Method On Parallel Transportation System Credibility Evaluation

ABSTRACT:CredibilityEvaluation is of great significance for development and application of parallel system. Only by guaranteeingthat parallel system has sufficient credibility,can the final result has the value and significance of practical application. But now, in parallel system field, research on reliability is still very few. In this condition, based on the ACP method (artificial systems, computational experiments, parallel execution), this paper proposes a credibility evaluationmethod for parallel system based on interval type-2fuzzy logic system. The evaluation method is a combination ofprediction model and computational experiments. By comparing both of them, this paper establishes a credibility evaluation modelSuccessfully for parallel system.This thesis addressed the following several key problems:This paper describes the idea, Content and structure of parallel transportation systems.From the basic credibility theory, this paper expounds the credibility significance and research methods in the parallel transportation system, summarizes the various methodscredibilityEvaluations which is usually used.This paperestablishesacredibility evaluation method which is a combination of computational experiments andprediction model which is based on interval type-2fuzzy logic theory. The paper also establishesa predictive model of the actual systemby using type-2fuzzy logic theory, and then making comparisonsbetweendata from computational experimental and a prediction Interval which is generated fromprediction model. By the Comparisons, this paper establishes a credibility evaluation model for parallel system.This paper makes computational experiments for the average waiting time which is a key issue in parallel transportation system, andobtainsseveral different experimental results,thenevaluate them by using the predictionInterval of actual system. This paper also tries to adjust the system internal parameters throughthe feedback of error.The results show that it can reduce the error of the calculation results by adjusting system internal parameterscorrectly and appropriately.By this, this paper achievesafeedback control functiontoa certain degree.
