Find the planned-order releases for all itemsMr. Hoi is the manager of a shop that assembles power tools. You have just received an order for 50 chain saws, which are to be shipped at the start of week 8. Pertinent information on the saws is (given in the picture) Suppose now that capacity to produce part E is limited to a maximum of 100 units per period. Revise the planned-order releases for periods 1 through 4 so that the maximum is not exceeded in any period, keeping in mind an objective of minimizing carrying costs. The quantities need not be equal in every period. Note that the gross requirements for E will remain the same. However, quantities in some of the other rows will change. Determine the new cell values for those rows.
