Weight Modification Method for Performance Evaluation Model of Computing System Based on Bayes' Theorem
Daliang Fang, Yuqing Lan · 2018
The definition of a computing system in this paper refers to an integrated system that includes hardware of common computer equipment (servers, personal computers) and operating systems. With the continuous development of the domestic basic hardware and software, the performance evaluation of computing system can provide important basis for decision during its development. This paper explores a weight modification method, which aims to modify the weight of the computational system performance evaluation model that is constructed with the analytic hierarchy process. After establishing the performance evaluation model of the computing system, the model weight is regarded as the probability by the mathematical approximation, and a weight modification algorithm is proposed based on Bayes' theorem. The weight modification algorithm is analyzed, the recommended range of the relevant parameters is figured out, and the weight of the modification is elicited.
