### Problem Statement

A customer requires during the next four months, respectively, 50, 65, 100, and 70 units of a commodity (no backlogging is allowed). Production costs are \$5, \$8, \$4, and \$7 per unit during these months. The storage cost from one month to the next is \$2 per unit (assessed on ending inventory). It is estimated that each unit on hand at the end of month 4 could be sold for \$6. Formulate an LP that will minimize the net cost incurred in meeting the demands of the next four months.

### Assumptions

• No inventory at beginning of month

• Unlimited capacity

• Other costs in production were ignored

### Formulation

• Xt = number of commodities produced each month during month t

• it = number of commodities on hand at the end of month t

• where t=1,2,3,4 for each month in the problem.

• O.F MINIMIZE COST

Z = 5x1+8x2+4x3+7x4+2i1+2i2+2i3-6i4

### Report to Manger

• The minimum cost we calculated is \$1,525
