Pre-processing for Model Calculation

For the stochastic expected value programming model in supply chain logistics planning, it is assumed that the external market demand and market price are random parameters while the other parameters within the system are constants at every stage in the planning period. 

Therefore finding the maximum of the expected value of the objective function can be converted into finding the maximum of the expected value of the objective function at every stage in the planning period. The sum of all maximums of the expected value at every stage is the maximum of the objective function.
