Using Data Mining Methods for Predicting Sequential Maintenance Activities

A data mining approach is integrated in this work for predictive sequential maintenance along with information on spare parts based on the history of the maintenance data. For most practical problems, the simple failure of one part of a given piece of equipment induces the subsequent failure of the other parts of said equipment. For example, it is frequently observed in mining industries that, like many other industries, the maintenance of conventional equipment is carried out in sequence. Besides, depending on the state of parts of the equipment, many parts can be consumed and replaced. Consequently, with a group of spare parts consumed sequentially in various maintenance activities, it is possible to discover sequential maintenance activities. From maintenance data with predefined support or threshold values and spare parts information, this work determines the sequential patterns of maintenance activities. The proposed method predicts the occurrence of the next maintenance activity with information on the consumed spare parts. An industrial real case study is presented in this paper and it is well-noticed that our experimental results shed new light on the maintenance prediction using data mining.

Analysis of the Electrically Driven Compressor for New Energy Vehicles

The new energy electric bus has already been used for many years; however, it is also not strange that there are problems in the actual operation process. Base on the running status of new energy vehicles during the early stage, this article provides some opinions on problems of using electrically driven compressor, which is mainly stated oil carryover and vibration noise of several kinds of electrically driven compressor and enumerated the partial performance of the compressors. After all, the behavior of compressor will not only directly affect the braking safety performance, but also had a greater influence on the Sequential maintenance costs.
