Equipment maintenance support is a solid reserve for the combat capability of the military,which is related to the life cycle of the entire equipment.With the increase in the degree of information and complexity of equipment,the traditional three-level maintenance support system has been deepened and reformed into a two-level maintenance support system including army-level maintenance and base-level maintenance.Among them,with the use of a large number of new equipment,for baselevel maintenance,the equipment is more complicated,the scope of the maintenance technology involved is wider,and the operation process and resource allocation process are more cumbersome.The rise of technologies such as the Internet,cloud computing,artificial intelligence,are promoting the reform and technological advancement of equipment maintenance support systems.The existing base-level maintenance support program formulation model and process has become increasingly incompatible with it.Therefore,It is of great significance to conduct research on the base-level maintenance support resource scheduling under the new situation.This article takes this as the research goal,based on the role coordination theory,combined with equipment maintenance support theory,by building a maintenance support role coordination model,to achieve the scheduling and optimization of equipment maintenance support resources in the cloud environment.The specific work and results are: First,it introduces the equipment maintenance support theory,cloud environment concept,and equipment maintenance support resource scheduling related concepts and processes;Secondly,for the equipment maintenance support activities under the base-level cloud service model,the E-CARGO model in the role coordination theory is introduced to analyze the role coordination of equipment maintenance support activities.It formalizes actual problems to form a solvable multi-objective optimization mathematical model,and explores how to obtain the multi-objective evaluation matrix;After that,the weight calculation scheme was designed by using the analytic hierarchy process-entropy weight method combining subjective and objective methods to obtain the multi-objective evaluation matrix.At the same time,a resource scheduling algorithm and resource conflict resolution scheme for solving multi-objective optimization are designed based on genetic algorithm and critical path knowledge.Finally,simulation experiments verify the feasibility and rationality of the algorithm.
