A Method for Simulation Model Validation Based on Theil’s Inequality Coefficient and Principal Component Analysis
The creditability of simulation model is validated by the classical method of Theil’s inequality coefficient though analyzing the consistency between the simulation output and reference output. The reference output is not treated as the benchmark for comparison in the classical method and the difference of trend between the simulation output and reference output is not considered. For solving the problems, the algorithm of Theil’s inequality coefficient was improved, the models for describing the coincident degrees of position and trend between the simulation output and reference output were given and the simulation model validation method based on principal component analysis was proposed. The rationality and efficiency of the method were validated in the application.
