发布时间：2018-11-12 19:52
【摘要】：随着信息技术的飞速发展和全球经济一体化步伐的加快，企业竞争日益激烈。企业间的竞争也可以归结为新产品之间的竞争。产品创新己经成为企业创新的核心任务，而产品系统复杂化已经成为大势之趋，由于复杂产品的研发具有投资高、技术复杂、周期长、风险高的特点。为了确保产品研发的成功，必须进行风险管理，包括风险识别、风险度量、风险传递以及风险控制。在复杂产品研发的过程中主制造商-供应商模式也逐渐被各个企业所接受，本文也着重研究了该模式下复杂产品研发风险的传递。 本文基于经典GERT网络模型，研究了单一研发风险传递模型以及综合研发风险模型及其相关内容，并将其的算法运用到了实际案例中，文章的主要研究内容如下： （1）明确主制造商-供应商模式，建立了材料及零部件供应商-子系统供应商-主制造商的三阶段模型。明确复杂产品研发风险特点，进行研发风险的识别，确定要研究的复杂产品研发风险，并针对进度和费用两个方面的风险进一步研究。 （2）复杂产品研发风险传递的研究包括两个方面：首先，结合单一参数的GERT网络模型，研究单一研发风险因素的传递过程，从进度风险和费用风险两个方面来研究传递的机制和度量方法。然后，结合多参数的R-GERT网络模型，研究综合研发风险的传递过程，将综合研发风险看作是进度风险的函数，通过相关的定义以及定理的证明来确定多参数R-GERT网络模型的求解方法，最后再结合每个子系统供应商对主制造商的风险贡献率，，求出主制造商最终的综合研发风险大小。 （3）用实例对上述单一研发风险因素以及综合研发风险的模型进行验证，并提出相应的风险控制的对策，主要是以某型号飞机的研发过程作为研究的对象，通过整合现有该型号的资料，构建相应的R-GERT模型，求得综合研发风险的传递机制，并给出主制造商控制风险的对策。
[Abstract]:With the rapid development of information technology and the acceleration of global economic integration, enterprise competition is becoming increasingly fierce. Competition among enterprises can also be attributed to competition among new products. Product innovation has become the core task of enterprise innovation, and the complexity of product system has become the trend of the general trend, because the R & D of complex products has the characteristics of high investment, complex technology, long cycle and high risk. Risk management, including risk identification, risk measurement, risk transmission and risk control, is necessary to ensure the success of product development. In the process of complex product research and development, the main manufacturer-supplier model is gradually accepted by various enterprises, this paper also focuses on the complex product R & D risk transfer. Based on the classical GERT network model, this paper studies the single R & D risk transfer model and the integrated R D risk model and its related contents, and applies its algorithm to a practical case. The main contents of this paper are as follows: (1) the main manufacturer-supplier model is defined and a three-stage model of material and parts supplier-subsystem supplier-main manufacturer is established. The characteristics of R & D risk of complex products are defined, the risk of R D is identified, the R D risk of complex product is determined, and the risk of schedule and cost is further studied. (2) the research on risk transfer of complex product research includes two aspects: firstly, the transmission process of single R & D risk factor is studied by combining the GERT network model with single parameter. The transmission mechanism and measurement method are studied from two aspects of schedule risk and cost risk. Then, combined with the multi-parameter R-GERT network model, the transfer process of comprehensive R & D risk is studied, and the integrated R & D risk is regarded as a function of schedule risk. The solution method of multi-parameter R-GERT network model is determined by relevant definition and theorem proof. Finally, combined with the risk contribution rate of each subsystem supplier to the main manufacturer, the final comprehensive R & D risk of the main manufacturer is obtained. (3) to verify the risk factors of single R & D and the model of comprehensive R & D risk with an example, and put forward the corresponding countermeasures of risk control, mainly taking the R & D process of a certain type of aircraft as the object of study. By integrating the existing data of this model, the corresponding R-GERT model is constructed, and the transmission mechanism of comprehensive R & D risk is obtained, and the countermeasures of controlling the risk of the main manufacturer are given.
