Concurrent engineering: A compromising approach to develop a feasible and customer-pleasing product.

To develop a customer-pleasing and economically and technically feasible product, it is necessary to utilize the best possible know!edge of the market, the customers, the core product technology, and the cost implications of design alternatives. It requires the concurrent involvement of team members from merchandizing, product development, and purchasing and production-engineering departments of the enterprise. The merchandizing department identifies customer needs however, considering only customers' requirements, without technical information it is not possible to develop a feasible product. Conversely, the function-oriented designers in the product development department determine the subsystems' weight, which are technically feasible but may ignore the qualitative issues desired by the customers. To identity the economic feasibility of the product, the purchasing and production-engineering departments calculate the estimated cost by evaluating the cost implications of the design alternatives. Therefore, to produce an economically and technically feasible product with customer pleasing quality, a trade-off among these three sets of weights is essential. Here, we propose an optimization model that assimilates three sets of weights of the subsystems to a final one. The resultant set of weights will represent the effects of concurrent cooperation among merchandizing. product development, purchasing and production-engineering departments of the enterprise.
