Researches On The Theories And Methods Of Total Investment Control In Government Projects

The present research on international total cost management is still limited within the discussion of conceptions and theory, and has no prominent advancement on the methodology till now. And the research on its concrete and practicable techniques is also very short. The theory of total investment control on domestic governmental investment project is undergoing the great transition and in dire need of advanced theory as the director. This paper on behalf of the government plans to explore three aspects, namely, the theory of total investment organization management, the object establishment of total dynamic investment control, and the optimization of total dynamic investment control, seeks after advanced methods and builds up the mode of total investment control in accordance with the special situation of China and the international convention. The theories of TIC are beneficial to the hot problems'settlement in governmental investment projects of amounting to 600 billion per year such as"body devoid","three surplus", peculation, and corruption etc, securing the smooth execution and having some surplus, and supplying decision guarantees and reform gist for governmental investment decisions, administration sectors and executants.To do so, based on the present theories and methods of the international engineering cost management and the present situation of the home reform in the government-invested projects, this paper suggests as followings.Firstly, the investment estimation and control ought to be scientific. According to the theories of WLC (Whole Life Cost), CS (Cost-significance) and ILS (Integrated Logistic Support), this paper sets up two model, one the total investment estimation model based on the nonlinear theorems like BPNN (Back-Propagation Neural Network), FIS (Fuzzy Inference System) and FC (Fuzzy Clustering), another the total investment control model on a basis of nonlinear control theorems such as Pontryagin Theorem, Earned Value Management and GM(1,1). The case analyses are made and prove that the models'reliability and accuracy are well.Secondly, the management system of government-invested projects should be reformed. It is a core to set up a double-agency system with the government-invested management bureau and contractor. Then based on the theory of species'competitive evolution, it is important to make up an inner and outer supervision system of...
