随着科学技术的发展和现代化设备管理的要求,每个工程单位对所需要的工程机械产品的可靠性和维修性要求越来越高,这就有必要对产品的可靠性和维修性作一权衡分析。本文运用价值工程中的最合适区域法对产品的可靠性和维修性作一评价和分析,以期使工程单位选择到既经济又有高的可靠性和维修性的工程机械产品。一、什么是最合适区域工程单位在选择工程机械产品时,不仅考虑机械产品的可靠性和维修性,而且还要考虑产品的成本和功能,通俗地讲,就是要选择物美价廉的产品。因此,就要分析工程机械产品的功能与成本,需要围绕价值系数V=1确定
With the development of science and technology and the requirements of modern equipment management, each engineering unit has higher and higher requirements on the reliability and maintainability of the required construction machinery products. Therefore, it is necessary to make the reliability and maintenance of the products a Trade-off analysis. In this paper, we use the most suitable regional method in value engineering to evaluate and analyze the reliability and maintainability of the products so as to make the engineering units choose the construction machinery products which are both economical and high in reliability and maintainability. First, what is the most suitable area Engineering units in the selection of construction machinery products, not only consider the reliability and maintainability of mechanical products, but also consider the cost and function of products, in short, is to choose inexpensive products. Therefore, it is necessary to analyze the function and cost of construction machinery products, we need to determine around the value of the coefficient V = 1
