Our manufacturing plants A, B, and C, have the capacities listed below (400, 600, and 800 in January, 400, 600, and 1000 in February, and 400, 600, and 600 in March.) Our sales outlets have a constant demand as shown. Determine how to ship the computers as inexpensively as possible, for each of the three months – i.e. set up three solutions. Do not fail to ship just because you cannot supply the demand – I still want what I have shipped as inexpensively as possible. Also, do not fail to ship just because you have excess capacity.
