IT는 도입 비용이 상당히 높고, 단기간에 그 성과가 나타나지 않는다. 하지만 대부분의 IT 도입 성과 평가 모델은 단기간의 성과만을 측정하기 때문에 신뢰성 있는 예측을 하기 힘들다. 또한 성과 측정을 위해 ROI와 같은 재무적인 요소만을 고려하는 경우가 대부분이다. 보다 정확한 성과 측정을 위해서는 재무적 요소뿐 아니라 시스템 활용성, 고객만족, 기업 이미지 등 비재무적인 요소도 고려하여야 한다. 본 연구에서는 장기적인 관점에서 재무적인 요소와 비재무적인 요소 모두를 성과 측정에 반영할 수 있는 방법을 제안한다. 이를 위하여 본 연구에서는 시스템 다이나믹스와 균형성과표(Balanced scorecard)의 연구 성과를 활용하였다. 시스템 다이나믹스는 장기적인 관점에서 대상 시스템의 행태를 분석하는데 유용하며, BSC는 재무적 비재무적 측면에 관한 평가를 가능하게 해 준다. 또한 본 연구의 유용성을 입증하기 위하여, 본 연구 결과를 유통 산업에 있어서 RFID 도입 성과를 측정하는데 적용해 보았다. 적용해 본 결과 RFID는 도입 비용이 많이 들기에 단기적인 관점에서는 부정적인 결과를 가져오나, 장기적인 관점에서는 기업에 이익을 주는 것을 확인할 수 있었다.

Striking in change that present our country is much by electricity industry reform and the Korea Electric Power Corporation is deciding power distribution system reliability indices every year but power distribution system for reliability evaluation and establishment of investment program are consisting punily. If consider efficient inflection of resources and hereafter power distribution division that is limited for target achievement of schedule level service evaluation and reliability side in operation of the power distribution system, can expect efficient practical use of the power distribution property if gains in electrical side about these change and most suitable investment way consist because there is necessity of electric power plan establishment of area electric power distribution place of business unit. This paper consider proper reliability level and maximum effect through quantitative analysis to gain electrical gains of the power distribution system in reliability side depending on trend DB(Data Base) of data of electric power system composition appliance in this treatise and apply data administration and reliability rate analysis that serve to decide most suitable investment precedence to supply of electric power property to power distribution system present investment algorithm.

Information technology(IT) investment evaluation requires measurements from many perspectives. Except for the case of financial performance, these measurements mostly belong to the qualitative or intangible domain. The problem with IT investment evaluation lies in the fact that it is very difficult to define the qualitative properties against which to measure the performances. This paper addresses the issue of developing the set of performance indices, and defining the structural relationships between them, such that the IT investment evaluation can be done in a systematic, objective and comprehensive manner. We introduce the balanced scorecard strategy map as the backbone reference frame for the generation of performance indices and for the description of the relationships between them. Sample indices for evaluating projects from strategic perspectives are provided with a case example. A step by step follow through of the index generation process has been presented along with the case.

This paper proposes a improved investment priority decision method of the facilities considering the reliability of distribution networks. The proposed method decides a investment order of the facilities combining, by fuzzy rules, the investment priority decision of KEPCO and the priority decision considering reliability evaluation indices. Where reliability evaluation indices are SAIFI(System Average Interruption Frequency Index) and SAIDI(System Average Interruption Duration Index), as referred to evaluation index for sustained interruption. The reliability analysis method of distribution networks applied in this paper utilizes analytic method, where the used reliability data is historical data of KEPCO. Particularly, we assumed that the failure rate increased as the equipment ages. To verify the performance of the proposed method, we applied it with the planned projects to reinforce the weak facility electrical facilities in KEPCO in 2004. The evaluation result showed that, under a limited budget, the reliability of the KEPCO in the Busan region using the proposed method can be enhanced than using the conventional KEPCO's method. Therefore, the results verify the proposed method can be efficiently used in the actual priorities method for investing the electrical facilities.

This study aimed to analyze the replacement investment of the diesel fuel system with the pallet fuel system in the Korean farming sector. Equivalent annual annuity approach was used to resolve a discrepancy of useful life in capital goods and to facilitate investment analyses in an independent perspective. Data was obtained from previous studies on economic analysis of greenhouse tomato, paprika and cucumber. Results showed that the replacement with the pallet fuel system was acceptable irrespective of the remaining period of useful life for the diesel fuel system. In addition, sensitivity analysis with government support level, repair cost, and light and heat energy cost show ed robustness in the possibility of replacement with the pallet fuel system while the speed of replacement was accelerated with an increase in the amount of diesel fuel used and price of diesel fuel, and a decrease in price of the pallet fuel. The result implied that the replacement investment rather than a new investment was appropriate for existing greenhouse farmers and the pallet fuel system was acceptable to replace existing diesel fuel system in producing greenhouse tomato, paprika and cucumber.

최근 건설업계를 포함한 사회 전반에 걸쳐 기업의 경쟁력 및 국가 경쟁력 강화와 효율성 재고를 위한 핵심 전략 수단으로 정보화가 가장 큰 이슈로 대두되고 있다. 하지만 정보화 투자와 관련하여 정보화의 실물적 가치론 정할 수 있는 사례가 없으며, 정보시스템의 경제적 효과에 대한 확신이 없기 때문에 각 기업의 경영자들은 정보화에 대한 투자 의사결정에 어려움을 겪고 있다. 정보화 평가는 기업의 IT 투자의사결정을 도와주고, 기존에 구축된 IT자산의 효율적 활용을 유도하여 기업 경영목표의 달성과 기업가치 극대화를 이루기 위한 필수적인 도구이다. 이에 본 연구는 건설 업종의 정보화 수준을 지속적으로 모니터링 할 수 있는 정보화 평가 시스템을 개발하여, 건설 산업의 정보화 투자 유도 및 정보화 수준향상을 도모하고자 한다.

The interest in economics and efficiency of IT investment is growing as the amount of overall governmental IT investment steadily increase. Accordingly, there is a strong need to determine whether the expenditure incurs effectively for IT investment and to accurately analyze the economics of IT investment, In this perspective, this study discusses the prior researches on concepts regarding the analysis of IT investment management framework as proposed from academic and professional perspectives in advanced countries' government sectors. Thereafter, an adoption of IT investment management (ITIM) framework has been considered so as to enhance the performance of ICT initiative projects in the public sector. In the suggested IT investment management framework, we suggest economics and efficiency of public IT investment should be improved by integrating ICT project selection and control as well as evaluation stage into single governance framework.

During the last decade many enterprises spent a huge amount of money for investment on Information Technology (IT) & Information System (IS) to attain competitive advantage and to maximize their business performance by satisfying the various requirements of customers. Under such circumstances, methodologies for evaluating IT impact on business performance are very important issues for strategic decision making on investment. In this study, we propose a performance evaluation model that adopts the concept of the Balanced Scorecard (BSC) and the Value Chain to analyze the financial impact and non-financial impact of IT & IS at each critical work area. This model combines the 4 evaluation areas from BSC and 6 critical work areas from Value Chain and measures the Key Performance Indicator (HPI) and the effect of KPI. Also, we present a case study of which the evaluation model has been conducted on a major manufacturing company. finally. we address some important notes to improve the IT & IS performances in the real-world.
