| Summary: | 碩士 === 國立成功大學 === 工業設計學系碩博士班 === 90 === Hign manufacturing technology and powerful computer software are two important tools for the improvement of product quality and value. With these two useful tools, product designers can overcome lots of critical problem easily. Therefore designers can contribute their efforts to settle more commands from manufacturers and customers.
Concurrent engineering design can be used to avoid separation of each member in a teamwork. If product designers consider problems that might happen in the manufacturing process, the quality of design and product will be promoted. And save the cost in mold manufacturing processes, manufacturing process and assembly process. However, designers seldom consider the assembly problems in their development of a product. In fact, the concept of design for assembly is not newly introduced, but many designers always ignore the problem of assembly process. The assembly process is a combinational optimization problem with the execution of assembly operations and the selection of the assembly sequence of a product. In the assembly operations each operation joins one part of product with another part to form a larger one. The assembly sequence to a product has significant effect on the efficiency of the whole assembly process.
This research focus on the study of assembly sequences in product design procedure. Assembly sequences planning is one field with assembly process. A systematic procedure is needed not only to generate feasible assembly sequences but also to find an optimal sequence to the product. In order to select the most suitable one. However, since there usually exists a large number of feasible sequences, an efficient method to generate assembly sequence is necessary. This research develop assembly sequences assistance procedures to deal with the problem of generating assembly sequences to designers. The applications of the assistance procedures are illustrated using the coffeemaker product. The general approach steps for this research are (1) to develop an easy assembly sequences planner with the assembly rules, (2)to use the computer software in the generation of assembly sequences, and(3)to enhance the computing efficiency by searching for the subassembly. The assembly sequences are then described in a form of hierarchical structure. The results will provide designers with an efficient design procedure without computational complexities.
