Description
Technical field
The invention belongs to metal material processing areas of information technology, and in particular to a kind of smelter whole process unit production capacity
Distribution control method.
Background technology
Set reformation problem during metal material processing is the main contents of metallurgical enterprise production management, production capacity
The quality of distribution is directly connected to stabilization of equipment performance and operational efficiency, the quality of product and the production cost of each unit of factory.
By taking steel mill as an example：Large iron and steel enterprise is often covered to be processed including the multiple tracks serial such as ironmaking, steel-making, hot rolling, cold rolling
Operation, ironmaking are to adopt iron ore powder, coke for primary raw material, ultimately form molten iron through a series of smelting processes；Steel-making is
With molten iron, steel scrap etc. as raw material, by heating the concrete technology deoxidization desulfurations such as fusing, slag making, dephosphorization, oxidation and decarbonization, going remove impurity
Matter produces the smelting process of molten steel, and casting forms slab；Hot rolling be by recrystallization temperature more than rolling, slab is rolled into into steel
Band；It is cold rolling be by recrystallization temperature below rolling, hot rolled strip template is further adjusted, so as to forming properties are excellent
Coil of strip more or steel plate；The operations such as annealing afterwards, zinc-plated, color coating to the internal grain structure of coil of strip, surface texture at
Reason, forms the different steel band of processing characteristics and steel plate.
As above the technique per procedure processes purpose, and processing technique is different, so as to cause production process to production material
Attribute specification is different, and in large iron and steel enterprise, there is feed relation and (be illustrated in figure 1 and enumerate iron and steel between each procedure
Corporate process), the production of each procedure is instructed by single controller, the Production Controller of the different units of different operations without
Communication connection, therefore, in the production process of steel mill, it is impossible at the same consider before and after road unit production stability and product matter
Amount, so as to the overall operation stability and efficiency that cause each unit decline, product quality cannot ensure.With the steel-making in steel mill,
As a example by two units of hot rolling：The safety and stability of STEELMAKING PRODUCTION depends on the same steel grade material of q.s continuously to produce, otherwise, will
The underproof mixed friendship base of composition and the underproof T-shaped base of specification are formed, and when the steel water shortage of identical refining route, it is impossible to
Ensure the normal operation of refine；The stability of hot rolling production need to have enough hot rolling materials and appropriate difficult stocking, cannot such as provide
Enough hot rolling materials, will be unable to by roll band heat, so as to ensure being smoothed out for hot rolling, and a large amount of hardly possible stockings of Continuous maching
The stable operation of hot rolling will be had a strong impact on；For the material of same steel grade, while many including hot rolling material, difficult stocking, ordinary steel etc.
Material is planted, it is series-produced simultaneously in the big quantity set of steel-making unit, hot rolling hot rolling material, the centralizedly supply of difficult stocking certainly will be caused, so as to
Affect the steady production of hot rolling.
At present, in the produce reality of large-scale metallurgical enterprise, the production control of each unit is by the controller list each other without communication
Solely perform, the coordination between each unit mainly balances form by regularly artificial unit Productivity Allocation.As set state is moved
State changes, and the processing constraint per procedure is various, it is considered to material category it is various, enormous amount is artificial to formulate unit production capacity point
The process requirements of multiple units are taken into account simultaneously cannot with control program；At the same time, this method is due to lacking real-time, it is impossible to
Dynamic considers the machining state of each unit, formulates and ensures stable operation of unit, the unit Productivity Allocation control of qualified product
Scheme；In addition, the execution response time for manually formulating form is longer, and the unit of large-scale metallurgical enterprise is continuous operations mostly,
The manual type cannot adapt to the continuous operations pattern of unit.
The content of the invention
For the problem that prior art is present, the present invention provides a kind of smelter whole process unit Productivity Allocation controlling party
Method.
The technical scheme is that：
A kind of smelter whole process unit Productivity Allocation control method, comprises the following steps：
Step 1：The machining path of production status, contract according to each unit of smelter, sets up smelter whole process
Unit Productivity Allocation Controlling model；

The feasible constraint of feed, each unit quantity in stock and life between production and transport ability restriction, each unit between beam, each unit
Relation constraint, unit quantity in stock restriction between yield；
Each unit production capacity restriction：Volume of production of the unit in some time segment limit is less than its production capacity upper limit；
Production and transport ability restriction between each unit：The car loading transported between two units in some time segment limit is not
The upper limit is transported more than which；
The feasible constraint of feed between each unit：In the range of the t periods, unit i is another unit j processing kth kind material
Total amount can be supplied to the material amount usable of k-th species of unit j, i.e. machine before the t periods less than t period unit i
The material of k-th species that group i can be supplied to unit j front storehouses of arrival unit i before the total amount upper limit and t periods of getting the raw materials ready can be supplied to
The kth kind quantity of material sum of unit j, then unit i has been supplied to the total amount of the kth kind material of unit j before deducting the t periods；
Relation constraint between each unit quantity in stock and volume of production, including between final step unit quantity in stock and volume of production
Relation constraint, the relation constraint between non-final step unit quantity in stock and volume of production；Wherein, final step unit quantity in stock
Relation constraint between volume of production：The quantity in stock of final step unit cuts the previous period for its previous period quantity in stock
Demand, along with the previous period is fed to the quantity of material of the unit；Between non-final step unit quantity in stock and volume of production
Relation constraint：It is which plus other units of previous period that non-final step unit quantity in stock is its previous period quantity in stock
The total amount of material of production, then cut the total amount of material that the unit of previous period is other unit productions；
Unit quantity in stock restriction, including the constraint of unit product category quantity in stock lower limit and unit product category quantity in stock
The upper limit is constrained；
