## Important Questions

- Explain briefly the characteristics of a queuing system.
- A TV repairman finds that the time spent on his jobs has an exponential distribution with mean 30 minutes. If he repairs sets in the order in which they come in, and if the arrival of sets is approximately Poison with an average rate of 10 per 8 hour day, what is repairman’s expected idle time each day? How many jobs are ahead of the average set just brought in?
- Find the optimal economic order quantity for a product having the following characteristics: Annual demand=2400 unit Ordering cost=Rs.100 Cost of storage=24% of unit cost
