It is most important to develop a reasonable cost performance index for multi-Objective path planning. Based on Voronoi diagram method for the path planning,this paper studied the synthesis method of the multi-objective cost performance index. According to the application of the cost performance index to the path planning based on Voronoi diagram method,this paper analyzed the cost performance index which had been referred to at present. The analysis show out the insufficiency of the cost performance index at present that it is difficult to synthesize sub-objective functions because of the great disparity of the sub-objective functions. Thus,a new approach was developed to optimize the performance index with the multi-objective fuzzy optimization strategy,and an improved performance index was established,which could coordinate the weight conflict of the sub-objective functions. Finally,according to the example,the validity and rationality of the new performance index has been proved.
