folku blackboard.com/bbcswebdav/pid-1591378-dt-content-rid-10061262 2/cous (ISOM Fabrication) ISOM Fabrication is a job shop with the three production stations below. The rate shown at each station is the process capacity of that station 2/day 1/day 3/day 7 (oosQ] asOM Fabrication) In the process flow diagram above, the process capacity of the centire system is A) l/day B) 2iday C) Uday D) 6/day 8] tooso) (ISOM Fabrication) In the process flow diagram above, suppose raw materials arrive at the rate of 3/day and demands for the final product originate at the rate of 6/day. The throughput (the rate at which the system generates money) of the entire systems is A) 9iday B) C) 3/day D) 2day E) liday ssppose the process capacity 9 (0oso1 (1SOM Fabrication) In the process flow diagram above, s (I/day) of Station Y is increased so S/day y. The process capacity of the entire system will be (Hint: This question does not depend on either supply or demand in the previcus question) A) 10day B) Siday a) I-day C) 3 dayExplanation / Answer
Answering the first 5 questions:
bottleneck = 1/day
Hence, process capacity = 1/day
Answer: Option A
8. Given, demand = 6/day
Flow rate = 3/day
Throughput rate = 6/3 = 2/day
Answer: Option D
9. If process capacity of station Y is changed from 1/day to 5/day, then it does not remain the bottleneck process.
New bottleneck = Station X with 2 /day
Process Capacity = 2/day
Answer: Option D
10. As assembly is needed in welding process, we need to have a complete batch from sawing and sanding as well as drilling. Hence, welding slows down the system and is a bottleneck process.
Answer: Option D
11. The average flow time of a queue will increase if the mean service time increases or the standard deviation of service time decreases.
Answer: Option B
