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.

The Application of System Dynamics Based DSS for Integrated Coastal Zone Management in Nanwan, Kenting National Pare

Hong, Feng-Wei 08 July 2004 (has links)
Abstract Kenting National Park is the only national park in Taiwan related to the ocean. There are abundant marine resources, such as diverse coral species, which attracted many kinds of fishes. This coral reef ecosystem is well-known to it¡¦s high productivity, and high recreational value. It attracts millions of tourists every year. For the goal of sustainable development, the coast zone of Nanwan should be managed based on integrated perspectives. System dynamics is an approach that is used to describe, explore and analyze the procedure, information and the boundary of organizations in complex systems. Through the process of quantitative model simulation and analysis, we could understand the structure and behavior of a system. Such model is good for solving dynamic complex problems with non-linearity, causal circulation, information feedback and time-delay. The coastal zone management in Nanwan involves four intricate components, including the tourism, environment, ecosystem and the management, the complexity of the system has made it suitable to be solved by a system dynamic model. The model was built as a decision support system. According to the nature of the problem, the SD model was divided into four subsystems: social-economic subsystem, environment subsystem, biologic subsystem and management subsystem. To function as a decision support system, a user-interface was built, to allow user interact with the model, alter parameters and run simulates. The result of the simulation can provide good supporting imformation for decision makers. Four vital variables regarding the management scenarios, in cluding land development, wastewater treatment, fishing restriction, and surcharge fare, are presented to users in the user-interface. Users can adjust those variables and run a simulation to evaluate the impact under different configuration. Based on the current research, some preliminary results were found, such as this area is not suitable for heavy land development, meanwhile, adding wastewater treatment facility, restricting fishing activities, and implementing tourist charge, are useful to mitigate the human impact. As for design and enforcement of management policies it would rely on the experience and ability of the decision maker.

Tu, Chiang-Kuo 17 July 2004 (has links)
The Balanced Scorecard (BSC) facilitates managers to balance strategic focuses on four perspectives, on complex cause and effect relationships, and on developing more systemic aligned strategy. But some literatures showed that the BSC theory and practice had some limitations. The root of limitations is ¡§cause and effect are not closely related in time and space¡¨. And that will mislead managers to generate misperceptions of feedback information and execute wrong strategy. This research employs system dynamics as a method to overcome the limitations, and focuses on exploring the dynamic complexity of developing the BSC strategy. By two case studies, this research finds some opinions to conceptualize a theoretical framework, generate some dynamic pitfalls propositions, and summarize some dynamically aligned principles. By system dynamics method, this research builds qualitative and quantitative system dynamics models and inquires the cases¡¦ BSC strategy. And by case study method, this research follows qualitative research perspective to compare two cases and generate propositions. The conclusion, firstly, includes a conceptualized framework of ¡§improving the dynamic alignment of the balanced scorecard strategy in system dynamics¡¨, to support ¡§the theory of developing BSC with system dynamics¡¨ and enhance the long-term effectiveness of BSC strategy. Secondly, this research finds some dynamic pitfalls propositions. Lastly, this research discusses some implications on management, limitations, and future research.

The Validity Problem of Reverse Engineering Dynamic Systems

Chen, Jian-xun 15 August 2006 (has links)
The high-throughput measurement devices for DNA, RNA, and proteins produce large amount of information-rich data from biological dynamic systems. It is a need to reverse engineering these data to reveal parameters/structure and behavior relationships implicit in the data. Ultimately, complex interactions between its components that make up a system can be better understood. However, issues of reverse engineering in bioinformatics like algorithms use, the number of temporal sample, continuous or discrete type of input data, etc. are discussed but merely in the validity problem. We argue that, since the data available in reality are not so perfect, the result of reverse engineering is impacted by the un-perfect data. If this is true, to know how this impacts the results of the reverse engineering and to what extent is an important issue. We choose the parameter estimation as our task of reverse engineering and develop a novel method to investigate this validity problem. The data we used has a minor deviation from real data in each data point and then we compare the results of reverse engineering with its target parameters. It can be realized that the more error in data will introduce more serious validity problem in reverse engineering. Three artificial systems are used as test bed to demonstrate our approach. The results of the experiments show, a minor deviation in data may introduce large parameter deviation in the parameter solutions. We conclude that we should not ignore the data error in reverse engineering. To have more knowledge of this phenomenon, we further develop an analytical procedure to analyze the dynamic of the systems to see which characteristic will contribute to this impact. The sensitivity test, propagation analysis and impact factor analysis are applied to the systems. Some qualitative rules that describe the relationship between the results of reverse engineering and the dynamics of the system are summarized. All the finding of this exploration research needs more study to confirm its results. Along this line of research, the biological meaning and the possible relationship between robustness and the variation in parameters in reverse engineering is worth to study in the future. The better reverse algorithm to avoid this validity problem is another topic for future work.
