Measuring For Improvement: A study of production processes’ effectiveness and the potential for improvements at Nobel Biocare

Ben Or, Yaniv January 2010 (has links)
Purpose: this thesis study aims to provide an analysis and an assessment of the current operations’ performance effectiveness at Nobel Biocare’s production plant in Karlskoga, Sweden and to describe the potential for improvement. It intends to clarify the importance of performance measurement and explain Overall Equipment Effectiveness (OEE) metrics in particular.Furthermore, it strives to identify causes for inefficiency in production and suggest recommendations to minimize losses. Methodology: the study is using both qualitative and quantitative approaches in parallel as measurements are implemented to discover effectiveness rates and detect causes for production losses while assessments are made using different models, such as the Capability Maturity Model(CMM) and OEE assessments, in order to evaluate the current development level and the potential for improvement. Findings: the research finds that major losses are closely related to frequency of changeovers in machining processes, where average effectiveness rates were 68%. In surface treatment and packaging equipment inspected, the values were found to be between 46% and 59% as the major common cause was the absence of work due to unstable flow of orders. Assessing process orientation and maturity levels, the findings indicate on high levels in general. However, areas of weakness were identified in the different processes in which the potential for improvement is embedded. In those areas, lower OEE values were registered; low levels of maturity and process orientation were found, as low development of losses improvement were assessed. The study finally suggests that the areas of weakness suffer from lack of learning orientation that is ought to be improved and at the same time, a variety of specific recommendations are provided.

Utvärdering och Implementering av underhållssystem : Evulation and implementation of a Maintenace Management System

Svensson, Ulrika January 2006 (has links)
Detta examensarbete beskriver hur förarbetet till att datorisera ett underhållssystem genomförs. Uppdragsgivare är Lear Corporation i Torslanda. Examensarbetet består av två delar: utvärdera en på förhand vald programvara och att dokumentera allt förebyggande underhåll (FU). Syftet är att få bättre kontroll och planering av förebyggande underhåll (FU) i framtiden. Programvaran som skall utvärderas om den är lämplig för ändamålet heter Tekla™ Maintenance. Målet var att dokumentera allt förebyggande underhåll (FU) för två av tre liner i Lear Corporations fabrik i Torslanda. Det visade sig att Tekla™ Maintenance uppfyllde de krav som fanns. De krav som fanns var bland annat när det var dags att göra ett förebyggande underhållsarbete ska programmet automatiskt tala om att nu skall det utföras. Ett användarvänligt gränssnitt var också efterfrågat. Rapporten innerhåller även en beskrivning av hur Tekla™ Maintenance är uppbyggt. För att få en bild av hur det är att arbeta med programmet i verkligheten genomfördes en benchmarking mot Plastal AB. Plastal AB hade mycket goda erfarenheter av att arbeta med programmet och kunde därför varmt rekommendera det. All dokumentation av förebyggande underhåll sker i dag på papper. Eftersom denna dokumentation inte innehöll tillräckligt med information skedde nedbrytningen från grunden. Varje line delades in i mindre områden så som line, kringutrustning och moment- och skruvdragare. När allt var dokumenterat fick underhållspersonalen tala om vad för slags förebyggande underhåll som skulle göras på all utrustning. Allt skrevs in i en Excel-fil som skall användas för att importera informationen till Tekla™ Maintenance i framtiden. Filen innerhåller över 2000 stycken objekt, vilket ger en bra grund för underhållsarbetet i framtiden. / This Bachelor Thesis deals with how to prepare a computerization of a Maintenance Management System. The Bachelor Thesis is written by commission at Lear Corporation in Torslanda, Sweden. The paper is divided into two parts: evaluate a software and document all preventive maintenance. The purpose is to get better control and planning of preventive maintenance in the future. Tekla™ Maintenance is the software that is going to be evaluated. The aim is to document all preventive maintenance for two of three production lines at Lear Corporations factory at Torslanda, Sweden. The research shows that Tekla™ Maintenance met the specifications. One of the basic requirements was to automate the management of prevention maintenance activity, by issuing work order. Furthermore a user friendly interface was required. A description of Tekla™ Maintenance is included in the report. To get a feeling of how the programme perform in real world, benchmarking was preformed against Plastal AB. The benchmarking resulted in that Plastal AB recommended the Tekla™ Maintenance programme. Currently the documentation does not contain enough detailed information to allow a thorough review of all production lines. By dividing all lines into zones, all activities at each zone have been documented. Feedback form the operators was given, about what type of preventive maintenance that is required. To be able to put all the information into Tekla™ Maintenance, an Excel file has been made. This file contains over 2000 entries and should provide a solid base for future preventive maintenance.

Maintenance management for effective operations management at Matimba Power Station / Oufa Ernest Mutloane.

Mutloane, Oufa Ernest January 2009 (has links)
Effective and efficient operations management is the cornerstone of any company's success. Presently, because of cost-cutting pressures, all investors look out for companies' operations before making any investment commitment. The South African Government (through the Department of Public Enterprises), as an owner and investor in Eskom, is looking at optimising operational excellence within state-owned enterprises like Eskom. Eskom is presently experiencing problems with increased electricity consumption which it cannot meet due to the limited plant capacity it presently has. These challenges are forcing Eskom to be more efficient and effective in management of the present plant assets (like Matimba Power Station) it presently operates. Matimba Power Station has consistently shown improvement in the areas of plant, financial and operations performance over the last three years. It is presently the standard bearer for the whole Eskom in terms of plant and operational performance. Asset management (through maintenance and management thereof), especially preventative management with in a power utility like Eskom, is a critical factor because supply (generation of electricity) has to meet demand (consumption of electricity) instantaneously as electricity cannot be saved. The planning, scheduling and execution of maintenance (through a work management process) to ensure success of business operations are very critical. An Eskom document titled Routine Work Management Manual emphasised the criticality of preventative management and included a six-step process of work management within the power generation business. The Japanese success in ensuring that operations costs are limited by implementing total productive maintenance (which includes work management) is suggested in the study as a way to go for operational success at Matimba Power Station. Many of the research studies done at Eskom in regard to maintenance were based on and confined to a sampling population of senior staff members like managers, engineers and supervisors. Experience has shown that progress of implementing change (whether in systems or structures) is slow if there was no proactive involvement of all participants and stakeholders, especially employees at lower levels involved in operations. A work management process, which is one of the pillars of total productive maintenance, was recently implemented at Matimba and is currently experiencing teething problems which are being attended to. Employee involvement in making sure of the success of work management is critical. The study investigates the implementation of work management from the employees' perspective in order to address problems for possible full implementation of total productive maintenance. / Thesis (M.B.A.)--North-West University, Vaal Triangle Campus, 2010.

Programas de melhoria da produtividade e qualidade: um estudo comparativo dos modelos \"Just-in-Time\" (JIT), \"Total Quality Control\" (TQC) e \"Total Productive Maintenance\" (TPM). / Productivity and quality improvement programs: a comparative study of Just-in-Time (JIT), Total Quality Control (TQC) and Total Productive Maintenance (TPM) models.

Dario Ikuo Miyake 10 September 1993 (has links)
O aumento da competitividade no mercado tem estimulado uma grande busca por conceitos e técnicas que auxiliem os processos de melhoria do desempenho de sistemas produtivos, sobretudo no que tange a produtividade e qualidade. Neste contexto, o estudo da experiência das indústrias japonesas revela que a sua competitividade foi conquistada e tem sido sustentada com base em modelos integrados voltados ao planejamento, implementação e condução dos chamados programas de melhoria da produtividade e qualidade (PMPQ\'s). Tais modelos são baseados em filosofias especificas de gestão da manufatura, sendo que os três seguintes, despontam com grande destaque e constituem o objeto central de estudo desta dissertação: 1. Manufatura Just-in-Time (JIT); 2. Total Quality Control (TQC); 3. Total Productive Maintenance (TPM). O presente trabalho é dedicado ao estudo conceitual destes modelos. Para isso foi elaborado um quadro conceitual sobre a estrutura geral de um PMPQ. Tomando-se este quadro como pano de fundo, estes três modelos foram então caracterizados, analisados e avaliados de forma comparativa. Esta análise possibilitou a identificação dos aspectos específicos a cada um, más também evidenciou muitas semelhanças (exemplo: sua aplicação como instrumento de gestão estratégica da manufatura) entre os mesmos. / Along the last decades a series of geopolitical and macroeconomic changes have made the competition in international trade tougher. Although the brazilian economy has not been so integrated to the international market, effects of such trend are already disturbing the dynamics of Braazilian companies. Therefore an increasing number of companies have driven themselves into processes aimed to increase competitive power through strategies that value mainly attributes like cost and quality. Such processes have in general a broad scope and are usully called Productivity and Quality Improvement Programs (PQIP\'s). In this context, new paradigms for planning, implementation and guidance of such programs have risen from japanese industries. Among these paradigms, three of them are worthy of special attention and represent the main object of this work. Each of these paradigms have their own manufacturing management philosophy and are the following; 1. the paradigm based on Just-In-Time (JIT) Manufacturing philosophy, 2. the paradigm based on Total Quality Control (TQC) philosophy and 3. the paradigm based on Total Productive Maintenance (TPM) philosophy, This work is dedicated to the conceptual investigation of these paradigms. First, a conceptual framework for the general structure of a PQIP was built. Then it was taken as a frame in order to present, analyse and evaluate comparatively the three paradigms. The investigation resulted in the recognition of features that are unique to each one but it also exposed many similarities among them. One commom feature is that all three admit their use as a tool for strategic management of manufacturing, an activity that has been overlooked by western industrial companies organized and managed in traditional way. The investigation also revealed a clear resolution of these paradigms to search the achievement of economic objectives of a firm without confronting and neglecting the social and humanistic demands expressed by the human resources engaged in production.

The impact of total productive maintenance (TPM) on manufacturing performance at the Colt Section of DaimlerChrysler in the Eastern Cape

Ncube, Mfowabo January 2006 (has links)
Today's successful manufacturing organisations require a significant competitive advantage, hence the need to implement and develop a Total Productive Maintenance (TPM) strategy. This research paper addresses the impact of TPM on manufacturing performance at the Colt production facility (DCSA). A literature survey was undertaken into the elements and benefits of TPM. Questionaires were also sent to all levels of people at the Colt production facility for their views on TPM and the impact, they believe, it has had on manufacturing performance. In conclusion, this research paper has also led to the development of recommendations to improve TPM activities at the Colt production facility. From the research, it was shown that top management support for TPM activities is needed and that training is an essential factor for TPM's success in improving manufacturing performance.

The factors that hinder the overall equipment effectiveness at Ford Struandale Engine Plant

Qweleka, Sazile January 2009 (has links)
This treatise investigates the underlying factors that are hindering the improvement of Overall Equipment Effectiveness at the Ford Struandale Engine Plant. In January of 2008 the Ford Motor Company announced plans to invest more than R1.5 billion to expand operations for the production of Ford's next-generation compact pickup truck and the PUMA diesel engine. Ford will use the investment to expand operations both in Silverton for the production of 75 000 units of a new bakkie and in Port Elizabeth for 220 000 units of its new-generation PUMA diesel engines (http://www.autoblog.com /2008/01/31/ford-to-invest-209m-in-south-africa-for-new-ranger-pickup/). Only five Ford plants globally will be producing the PUMA engine (Turkey, UK, Thailand, Argentina and South Africa – Ford Struandale Engine Plant). The Ford Struandale Engine Plant will be the only plant which will have the I4 assembly, I5 assembly and 3C (Crank, Cylinder Block, and Cylinder Head) machining and the expectations of operating in a lean environment is high. The management team at the Ford Struandale Engine Plant needs to understand what the underlying factors that are hindering the improvement of Overall Equipment Effectiveness of the plant or, in other words, they need to be informed of the total benefits of TPM. A literature review was conducted to determine what the theory reveals about Overall Equipment Effectiveness, the three factors of OEE (Availability, Performance Efficiency, and Quality), the influence of Six Big Losses on each of the factors and the role of Total Productive Maintenance in improving OEE by eliminating these Six Big Losses. A Ford literature study was conducted to reveal the current literature being applied at Ford. This was then followed by an empirical survey conducted within the Ford Struandale Engine Plant. In addition, a task team formed to analyse the current maintenance operating strategy. Finally, the findings from discussions with the task team, the empirical survey, Ford Struandale Engine Plant literature survey and a general literature survey were amalgamated to draw conclusions relating to the Ford Struandale Engine Plant. These conclusions indicate what the underlying factors are that are hindering the improvement of Overall Equipment Effectiveness of the Ford Struandale Engine Plant facilities and equipment. Then recommendations are made as to how the Ford Struandale Engine Plant can improve the Overall Equipment Effectiveness of its facilities and equipment.
