations to develop a systematic maintenance programme, meeting these requirements in a cost- effective manner. RCM basically combines different techniques and tools in a systematic approach to manage risks as a basis for maintenance decisions. When introducing RCM with the aim of changing the overall way of working with maintenance in the organisation, i.e. on a full-scale basis, a long-term introduction approach should preferably be used. In addition to improving the performance of the assets, this approach uses RCM to improve knowledge, motivation and teamwork among the personnel. In this way the approach could increase the commitment of managers and employees, making an RCM based maintenance programme far more likely to endure. However, in several cases organisations have experienced severe difficulties when introducing RCM on a full-scale basis. Some of the reasons are technical in nature, but the majority are managerial obstacles. In the research project presented in this thesis, an overall aim has been to facilitate for organisations introducing RCM. The focus has been on identifying managerial factors that affect an RCM introduction. In the research project, a longitudinal single-case study has been performed during 1997 - 2003, studying the introduction of RCM in a Swedish hydropower company. Many of the findings in the single-case study have been validated by a multiple-case study, including three other hydropower organisations introducing RCM. The findings are basically different kinds of managerial factors, which affect the introduction in form of obstacles and driving forces. These factors could be managed in four management perspectives, which indicates the need for a holistic approach when managing RCM introduction. An RCM introduction process has also been identified during the research, where the managerial factors can be structured according to different phases. Based on these findings, an RCM introduction strategy framework has been developed, with the aim of facilitating the work of organisations going to introduce RCM. The strategy framework is structured in accordance with the different phases in the RCM introduction process, with requirements and recommendations to be considered in each phase. III IV SAMMANFATTNING I en konkurrensutsatt omgivning tvingas många företag att på en övergripande nivå sänka sina kostnader, medan anläggningstillgångars värde och driftsäkerhet måste bibehållas. Med hjälp av ”Reliability-Centred Maintenance”, RCM, kan ett systematiskt och kostnadseffektivt underhållsprogram uppnås. RCM består av olika tekniker och verktyg som på ett systematiskt sätt kombineras i syfte att fatta riskbaserade beslut om underhållsinsatser. När RCM införs med syftet att förändra underhållsutförandet i hela organisationen bör ett långsiktigt angreppssätt användas. Ett sådant angreppssätt fokuserar på att förbättra anläggningstillgångars prestanda, men också på ökad kunskap, motivation och samarbete bland medarbetarna i organisationen. På detta sätt ökar sannolikheten för att ett RCM-baserat underhållsprogram kommer att användas och förbättras även efter införandet. Många organisationer har dock upplevt införandet av RCM som problematiskt och svårt. Detta beror till viss del på problem av teknisk karaktär, men tycks till övervägande del röra sig om problem med att styra och leda införandet. Ett övergripande syfte med forskningsprojektet har varit att underlätta för organisationer att införa RCM. Projektet har fokuserat på att identifiera faktorer som är hindrande eller drivande vid införandet av RCM. I en longitudinell fallstudie, genomförd mellan 1997-2003, har införandet av RCM i en svensk vattenkraftsorganisation studerats. Observationerna från fallstudien har validerats med observationer från en multipel fallstudie. Studien omfattar tre andra vattenkraftsorganisationer som befinner sig i införandet av RCM. Resultaten utgörs av olika faktorer som kan delas in i fyra ledningsperspektiv. Resultaten visar på att en helhetssyn måste ligga till grund för att leda och styra ett införande av RCM. En införandeprocess för RCM har också identifierats där faktorerna kan struktureras i olika faser. Baserat på fallstudieobservationerna har en övergripande införandestrategi utvecklats. Strategin har till syfte att underlätta för organisationer att införa RCM, speciellt inom vattenkraftsindustrin. Strategin innefattar krav och rekommendationer att ta hänsyn till i införandeprocessen.

Leadership, Involvement of personnel, Process approach, Systematic approach to management, Factual approach to decision making and Continual improvement are some the main basic principles for these standards. These standards help the organisations to have a common mode of communication for dealing with all stakeholders and merge with the global economy. Instead of implementing all these five standards individually, an integrated approach for implementation can save time and efforts. For this a standard methodology using flow charts and a simple software is developed to help facilities get certified by checking whether the management systems comply with the required standards.

    A Framework for Applying Total Quality Management Standards in Higher Education Institutions of King Khalid Universities By Dr. Abeer Mahfouz Muhammed Al Mdawy Assistant Professor of Educational Planning and Administration Saudi Arabia – Abha King Khalid University Faculty of Education for Girls Department of Basics of Education Journal of Faculty of Education No (113) January, Part (1), 2018 A Framework for Applying Total Quality Management Standards in Higher Education Institutions of King Khalid Universities By Dr. Abeer Mahfouz Muhammed Al Mdawy Assistant Professor of Educational Planning and Administration Saudi Arabia – Abha King Khalid University Faculty of Education for Girls Department of Basics of Education Introduction: In this era, most countries of the world are interested in quality in educational institutions, especially developed ones as they have succeeded in applying quality in their industrial institutions. This is through improving production and goods for the customers' satisfaction. This affects directly the institution profits and its ability to compete with other industrial institutions. Therefore, there is a need to reform and develop educational institutions in light of quality as it is a global transformation from financial to intellectual investment accompanied with big changes in the demands of communities and their competition to obtain better kind of education with graduates who are able to effectively serve their community. (Al Hariri, 2010: 223) Quality in education is one of the vital issues in the current educational system. Higher education institutions, in most countries of the world, are concerned with adopting quality as an approach. The previous programs showed limited improvement in the academic performance in schools and universities.

  • Chapter-4 SYSTEM of TOTAL QUALITY MANAGEMENT
    84 Chapter-4 SYSTEM OF TOTAL QUALITY MANAGEMENT After having discussed the Services of quality circle, this chapter shall discuss System of total quality management. The chapter is presented under the following heads. 4.1 Total Quality Management – An Introduction 4.2 Kaizen 4.3 Six Sigma 4.1 TOTAL QUALITY MANAGEMENT – AN INTRODUCTION Total Quality Management is a management approach that originated in the 1950s and has steadily become more popular since the early 1980s. Total Quality is a description of the culture, attitude and organization of a company that strives to provide customers with products and services that satisfy their needs. The culture requires quality in all aspects of the company’s operations, with processes being done right the first time and defects and waste eradicated from operations. Total Quality Management, TQM, is a method by which management and employees can become involved in the continuous improvement of the production of goods and services. It is a combination of quality and management tools aimed at increasing business and reducing losses due to wasteful practices. Total Quality Management (TQM) refers to management methods used to enhance quality and productivity in business organizations. TQM is a comprehensive management approach that works horizontally across an organization, involving all departments and employees and extending backward and forward to include both suppliers and clients/customers. TQM is only one of many acronyms used to label management systems that focus on quality. Other acronyms include CQI (continuous quality improvement), SQC (statistical quality control), QFD (quality function deployment), QIDW (quality in daily work), TQC (total quality control), etc.

  • Six Sigma Vs. Total Quality Management – Presence in World and Serbian Economy  Udc 005.6(100+497.11)
    FACTA UNIVERSITATIS Series: Economics and Organization Vol. 8, No 2, 2011, pp. 221 - 233 SIX SIGMA VS. TOTAL QUALITY MANAGEMENT – PRESENCE IN WORLD AND SERBIAN ECONOMY UDC 005.6(100+497.11) Marija Anđelković Pešić, Vinko Lepojević, Vladimir Zlatić University of Niš, Faculty of Economics, Serbia [email protected], [email protected], [email protected] Abstract. The Six Sigma concept represents a step forward in the evolutionary development of the approaches for providing competitive advantage based on continuous quality improvement. In that sense, this concept is the successor of Total Quality Management, and, as each new generation surpasses its predecessor, Six Sigma goes beyond Total Quality Management. After implementation of this concept many companies around the world have achieved significant results. Guided by this fact, the aim of this paper is to show the advantages of the Six Sigma concept compared to Total Quality Management. The paper presents data which show presence of the Six Sigma concept in the world economy, but at the same time data from which one can realize the "place" of the Serbian economy compared to the world economy, when it is about implementation of this concept. Key Words: Six Sigma, Total Quality Management, customers, defects, leadership, business culture. INTRODUCTION The appearance of defects is possible in all the processes that take place in an enter- prise. This means that defects occur during: determining the needs and demands of cus- tomers, product design and development, materials and equipment procurement, planning and preparation of production, transport of materials and unfinished products or parts of products, storage of materials and equipment, production process, storage of finished products, sales and distribution, product installation, technical assistance and maintenance and servicing.

  • Kaizen Concept in the Process of a Quality Improvement in the Company
    KAIZEN CONCEPT IN THE PROCESS OF A QUALITY IMPROVEMENT IN THE COMPANY Marcin Jakubiec1 Elwira Brodnicka2 Abstract Following article concerns a topic of quality improvement realized by a concept of con- tinuous improvement – Kaizen. The main goal of the article is to analyze of practical usage of Kaizen, in terms of elimination all waste and continuous improvement. The article is divided into two parts: theoretical and cognitive ones. In the first part of it, the authors described lean philosophy and continuous improvement concept (Kaizen), which are signs to overall com- pany improvement. The cognitive part of the article concerns presentation of practical usage of Kaizen concept rules in chosen automotive sector company. This is a worldwide company with its subsidiary in Poland in Bielsko-Biała. Its main specialization are casts. The company spe- cializes in casting of high complex aluminum components such as: cylinder heads, engine blocks, transmission parts and structural components. The authors used case study method and formulated following research problems: features of Kaizen team, basic rules of Kaizen team, plan of Kaizen action and tools used during Kaizen action. Kaizen actions in analyz- ed company are realized during so-called “Kaizen week”. There is a team built from the company’s employees. As their effect (Kaizen actions) exact solutions of quality problems are formulated. The company leads also so-called “after Kaizen” actions, which are used in a case of problems which require longer time for their elimination. According to the Kaizen philosophy all activities realized in the company in quality area have continuous character. Key words: Kaizen, quality improvement, 5S.

  • Maintenance Approaches for Different Production Methods
    MAINTENANCE APPROACHES FOR DIFFERENT PRODUCTION METHODS D.S. Mungani1 & J.K. Visser2 Department of Engineering and Technology Management Graduate School of Technology Management University of Pretoria, Pretoria, South Africa [email protected], [email protected] ABSTRACT Various production methods are used in industry to manufacture or produce a variety of products needed by industry and consumers. The nature of a product determines which production method is most suitable or cost-effective. A continuous process is typically used to produce large volumes of liquids or gases. Batch processing is often used for small volumes, such as pharmaceutical products. This paper discusses a research project to determine the relationship between maintenance approaches and production methods. A survey was done to determine to what extent three maintenance approaches – reliability- centred maintenance (RCM), total productive maintenance (TPM), and business-centred maintenance (BCM) – are used for three different processing methods (continuous process, batch process, and a production line method). OPSOMMING Verskeie produksiemetodes word deur die industrie gebruik om ’n wye verskeidenheid produkte te vervaardig wat deur die industrie en verbruikers benodig word. Die aard van ’n produk bepaal watter produksiemetode die meeste koste-effektief is. Kontinue prosesse word gewoonlik gebruik vir die vervaardiging van groot volumes gasse of vloeistowwe. Enkelladingsprosesse word dikwels gebruik om klein hoeveelhede van ’n produk te vervaardig, bv. farmaseutiese produkte. Hierdie artikel bespreek ’n projek wat uitgevoer is om die verwantskap tussen instandhoudingsbenaderings en produksiemetodes te bepaal. ’n Meningsopname is gedoen om te bepaal tot watter mate drie benaderings – betroubaarheidgebaseerde instandhouding (RCM), totale produktiewe instandhouding (TPM) en besigheidgebaseerde instandhouding (BCM) – gebruik kan word vir drie alternatiewe produksiemetodes, naamlik kontinue prosesse, enkelladings prosesse, en die produksielyn metode.

The literature on this topic provides divergent opinions. Lean advocates state it is preferable for employees to search for the information they need, as and when they need it, rather than configuring software to provide them with information that is repeated at predetermined times. IT proponents consider Information Technology as a useful tool to support lean practices, for example to deal with complex issues in real-time. This paper gives an overview of the opinions. In addition the process models of lean and ISA 95 are matched. The underlying research question is: does the ISA 95 standard give an appropriate framework to support lean practices; such as Visual Management, Kanban, Value Stream Mapping, Six Sigma, … A preliminary conclusion on their complementarity is made and further research is mentioned.

  • Reliability Centered Maintenance in Schedule Improvement of Automotive Assembly Industry
    American Journal of Applied Sciences 9 (8): 1232-1236, 2012 ISSN 1546-9239 © 2012 Science Publications Reliability Centered Maintenance in Schedule Improvement of Automotive Assembly Industry Rizauddin Ramli and Mohammad Nizam Arffin Department of Mechanical and Materials Engineering, Faculty of Engineering and Built Environment, Universiti Kebangsaan Malaysia, 43600 (UKM) Bangi, Selangor, Malaysia Abstract: Problem statement: Today, in many automotive manufacturing companies, maintenance management is an important factor to maintain the plant operation and production equipments. Approach: In this study, we present an implementation of Reliability Centered Maintenance (RCM) practice in one of the automotive manufacturing company in Malaysia. The RCM practice was used to assist the company in focusing their maintenance activities based on the criticalities of the equipments by applying the Failure Modes and Effects Analysis (FMEA). The implementation of RCM was carried out in 4 stages; preparation, system analysis, decision making and feedback. The aim of RCM was to reduce the number of maintenance checklist and to improve significantly the integrity of maintenance practice. Results: As a result, the new RCM framework was generated where Class A equipment was at the top of the monthly maintenance frequency priority, followed by Class B and Class C equipment which had lesser critical value. Conclusion: The new RCM framework is used to conduct visible guideline and propose a new maintenance schedule. The guideline is useful for future maintenance
