The factors and process in networked manufacturing resources evaluating are given, and the service function and the system architecture of WUXIASP is set up. It is useful to actualize area networked manufacture.

Study on the Manufacturability Evaluation Based on Double-layer Model of Manufacturing Resources

Virtual organization is a new production patter and a principal part in advanced manufacturing systems such as agile manufacturing. Manufacturability evaluation is the necessary condition to form the virtual organization. A new manufacturability evaluation approach is described in this paper, which is carried out based on every process feature under the double-layer model of manufacturing resources proposed by authors. The manufacturing resources that build up the virtual organization are selected according to the results of manufacturability evaluation.

Research on shipbuilding production logistics system combining MRP-Ⅱ with JIT

Shipbuilding production management and logistics control are studied so as to find an advanced shipbuilding production logistics management style.The necessity and feasibility to integrate MRP-Ⅱ(manufacture resource planning)and JIT(just-in-time)are researched properly following the comparison of MRP-Ⅱ and JIT and the analysis of shipbuilding production characteristics.A shipbuilding logistics system combining MRP-Ⅱ with JIT is set up and discussed according to a master production schedule(MPS),MRP and workshop-floor production control.The system is able to simplify the shipbuilding production plan,balance the workshop production,stabilize the supply,and inspire positivity and creativity so as to raise the shipbuilding production management level.

POLICY-MAKING MODELS WW EMBEDDING IN MRP-Ⅱ

Basing on the advanced foreign management theory and methods, introducing MRP-Ⅱ having DSS function and combining Chinese conditions, we present in this paper a method of embedding the block of “lot size” production in MRP-Ⅱ.

The Advanced Manufacture Theory and Practice Based on the Management Science

The paper points out that the science and technology, social productivity and economic form are the decisive strengths in facilitating the reformation of the production method of the manufacturing industry. This kind of strength happens through making an influence on the theory of management and science. It analyses the stage and the characteristic of the development model of manufacturing industry of human society, and on this basis does the detailed research on the several patterns of the advanced manufacturing theory and practice： the computer integrated making, concurrent engineering, lean production, agile manufacturing, planning of enterprise resources, global manufacturing. Finally, it thinks that the development model of the advanced manufacture theory and practice embodies a continuous curve of the technical innovation, which is on the basis of the theory of management science.

Framework for Grid Manufacturing

With the development of networked manufacturing, it is more and more imminent to solve prob-lems caused by inherent limitations of network technology, such as heterogeneity, collaboration collision, and decentralized control. This paper presents a framework for grid manufacturing, which neatly combines grid technology with the infrastructure of advanced manufacturing technology. The paper studies grid-oriented knowledge description and acquisition, and constructs a distributed knowledge grid model. The pa-per also deals with the protocol of node description in collaborative design, and describes a distributed col-laborative design model. The protocol and node technology leads to a collaborative production model for grid manufacturing. The framework for grid manufacturing offers an effective and feasible solution for the problems of networked manufacturing. The grid manufacturing will become an advanced distributed manu-facturing model and promote the development of advanced manufacturing technologies.

A classification matching method for manufacturing resource in cloud manufacturing environment

Cloud manufacturing(CMfg),combining the idea and technologies of cloud computing and Internet of Things,is an emerging service-oriented manufacturing model.The supply–demand matching of manufacturing resources is one of the key technologies for implemention.However,resources in CMfg system are geographically distributed,functional of similar and dynamically changeable,and these features make it difficult to obtain higher accuracy for existing matching methods.In order to select the most satisfied resources in CMfg,a semantics-based supply–demand classification matching method(SDCM)is proposed.Firstly,the implementing framework of SDCM is constructed.Then,combined with the theories of ontology and dynamic description logic,a semantics-based SDCM algorithm is designed,which includes four implementation stages,respectively,basic information matching,IOPE parameters(Input,Outputs,Preconditions,Effects)matching,QoS(Quality of Service)matching and comprehensive matching.Finally,a case verifies the feasibility and effectiveness of the proposed method.
