- A production process at Kenneth Day Manufacturing is shown in Figure S7.9. The drilling operation occurs separately from, and simultaneously with, sawing and sanding, which are independent and sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel).a) Which operation is the bottleneck?b) What is the bottleneck time?c) What is the throughput time of the overall system?d) If the firm operates 8 hours per day, 20 days per month, whatis the monthly capacity of the manufacturing process?A production process consists of a three-step operation. The scrap rate is 10 percent for the firststep and 6 percent for the other two steps.a. If the desired daily output is 450 units, how many units must be started to allow for loss due toscrap?b. If the scrap rate for each step could be cut in half, how many units would this save in terms ofthe scrap allowance?c. If the scrap represents a cost of $10 per unit, how much is it costing the company per day forthe original scrap rate?Exercise 8-37, 8-38, 8-39 & 8-40 (Static) (LO 8-2, 3, 5) Skip to question [The following information applies to the questions displayed below.]Pacific Ink had beginning work-in-process inventory of $744,960 on October 1. Of this amount, $304,920 was the cost of direct materials and $440,040 was the cost of conversion. The 48,000 units in the beginning inventory were 30 percent complete with respect to both direct materials and conversion costs. During October, 102,000 units were transferred out and 30,000 remained in ending inventory. The units in ending inventory were 80 percent complete with respect to direct materials and 40 percent complete with respect to conversion costs. Costs incurred during the period amounted to $2,343,600 for direct materials and $3,027,840 for conversion.
