AMS 553 / CET 554 / MBA 553 :

Textbook,  p. 171  ( p. 186 in the 3rd. edition ) ,    Problem 2.19.

Simulate the system for 10 independent replications. Collect point estimates and confidence intervals at the 95% confidence level (or better - see below) for the following performance metrics :

1. Mean time that a ship spends in the harbour.


2. Probability that an arriving ship does not have to wait for a berth. Note that this is similar to the situation of Example 9.16,  p. 496 ( p. 507 in the 3rd. edition ), of the textbook (and not that of Example 9.21,  p. 506 ;  p. 517 in the 3rd. edition). I shall be discussing this further in class.


3. Average utilization of a berth (not of each berth separately as stated in the problem).


4. Average utilization of crane.

Also report the min min time and max max time for ships in the harbour across the 10 runs.

Notes:

• Take account of the Bonferroni Inequality (see textbook, Section 9.7,  pp. 537 - 540 ;  pp. 542 - 545 in the 3rd. edition), making sure that the ``collective'' confidence level is no worse than 95% .


• A process-oriented implementation will certainly be easier than an event-oriented one. You should find the following Simscript commands/features useful :
  
  
  RESET TOTALS OF command
  
  
  INTERRUPT / RESUME and the TIME.A field of a process notice.
