In the preceding problem, instead of inspecting and sorting after every operation, the 20 operations will be divided into groups of five, with inspections after operations 5, 10, 15, and 20. Following the logic of Eq. (21.11), the cost of each inspection will be five times the cost of inspecting for one defect feature; that is, Cs5 = Cs10 = Cs15 = Cs20 = 5($0.10) = $0.50 per unit inspected. Processing cost per unit for each operation remains the same as before at Cpr = $1.00, and Qo = 100 parts. What is the total processing and inspection cost per batch for this partially distributed inspection system?
