2、st few years, attention in the manufacturing cycle has shifted towards concurrent engineering (CE). With this, the integration of the different product life cycle processes has become a focus in both research and industry. However, it is obvious that the integration of all manufacturing processes, t

3、aking into account all life cycle aspects from initial functional requirements to final disposal, is hardly feasible in the traditional way.In this paper, the execution of the manufacturing cycle based on information management is explained by describing the development of a generic architecture for

5、 advocated that the sheer integration of manufacturing processes within the product life cycle is insufcient to achieve true integrated product development. For this purpose, the main focus should be on the information that is applied and generated in these manufacturing processes. If the informatio

6、n of the separate processes can be made available during the entire development cycle, it can be the basis for the control of the entire manufacturing cycle. In order to take full advantage of the modied role of information in the product development cycle, a different attitude with respect to the m

7、anufacturing processes is required.One of the main differences is, that the phases in the manufacturing process become instrumental to the information required in the manufacturing process. This immediately implies that processes in the manufacturing cycle haveto be defined as generic as much as pos

8、sible. For example, it becomes practicable to interchange systems developed for different product types (prismatic, sheet metal, etc.). Moreover,if the interfaces of the mutual systems can be defined adequately, these systems can become independent modules,that are able to perform their tasks withou

Information management2.1. Manufacturing engineering reference modelIn order to be able to deal with differe

10、nt views on a manufacturing system, the system is introduced by means of a reference model. A reference model represents a system as an organisation in terms of its structure of relatively independent,interacting components, and in terms of the globally defined tasks of these components 2. The manuf

11、acturing engineering reference model proposed in the present context is shown in Fig. 1.This manufacturing engineering reference model is based on the manufacturing planning & control reference model introduced by Arentsen 1. However, adaptations have been made, in order to emphasize the equivalent

12、importance of products, orders and resources in the entire manufacturingcycle 4.Company management is concerned with the control of customer orders. It is responsible for the strategic decisions concerning the range of products which will be produced and the processes and resources which are require

14、ineering addresses those activities that relate a customer order to a specific (variant of a) product. It is the task of order engineering to compose production orders and to decide when given batches of products must be processed and with which resources. The objective of order engineering is the i

It therefore includes the specification, design,development, acquisition, preparation, use and maintenance of the resources of

16、a company.Production is concerned with the actual execution of the plans generated by the engineering tasks. From production,information is fed back to these engineering tasks.In the manufacturing engineering reference model, information management is discerned as the kernel. This illustrates the opinion that the availability and accessibility of information is preferred over sheer data exchange.2.2. Information managementIn recogni
