Mixed integer programming-based metering device production plan optimization method

Abstract

The invention discloses a mixed integer programming-based metering device production plan optimization method and belongs to the metering production plan management field. According to the method of the invention, metering production business processes and whole-life cycle management requirements are sorted through; factors such as demand prediction, material supply cycles, central safety stock, alternate work systems, equipment verification ability and maintenance plans, and transportation are fully considered; a mixed integer programming-based metering production plan optimization model is established; with minimizing cost and stock as an objective, the yalimp toolbox is used to obtain a solution with monthly goods arrival plans, verification plans and distribution plans adopted as decision-making variables; and the solution is fed back and corrected timely according to plan execution conditions and emergency situations. With the method adopted, the defects of personal experience can be effectively avoided, scientific development and efficient implementation of an entire metering production plan can be realized; meter utilization requirements of power supply units and their stations (secondary branch warehouses and direct distribution warehouses) can be satisfied; central stock and production costs can be substantially reduced; and strong support can be provided for the realization of intelligent operation of a metering center.

Description

technical field [0001] The invention belongs to the technical field of metering production, relates to the field of production plan management, in particular to a method for optimizing the production plan of metering devices based on mixed integer programming. Background technique [0002] As a typical achievement and demonstration of the construction of the "big marketing" measurement system of State Grid Corporation, the provincial measurement center is responsible for the arrival, verification and distribution of millions of measurement equipment in the province every year. The production plan is heavy and intertwined. The traditional The measurement production plan is mainly arranged by manual experience, which has the disadvantages of high inventory, low turnover rate, poor timeliness, difficult interaction, and poor flexibility. The optimization method of metering production plan based on factors such as demand priority and other factors, scientifically and rationally ...

[0002] As a typical achievement and demonstration of the construction of the "big marketing" measurement system of State Grid Corporation, the provincial measurement center is responsible for the arrival, verification and distribution of millions of measurement equipment in the province every year. The production plan is heavy and intertwined. The traditional The measurement production plan is mainly arranged by manual experience, which has the disadvantages of high inventory, low turnover rate, poor timeliness, difficult interaction, and poor flexibility. The optimization method of metering production plan based on factors such as demand priority and other factors, scientifically and rationally formulate the arrival, verification and distribution plan of metering devices, which can greatly reduce central inventory and production costs, and improve the response efficiency and service ability of power supply enterprises to meter demand. of great significance
