Currently, in order to ensure the required fault-proof level of technological processes in agricultural production, the following strategies among the main ones: afterfailure, planned systematic and a mixed electrical equipment maintenance and repair strategy. The pervasion of information technology in this segment was not widespread. Application of information technologies in conjunction with implementation of risk-oriented strategy is one of the promising directions of electrical equipment maintenance optimization, yet requires adaptation to sectoral characteristics of agricultural production. The article describes the problem of determining the optimal conditions for adjusting the frequency of maintenance and repair of electrical equipment on the basis of risk-oriented approach. To solve this problem, the equation of annual costs for maintenance and repair of electrical equipment was drawn up taking into account the parameter of its failure risk. The relationship between the change of relative risk and the service frequency was established; based on it, the ranges of frequency adjustment of maintenance and ongoing repair were determined.

The construction of specialty characteristics shall start from the overall characteristics of the school, take the specialty group as the perspective, find the characteristic construction direction in the whole industrial chain, and improve the connotation of specialty. To promote the development of the specialty of mechanical and electrical equipment maintenance and management in domestic polytechnics, taking the construction process of this specialty in Guangzhou Railway polytechnic as an example, it was discussed on why and how to carry out the construction of major characteristics with the main line of the equipment maintenance of rail transit stations and train vehicle repair plants. Aspects were discussed including the establishment of curriculum system, the construction of specialty teachers’ team, the construction of teaching software and hardware resources and the monitoring of teaching quality. The results can be used for reference in the construction of similar specialties in China.

Critical Chain

The critical chain project management theory(CCPM) combining the critical chain technology and resource-constrained project scheduling problem (RCPSP) is an important innovation of project control methods, and it’s widely used to optimize the project duration recently. In this paper the theory presented is applied to the maintenance period arrangements of power plant electrical equipment, and a mathematical model of optimizing the maintenance period is established. Then an improved heuristic algorithm is designed and used to establish equipment maintenance precedence network. On this basis, a new identification method of maintenance network based on critical chain is proposed. Finally, it’s verified with a numerical example that the method proposed can effectively shorten the maintenance period of power plant electrical equipment.
