Question 6 7 / 7 pts Use the previous transshipment problem (Walton Water). How many units are sent from Richmond to the St. Louis transshipment point? How many units are sent from St. Louis to Boston transshipment point? 3000 | 3000
2500 | 0 Correct! 0 | 0 0 | 3000 Question 7 7 / 7 pts Use the previous transshipment problem (Walton Water). How many supply constraints (nodes) are in this model? How many transshipment nodes are in this model? How many demand constraints? Correct! 3 | 2 | 3 2 | 3 | 4 4 | 3 | 2 3 | 3 | 3
Question 8 7 / 7 pts Use the previous transshipment problem (Walton Water). What is the overall (optimal) cost of the transshipment plan?
Question 9 0 / 7 pts The manager of Five Stars Store has five employees available to assign to four departments in the store: lamps, sporting goods, jeans and linen. The manager wants each of these departments to have at least one employee in each department but not more than two. Therefore, three departments will be assigned one employee, and one department will be assigned two. Each employee has different areas of expertise, which are reflected in the following average daily sales record for each employee from previous experience in each department: Department Employee Lamps sales Sporting goods sales Jeans sales Linen sales 1 130 190 220 90
2 275 300 190 100 3 180 225 180 140 4 200 120 170 160 5 150 170 250 180 The manager wants to know which employees to assign to each department in order to optimize expected sales. Assume the Xij represents the decision variable whose value tells the manager which employee(s) get assigned to which department. Here ‘i’ is used as the employee index (1, 2, 3, 4, 5) and ‘j’ is used as the department index (1=lamps, 2=sporting goods, 3=jeans, 4=linen). Formulate a linear programming model for this problem and answer questions #9-10. How many decision variables would there be?
