Abstract

The invention discloses a prevention and maintenance associated scheduling optimization method of a large-batch customization production system. The method includes the steps that prevention and maintenance time interval output by an equipment layer is obtained in real time according to a random production plan issued by a market orientation order; delay of balance scheduling is adopted in advance for a system layer, a production conversion opportunity is dynamically used, and cost balance prioritization is carried out in real time; the prevention and maintenance work lead cost balance and work delay cost balance are calculated and compared, so that a maintenance dual-pendulum optimization decision is made; the combination prevention and maintenance result of the system layer is fed back to the equipment layer, a maintenance decision of a next cycle is planned, and a real-time, effective, economical and feasible associated optimization decision-making plan is dynamically and circularly provided. According to the prevention and maintenance associated scheduling optimization method of the large-batch customization production system, through balance maximization of the overall system maintenance cost, prominent economic benefits are brought to the large-batch customization production system of modern manufacturing enterprises.

Description

technical field [0001] The invention relates to a planning method in the technical field of production planning and maintenance decision-making, in particular to a preventive maintenance collaborative scheduling optimization method for a mass customization production system. Background technique [0002] With the increasingly fierce market competition, mass customization has been widely used as an advanced production mode in the transformation and development of today's manufacturing industry. The mass customization production system is configured by multiple equipment of different types according to the diverse batch product process, supporting enterprises to adapt to new market and social needs. Aiming at this kind of production system, research on production and maintenance collaborative decision-making is carried out, and a stochastic production-driven preventive maintenance dynamic scheduling optimization method is proposed, which can ensure the quality stability of mas...
