Study of dynamic economic system with aftereffects
摘要
Economic system has phase characteristics during its developments, and certain decisions must be made during each stage, thus forming a multi-stage dynamic decision making economic system. As to this system, previous decisions have some aftereffects on its future developments, which has fundamentally contradicts the presupposition of programming methodology in Operation Research. In order to solve the problems arising from optimized theory research about the economic system, this paper defines the concept of dynamic system with aftereffects, points out the difference between its aftereffects and those of traditional stochastic processes,studies how the past decision effects on the value of optimal utility function, and gives an example on this base to illustrate its application in exploitation of oilfield.
