Embodiment Construction

[0109] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0110] The cloud manufacturing service evaluation and matching method based on the trust model in this embodiment includes the following steps:

[0111] Step 1: Use the historical service process monitoring data and service result evaluation data in the cloud service resource pool to build a service satisfaction evaluation index system, quantify service satisfaction, and obtain each historical service satisfaction evaluation information.

[0112] Specifically, service satisfaction evaluation indicators include direct indicators that directly reflect the service level of cooperative enterprises and indirect indicators that indirectly reflect the service level of cooperative enterpri...

Abstract

The invention discloses a trust model-based cloud manufacturing service evaluation and matching method. A trust model-based service combination evaluation method for a cloud manufacturing environmentis proposed, so that the matching between service demands and service resources is realized; a cloud manufacturing service combination sequence is constructed, and a matching degree is quantized by using a service comprehensive trust value, so that the problem of incapability of actually fitting real cloud manufacturing service matching in an existing service evaluation method is solved; a mutualevaluation mechanism is introduced for improving the reliability of a trust relationship of both service parties, the trust relationship of the both service parties in a long-term interactive processis represented with a service satisfaction timeliness function to improve the decision-making timeliness of a cloud platform, and a service satisfaction fluctuation evaluation index also improves thestability and flexibility of the platform; and an improved matrix real-coded genetic evolution algorithm is proposed, a penalty function is introduced for correcting a target function of a fitness value, and evaluation and optimization are performed in combination with policies of a roulette wheel selection method and a local tournament selection method, so that the reliability of cloud manufacturing service combination matching is enhanced.

Description

technical field [0001] The invention belongs to the technical field of cloud manufacturing, in particular to a method for evaluating and matching cloud manufacturing services based on a trust model. Background technique [0002] With the rapid development of information technology, networked manufacturing models represented by application service providers, manufacturing grids, agile manufacturing, and global manufacturing have become increasingly important for manufacturing companies to cope with the knowledge economy, globalize manufacturing, and quickly respond to market demand. A kind of advanced manufacturing mode that improves the competitiveness of enterprises and other goals. Although networked manufacturing has achieved certain results in the fields of resource service modeling and packaging, resource allocation and scheduling, collaborative design, workflow management, etc., it still lacks a perfect operation service model in terms of technology and operation mode....
