【摘要】：众所周知,复杂产品制造业是国民经济和国家安全的重要基础,它的竞争将直接关系到国力兴衰。复杂产品传统的长周期、单品种、大批量制造形式正渐渐地向敏捷、多样、用户化定制的生产方式转变,这种生产方式使得企业更易发生工程变更。为了实现复杂产品制造工程变更中的信息协同,复杂产品制造企业不断加大对信息产品的投入,导致企业信息成本迅速攀升,因此本文应用系统动力学建立模型,对复杂产品制造业的信息成本进行动态仿真,为复杂产品制造业有效控制信息成本提供参考。首先,论文以系统动力学理论为基础,将复杂产品制造工程变更特征与系统动力学特点相结合,从而识别信息成本系统内的各要素,探究系统内影响因素之间的联系。其次,运用系统动力学方法建立复杂产品制造信息成本系统动力学模型,以复杂产品制造业--CX船舶制造企业为例,通过Vensim软件对该企业的信息成本进行动态仿真并就关键因素进行了灵敏度测试。最后,据此为复杂产品制造企业信息成本的管理决策提出一些建议。论文创新地以复杂产品制造工程变更信息协同的信息成本为研究对象,从系统的角度构建复杂产品制造信息成本系统动力学模型,通过系统动力学的仿真模拟实现了信息成本的定量研究,模型结果表明信息技术成本与人力成本是船舶制造工程变更信息协同的信息成本支出的主要项目,是信息成本控制的重点,为复杂产品制造企业有效控制信息成本提供了有意义的参考。
[Abstract]:As we all know, the manufacturing of complex products is an important foundation of national economy and national security, and its competition will directly affect the rise and fall of national strength. Mass manufacturing forms are gradually changing to agile, diverse, customized production methods. In order to realize the information coordination in the complex product manufacturing engineering, the complex product manufacturing enterprise increases the input to the information product. As a result of the rapid increase in enterprise information costs, this paper applies system dynamics to establish a model to simulate the information cost of complex product manufacturing industry. Firstly, based on the theory of system dynamics, the thesis combines the characteristics of complex product manufacturing engineering change with the characteristics of system dynamics. In order to identify the elements of the information cost system, explore the relationship between the factors in the system. Secondly, use the system dynamics method to establish the complex product manufacturing information cost system dynamics model. Taking CX shipbuilding enterprise as an example, the information cost of CX shipbuilding enterprise is dynamically simulated by Vensim software and the sensitivity of key factors is tested. Based on this, some suggestions are put forward for the information cost management decision of complex product manufacturing enterprises. The paper takes the information cost of information coordination of complex product manufacturing engineering change as the research object. The system dynamics model of manufacturing information cost of complex products is constructed from the point of view of system, and the quantitative research of information cost is realized through the simulation of system dynamics. The results of the model show that information technology cost and manpower cost are the main items of information cost expenditure of ship manufacturing engineering change information coordination, and are the focus of information cost control. It provides a meaningful reference for complex product manufacturing enterprises to control information cost effectively.
