Interactive Investment-Distribution Decision Model for Multi-Regional Project Considering Preference Information

With the reformation of project investment and finance system, multi-regional investment project, which is of great investment, long construction cycle, complex influence factors and so on, needs distribution investment among benefited regions. In view of investment-distribution decision problems, this paper introduces some concepts such as optimal expectation level, tolerating limitation, relative deviation value and relative deviation tolerating level and so on, sets up an interactive investment-distribution decision model and gets the solution by the construction of assistant model. The model takes into consider of not only the impact of investment projects on every region but also the economic development degree of regions. Furthermore, it combines preference information of decision maker with distribution result, and owns easy interactive process and low computational complexity. A numerical analysis confirms that the investment-distribution results are easily accepted by all regions.
