Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] The invention mainly includes a method for constructing a cloud manufacturing-oriented service combination path. For the task requirement of the service request proposed by the user, the service request task is decomposed into multiple subtasks, based on the existing abstract services matched by each subtask after the service request is decomposed, and according to the partial order between these abstract services Relationships construct different service composition paths, and then the optimal service composition path can be selected through the evaluation of the combinable correlation degree, so as to realize the construction of service composition paths. For the process, please refer to the attached figure 1 . The specific implementation steps are as follows:

[0022] The first step is to form a partial order relationship between abstract services...

Abstract

The invention relates to a service composition path construction method for cloud manufacturing, in particular to a method for achieving mapping from complicated service request to service combination paths from top to bottom in a cloud manufacturing mode based on driving of user service request. The method comprises the steps of finding partial order relations among abstract services based on combinable association relations among services to achieve aggregation of the abstract services, utilizing the idea of Hasse diagram to build a complete graph of the service combination paths, and selecting the service combination paths by solving the largest combinable degree based on a computing method for combinable degree of the service combination paths. The service composition path construction method for the cloud manufacturing has the advantages of being simple in construction method, strong in applicability and operability and good in expandability.

Description

technical field [0001] The invention relates to a cloud manufacturing-oriented service composition path construction method, that is, a method for generating a complete service composition path graph according to an abstract service set and selecting an optimal service composition path therefrom. The invention belongs to the technical field of distributed manufacturing system information integration. Background technique [0002] Although networked manufacturing has made great progress, there are still some problems in terms of technology and operation mode, such as the lack of centralized management and operation of services, and the lack of a good solution to the dynamic sharing and intelligent allocation of manufacturing resources. In network communication, security in data transmission, etc., these problems have seriously hindered the popularization and application of networked manufacturing. Aiming at the bottleneck problems encountered in the current development and a...
