The objective is to maximize the following function, where StorageCost is a linear function of Store:
StorageCost
Store
![\[ \Variable{TotalProfit} = \sum _{\text {product} \in \text {PRODUCTS}} \sum _{\text {period} \in \text {PERIODS}} \Argument{profit[product]}\ \Variable{Sell[product,period]} - \Variable{StorageCost} \]](images/ormpex_ex30004.png){kind=small}
