Problems solved by technology

However, when computers are used to process optimal services in a service composition environment, and when performing system service calculations, the determination of service dependence is subjective, and it is still necessary for users to input or select according to subjective judgments in certain specific steps. Therefore, how to establish relatively objective criteria for judgment on this basis is also a problem in service selection

Embodiment 1

[0032] Such as figure 1 As shown, the present invention discloses a service selection method based on quality dependence in a service composition environment. After storing the business logic description data in the computer memory, the following steps are included after starting the program operation: Step 1, the CPU reads and stores Business logic description in the business process of the computer memory; step 2, analyze the business logic description to obtain each business role; step 3, analyze the "service-served" relationship between business roles, and determine the relationship between the served party and the service provider Quality requirements, establish the quality judgment dependencies between business roles; Step 4, build a quality dependency graph based on the established quality judgment dependencies; Step 5, use topology sorting to analyze the quality dependency graph to obtain the basis for analyzing each business role Quality judgment rules; step 6, for ea...

Embodiment 2

[0065] The basic starting point of the candidate service selection method based on quality dependency in the service composition environment is to analyze the business logic description, establish the dependency description file for the business roles participating in the business process, and build a quality dependency graph based on the description file established by automatic analysis; The topological traversal of the quality dependence graph is carried out to obtain the quality judgment rules and judgment order. Then the AHP method is used to select candidate services.

[0066] The specific embodiment of the method of the present invention is introduced by taking the following business logic selection process as an example.

[0067] A manufacturer (Manufacture) hopes to find a suitable raw material supplier (Supplier) to provide the raw materials needed for its production through the service selection mode. as attached figure 2 As shown, through the service registratio...

Abstract

The invention discloses a service selection method based on quality dependency relationship under service combination condition. The method comprises storing service logic description data into computer memory and the following steps: reading the service logic description in service procedure stored in the computer memory to get every service role by CPU; analyzing the relations between the service roles, conforming quality demand, and establishing quality judging dependency relation; creating a quality dependency diagram and the quality judging rules for analyzing every service role; selecting quality judging side; deciding the order to execute the service role selection; creating paired comparison matrixes; calculating the satisfaction degree of every service role candidate to the quality demand given by the quality judging side; and selecting a right candidate by the CPU. The whole selection process from establishing the service description in the method is implemented by computer automatically, thus, the objectivity and efficiency are improved.

Description

technical field [0001] The invention relates to a method for selecting candidate services with the best quality in a service composition environment, and is especially suitable for service selection based on quality dependence in a service composition environment that participates in the implementation of business processes in a business logic description on a large-scale computer network business platform method. Background technique [0002] In the service composition environment, different logically described services and organizations exchange information and resources with each other to achieve a certain business goal. When executing this business logic, it is necessary to instantiate logical services and organizations—select the most suitable one from the services and organizations that can provide the same candidates as the requirements to participate in the execution of the business logic. At present, in the methods of service and organization selection based on qua...
