Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0048] Different from the existing objective evaluation method, the present invention intends to adopt an objective evaluation method of software service value based on Pareto optimal set. In this evaluation method, firstly, determine the evaluation dimension of the software service and obtain the corresponding dimension data; secondly, obtain the Pareto optimal set based on the concept of Pareto dominance; thirdly, calculate the weight factor of each evaluation dimension in the optimal set based on the coefficient of variation ; Then, normalize all the sample data; finally, calculate the comprehensive score of the software service through the weighted sum model. It is worth noting that in the weight calculation process, ...

Abstract

The invention discloses a method for objectively evaluating a software service value. The method comprises the following steps of: determining an evaluation dimension of a software service and acquiring corresponding dimension data; solving a Pareto optimal set on the basis of a Pareto dominance concept; calculating a weight factor of each evaluation dimension in the Pareto optimal set based on the variable coefficient; normalizing all the sample data; and calculating a comprehensive score of the software service through a weighted sum model. According to the method, human factors are removed,subjective randomness is avoided, and an evaluation result is more objective and accurate; the weight of each evaluation dimension is determined through the optimal sample set, and compared with a mode of using all samples, the method has relatively high robustness.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to an objective evaluation method and device for software service value based on Pareto optimal set. Background technique [0002] In recent years, with the widespread application of cloud computing technology, more and more software services have been deployed on cloud platforms in large numbers. At the same time, many software services with similar functions and different performances (or software service quality) appear in the cloud platform. Therefore, how to objectively and automatically evaluate many similar software services through software, and select software services that meet user needs from among many similar software services has become a problem that cloud platform users have to consider. [0003] Software service value evaluation is the most common method to solve this technical problem. By quantifying the value of each software service, the optimal...
