【摘要】：信息技術(shù)在促使各國經(jīng)濟、科技和社會發(fā)展方面發(fā)揮著越來越重要的作用,也已經(jīng)成為企業(yè)間競爭的重要手段和經(jīng)濟實力的重要標(biāo)志。但,我國很多的企業(yè)信息化程度不高,特別是對于中小企業(yè)來說,沒有龐大的資金支持、科學(xué)管理水平低下,風(fēng)險防控能力較弱,他們急需要先進而科學(xué)的管理模式來優(yōu)化現(xiàn)今的管理和經(jīng)營水平。ERP技術(shù)及其相關(guān)的系統(tǒng)的研發(fā)能夠在一定程度上滿足企業(yè)科學(xué)管理的需求,其借助于優(yōu)秀的管理思想、先進的管理技術(shù),從而可以為企業(yè)提供輔助的經(jīng)營決策的功能,為企業(yè)在激烈的市場競爭中立于不敗之地提供科學(xué)技術(shù)的支持。本文的主要研究目的就是通過深入分析ERP項目執(zhí)行過程中所面臨的各種風(fēng)險問題,研究傳統(tǒng)ERP項目的風(fēng)險評估模型無法科學(xué)有效的進行風(fēng)險評估和預(yù)測的原因和弊端,利用SOA技術(shù)、云計算技術(shù)在解決各個應(yīng)用系統(tǒng)分散孤立、無法進行有效的集成等方面的優(yōu)勢,提出了一種新型、智能的ERP風(fēng)險評估云模型,并給出了模型的詳細(xì)設(shè)計方案。同時,針對ERP項目管理過程中可能遇到的風(fēng)險問題,提出在SOA和云計算架構(gòu)模式上構(gòu)建一種智能、有效的風(fēng)險評估系統(tǒng)來對模型進行實現(xiàn),詳細(xì)設(shè)計了模型的各項構(gòu)成元素和執(zhí)行過程、指標(biāo)體系的建立、實現(xiàn)算法等;提出了項目風(fēng)險發(fā)生概率估算算法和ERP風(fēng)險評估云生成算法,從而可以對企業(yè)ERP管理過程中的各項信息數(shù)據(jù)資源進行合理、科學(xué)和有效的管理和分配,完善ERP執(zhí)行過程的風(fēng)險防控功能;重點對云風(fēng)險評估軟件實現(xiàn)架構(gòu)、云架構(gòu)中的Saa S服務(wù)層、Paas服務(wù)層、Iaa S服務(wù)層進行詳細(xì)的設(shè)計與實現(xiàn);另外,本文還對云端風(fēng)險評估數(shù)據(jù)集成與共享平臺的構(gòu)建模式、數(shù)據(jù)集成方式與交換過程進行了研究和實現(xiàn),從而達到構(gòu)建一種高效、智能化的ERP風(fēng)險評估云系統(tǒng)的目的,使得管理者和決策者能夠準(zhǔn)確、全面和及時的掌握企業(yè)ERP項目執(zhí)行過程中的各種風(fēng)險問題,從而為整個系統(tǒng)的發(fā)展提供良好的決策依據(jù)的目的。最后,通過專門的測試軟件,對所設(shè)計的基于SOA的ERP風(fēng)險評估云系統(tǒng)進行運行調(diào)試和性能測試,并對所測試的結(jié)果進行分析,對系統(tǒng)的不足進行了改進。本文所設(shè)計的ERP風(fēng)險評估云模型和基于SOA的風(fēng)險評估云系統(tǒng)的服務(wù)功能集成架構(gòu),利用了當(dāng)前流行的SOA技術(shù)、云計算等技術(shù)進行的設(shè)計,在理論研究和技術(shù)上都進行了創(chuàng)新,因此本課題的研究無論從實用角度還是技術(shù)角度都具有很強的實用價值。
[Abstract]:Information technology plays a more and more important role in promoting the economic, technological and social development of various countries, and has become an important means of competition among enterprises and an important symbol of economic strength. Especially for small and medium-sized enterprises, there is no huge financial support, the level of scientific management is low, and the ability of risk prevention and control is relatively weak. They urgently need advanced and scientific management mode to optimize the current management and management level. ERP technology and its related system research and development can meet the needs of scientific management of enterprises to a certain extent, with the help of excellent management ideas. Advanced management technology, so as to provide enterprises with the function of supporting business decisions, The main purpose of this paper is to analyze the various risk problems faced in the implementation of ERP project through in-depth analysis, the main purpose of this paper is to provide the support of science and technology for enterprises to be in an invincible position in the fierce market competition. This paper studies the causes and disadvantages of traditional ERP project risk assessment model which can not be scientifically and effectively evaluated and predicted. Using SOA technology, cloud computing technology is used to solve the scattered isolation of each application system. In this paper, a new and intelligent ERP risk assessment cloud model is proposed, and the detailed design scheme of the model is given. At the same time, the risk problems that may be encountered in the process of ERP project management are discussed. In this paper, an intelligent and effective risk assessment system based on SOA and cloud computing architecture is proposed to implement the model. The components and execution process of the model, the establishment of index system and the realization algorithm are designed in detail. The project risk probability estimation algorithm and the ERP risk assessment cloud generation algorithm are proposed, which can be used to manage and allocate the information and data resources reasonably, scientifically and effectively in the process of enterprise ERP management. Improve the risk prevention and control function of ERP execution process, focus on the implementation framework of cloud risk assessment software, and design and implement the Saa S service layer of Saa S service layer in the cloud architecture in detail. This paper also studies and implements the construction mode, data integration and exchange process of cloud risk assessment data integration and sharing platform, so as to achieve the purpose of constructing an efficient and intelligent ERP risk assessment cloud system. So that managers and decision makers can accurately, comprehensively and timely grasp all kinds of risk problems in the implementation of ERP projects in enterprises, so as to provide a good decision basis for the development of the whole system. Finally, through the special testing software, The ERP risk assessment cloud system based on SOA is tested and debugged, and the test results are analyzed. In this paper, the ERP risk assessment cloud model and the service function integration framework of the risk assessment cloud system based on SOA are designed, which make use of the current popular SOA technology, cloud computing technology design, etc. Both theoretical research and technical innovation have been carried out, so the research of this topic is of great practical value from both practical and technical perspectives.
