Service credibility assessment method oriented to internet of things manufacturing

Abstract

The invention relates to a service credibility assessment method oriented to internet of things manufacturing. The method comprises the steps that a credibility attribute set is built according to user demands; an attribute measuring method is defined, and credibility attribute weight allocation is solved to obtain an attribute weight allocation set; a credibility index tree is built according to the credibility attribute set and the attribute weight allocation set; credibility attributes capable of being directly measured are extracted; credibility evidences are collected from an assessment object over a time period, credibility attributes served at the current time period are assessed according to the credibility evidences and the measuring method of each credibility attribute, and a current assessment result is obtained; the current assessment result is amended by utilization a historical assessment result; derivation is carried out upwards from the bottom layer of the credibility index tree layer by layer according to the amended assessment result to work out a root node value, and the root node value serves as the service credibility attribute value. The internet of things manufacturing software and credibility of interaction of the internet of things manufacturing software are assessed through the built credibility index model, and software service and credibility of interaction of the software service are ensured.

Description

technical field [0001] The present invention relates to the field of manufacturing Internet of Things, and more specifically, to a service credibility evaluation method for manufacturing Internet of Things. Background technique [0002] Manufacturing Internet of Things technology is based on the realization of the Internet, embedded system technology, RFID technology, and sensor networks to build a modern manufacturing Internet of Things network based on middleware, massive information fusion processing and system integration technology, etc., based on Internet of Things network development The service platform and application system solve the problems of comprehensive information perception, reliable transmission, pervasive computing, precise control and credible service in the process of product design, manufacturing and service, improve the added value of product technology, enhance the management and control capabilities of the manufacturing and service process, and promo...
