Abstract

The invention provides an optimal troubleshooting method based on comprehensive cost, which comprises the following steps of: comprehensively considering factors, such as detection cost, fault probability and the like; calculating a troubleshooting detection sequence; summing detection costs of all points to obtain a total detection cost; respectively multiplying the fault probability of each fault and the total detection cost, and then summing to serve as a comprehensive cost which corresponds to the fault phenomenon under the fault diagnosis scheme; and comparing the comprehensive cost corresponding to different schemes to select the scheme with the minimum comprehensive cost as an optimal troubleshooting scheme. In the optimal troubleshooting method, the detection cost and the fault probability are comprehensively considered, and therefore the optimal troubleshooting method is practical, is suitable for the situation that the total troubleshooting cost of a great quantity of products is considered to be lowered, such as the daily troubleshooting of a large quantity of products produced on the batch in factories, and has a strong application prospect.
