Description

technical field [0001] The invention relates to a service combination method, in particular to a nonlinear service combination method based on skyline calculation. Background technique [0002] The proposal of service-oriented architecture solves the problem of cross-platform resource sharing. In order to ensure the modularization and reusability of services, a single service generally has a relatively single function. When users use it, they need to combine individual services to meet their complex functional requirements. The emergence of cloud computing has promoted the exponential growth of the number of services. These competing services with similar functions have posed new challenges to the research on existing service composition technologies, making it impossible for users to quickly find services that match their needs. How to quickly obtain a service composition scheme that satisfies functional requirements and has optimal non-functional attributes has always be...
