Research On Key Technology Of The Networked Manufacturing System For Deyang Outfit Industry

Outfit manufacturing supplies various kinds of outfit to industries. It is absolutely necessary for industrializing, and provides a foundation to integration national power. Its level is an important mark of international competition power, and a key factor which affects the status of a country in globosity economy. At the present time, China being growing from big to strong in manufacturing, it is necessary to advance the level and enlarge the capacity of outfit manufacturing. Actualizing networked manufacturing is one of ways for improving outfit manufacturing rapidly, and can strengthen sharing knowledge and equipment, promoting cooperation among enterprises. Networked manufacturing for outfit manufacturing is unusual because of its features, such as long industry chain, little batch process, high level technology, long time of process, centralizing industry enterprises, etc. Deyang is one of two bases of heavy-duty outfit manufacturing in China. It is not only an important part of the manufacturing, but also is a representative of outfit manufacturing region. The study on the networked manufacturing system for Deyang outfit manufacturing is carried out in the thesis, which is involved with organization frame, application system, the way for choosing collaborator and constituting virtual enterprise and process modeling. The main results obtained are as follows:1) The organization frame of the networked manufacturing for Deyang outfit manufacturing is proposed, based industrial cluster theory. The conception and predominance of industrial cluster, frame and features of outfit manufacturing are expounded. After the development procedure of Deyang outfit manufacturing being analyzed, it is concluded that regional networked manufacturing is suitable to Deyang. The organization frame of networked manufacturing for Deyang outfit manufacturing is proposed based on industrial cluster organization frame; the status and duty are determined for core enterprises, supporting role ones, government and service units.2) The scheme design of the networked manufacturing system for Deyang outfit manufacturing is accomplished. The system function is identified which includes not only sharing resource, managing and adjusting process, collaborative designing and producing, and electric commerce etc., but also others aiming at outfit manufacturing features, such as managing especial equipments, choosing collaborator accord to custom appraising standard form. The operation style is proposed for the system by which local government provides a platform and enterprises attend. The system running frame, based ASP (application service provider), is introduced and the many aspects for the frame are discussed.3) The system to choose collaborators is designed aimed at the feature of little batch process in outfit manufacturing. The process to constitute virtual enterprise (VE), principia and means are expounded and a system of the appraisement standard for the collaborators is brought forward. The AHP arithmetic to choose the collaborator is presented. At last, the realization of the system to choose the collaborators for the outfit manufacturing system is carried out.4) Three-dimension modeling system for VE is proposed, and the organization modeling system and VE process modeling are designed. Based on analyzing the enterprise modeling theory, according to VE features, a modeling system is presented, which is composed by view dimension, lifecycle dimension and organization dimension. VE organization frame is made up by the elements including VE, item grouper and enterprise. Two methods for the process modeling based IDEF3 and Petri net are proposed. Process overseeing and controlling rule are presented based on project management theory.5) The prototype system for the networked manufacturing for Deyang outfit manufacturing to show the function is programmed. SOA (Service-Oriented Architecture) is taken as the system flame, Windows XP as the operating system, JSP as program language, SOL Server2000 as the database. The part function is put into practice to illustrate the results obtained.
