Reconfigurable products and manufacturing systems have enabled manufacturers to provide "cost effective" variety to the market. In spite of these new technologies, the expense of manufacturing makes it infeasible to supply all the possible variants to the market for some industries. Therefore, the determination of the right number of product variants to offer in the product portfolios becomes an important consideration. The product portfolio planning problem had been independently well studied from marketing and engineering perspectives. However, advantages can be gained from using a concurrent marketing and engineering approach. Concurrent product development strategies specifically for reconfigurable products and manufacturing systems can allow manufacturers to select best product portfolios from marketing, product design and manufacturing perspectives. A methodology for the concurrent design of a product portfolio and assembly system is presented. The objective of the concurrent product portfolio planning and assembly system design problem is to obtain the product variants that will make up the product portfolio such that oversupply of optional modules is minimized and the assembly line efficiency is maximized. Explicit design of the assembly system is obtained during the solution of the problem. It is assumed that the demand for optional modules and the assembly times for these modules are known a priori. A genetic algorithm is used in the solution of the problem. The basic premise of this methodology is that the selected product portfolio has a significant impact on the solution of the assembly line balancing problem. An example is used to validate this hypothesis. The example is then further developed to demonstrate how the methodology can be used to obtain the optimal product portfolio. This approach is intended for use by manufacturers during the early design stages of product family design. 相似文献

Development of Expert System for Concurrent Product Design and Planning for Assembly 总被引:5,自引:3,他引:2

This paper addresses the development of an expert system for concurrent product design and assembly planning (CDAPFAES) including
conceptual design, detailed design, assemblability analysis and design for assembly, assembly system design, assembly process
planning and stimulation, and technical–economics justification. This approach is implemented through an agent-based framework
with concurrent integration of multiple cooperative knowledge sources and software. This intelligent system can offer systematic
assistance for assembly design and planning in the early stage of product development and facilitate, as far as possible,
the use of flexible assembly equipment, including robots. Finally, this new design methodology is illustrated with a successful
implementation of a switch product design. 相似文献
