一、寿命周期费用评价的基本步骤寿命周期费用评价或分析的步骤,主要是费用的量化,在此基础上进行决策或分析,以得出指导设备管理的信息.进行寿命周期费用评价的步骤随研究者的需要和所针对的具体问题有所不同,一般步骤如下.1.明确对象(设备、系统、产品)的任务首先必须确定设备应满足的性能要求.该设备的任务必须以目的或目标的形式、具体地加以明确.避免以后制定的方案可能与任务不相适应或选择方案片面.2.列出可以完成任务的各种方案除只有一个方案无选择余地外,应提出几个可供选择的方案,以便今后从中选出可以完成任务且经济性高的方案.这时应掌握各种可能的方案的特征,及使产品获得预期效果所需的费用概算.
First, the basic steps of the life cycle cost evaluation The life cycle cost evaluation or analysis steps, mainly the cost quantification, based on which to make decisions or analysis, to guide the management of equipment information. The steps of life cycle cost evaluation follow The needs of the researcher are different from the specific issues that are addressed. The general steps are as follows. 1. The task of defining the object (equipment, system, product) must first determine the performance requirements that the device should meet. The task of the device must be the purpose or goal. In the form of a specific definition. To avoid future development of the program may be incompatible with the task or choose a one-sided solution. 2. List the various programs that can complete the task In addition to only one program has no choice, we should propose several The options are chosen so that in the future, the most cost-effective options can be selected. At this time, the characteristics of the various possible options should be grasped, and the cost estimates required for obtaining the desired effects of the products should be grasped.
