Formula 1 is the profit optimal mathematical model, and formula 2 is the mathematical model that is tied of formula 1;

In the formula:

The i----product labelling, i=1,2 ..., n, note: i ∈ N;

J----production equipment mark, j=1,2 ..., m, note: j ∈ M;

y _i--the quantity of-plan converted products i, decision content;

C _i--the contribution coefficient of-product i;

T _Ij---unit product i takies the time of equipment j;

β _j---equipment j normal available process time;

d _iThe market demand of----product i;

l _iThe lowest manufactured amount of----product i is more than or equal to 0;

Z ⁺---nonnegative integer;

6) set up the corresponding relation between the data through the solving result of mathematical model;

7) utilize the optimized application software of mathematical model manufacturing articles order.

The data correspondence table of output products order after the execution of said optimized application software.

This method is theoretical based on TOC; In conjunction with the develop computer software technology; Iron and steel enterprise's production procedure is analyzed and data processing, is mathematical tool with the Nonlinear Programming Theory, in conjunction with advanced develop computer software technology; Set up the smelter Model Optimizing Production Structure, for the optimization of enterprises product structure, formulate the marketing strategy, provide management emphasis and sensitivity analysis etc. that strong help is provided.

The invention has the beneficial effects as follows: the present invention utilizes the product structure optimization mathematical model that the production line of enterprise is optimized, and can find each production line production capacity and the highest product mix of profit, also for sales department carries out the market development parameter is provided simultaneously.The present invention has combined market information that production and operation overall plannings such as resource planning, power balance plan, product structure, economic benefit and rich data resource extremely are provided; Its degree of depth, fineness, range are that the plan of manual establishment is incomparable; Also working out plan by hand can't accomplish; Provide reduce cost, cut the waste, optimize allocation of resources, plans such as optimize product structure, can create remarkable economic efficiency for enterprise.
