The Research And Application Of Tanggang Group Production Scheduling System

The market competition in steel enterprises becomes severer. The production shows the tendency of many types and small batch. For the need of production diversification and enhance quality and shorten delivery time, many steel enterprises is pushing enterprise information construct to improve inner produce and manage.Production plan and scheduling system is the core of steel enterprise manufacturing execution system, which is the important part of whole colligation autoimmunization integrated system. The reach indicates that it straightly connected with steel enterprises output efficiency and product cost. It also indicates plan effectively and scheduling arithmetic can heighten furthest enterprise benefit. The main task of CIMS is to establish produce plan and to arrange enterprises production and to handle all kind of abnormity sense in the process of production. It ensures every department with the other to run highness.Aiming at production scheduling system, some researches on the production scheduling system of Tanggang group are made in the thesis as follows:1) This Paper has analyzed steel enterprise C1MS system framework and pointed integration relationships between production scheduling manage system and the other systems on the base of scheduling theory research.2) Based on research of production flow and production characteristics of Tanggang group, the system model of integrated production scheduling in steel enterprise is presented, at the same time, how to make master planning, material requirements planning, production ability balance and scheduling in the system model is analyzed detailed.3) To realize integrated production scheduling, a rule-based grading scheduling model and its algorithm are proposed.To make the production of enterprise run in phase and run effectively, the enterprise needs an exact, effective, timely production scheduling. The production scheduling system aimed at steel enterprise is an important part of CIMS of steel enterprise, which is a bridge between upper management and lower production. The production scheduling system presented in the thesis realizes the global optimization of planning and scheduling to arrive at the goal of shortening the product cycle, quickening the capital circulation, reducing cost and obtaining optimal economic benefits.
