Embodiment Construction

[0015] refer to Figure 1-2 . The specific steps of the weight-based multi-attribute maintenance decision-making method for equipment in the present invention are as follows:

[0016] 1. Determine the specific equipment that requires maintenance decision-making, and list all feasible maintenance solutions.

[0017] Taking "wireless sensor" as the failure mode, there are six maintenance schemes for the goal of maintenance decision-making: minimum maintenance, minimum maintenance priority, imperfect maintenance, imperfect maintenance priority, replacement repair, and replacement repair priority.

[0018] 2. Establish a hierarchical model structure for maintenance decision-making.

[0019] The model of the present invention is divided into total target layer, rule layer and program layer, wherein the total target layer is the goal that maintenance will reach, and the rule layer is each sub-goal and its correlation relationship considered when evaluating each maintenance program...

Abstract

The invention discloses a weight-based equipment multi-attribute maintenance decision-making method, which is used for solving the technical problem of low equipment maintenance efficiency in the existing equipment multi-attribute maintenance decision-making method. The technical solution is to establish a maintenance decision-making hierarchical model structure according to the maintenance conditions and maintenance plan; secondly, analyze the parameters of the maintenance decision-making hierarchical model, and for the equipment to be maintained, give the parameters of each state node and target node according to the maintenance conditions and mutual influence, and quantify the parameters. The influence of the status node on the target node; then construct a judgment matrix from each maintenance condition and the corresponding evaluation index, and obtain the weight vector according to the judgment matrix, and check the judgment matrix to avoid the weight error caused by incompatibility; finally, based on the established maintenance decision-making hierarchy model , driven by the weight, using the obtained judgment matrix and the parameter value of the target node to calculate the benefit value of the corresponding maintenance plan, so as to give the optimal decision. The method effectively addresses multiple decision objectives and decision makers' preferences, and improves maintenance efficiency.

Description

technical field [0001] The invention relates to a decision-making method for equipment multi-attribute maintenance, in particular to a weight-based multi-attribute maintenance decision-making method for equipment. Background technique [0002] The document "Chinese Invention Patent Publication No. CN102623910A" discloses a reliability-based decision-making method for switchgear maintenance. This method analyzes the aging life of the switchgear on the basis of the reliability of the switchgear, and quantifies the importance of the components of the switchgear to be repaired. Evaluation analysis. At the same time, use the reliability data of switchgear, voltage level, importance of faulty components, and grid connection structure to sort and group the equipment to be repaired, and collect the load forecast information of the system where the switchgear is located, taking into account the maintenance capacity constraints and weather constraints. On this basis, the switchgear m...
