Expandation both of decision unit structure and its optimization method in decision network planning
Lei Guan · Journal of Dalian Maritime University · 2007
To solve the expression difficulties resulting from variety of random sample spaces in decision network planning,an expanded decision unit structure including several sample spaces was presented.Stochastic programming theory was used in the optimization of decision network planning and a new mathematical model considering both of expected cost and risk was established.A solution was given through an example to validate the present model.The calculation result shows that the expanded decision unit structure and the corresponding optimization model can solve the decision problem more effectively in variable sample spaces,and therefore has theoretical significance and practical value.
