dc.description.abstract | The case company in this study is a food processing factory with a variety of products, as many as 95 types. While the demand is high,the management will become more important ,and the product quality, cost,and and delivery time of each product must be consider more seriously, even in achieving customer trust and meet the customer needs, Therefore I expect to use value stream mapping (value stream mapping, VSM) to analyze the entire process, starting from the supplier, the production process to the customer, improve from a comprehensive perspective, to find out the problem points, and reduce waste in the process, optimize the production lprocess, promote production efficiency, and reduce the lead time of delivery, etc.,then use the simulation software Flexsim to establish the model of the current production line,use the charts and data output from the Flexsim as one of the references for analyzing the current situation of the production line,and use the company current OEE two as an value refer to set improvement goals, the benefits of improvement are initially checked through from the future value stream mapping,then establish 7future improvement simulation model, checks whether the improved benefits have achieved the expected improvement or not, and also compares the improvement of before and after, At the same time, all improvements are evaluated in three items, which are OEE (Overall Equipment Effectiveness, which is the overall equipment effectiveness) loss items, improvement range and cost, and the improvement items will be given a comprehensive evaluation score, The first three improvements are selected with lower cost and bring greater benefits,then finally provides the entire process and improvement plan to U company for reference, assisting the company in process improvement and refinement direction. | en_US |
