The demand values for the following 4 weeks for a oompanrlr is as follows: sop, mu, 4m, 43d. The weekly regulartime production capacity is 250 units.

Thereis an inventory oost of $12 per unit per quarter. 15o units are available at the beginning of weekl and the company wants to have at least zoo units at the end of weekd.
