【摘要】：目前,企業(yè)信息化應用水平作為衡量各國經(jīng)濟發(fā)展的重要指標,越來越受到企業(yè)的重視,信息化投資力度逐年增加。一直受到重視且作為重要基礎設施建設的電網(wǎng)企業(yè),對于信息化的投資力度也在逐年加大。隨著電網(wǎng)企業(yè)信息化投資規(guī)模的逐步擴大,定量的認識信息化投資對電網(wǎng)企業(yè)發(fā)展的貢獻率,幫助企業(yè)制定科學合理的投資決策這一需求顯得越來越迫切。 本文通過研究和分析國內(nèi)外的相關理論知識,在此基礎上,對電網(wǎng)企業(yè)信息化投資的各個因素及因素之間的作用機理進行深入的研究分析,提出了基于柯布-道格拉斯生產(chǎn)函數(shù)(C-D生產(chǎn)函數(shù))的貢獻率模型,并運用當今主流的開發(fā)框架,研發(fā)了電網(wǎng)企業(yè)信息化投資貢獻率系統(tǒng)。該系統(tǒng)不僅可以靈活的構建貢獻率的相關指標,還可以通過校驗指標數(shù)據(jù),保證指標數(shù)據(jù)的合理性和完整性。最后,利用貢獻率模型計算指標的相關數(shù)據(jù),得到量化的結果。系統(tǒng)通過細粒度的分析指標數(shù)據(jù),實現(xiàn)了貢獻率的輔助分析功能,從而為企業(yè)的投資決策提供支持。本系統(tǒng)具有豐富的展示功能,分析結果直觀易懂。系統(tǒng)采用J2EE的多層架構開發(fā),基于組件架構技術的實現(xiàn),使用iBATIS+Spring+Flex框架構建而成。 該系統(tǒng)可以使企業(yè)的貢獻率評價結果更加科學、合理,能更好地反映電網(wǎng)企業(yè)的運行效益情況,從而為企業(yè)的投資決策提供支持,使投資決策水平再上一個新臺階。目前該系統(tǒng)已經(jīng)投入使用,系統(tǒng)的實用性和高效性得到了很好的驗證,有很好的推廣價值。
[Abstract]:At present, the application level of enterprise informatization, as an important index to measure the economic development of various countries, has been paid more and more attention by enterprises, and the investment intensity of informatization has increased year by year. Grid enterprises, which have been attached great importance to and as an important infrastructure construction, invest more and more in informatization year by year. With the gradual expansion of the scale of information investment in power grid enterprises, it is more and more urgent to understand quantitatively the contribution rate of information investment to the development of power grid enterprises and to help enterprises to make scientific and reasonable investment decisions. Based on the research and analysis of relevant theoretical knowledge at home and abroad, this paper makes a deep research and analysis on the factors and the action mechanism of the information investment in power grid enterprises. The contribution rate model based on Cobb-Douglas production function (C-D production function) is put forward, and the contribution rate system of information investment in power grid enterprise is developed by using the current mainstream development framework. The system can not only flexibly construct the relevant index of contribution rate, but also ensure the rationality and integrity of the index data by verifying the index data. Finally, the quantitative results are obtained by using the contribution rate model to calculate the relevant data of the indicators. The system realizes the auxiliary analysis function of the contribution rate through the fine granularity analysis index data, thus provides the support for the enterprise investment decision. This system has abundant display function, the analysis result is intuitionistic and easy to understand. The system is based on the implementation of component architecture and iBATIS Spring Flex framework. The system can make the evaluation result of the enterprise's contribution rate more scientific and reasonable, can better reflect the operation benefit of the power grid enterprise, thus provide the support for the enterprise's investment decision, and make the investment decision level rise to a new level. At present, the system has been put into use, the practicability and efficiency of the system have been well verified, and it has a good promotion value.
