Study On Production Scheduling On Inventory Control For Cold-rolling Inline And Its Implementation

Cold-rolling sheet production is an industry with high added value. Its production processes, however, are complicated, which have some characteristics, such as multi-unit, multi-process, multi-processes and parallel. And then, it is very difficult to control the inventory. The scheduling in Cold-rolling is an important part of Cold-rolling sheet production, which affects the stop accounts of the machines and the balance of Cold-rolling sheet production process. Therefore, reducing the stop accounts of every machine through implementing the product scheduling of controlling the inventory to improve the whole production efficiency is an important way of improving the whole profit of enterprise.Taking into account the real situation of the process flow in BaoSteel, the inventory control scheduling problem of Cold-rolling production line is studied in this paper. A class of inventory control Scheduling model is established considering unit shutdown cost to reduce the stop accounts which is not planned, and designs a corresponding algorithm which is used to solve the model, then a simulated annealing-based tabu search algorithm which combines the rapidity of Tabu Search Algorithm and the optimization capability of Simulated Annealing Algorithm is proposed to optimize the result. This provides a good solve method which is used to search the optimum result of the inventory control scheduling in limited time. The simulation with real production data shows that the model and algorithm proposed in this paper are feasible.A Cold-rolling production scheduling based on the controlling inventory system which based on the built model and algorithm is developed in this paper. The code is developed by C#, running on the.NET plat. It is based on a SQL Server database. The paper introduces the designed for software system and database system of the Cold-rolling production scheduling and show the function of every module. It can provide effective solutions for the inventory control scheduling of cold-rolling production line, guiding the Cold-rolling sheet production scheduling more effectively. It reaches the effects of reducing unit shut-down times, decreasing the production cost, increasing the production efficiency and reducing the working complexity of scheduling worker.
