Method, device and equipment for measuring and calculating repair cost of power transmission project and storage medium

Abstract

The invention discloses a power transmission project repair cost measuring and calculating method, device and equipment and a storage medium, which are used for solving the technical problem of low accuracy of an existing cost measuring and calculating method. The method comprises the following steps: collecting historical maintenance budget data of a preset power transmission project; generating a feature vector according to the historical maintenance budget data; generating a training sample based on the feature vector, and constructing an extreme learning machine (ELM) neural network prediction model based on the training sample; obtaining an initial parameter of the ELM neural network prediction model, and optimizing the initial parameter by using a particle swarm optimization (PSO) to obtain an optimized parameter; replacing the initial parameters with the optimized parameters to obtain an optimized ELM neural network prediction model; training and optimizing the ELM neural network prediction model by adopting the training sample to obtain a trained prediction model; extracting maintenance budget data from the power transmission project; and inputting the maintenance budget data into the trained prediction model to obtain the repair cost.

Description

technical field [0001] The present invention relates to the technical field of cost calculation, and in particular to a method, device, equipment and storage medium for calculating repair cost of power transmission projects. Background technique [0002] For power grid companies, from the perspective of economic operation, the company needs scientific management, integration of resources, effective use, and low cost to create maximum project benefits, to eliminate low-efficiency operations; from the perspective of security and stability, the company needs scientific management , to ensure the safety of equipment in production projects, and to support the company's stable operation. [0003] The existing routine repair standard cost calculation of power transmission production is highly subjective and has low accuracy. The calculation methods used include simple moving average method, weighted moving average method and improved weighted moving average method. However, the mo...
