Embodiment 1

[0045] Such as figure 1 As shown, it is a framework diagram of a specific embodiment of a method for evaluating service trustworthy attributes oriented to the manufacturing Internet of Things in the present invention. see figure 1 According to the present invention, the specific steps of a method for evaluating service trustworthy attributes oriented to the manufacturing Internet of Things include:

[0046] S101. Establish a trusted attribute set according to user requirements; trusted attributes include but not limited to credibility, usability, reliability, confidentiality, integrity, real-time, maintainability and survivability. Order M A Represents the set of credible attributes, then M A ={TA 1 , TA 2 ,...,TA n}, where TA i Indicates a credible attribute, 1≤i≤n.

[0047] S102. Define the attribute measurement method, solve the credible attribute weight distribution to obtain the attribute weight distribution set; let W A Indicates the attribute weight assignment ...

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
