(一)在科学上,用以模拟和表述客观现象相互关系的数学图式通称为数学模型.它的特点是用数学方式表述事物的数量变化,乃至质量变化,建立数学模型有助于深入探寻客观事物的内在规律.众所周知,工业企业产品成本和利润指标之间存在着密切的关系,即:收入-成本=利润.为了更精确地表述这种关系,建立工业企业产品成本和利润的数学模型,对于降低产品成本,增加企业盈利,提高经济效益将有指导和促进作用.(二)为了便于分析,先从单一产品开始.如果以S表示销售收入,V表示可变成本,F表示基本不变
(1) In science, the mathematical schema used to simulate and describe the relationship between objective phenomena is commonly referred to as a mathematical model. It is characterized by mathematical representations of quantitative changes in the quantity of matter, and even changes in quality. The establishment of mathematical models facilitates further exploration. The inherent law of objective things. As we all know, there is a close relationship between product cost and profit index of industrial companies, namely: income-cost = profit. In order to more accurately describe this relationship, establish a mathematical model of product costs and profits of industrial enterprises. , For the purpose of reducing product costs, increasing corporate profits, and improving economic efficiency will have a guiding and promoting role. (B) For the sake of analysis, start with a single product. If S represents sales revenue, V represents variable costs, F represents basic constant
