【摘要】：现代经济生活在满足人们对各类工业产品越来越高需求的同时,也产生了资源浪费、能源短缺等诸多环境能源问题,改变生活、生产方式成为其解决之道,再制造这种新型生产方式就属于其中之一,并受到全社会的关注。而伴随着再制造的发展,旧件回收、再制造加工和销售的不确定性对再制造的决策管理造成了困难。本文具体针对某工程机械再制造企业遇到的问题,运用系统动力学仿真方法,建立工程机械再制造供应链决策支持系统,为管理者选择合理有效的决策方案提供分析工具。本文主要研究内容如下：第一步进行系统分析。首先,研究工程机械再制造过程中存在的问题,并对本文决策系统的业务需求和所需研究方法进行简要分析。其次,对再制造供应链的网络和业务流程进行总体分析,并详细地分析了本文决策系统的功能结构。另外,着重研究了系统中各模块的数据流程,并进行功能分析和绘制数据流程图。这一步主要为系统设计提供数据分析基础。第二步进行系统仿真模型设计。建立了工程机械再制造供应链决策系统的仿真模型,并完成模型中参数和数学方程式的设置。通过仿真分析检验模型的有效性,以及实现了对再制造处理过程的仿真。最后,将其模型内部仿真运算过程用于指导本文决策系统算法程序的设计。第三步完成系统的设计及开发。首先,完成了决策系统的总体架构设计、数据库配置和数据表设计,并对查询、系统动力学仿真算法、量本利分析和决策树分析这四项方法的程序进行详细设计。然后,基于功能结构的设计,利用.NET开发框架完成了系统架构的搭建及功能界面的设计,并通过系统评估检验了该平台的有效性。
[Abstract]:Modern economic life not only meets the increasing demand for various industrial products, but also produces a lot of environmental energy problems, such as waste of resources, energy shortage and so on. This new mode of production of remanufacturing is one of them, and has attracted the attention of the whole society. With the development of remanufacturing, old parts are recycled. The uncertainty of remanufacturing processing and sales makes the decision management of remanufacturing difficult. In this paper, aiming at the problems encountered by a remanufacturing enterprise of construction machinery, the simulation method of system dynamics is used. A decision support system for remanufacturing supply chain of construction machinery is established to provide analysis tools for managers to choose reasonable and effective decision plans. The main contents of this paper are as follows:. The first step is system analysis. Firstly, the problems existing in the remanufacturing process of construction machinery are studied, and the business requirements and necessary research methods of the decision-making system are briefly analyzed. The network and business process of the remanufacturing supply chain are analyzed in general, and the function structure of the decision system is analyzed in detail. In addition, the data flow of each module in the system is studied emphatically. Function analysis and data flow chart are carried out. This step provides data analysis basis for system design. In the second step, the system simulation model is designed. The simulation model of the supply chain decision system for remanufacturing of construction machinery is established, and the parameters and mathematical equations in the model are set up. The validity of the model is verified by simulation analysis. Finally, the internal simulation process of the model is used to guide the design of the algorithm program of the decision system in this paper. The third step is to complete the design and development of the system. Firstly, the overall architecture design, database configuration and data table design of the decision-making system are completed. Then, based on the design of functional structure, using .NET development framework to complete the system architecture and functional interface design, the four methods of quantitative cost-benefit analysis and decision tree analysis are designed in detail. The effectiveness of the platform is verified by systematic evaluation.
