Magister Commercii - MCom / This research project focuses on the application of process improvement techniques in a clothing manufacturer to address delay problems in workflow in the factory. The objective of the research is threefold; investigate delays at the beginning of production and make suggestions, show the usefulness of continuous improvement techniques in improving activities in a clothing manufacturer and demonstrate how action research can be used in doing research in production and operation management. Using tools such as flow charts, check sheets, pareto analysis, fishbone diagrams, interviews and the "ask why five times" tool, an investigation into delays led to a second investigation into sewing defects. This established that these sewing defects are caused mainly by time constraints, the malfunctioning of machines, the wrong handling of garments, and previous operations. After an investigation using the above tools it was established that these defects could be addressed by setting realistic targets, doing regular maintenance on machines, cautioning operators to be more careful during their operations, and encouraging regular checks on garments before the next operation. The action learning methodology led to the following lessons; selecting a correct measuring tool is important, that not all tools need to be used, and that it takes time to do a research project using this method.

Detta examensarbete grundar sig på Lean-filosofin och genomförs i samarbete med ett legotillverkande företag vid namn Gloab Konsult AB, som specialiserar sig i CNC-svarvning och precisionsslipning. För att mer i detalj kunna studera olika verktyg och metoder ifrån Leanfilosofin, är syftet med detta arbete att effektivisera en av Gloabs artiklar som går igenom hela deras produktion, från råvarulager till längdsvarv och robotstyrd-precisionsslipmaskin för att slutligen packas ner för leverans till kund, en M2-500. Arbetet börjar med att identifiera flaskhalsen samt de icke-värdeadderande moment (Leans 7+1 slöserier) i M2-500:as flöde med hjälp av en flödesanalys. Detta ledde till att ett spagettidiagram, en 5-varför, en SMED-analys samt ett fiskbensdiagram användes för att identifiera, samt reducera orsakerna till Leanslöserierna transport, rörelse, väntan och outnyttjad kompetens, men också för att effektivisera och reducera flaskhalsen i flödet. Förbättringsförslagen som presenteras innefattar att flytta närmare på råmaterialet, införskaffa ett nytt mellanlager, påbörja arbete med 5S, utbilda fler personal, samt tillämpa SMED på maskinen som utgör flaskhalsen i M2-500:as flöde. / This thesis is based on the Lean philosophy and is conducted in collaboration with a contract manufacturing company called Gloab Konsult AB, specializing in CNC turning and precision grinding. In order to study various Lean tools and methods in more detail, the purpose of this work is to streamline one of Gloab's products that goes through their entire production process, from raw material storage to length turning and robot-controlled precision grinding machine, and finally packed for delivery to the customer, an M2-500. The work starts by identifying the bottleneck and non-value-added activities (Lean's 7+1 wastes) in the flow of the M2-500, using a flow analysis. This led to the use of a spaghetti diagram, a 5-why analysis, a SMED analysis, and a fishbone diagram to identify and reduce the causes of Lean wastes such as transportation, motion, waiting, and unused skills, as well as to streamline and reduce the bottleneck in the flow. The proposed improvement suggestions include moving closer to the raw material, acquiring a new intermediate storage, implementing 5S, training additional personnel, and applying SMED to the machine that represents the bottleneck in the flow of the M2-500

Yes / Overall equipment effectiveness (OEE) is a key indicator to measure the effectiveness of production systems. This paper aims to evaluate and improve a plastic production line based on OEE evaluation. An integrated framework is proposed to enhance the production system efficiency. This paper presents the data for a Plastic production line in Jordan under real working conditions. The data covers three months. A framework process to improve the OEE of the Plastic production system was proposed. Six major stoppage losses were inspected with the help of Pareto analysis. Furthermore, the actual availability, efficiency, and quality rate measures, together with the whole OEE for each working day, week, and month of the production line were shown. The methodology is based on determining the OEE of a Plastic production line after determining the causes of failures. The fishbone diagram tool is used to determine the root causes of failures. To improve the OEE measure, several losses are identified. The results reveal that the company should improve its policy to improve the production line’s performance and reduce losses. Top management should also pay attention to reducing the speed losses, which consist of 58.1%, and eliminate the planned and unscheduled disruptions covering 12.73% of all losses. This can be achieved by establishing a proper operation management procedure and strategy. This, in turn, optimized the equipment’s effectiveness. The quality procedure should include the changeover program that may be executed every day. Similarly, all preventive maintenance procedures for the six machines should be properly executed in predetermined intervals. There are several limitations in the research. Firstly, the research case study is only the plastic production system. Secondly, the research is related to the downtime or stoppage by analyzing it using fishbone diagram. Further, supported by other techniques such as the Pareto chart, six big losses analyses and CED. This research conducted on a Plastic industry. However, similar studies can be carried out in future in other manufacturing industries like electronic, pharmaceutical, textile industries, etc., and service industry. However, as future research work the contributions of this paper with other lean manufacturing concept like six sigma, quality function deployment, TQM, and just-in-time manu-facturing, can also be conducting to assess the overall production line efficiency. On the other hand, several statistical tests can be implemented based on data collected of TPM performance indicators. The proposed method supports policymakers in their decision-making process on the operations management line. Further-more, it improves the production systems’ productivity quality, and performance, reducing unplanned stop-pages and breakdowns, and reducing maintenance costs.

With the globalization era, software companies around the world not only have to face competition in the domestic industry, as well as the subsequent challenge of large international companies. For this reason, domestic software companies must to upgrade their own software quality. Domestic government agencies and non-governmental units together promote Capability Maturity Model Integration (CMMI). Hope to improve their quality of software development process through internationalized professional evaluation. Towards the high-maturity software development process, software development process should be estimated quantitatively in CMMI Level 4. There are frequently used statistical process control (SPC) methods, including control charts, fishbone diagram, pareto charts ... and other related practices. Its goal is to maintain stability of overall software development process, so the output performance can be expected. Primitive SPC applied in manufacturing industry, successfully improving the quality of their products. But some characteristics of software, such as software development is human-intensive and innovative activities. It increases not only variability of control, but also difficulties of implementation. In this study, collate and analyze the operational framework of SPC and CMMI Level 4 through study of literature and case study with the case company-A company's practices. It contains two points, one is organization point of view, the other is methodological point of view. Organizational point of view includes stage of CMMI Level 4 and SPC implemented in the software industry, as well as how to design the organizational structure. Methodological point of view includes the steps to run SPC¡Buseful methods and tools. Methodological point of view also uses control theory to collate relevant control mechanisms. Finally, we illustrate how to integrate SPC into the company's system development life cycle. The framework can provide a reference for domestic software companies of longing for implementing CMMI Level 4 and SPC.

The problem being researched. The integration of Middle and Eastern European states into democratic processes has determined changes in public sector management and with rationalization of sectors of Lithuanian economy the system of justice was also involved: in the year 1993 the Parliament approved the outlines of the reform of the system of justice which set that legal bases of the reform have to be formed, specialists are to be prepared employees selected, the necessary financial and economical basis created, new legal institutions have to be created and the old ones reformed in order to ensure the stable system of justice. The reform has revealed both the advantages and disadvantages of the system of justice: not all the areas of the system of justice have received the appropriate attention. A similar situation occurred when carrying out the outlines of the Reform of the System of Justice approved in the year 1998. An appropriate and effective functioning of legal proceeding has been emphasized in international acts of law and experts’ meetings: democratization of management of prosecution system and improvement of the legal regulation of its management as well as more operative fulfillment of its functions are necessa ry; the reorganization has not only to strengthen prosecutors’ professionalism but also to ensure the adequate working conditions. This position was approved by the resolutions of the Tenth Congress of the United Nations which took place in Vienna on the 1... [to full text] / Tiriamoji problema. Vidurio ir Rytų Europos valstybių įsijungimas į demokratinius procesus sąlygojo viešojo sektoriaus valdymo pokyčius, o racionalizuojant Lietuvos ūkio sritis, nebuvo aplenkta ir teisinė sistema: 1993 m. Seimas patvirtino Teisinės sistemos reformos metmenis, kuriose nustatyta, kad turi būti formuojami reformos teisiniai pamatai, rengiami specialistai, renkami darbuotojai, kuriama būtina finansinė–ūkinė bei materialinė bazė, pertvarkomos bei kuriamos naujos teisinės institucijos, kurios užtikrintų stabilią teisinę sistemą. Reforma atskleidė tiek teisinės sistemos privalumus, tiek ir trūkumus: ne visoms teisinės sistemos sritims skirtas tinkamas dėmesys. Panaši situacija susiklostė ir įgyvendinant 1998 m. patvirtintas Teisinės reformos metmenis. Ne vieną kartą tinkamas ir efektyvus baudžiamosios teisenos funkcionavimas yra akcentuotas tarptautinės teisės aktuose bei ekspertų susitikimuose: būtinas prokuratūros sistemos valdymo demokratizavimas, jos veiklos teisinio reglamentavimo tobulinimas bei operatyvesnis funkcijų vykdymas, reorganizacija turi ne tik stiprinti prokurorų profesionalumą, bet ir užtikrinti adekvačias darbo sąlygas. Šią poziciją patvirtina 2000 m. balandžio 17 d. Vienoje vykusio dešimtojo Jungtinių Tautų Kongreso dėl nusikaltimų prevencijos bei elgesio su nusikaltėliais sprendimai, kuriais buvo konstatuota, jog tinkamas baudžiamosios teisės sistemos administravimas yra viena iš efektyviausių kovos su nusikalstamumu priemonių. 2002 metų...

This diploma thesis deals with application of quality tools in production plant. Theoretical part deal with history of quality, current situation in quality management and describe some of quality tools. In practical part will be applied some of described quality tools. Some of them are already implemented in production but only partially and they are not used in full for more flexible and efficient production. Conclusions and results of this diploma thesis should prove that if we are using these tools in full, we can decrease extra cost in production.

<p>Detta är ett naturvetenskapligt arbete som omfattas både av en kvantitativ och en kvalitativ undersökning. Syftet med arbetet är att undersöka mellanskarvens födoval i sjön Sommen, samt att närmare studera huruvida det unika beståndet av röding och öring ingår i mellanskarvens födoval. Sommens Fiskevårdsområde har fått tillstånd till skyddsjakt på mellanskarv av Länsstyrelsen och det främsta skälet skulle vara att fågeln prederar röding och öring. Genom att analysera mellanskarvens spyboll och jämföra innehållet med referensfiskar fångade från samma sjö ska vi se om beslutet från Länsstyrelsen är befogat. Insamling av spybollar och referensfiskar utfördes i fält medan analys av spybollar utfördes på laboratorium. I resultatet av undersökningen konstaterades att mellanskarven i Sommen nästan uteslutande äter abborre. I de analyserade spybollarna som omfattas av denna undersökning återfanns inte röding och öring. Detta skulle innebära att Länsstyrelsens beslut om skyddsjakt på mellanskarv i Sommen p.g.a. predation av röding och öring inte är befogad.</p>
