3. (10 points) Short Answer 3 Let's assume that it has been over 5 years since the initial zombie outbreak and you have found hundreds of survivors. Zombies are still a problem but there is also trade developing between bands of survivors. You are going to set up a medical clinic in an abandoned building. There are four areas of your clinic: a waiting room (W), checkup room (C), laboratory (L), and hospital wing where the sickest patients can stay overnight (E). The abandoned building has been partitioned into four areas (I, II, III, IV). You want to minimize transportation costs associated with the medical staff escorting patients, which you expect to be $.10 per patient per metre (with trade comes a new currency). You have the following distance and flow matrices: DISTANCES (metres) FLOWs (loads per week) From/To III From/To CL E I 5 10 0 II 100 0 5 III 5 L IV E 18 5 1. What is the distance (in metres) from area IV to area II in this new facility? (1) III W IV 20 10 W 80 50 5 30 20 38 20 2. What is the total flow (patients per week) between department W and department L? (1) 3. If you were to locate departments W, C, L, and E in areas I, II, III, and IV, respectively, what would be total weekly costs? Show your work. (3) 4. What is the least costly layout? (2) IV 5. What are total weekly costs for the least costly process layout? Show your calculations. (3)
