CKC manufactures two different types of dog chew toys (A and B sold 1000 count boxes) that are manufactured and assembled on three different workstations (W, X, Y) using a small batch process (see Figuare 7.9) Batch setup times are negligible. The flowchart denotes the path each product follows through the manufacturing process and each product's price demand per week and processing times per unit are indicated as well. Purchased parts and raw materials consumed during production are represented by inverted triangles. CKC can amke and sell up to the limit of its demand per week; no penalties are incurred for not being able to meet all the demand. Each workstation is staffed by a worker who is dedicated to work on that workstation alin and is paid $6 per hour. Total labor costs per week are fixed. Variable overheard costs are $3500/week. The plant operates on 8 hour shift per day, or 40 hours/week. Which of the three workstations W, X, or Y has the highest aggregate workload, and thus serves as the bottleneck for CKC?
