几年来,我厂住宅建设竣工面积都在四万平米左右,而主体工程平米造价均在160元/m~2以上。开展价值工程可将平米造价控制在140元/m~2以下,这样,每年可为国家节约投资40万元～60万元(按理论计算应该是80万元,但影响成本的因素很多,如人、财、物的资源,企业的经营管理以及社会上的各种因素影响等等)。企业的生产成本包括固定成本和变动成本两大部分,而变动成本是随着工程的总规模也就是工程量的不同而变化的。 设F=固定成本,U=每一单位的变动成本,X=工程量。工程量X对生产总成本C的关系式为:C=F+UX,如右图。
Over the past few years, the total area of the residential construction of our factory has been around 40,000 square meters, and the main square meter construction cost has been above 160 yuan/m~2. To carry out value engineering, the price of flat rice can be controlled below 140 yuan/m2, so that the country can save investment of 400,000 to 600,000 yuan per year (in theory, it should be 800,000 yuan, but many factors affect the cost, such as Human, financial and material resources, business management, and social factors, etc.) The production cost of an enterprise includes two major parts: fixed cost and variable cost. The variable cost varies with the total size of the project. Let F = fixed cost, U = variable cost per unit, and X = engineering quantity. The relationship between the engineering quantity X and the total production cost C is: C=F+UX, as shown in the right figure.
