The Washinglon Chemical Company produces chemicals and solvents for the glve industy The production proctss is divided into several "Tocused tactocies," each producing a specific set of products. The time has come is prepare the production plan for one of the focused factories. This particular factory produces five products, which must pass through both the reactor and the separator. Each product also requires a certain combination of raw materials. Production data are shown below. "The total time avaliable has been adjusted to account for setups. The five products have a proscribed sequence owing to the cost of changeovers between products. The company has a 35 -day cycle (or 10 changeovers per year per product) Consequently, the time for these changeovers has been deducted from the soal fime avalable for these machines The Washington Chemical Company has a long-teem contract with a major glue manufacturer that reguires annual peoduction of 4,000 pounds of both products 3 and 4 . Moce of these products could be produce because demand currently exceeds productisn capacly. a. Assume that the objecthe is to maximize profits Let x1= annual production quantity of product 1 . x2= annual production quantity of product 2 , x3= annual production quansity of product 3 , X4= annual production quantity of product 4 . x4= annual production quantity of product 5 A linear programming software shows that the optimal values foe x1,x2 and x2 are: x1=16,836x2=5,429,x3=4,000 What are the optimal values for X4 and X5 ? x4= (entor your response rounded to the nearest wholo number) x5= (enter your resporise rounded to the nearest whole fumber)
