Metallurgical industry integrative plan scheduling system and method

Abstract

The invention discloses an integrated project program system and the method in the metallurgical industry, which comprises the following steps: the first step: dividing the original integrated project optimization problem into a plurality of son problems; the second step: establishing the linear programming model and solving a son problem; the third step: deducting the energy and the material resource occupied by the son problem in the second step and rebuilding the linear programming model and solving the next son problem until all the problems are solved; the fourth step: getting the integrated project result by synthesizing every son problem result. The invention enhances the program integration.

Description

technical field [0001] The invention relates to a planning and scheduling system and method, in particular to a comprehensive planning and scheduling system and method in the metallurgical industry. Background technique [0002] Comprehensive planning is an advanced production plan based on advanced demand and production capacity, which can be used to guide various departments to balance resources and respond to orders. The comprehensive planning system needs to consider unit capacity, material supply, product process route, safety stock, maximum inventory limit, and other constraints, and generate a plan that includes production planning, resource planning, inventory planning, and Optimized comprehensive plan including benefit plan. [0003] Since the processing objects are discrete in the comprehensive planning, it is more complicated to realize the multi-objective optimization under the premise of many constraints of the process regulations. The existing comprehensive p...

AI Technical Summary

Problems solved by technology

The existing comprehensive planning and scheduling system and method are based on the production-based sales model, which cannot quickly respond to customer needs; 2. The bottleneck information in each production line plan changes every month, resulting in inaccurate production forecasts , the production plan cannot achieve a real balance, and the existing comprehensive planning and scheduling system cannot take this into consideration; 3, the logistics demand between the upper and lower processes in the existing scheduling system cannot be clearly defined, which affects the balance of the production capacity plan; 4, The hourly output in the plan is obtained based on historical experience, and the division of levels is not accurate, so that the comprehensive plan cannot make production plans and resource plans at a finer level such as product specifications and brands; 5. Each quarterly, monthly and weekly plan is made by It is formulated by different people, and the parameter settings of each plan are inconsistent, and the interrelationship between several plans is not close; 6. The planning units are not unified in each plan and system, which makes each plan disconnected

It is difficult to obtain an overall optimization result for the above problems
