Question 1 (a) Rojun Ltd. Co has five types of machines, V, W, X, Y and Z to be assigned to five jobs namely; A, B, C, D and E on the basis of one and only one. The table below shows the amount of hours that each machine would take to do each job. The company wants to minimize the number of hours the machine will be used to do the job assigned. Required: Using the Hungarian method, determine the company's optimal assignment. (8 Marks) Question 2 The distribution system of Jones Ltd Co. has the following constraints. The transportation cost per unit (in Shillings) from each factory to every warehouse is given in the table below. Required: (10 Marks) You must check for optimality in each case using Modified distribution method. a) Using the NWCM, determine the initial transportation cost hence the optimal solution. b) Using the LCCM, determine the initial transportation cost hence the optimal solution. c) Using the VAM, determine the initial transportation cost hence the optimal solution
