The diagram below represents a process where three components are made stations A1, A2, and A3 (one component is made at each station). These components are then assembled at Station B and moved through the rest of the process, where some additional work is completed at stations C and D. One and only one person is allowed to work at each station. The times given below for each station represent the amount of work that needs to be done at that station by that person, with no processing time variation. No inventory is allowed to build in the system. Station A1 3 minutes Station A2 2 minutes Station B 5 minutes Station C 4 minutes Station D 1 minute Station A3 3 minutes a) What is the hourly throughput (output) of the process? b) Which station is the bottleneck? c) What does it mean for a station to be the bottleneck of a process? d) What is the flow time of a unit consisting of the three components? e) What is the cycle time of the process? f) What is the utilization rate of each worker? g) Can a service company benefit from process analysis? Explain clearly why or why not.

Step 1
The time it takes to complete one unit is the sum of the times at each station: 3 minutes (A1) + 2 minutes (A2) + 5 minutes (B) + 4 minutes (C) + 1 minute (D) + 3 minutes (A3) = 18 minutes Since there are 60 minutes in an hour, the hourly throughput is: 60 Show more…

The following represents a process used to assemble a chair with an upholstered seat. Stations A, B, and C make the seat; stations J, K, and L assemble the chair frame; station X is where the two subassemblies are brought together; and some final tasks are completed in stations Y and Z. One worker is assigned to each of the stations. Generally there is no inventory kept anywhere in the system, although there is room for one unit between each of the stations that might be used for a brief amount of time. Given the following amount of work in seconds required at each station: A - 38, B - 34, C - 35, J - 32, K -30, L - 34, X - 22, Y - 18, Z - 20 a) What is the possible daily output of this "process" if 8 hours of processing time is available each day? b) Given your output in part a, what is the efficiency of the process? c) What is the flow time of the process?

3. Floor-On, Ltd., operates a line that produces self-adhesive tiles. This line consists of single-machine stations and is almost balanced (i.e., station rates are nearly equal). The manufacturing engineer has estimated the bottleneck rate of the line to be 2,000 cases per 16-hour day, and the raw process time to be 30 minutes. The line has averaged 1,600 cases per day, and the cycle time has averaged 4 hours. a) What would you estimate the average WIP level to be? b) How does this performance compare to the practical worst case? c) What would happen to the throughput of the line if we increased capacity at a non-bottleneck station and held WIP constant at its current level? d) What would happen to the throughput of the line if we replaced a single-machine station with four machines whose capacity equaled that of the single machine and held the WIP constant at its current level? e) What would happen to the throughput of the line if we began moving cases of tiles between stations in large batches instead of one at a time?

Revolt Longboards produces skate decks with custom artwork. Assume they have seven workers, one stationed at each of the workstations (as shown in the process flow diagram below). Assume the company operates 8 hours per day. PAINT A FINISH X PREP PAINT B PACK FINISH Y PAINT C The processing time in minutes per unit at each workstation is as follows: 45 min/unit at the PREP station, 63 min/unit at one of the three PAINT stations, 84 min/unit at one of two FINISH stations, and 27 min/unit at the PACK station. (Please round to the nearest whole number for the following three answers) What is the bottleneck time? minutes What is the throughput time? minutes What is the daily capacity in units? units per day Which action would increase the capacity of this process? A. Decrease the processing time at the bottleneck workstation. B. Consolidate the three paint workstations into one, larger work cell with three workers assigned to it. C. Increase the throughput time. D. Add a quality check after the paint step. E. Combine the finish and pack steps.
