Abstract

The invention relates to a method for calculating the number of probability-based service providers under a service architecture and the time period, belonging to the technical field of service-oriented architecture SOA. The method is characterized in that a service requester designs a comprehensive performance evaluation index set of all the service providers for detailed performance index values of various services provided by the service providers, and uses a probability distribution function of a performance optimum value among all the arrivers as predetermined reliability according to the comprehensive performance evaluation index set, so as to determine the number of the service providers intended to be waited and the time period intended to be waited. The method analyzes service performances of the services and relations between other types of activities in the services and actual businesses of enterprises from the overall situation of the business process, wherein various detailed performance indexes can be flexibly formulated as required, have strong flexibility, and can be realized on line or off line.

Description

technical field [0001] The invention belongs to the technical field of service-oriented architecture SOA. Background technique [0002] Service-Oriented Architecture (SOA) is changing the traditional system architecture method in a loosely coupled, bottom-up and point-to-point manner. Through the dynamic release, discovery, combination and reuse of a large number of services on the network, it provides a new mechanism for enterprises to dynamically integrate different technologies independent of the system platform, making business optional and IT [0003] Composability is greatly enhanced. Therefore, the performance of Service-Oriented Business Process (SOBP) in a service-oriented environment is closely related to the selection, combination and efficient operation of numerous internal and external IT resources including services. [0004] Therefore, the performance analysis of SOBP under SOA involves a large number of service requesters, service providers and other types ...
