An electronics firm delivering to its customers by making radio production over the next three months will. There are 1200 radio requests for the first month, 300 radio requests for the second month and 300 radio requests for the third month. A radio production for the first two months would cost $10, while the third month would cost $12. A radio if not delivered in the month in which it is produced, the inventory cost is generated. A monthly stock of a product the cost was set at $ 1.5. Fixed $ 250 for any amount of production the cost of production consists of. Production can only be in the amount of 100 and multiples. According to the fact that there is no stock available at the beginning and the demands must be met on time find the optimal production plan for the three months in question using Dynamic Programming. (Each months determine how much production should be done.)
SOLUTION
Month | Demand | Setup Cost | Inventory Cost | Production Cost |
---|---|---|---|---|
1 | 1200 | 250 | 1.5 | 10 |
2 | 300 | 250 | 1.5 | 10 |
3 | 300 | 250 | 1.5 | 12 |
Dynamic Programming (DP) solution -
Month 1-
Q = 1200
Total Cost = 250 +10*1200 = 12250
Month 2 -
TC1 = 12250+250+10*300 = 15500
TC2 = 250+1500*10 + 300*1.5 = 15700
therefor TC1 is the best production plan
Month 3 -
TC1 = 300+ 1800*10+600*1.5+300*1.5 = 19650
TC2 = 12250 +250+ 600*10+300*1.5 = 18950
TC3 = 15500+250+300*12 = 19350
Therefor TC2 is the optimal way of production plan
Q1 = 1200
Q2 = 300
Q3 = 100
Total Cost = 18950
