Unit 8: Simulation of Queuing System (II)

Table 10 Notes

Table 11

In analysing a new consumer product, the corporation estimates the probability distribution
shown in Table 8.
The following random numbers are to be used:
1. For demand: 28, 57, 60, 17, 64, 20, 27, 58, 61, 30.
2. For profit: 19, 07, 90, 02, 57, 28, 29, 83, 58, 41.

3. For investment: 18, 67, 16, 71, 43, 68, 47, 24, 19, 97.
Required: Using simulation technique, repeat the trial ten times, compute the return on
investment for each trial considering these three factors into account. Approximately,what
is the highest likely return?

Table 12

The annual demand, profit per unit and investment required are presented in Tables 9, 10,
and 11 respectively. A nd from Table 12 it can be said that the highest return is ` 3,15,000 on
the sale of 35,000 units.

8.2 Summary

 A Single-sever service node consists of a server plus its queue.
 The input to the simulators is based on live data collected at McDonalds Fast Food
Restaurant and POSB.
 Our simulation results show that a single-channel queue is more efficient than a multiple-
channels queue. If so, why does McDonalds still want to use the multiple-channels queuing
system?
