Abstract:

A system was developed to support automobile reliability-evaluation and automobile-enterprise operation-decision based on the automobile warranty data, considering customer’s actual needs. The system framework was established with functions of multi-task management and multi-dimensional analysis; External databases were designed to support data analysis and mining. The system has functions such as automatic data cleaning, failure statistical analysis, reliability evaluation, scientific decision making and data visualization. Combining the actual two-dimensional warranty data from 3 vehicle types, the system was applied to carry out fault statistical analysis, reliability evaluation, and to predict the company’s demand of maintenance spare parts in the next quarter. The results show that the relative error between the predicted value and the actual value is less than 5% when predicting spare parts of automobile enterprise in the next quarter. Therefore, the system can support the product evaluation and automobile-enterprise operational-decision.

Key words: automobile enterprises, reliability evaluation, enterprise operational decision, automobile warranty data, system design
