Each machine can work t hours a month.

There can be p products of each type stored in each month and storing cost c per product per month occur.

Up to 200 units of each product may be stored in inventory at a cost of $0.50 per unit per month. At the start of January there is no product inventory. However, by the end of June there should be 100 units of each product in inventory.

The factory produces product six days a week using two eight-hour shifts per day. It may be assumed that each month consists of 24 working days. Also, for the purposes of this model, there are no production sequencing issues that need to be taken into account.

the question give that variables but I cannot write it on GAMS .
