在农业灌排站新建工程和更新改造项目的投资中，对水泵设备进行科学预算和经济性评估是值得关注的重要内容。阐述了全寿命周期成本理论是对水泵设备进行经济性分析的有效新途径，接着在介绍水泵设备全寿命周期成本模型的基础上，对其实现算法进行了初步分析和设计，其中提出了应用BP人工神经网络实现对部分不确定性成本费用的求取。算例分析基于净现值理论和年金概念针对项目规划阶段中水泵的采购环节，进行了全寿命周期成本费用具体预算及经济比较，为设备的科学选购提供了参考依据。初步系统的展示了全寿命周期成本理论应用于水泵设备经济性分析的可行性与现实意义。
Abstract
In the investment of agricultural irrigation and drainage station new construction and renovation project, scientific budget and economic evaluation of water pump equipment are an important content worthy of attention. This paper expounds that the theory of life cycle cost is an effective new way to analyze the economy of water pump equipment. On the basis of introducing the life cycle cost model of water pump equipment, it makes a preliminary analysis and design of its realization algorithm, in which it puts forward the application of BP artificial neural network to realize the calculation of some uncertain cost. Based on the theory of NPV and the concept of annuity, this paper makes a detailed budget and economic comparison example of the life cycle cost of water pump in the project planning stage, which provides a reference for the scientific purchase of equipment. The feasibility and practical significance of applying the life cycle cost theory to the economic analysis of water pump equipment are demonstrated systematically.
