Chapter 75 - Question 04 Homework. Unanswered Same Case as Above: A production process at South Plains Manufacturing is shown below. 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 three assembly operations (the operations are in parallel). What is the bottleneck time? IMPORTANT NOTE: given below is the Capacity per Operation. You need to convert each one of them to Process Times (min/unit) Assembly | 0.7 units/hr Sawing Sanding 6 units/hr 6 units/hr Welding Assembly 0.7 units/hr 2 units/hr Drilling Assembly 0.7 units/hr 2.4 units/hr A 6 minutes/unit O B 10 minutes/unit O C 15 minutes/unit O D 30 minutes/unit O E 45 minutes/unit
