“…To reach this goal, there are several different approaches to implementing CE and reducing time during CPD. Very often, some kinds of information management systems are generally built around CAD systems to manage the product content and design model information [3]. In addition, some information systems known as PDM systems are often employed to provide information sharing and to facilitate cooperative design.…”

One of the major goals of Concurrent Product Development (CPD) is to shorten the design cycle time by increasing more task overlaps of the ensuing design activities. Increasing task or activity overlap often hinges on two timing questions (a) ''When does the downstream activity require certain information from its upstream activities and (b) when will the required information on an activity be available for scheduling the next dependent task ?'' The paper discusses a constraint-driven execution plan to handle the concurrency during scheduling of various dependent tasks. This constraint-driven execution plan is designed to relieve the alignments of start and end points commonly encountered during scheduling of the concurrent tasks. It is not essential that an activity will start only when a dependent activity is fully finished. In constraint-driven execution plan, a task or an activity can be initiated as soon as the required information is available rather than after the completion of all the upstream activities dependent on it. The paper shows that if we follow this execution plan during a CPD process, concurrencies among the ensuing design activities can be maximized. The paper also discusses how this execution plan can be used in a context of a workflow management system (WfMS). Employing this plan, it is possible to easily transform most of the event-condition-action (ECA) rules-based workflow model -from its activity completion event-driven forms -into an information-constraint-satisfaction-driven forms. This execution plan, thus, enables an event-driven WfMs to support concurrency of tasks during product development and concurrent tasks' scheduling.

The development of the contemporary and advanced manufacturing technology (AMT) is the favorable subsisting and developing environment for traditional manufacturing enterprise. In this paper, the practical requirement to information technology and the key problem to manufacturing information system for the contemporary manufacturing enterprise (CME) in dynamical market environment are analyzed. The developing trend and characteristic of CME is discussed. Also, a software exploiting integrated framework with contemporary manufacturing info system is designed. It is the base that more advancing the networked integrating product development and manufacture, adapting the new product development management and organizing mode for contemporary manufacturing enterprise.

Previous Knowledge-Based Engineering (KBE) systems have difficulty in effectively managing the whole design process which often makes the modeling of product fall into chaos. Processoriented knowledge-based CAD system is proposed in this paper to manage product design process. For realizing process-oriented knowledge-based CAD system, mathematical representations of process design are proposed; the algorithms of process planning using graph theory are studied. A detailed discussion about typical design is put forward including process-oriented knowledge based design methods and architecture. The implementation of Processoriented knowledge based design of reducer is studied as a case. Process-oriented knowledge-based CAD system is realized which makes the whole design process efficient and stable.
