Abstract: This paper deals with the evaluation and decision making on advanced manufacturing modes based on the object-based knowledge mesh (OKM) and user satisfaction. Firstly, the fuzzy function-satisfaction degree relationships of the users’ requirements for the OKM functions are defined, and so are the multiple fuzzy function-satisfaction degrees of the relationships. Secondly, operations on both fuzzy and multiple fuzzy function-satisfaction degrees are proposed and clarified. Then, the evaluation on advanced manufactruing modes based on OKM is given. And finally, the evaluation and decision making methods are illustrated by an example to show the validity of the proposed method.

Abstract: This paper deals with a new approach to formal reconfiguration of enterprise information system (EIS) flow based on object-based knowledge meshes (OKM) and binary tree. Firstly, information system flow and its corresponding OKM form are discussed. Then the relations between knowledge points are defined, and the approach to structure expression of OKM is proposed, by which the EIS flows can be formally represented. And then, based on the formal representation, EIS flows can be reconfigured according to mapping rules between practical flow and structure expression of OKM. Finally, an order management flow in an EIS is taken as an example to show the feasibility and effectiveness of the approach.

Abstract: To optimize the structure of enterprise information systems, this paper deals with a new approach to optimize the structure of object-based knowledge mesh (OKM) based on time performance, which is the formal representation of enterprise information systems. Firstly, the relationships between knowledge points are discussed, and time performance of knowledge point relationships is discussed. Then, the representation of knowledge point construction based on the binary tree is proposed, which solves the coding problem of optimization. And then, based on the improved immune genetic algorithm, the structure of OKM is optimized. Finally, the new approach is exemplified and verified, and the optimized the structure of OKM is obtained, which lays the foundation for performance optimization of enterprise information systems.

Abstract: This paper deals with an approach to the approximation measurement on the enterprise information system (EIS) based on its formal representation. To explore the approximation between modules in EISs and lay foundation for the reconfiguration of EIS, an approximation measurement on the object-based knowledge mesh (OKM) and information transfer relationship mesh (ITRM) corresponding to EIS is proposed. Firstly, based on the definitions of the approximation on atom knowledge point (KP) and relationships, the approximation measurement on OKM with only atom KPs is proposed. Then, the approximation measurement on ITRM is also given, with the steps of the approximation measurement on EIS presented in detail as well. Finally, based upon the above, the approximation measurement on EISs is illustrated by an example to show the application of the proposed method.
