Question 43 (1 point) An assembly line has a required cycle time of 40 seconds and the total work per unit is 140 seconds. Assume that the theoretical minimum number of workstations could be achieved. What would be the efficiency of that line balance? a) 62.5% Ob) 35.0% c) 100.0% d) 87.5% e) 50.0% Question 50 (1 point) An initial solution has been given to the following process layout problem. Each department is 40m long and 20m wide as shown in the figure below. The distance to move horizontally from one department to the next (center to center) is 40m, and the vertical distance between departments (center to center) is 20m. Initial Layout: 40 m D Flow Matrix (Daily) Department A 30 20 B 15 10 D 15 20m 1 B D Departmen 20 25 Using the flows given above and rectilinear distances as a measurement of costs, which of these four layouts is best to minimize transportation costs? a) D B b) A B D D B A B A D Question 39 (1 point) Use the following information to answer the question below: CaseLogix sells mobile phone cases and also provides repair services at kiosks located in major malls in Alberta. Their most popular model of case is priced at $22 each and CaseLogix purchases them from their distributor for only $10 each. Demand has been steady throughout the year, with 15 units being sold per day. CaseLogix orders this model from a distributor in California and has determined that the purchase administration and receiving handling labour costs total $75 per purchase order. The delivery from the distributor arrives 4 days after ordering. Phone cases do not require a lot of physical storage space however they do gradually become obsolete. CaseLogix has tracked historical data and are confident that inventory annual holding costs equate to 40% of each item's unit cost. Since they can normally substitute an alternative model of case, CaseLogix does not hold any safety stock. Assume they operate 30 days per month (360 days per year). What order quantity minimizes CaseLogix's total inventory costs for this model? a) 24 units b) 450 units c) 303 units d) 1423 units e) 16 units
