矿物采、选、冶生产系统是一个不满足Leontej投入产出模型的基本假设“每一部门只生产一种产品”的系统。本文在作者提出的不受上述假设限制的推广投入产出模型的基础上,建立了采、选、冶系统利润最优计划模型,编制了通用程序包,利用这组模型,能够制定最优生产计划,进行平衡分析,提供挖潜方案,灵敏度分析和预测,对企业各生产环节进行评价等多种用途。此外,利用挖潜系数能够用模糊数学方法对同类企业进行科学评比,最后给出了一个讨论实例。 The mining, dressing and smelting production system is a system that does not satisfy the basic assumption of the Leontej input-output model that “only one product per department” is produced. Based on the proposed input-output model that is not subject to the above assumptions, this paper establishes a profit-optimal planning model of mining, dressing and smelting systems, and prepares a generic package. With this set of models, we can make the optimal production Plan, balance analysis, provide tapping potential programs, sensitivity analysis and prediction, evaluation of the production of various aspects of the enterprise and other purposes. In addition, the use of scouring potential can be used fuzzy mathematics scientific evaluation of similar enterprises, and finally gives a discussion of examples.
