Using the LP problem in the text shown in Example, run a linear program to find the following:
1. The coal unloading machinery at plant 2 is going to be taken out for maintenance for 1 week. During the maintenance work, no coal can be delivered to plant 2. The plant management would like to know if this should be done in week 2 or week 3. The decision will be based on the overall 3-week total cost for running both plants.
2. Could the maintenance be done in week 1? If not, why not?
Use as initial conditions those found in the beginning of the sample LP executions found in the text, that is, V1 (1)=70,000 and V2 (1)=70,000.
Example
We are given two coal-burning generating units that must both remain on-line for a 3-week period. The combined output from the two units is to supply the following loads (loads are assumed constant for 1 week).
