6、In order to respond to the change effectively,manufacturing strategy has to be modified from time to time in accordance with the market situation and customer demand. Any change of strategy should enable manufacturers to be better equipped themselves,with capabilities to cope with demands suchas a f

In order to meet the demand ofrapid product development, various new technologiessuch as reverse engineering （RE）, rapid prototyping （RP）, and rapid tooling （RT） have emerged and areregarded as enabling tools with abilities to shorten theproduct development and manufactu

10、ring time. Forexample, it has been claimed that RP can cut newproduct development costs by up to 70% and the timeto market by 90% 3. However, these equipments aretoo expensive for the small and medium sized enterprises（SMEs）, and many techniques such as 3D CADsolid modelling, RP process planning, fr

Therefore, it is especially difficultfor the SMEs to take full advantage of these technologiesin the product development process. In order tooffer the support of rapid product development fornumerousSMEs,manyRPservi

12、ce bureaus （SBs）whichcan not only manufacture physical prototype and rapidtooling but also provide other engineering services,have been established. By 2001, there are more than500 SBs all over the world. But not every SB canpossess all design and manufacturing capabilitiesrequired, it must employ e

Namely,a virtual enterprise which usually defined as a temporaryalliance of enterprises that come together to sharetheir skills, core competencies, and resource in order tobetter respond to business opportunities, whose cooperati

Every SBconducts only the tasks of its corecompetencies, and depends on numerous partners tocarry out the remaining tasks that this SB has no such manufacturing capabilities to accomplish in time.While a new thought emphasizing service quality

Teleservice engineering is an emerging fieldwhichaddresses service issue for manufacturers and customers. As digital manufacturing technique progresses quickly, digital service will be int

The internet, incorporating computers and multimedia, has provided tremendous potential for remote integration and collaboration in business and manufacturing applications. In order to provide a production collaborative environme
