【摘要】：ERP的前身MRP起源于上世纪50年代，但直到如今，由技术上的缺陷所带来的问题依然屡见不鲜。云计算是近些年的研究热点，具有硬件投资低（仅限公共云）、有专业技术维护团队、扩展性强、对用户端的硬件要求低等优点。这些优点恰好与ERP的先天性缺陷相对应，云计算ERP呼之欲出。本文首先结合ERP和云计算的理论知识，提出ERP的4种可行云计算模式；接下来，通过对企业进行访谈，找到影响企业ERP系统的建设和使用等方面的关键因素，最终通过调查问卷收集专家意见，利用层次分析法对备选方案和关键因素进行权重打分，得到决策结论：适合小型企业的ERP云计算模式为SaaS模式，而私有云ERP最适合大中型企业。本文有3点创新之处： (1)采用层次分析法的方式，确定影响ERP的云计算模式选择的各个阶段以及阶段下的各个因素，得到4层的ERP云计算模式选择模型。 (2)采用问卷调查法获得层次分析法所需要的指标分值，专家打分保证了数据的专业性，群决策方式降低了专家主观因素的影响，提高了结果的客观性。 (3)借助专门的层次分析软件，分析了4层ERP的云计算模式选择模型中,下层指标对上层指标的影响权重；得到针对各指标，最具优势的ERP的云计算模式；最后给出大中小型企业最优的ERP云计算模式。
[Abstract]:ERP's predecessor, MRP, originated in -50s, but until now, problems caused by technological flaws are still common. Cloud computing has been a hot topic in recent years. It has the advantages of low hardware investment (public cloud only, professional technical maintenance team, strong expansibility, low hardware requirements on the client side, etc.) these advantages exactly correspond to the inherent defects of ERP, and cloud computing ERP is ready to emerge. In this paper, four feasible cloud computing models of ERP are put forward by combining the theoretical knowledge of ERP and cloud computing. Then, the key factors affecting the construction and use of enterprise ERP system are found through interviews with enterprises. Finally, through the questionnaire to collect the expert opinion, using the Analytic hierarchy process to evaluate the weight of the options and key factors, get the decision conclusion: the ERP cloud computing model suitable for small enterprises is the SaaS model. Private cloud ERP is best suited for large and medium enterprises. There are three innovations in this paper:. 1) adopt the analytic hierarchy process (AHP) method to determine the different stages and factors of cloud computing model selection of ERP, and obtain a four-layer ERP cloud computing model. 2) adopting questionnaire method to obtain the index score needed by AHP, the expert scoring ensures the professionalism of the data, the group decision mode reduces the influence of the expert subjective factor, and improves the objectivity of the result. With the help of the special analytic hierarchy process software, the paper analyzes the influence weight of the lower level index on the upper index in the model selection of cloud computing of four layers of ERP, and obtains the cloud computing model of ERP, which has the most advantages for each index. Finally, the optimal ERP cloud computing model for large, medium and small enterprises is given.
