Abstract:

This paper presents a system that uses the Web to link designers and manufacturers to provide fast and accurate cost estimation and supplier selection. The system is a Web-based integrated environment that provides process-planning capabilities, machining time and cost estimation, and supplier selection. By utilizing Web technologies, one customer or designer can submit a request for quotation for its product to a central server that links to various manufacturing suppliers. Then, the server selects appropriate suppliers and helps them generate accurate cost estimation. The central server provides the designer supplier options with cost information and without compromising the manufacturerspsila sensitive cost data. The system is modeled with united modeling language and the prototype software is implemented using Java 2 Enterprise Edition, Java Server Page and Enterprise Java Beans.

I. Introduction

Product development is the result of a team effort involving a multi-disciplinary group of designers, manufacturers, and even suppliers. The design activity, which may account for only 5% of a product's cost but may influence on 70% of the final cost [1]. With fierce global competition over price, quality, and time to market, the ability to find suppliers quickly is crucial for a company in developing new products. This competitive pressure propagates through the entire supply chain, requiring accurate cost estimation and appropriate price from all manufacturers in the supply chain. The ‘bull-whip’ effect [2] exacerbates the situation even more, making suppliers vulnerable to demand and cost variations.
