Implementation Efficiency Analysis of JIT Kanban System in Machinery and Equipment Manufacturing.Chen, Jyun-Liang 17 June 2011 (has links)
Most of machine industry in Taiwan use ¡§Build to order¡¨ which start the production process until receiving orders. The key of ¡§Build to order¡¨ can be successful or not is quickly response to demand changes. If the production system can¡¦t keep up with changes in customer demand, it won¡¦t be able to process successive demands. Then the backlog will be more and more. So in ¡§Build to order¡¨, whether production system can adjust for changes in customer demand quickly or not is an important issue of ¡§Build to order¡¨.
Kanban System is a mode of production which Toyota JIT system develops. It uses kanbans to control capacity of each workstation strictly. In order to achieve pull system, it uses kanbans to authorize production. Traditional push system must change production plans frequently, and maintain a certain stock between production processes. Pull system uses demands of back-end process to pull the production of front-end process. To achieve the so-called ¡§Just-in-Time¡¨ concept, the system must output the right number of products at the right time.
This study uses system dynamics. According to relevant literatures and models, this study constructs Kanban system with industrial properties. According to demand changes and number of kanbans, this study simulates and analyzes the effectiveness after implementing the Kanban system. Then this study makes some management recommendations.
Conclusions and findings:(1)Under the situation of normal demand changes, Kanban system can achieve quickly response and stability of production systems.(2) Under the situation of excessive changes in demand, implementing Kanban system will increase the backlog.(3)The number of kanbans represents production needs which are additional planned. The system should minimize the number of kanbans to avoid wastes.

A Study of Key Successful Factors to Lead Lean Production for Power Plant Operating ManagementSun, Chun-chi 18 May 2012 (has links)
In recent years, due to the influence of international energy supply and demand change, the request of carbon reducing lead by the climatic change, and the security issue from Japanese nucleus accident, push us have to develop multi-type power units; These results carries the power generation ways not only depend on the nuclear power, the coal-fire, the fuel oil or the hydrualic power, but also distribute partial demand to the gas turbine with combined cycle, the wind power, the solar energy and so on. If power plants have still to maintain high quality to produce and reduce the cost, its method of management also adjust to meet.
The lean production is a famous way study and compile by many experts from the Toyota-type production which becomes the business model to enterprise, it emphasis that keep people to improve and the continue flow oriented , is precisely study model which the power plant management most needs now. This research is take a diversity power plant as the research case, by visits and measures that in the power plant each kind of experts. The lean production will induct the power plant production management to the lean production management concept's cognition and the inquisition, the attempt seeks improves the power plant management achievements the important key success factor, and the construction leaves the fine solid management mechanism. After collects various experts' questionnaire material, by the AHP level analysis method, the induction research obtains the following conclusion,
First, the power generation process is real pull system, the demand carries by the customer (household power user) - the contribution center (to represent) proposed that initiates a serial electric power generation processes.
Second, If considering the cost and quality factors with understanding and research of the operation, maintenance, manages experts , we get that the lean production way is truly suitable to fulfill in the power plant generation process, it¡¦s key point :
1.Should devote in formulate the work flow standardization, strengthens ability of the operators and maintain steady supply of fuel, find the good maintenance procedure, keep the production to be smooth.
2.Should participate in the improvement activity diligently including operator's all personnel, as well as promotes the power plant business to ability of the unit performance analysis, understood the characteristic of each production process, pursues the highest efficiency, expect to reduce the cost, and goal the quality promotion.
3.After the experts¡¦ decision-making process, we can involve the essential factor of lean production to be the management construction of power plant, but the case power plant has initially had the essence solid state.
Key words: Lean production, the Toyota-type production, pull system , AHP, the standardization

Reducing WIP Inventory of Production Line in AQ Segerström & Svensson ABYuvaraj, Vasanth Raj, Zhang, Sifei January 2013 (has links)
The major objective of present study is to find out the sources which cause higher Work in Process (WIP) in the production line. In which a detailed analysis is performed in the area of inventory, reorder point, Takt time, and Kanban. All the analyses are based on the data obtained from the company’s ERP system and have been used to run some scenarios during the analysis.Lots of problems are responsible to cause higher WIP. But current report only focuses and concentrates in leveling the work load, implementing pull system, suggesting reorder point and Takt time.The current situation is described through Value-stream Map (VSM) and the impact cost matrix is used to show the impact of each problem in the production line in terms of costs. In the analysis chapter, root cause method has been used in order to show the cause and effect of higher WIP. Detailed analyses together with explanations are listed by orders. Therefore, three major suggestions are proposed and the future VSM is plotted to show the effect and change of the suggestions which helps to improve the current situation by eliminating the waste.

A Conwip Application In An Electronics CompanyGungorer, Elif 01 February 2010 (has links) (PDF)
In this thesis, a real world application of the constant work in process (Conwip) system in an electronics company is realized. The aim of the application is to reduce the work in process (WIP) inventory while maintaining the same throughput level. A model is developed to determine the constant work in process level of the Conwip system for the production lines in this company. The approximated mean value analysis approach is used for the solution. Real system data are collected before and after the Conwip application. Hypothesis tests are used to compare the WIP and the throughput levels of the Conwip system with the existing push control system for a pilot production line. Results of the hypothesis tests show that the Conwip production control system can signinifcantly reduce the WIP while maintaining the same throughput rate.
