Consider the following variables definitions: wm,i,a:= number of actual items from product m produced in plant i in period a um,i,a:= number of non-defective items from product m produced in plant i in period a xm,i,a:=1 if product m is considered for production in plant i in period a, zero otherwise vi,a:=1 if there is any production in plant i in period a, zero otherwise ya:=1 if there is any production in period a, zero otherwise and the following parameters: Ai:= a non-negtive number for each i Fa:= a non-negtive number for each a Bi:= a non-negtive fraction for each i where m=1,,18,i=1,,10,a=1,,13, .

Interpret the meaning of Constraint-(2). 2. What is the total demand per period for each product. 3. What is the plant capacity (maximum total items that you can produce in a plant) per period. 4. What is the minimum number of products that should be produced in a plant during any production period. 5. What is the maximum number of items that can be produced in any plant during all the periods
