- 7. The number of service channels.
- 9. Last in First Out (LIFO), also called
- 11. Waiting line theory can be used to analyze the delays at the toll booths of bridges and tunnels.
- 12. Waiting line theory can be used to improve the customers service at restaurants,cafeteria ,gasoline service station , airline counters,hospitals etc,
- 13. Waiting line theory can be used to determine the proper determine the proper number docks to be constructed in the building of terminal facilities for trucks &ships.
- 14. Several manufacturing firms have attacked the problems of machine break down &repairs by utilizing this theory . Waiting line theory can be used to determine the number of personnal to be employed so that thee cost of the production loss from down time & the cost f repairman is minimized.
- 15. Queuing theory has been extended to study a wage incentive plan
- 17. Most of the queuing models are quite complex & cannot be easily understood.
- 18. Many times form of theoretical distribution applicable to given queuing situations is not known.
- 20. What is average time for the hob to be in the regrinding section?
- 22. Pb =arrival rate/service rate=8/16=0.50=50%
- 24. Therefore, Pb’ = λ’ / µ
- 26. The probability that an arrival will have to stand, and
- 28. The mean value of the arrival rate is λ .
- 29. The services time distribution approximated by an exponiential distribution and a nmean rate of services is μ.
- 30. The rate of services is greather than the rate of arrival (μ>λ)
- 32. Pn (n<=2) = 1- Pn(n>2)
- 35. (II) The probability that an arrival will have to stand is given by
- 36. 1-(P0+p1+P2)
- 37. = 1-(7/8)= 1/8
- 38. (III)Expected waiting time of a customer in the queue is given by
- 39. Wq =λ/μ(μ-λ)
- 41. Number of hour for a repairman remains busy in 8 hour day( traffic intensity) is given by
- 43. Hence , the idle time for a repairman in an 8 hour day will be : (8-5) =3 hour
- 44. Expected (or average) number of TV set in the system
- 49. Calculate Arrival rate if service rate is same .
- 50. Calculate service rate if arrival rate is same.
