Question 1 (25 marks) Namibia Enterprises produces a single product called product N. The company requires 30 units in October, 30 units in November and 20 units in December. The demand is supposed to be met every month. However, should there be a demand backlog, the cost of such a backlog per unit is N$5 per each month. This means that if 1 unit demanded in October is only satisfied in December, the backlog cost will be N$5 x 2 months = N$10. All the demand should be met by Page 14 of 15 the end of December. The following table contains the monthly production capacity and production cost per unit:
Month | Production capacity | Production cost per unit |
October | 35 units | N$400 |
November | 30 units | N$420 |
December | 35 units | N$410 |
Each unit in inventory incurs a holding cost of N$20 at the end of each month.
