1. Warehousing Problem (CPO)
A rectangular warehouse is partitioned into twenty-four 10’x10’ grid square as shown below.
There are two docks located as shown (P1 and P2).
Two types of items will be stored in the warehouse. Item A will take up 14 grid squares. Item B will take up 10 grid squares. The items turn over once a month.
All items enter the warehouse from dock P1 and depart from dock P2.
All travel between docks and storage follow a rectilinear pattern.
All movement into the warehouse is handled by warehouse personnel, but only 1/2 of the item movement out of the warehouse personnel (the other 1/2 is handled by customer-properly supervised).
Any time item A is moved by warehouse personnel, the equivalent of 2 grid square of material can be moved at once. The material movement cost for Item A is $0.50 per foot of distance moved.
Any time item B is moved by warehouse personnel, the equivalent of only one grid square of material can be moved. The material movement cost for item B is $0.20 per foot of distance moved.
