HELP WITH COMPLETING THE MODEL.

I've asked this question several times all with incorrect answers.

COMPLETE, READABLE, AND CLEAR ANSWERS PLEASE.

that no shortages are allowed. this situation. Let Dj= annual demand for item j Cj= unit cost of item j Sj= cost per order placed for item j wj= space required for item j W= the maximum amount of space available for all goods i= inventory carrying charge as a percentage of the cost per unit. The decision variables are Qj, the amount of item j to order. The model is Minimizes.t.j=1N[CjDj+QjSjDj+iCj2Qj]j=1NwjQjwQj0. is the average amount of inventory). Construct and solve a nonlinear optimization model for the following data. Complete the model.
