| Energy is a kind of important strategic material which shows great influence on the national economy. The development of potential energy directly affects the growth of Chinese economy. Along with the application of strategic rising industry policy in china’s twelfth five-year plan, the amount of renewable energy power project experienced great increase. The investors are facing more and more choice of decision and portfolio in projects, and the problem of resource allocation and optimization in this procedure. Give the consideration of following elements:the dynamiccharacteristics of in-and-out influencing factors of the projects, the huge competitiveness in the investment, and the great influence of the investment in for example geo-economics, a great difficulty has risen in the investment decision of these projects. Some of the quantization of outer factors is easy, while the other is not, the timely character of which has a key influence in decision and information alignment in strategy. Only when the harmony state of these factors is achieved, can the best decision be made.The concept of renewable energy electric power project portfolio management is defined as "in the guidance of usable resources and enterprise strategy, the processing of selection and support of the investment of projects or project groups". The concept of timely strategy alignment can be defined as "the processing of decision making of renewable electric power enterprise under certain strategy and versatile environment"Chapter2analyzed the feasibility and methods of timely decision making. Chapter3analyzed the management model and organization foundation. Chapter4analyzed the method of making timely strategy-alignment decision-making through the mining of KSF. Chapter5made an information system plan based on the theories above. Chapter6elaborated a case based on a realized system.Based on above, the main work of this paper is as followed:(1) As for the decision problems of renewable energy power project, from the perspective of whole lifecycle project portfolio management, a timely correspondingstrategy theory is used, and an evaluation system of renewable energy power enterprises based on KSF (Key Success Factor) is built, while also data mining technology is applied in the timely production of KSF. These results can give guidance to the decision of renewable energy power project.(2) Timely correspondingstrategy theory is brought into the decision of renewable energy power project, thus given limited resources, investors can balance between achieving project goals, project set goals, as well as enterprise strategic objectives, while also keep harmony with KSF. Based on the group company decision, branch company planning and project company operation structure, the management achitechture of decision layer, management layer and operation layer is built. Target is the core factoer of portfolio management, which is based on group company strategy. Based on the organization charactors, the cross point of functional department of branch company and target management in project organizaton is researched, which is to achieve effective management mode of portfolio management.(3) Dynamic KSF project evaluation system is built, and management information system is adopted to collect some data of every individual time spot, and then different time spot of KSF can be obtained, therefore we can evaluate the KSF in whole lifecycle for different project portfolios, whose evaluation results can be useful for the decision of renewable energy power project. This method plays exemplary role in enhancing the decision of renewable energy power project under multi-projectportfolios. Dynamic KSF project evaluation system is built. Relative data is built through management information system, based on which the KSF is created in different time point, so as to excute KSF evaluation on different project portfolio in the whole life-cycle. The evalution result can be used as refference to project decision.(4) Using data mining technology, the timely internal and external conditions of enterprise can be analyzed, and the timely KSF conditions of enterprise can be obtained. Given that the strategic objectives of the enterprise can be written through the front of management information systems, so enterprisestrategic objectives are liked to enterprise KSF. This management method gives useful guidance to renewable energy power project whose decisions are greatly affected by the change of internal and external conditions, and also realizes the correspondence of enterprisestrategic objectives and project goals.The auto KSF produciton mechanism is built, which collection timely data from all business area of a renewable energy company, including projcet construction, project operation and the operation of head quarter. Achieving new KSF of a company by data mining, to realise auto alter of KSF variation. By this method, the decision standard can be timely updated based on enterprise strategy and in-and-out conditions and perform a altering funciton to decision makers.(5) On the foundation of requirement analysis, a design scheme of timely decision-making information platform is built, and the key success factors of this system are discussed, while the system architecture is proposed. Therefore, they provides a practical path to the theory and method in this paper. The reengineering of enterprise’s business process should combine with the requirments of decision system’s data entrance, intergrating KSF’s foundamental data with project business data in the greatest degree. According to enterprise’s characters, system performance, maintainability and modifiability should be considered to design a reasonable system structure, including system’s hierarchical models, persistent storage and objectives. |
