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 device multi-attribute maintenance decision method based on weight and is to solve the technical problem of low device maintenance efficiency caused by a conventional device multi-attribute maintenance decision method. The technical scheme is characterized by establishing a maintenance decision hierarchy model structure according to maintenance conditions and maintenance plans; then, analyzing parameters of the maintenance decision hierarchy model, for a device to be maintained, giving parameters of each state node and target node according to the maintenance conditions and mutual influence and quantifying the influence of the state nodes on the target nodes; constructing a judgment matrix according to the maintenance conditions and corresponding evaluation index, obtaining a weight vector according to the judgment matrix and detecting the judgment matrix to prevent weight errors caused by incompatibility; and finally, based on the established maintenance decision hierarchy model, with the weight being as a drive, and by utilizing the obtained judgment matrix and the parameter values of the target nodes, calculating benefit values corresponding to the maintenance plans, thereby providing an optimal decision. The method effectively solves the problem of influence of a plurality of decision targets and preference of a decision maker on the decision result, 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...
