【摘要】 企业资源计划(Enterprise Resource Planning，简称ERP)是采用先进管理思想对企业所有资源进行有效管理的集成软件系统；ERP可为企业进行决策、计划、控制与经营业绩评估等系统化管理提供重要手段。产品成本计算与预估是ERP软件的核心内容。因此本文将产品成本计算与预估作为论文的研究对象；论文以ERP框架为基础，针对冷却塔产品的特点，对成本计算与预估方法进行了研究；在此基础上，论文开发了适合冷却塔产品的ERP系统中的物料管理和成本管理子系统。 全文共分为六章。第一章为绪论，主要介绍ERP的发展历程，综述了产品成本计算与预估以及成本计算所涉及的物料清单遍历方法的研究进展。第二章对传统的物料清单(Bill of Material，简称BOM)遍历算法提出了改进，并提出了与之对应的BOM合法性检查算法。第三章讨论了产品成本计算方法，在产品制造成本计算法基础上，提出了针对冷却塔产品成本的宏观统计法。第四章尝试将粗糙集和神经网络应用于冷却塔的物料成本预估，探讨了基于粗糙集和神经网络的冷却塔的物料成本预估方法。本文第五章以BOM遍历的改进算法和宏观成本统计法为基础，开发了适合于冷却塔产品的ERP系统中的物料管理和成本管理子系统。更多还原

【Abstract】 ERP (Enterprise Resource Planning) is an integrated software system, which introduces advanced management idea to manage all resources efficiently for the enterprise. ERP can assist enterprise in many ways, such as making decision, planning, controlling and evaluating. Because the product cost calculation and prediction are the core components of ERP, so they are chosen as the research subject in this paper. Based on the framework of ERP and the characteristic of cooling tower, a practical software for the material and product cost management is developed; they are the subsystems of an ERP software system which fit for the cooling tower products.This dissertation consists of six chapters. The first chapter is about the brief introduction of the development of ERP, and the advances in the fields of product cost calculation and prediction algorithm, also about that of BOM (Bill of Material)which is used in the product cost calculation. An improved BOM traversal algorithm and the corresponding valid check method of BOM is proposed in chapter 2. The method of product cost calculation is discussed in chapter 3. Based on the cost roll-up method, macro cost calculation method is proposed for the cooling tower. In chapter 4,the paper attempts to use rough set theory and Artificial Neural Network in the prediction of the material cost of the cooling tower. In the fifth chapter, a practical software for the material and cost management is developed on the base of improved traversal algorithm of BOM and macros cost calculation method.更多还原
