| Summary: | 碩士 === 逢甲大學 === 工業工程與系統管理學系 === 107 === In recent years, the concept of industry 4.0 has become increasingly popular. As labor costs become more expensive, Traditional manufacturing are gradually changing their operation mode. Overall intelligence of the factory must be the trend of the future. Manufacturing procedure is changing from few different styles with large number to many different styles with small number. At present, mechanical automation production is mainly doing a large number of repetitive tasks, and it is necessary to set up the manufacturing procedure and the necessary tools in advance. Multiplicity of work in parallel machines cause long waiting times. The factory must first integrate the operation technology and information system of the internal objects to achieve the goal of intelligent production process.
In this study, Plant Simulation is used to simulate the environment and establish a virtual flexible manufacturing site. In the virtual factory, there are M kinds of non-related parallel machines, which can produce K kinds of products. The purpose of the experiment is to observe the situation of K kinds of different products in M kinds of non-related parallel machines in different modes of traditional and instant delivery. Analyze the entire process of the workpiece in the simulation system, find out the best route from each node to another node, using system internal Simtalk syntactic to write out workpiece’s assignment method to solve it. The production system is a complex integrated system with many factors affecting the system, but the problems existing in the process can be solved by system simulation. The purpose of this study is to enable the workpiece to be transmitted efficiently to each machine and to calculate the optimal production path. The performance indicators discussed are - total completion Time (MakeSpan) and Mean flow Time, and compare the difference between the fixed transfer mode of traditional factories and the real-time transmission mode of industry 4.0.
