Essay about operation management HW1 - 1244 Words

1. A manufacturers average work-in-process inventory for a certain part is 1,000 units. The workstation produces this part at the rate of 200 units per day. What is the average time a unit spends at this workstation? 2. The Wilcox Student Health Center has just implemented a new computer system and service process to \improve e ±ciency. As pharmacy manager, you are con- cerned about waiting time and its potential impact on college students who \get no respect. All prescriptions (Rxs) go through the following process: Drop-o ® ! Fill Rx ! Pick-up ! Cashier Assume that students arrive to drop-o ® Rxs at a steady rate of 2 Rxs per minute, with an average of one Rx per student. The average number of students in process (those who†¦show more content†¦All data conform to planners expectations except for one set { the classi ¯cations made by the nurse practitioner. Assume that the triage nurse has been sending 91% of all patients to the Simple Prescriptions area when in fact only 90% should have been so classi ¯ed. The remaining 1% are discovered when transferred to the emergency area by a doctor. Assume all other information from Problem 6 is valid. On average, how long does a patient stay in the ER? On average, how long does a Potential Admit stay in the ER? On average, how many patients are in the ER? Answer to Q1: We know that throughput R=200 units/day, and inventory I=1,000 units. Thus, flow time T=I/R=1000/200=5 days. So the average time a unit spends at this workstation is 5 days. Answer to Q2: a) R=2/min R I T Drop off 2/min 5 2.5 min Fill Rx 2/min 40 20 min Pick up 2/min 3 1.5 min Cashier 2/min 6 3 min b) Based on the chart above, we could calculate: T(stay to pick up)= 2.5+20+1.5+3=27 minutes So the average time in the pharmacy for those students who stay to pick-up their Rxs is 27 minutes. c) For the students back to pick up in 3 hours: T (back in 3 hours)=2.5+1.5+3=7 minutes So the average time in the pharmacy for those students who pick-up 3 hours later is 7 minutes. d) Average T= 0.05*27+0.95*7=8 minutes So the average time that a student spends in the pharmacy is 8 minutes.

It is characterized by the use of digital signals to represent these signals as discrete time, discrete frequency, or other discrete domain signals in the form of a sequence of numbers or symbols to permit the digital processing of these signals.
