6. The method of claim 5 wherein the initial membership value is calculated based on the following function: τ ini = V Border - Min Max - Min wherein τ ini is the initial membership value, V Border is a constraint value of the respective optimization parameter, Min and Max are the minimum and maximum values for the respective optimization parameter.
6. The method of claim 5 wherein the initial membership value is calculated based on the following function: τ ini = V Border - Min Max - Min wherein τ ini is the initial membership value, V Border is a constraint value of the respective optimization parameter, Min and Max are the minimum and maximum values for the respective optimization parameter. 17. The method of claim 6 wherein the plurality of optimization parameters comprise a total cost of the total number of all kinds resources R 1 , . . . Rn, and wherein, for the total cost, the priority factor function for each kind of resource R 1 , . . . Rn is an indicator of change in total cost of the total number of all kinds resources R 1 , . . . Rn with respect to a change in the number of the kind of resource Ri and the cost per unit resource, wherein 1≦i≦n.
