Description:
Coal trains arrive to an unloading facility with independent exponential interarrival times with mean 10 hours. If a train arrives and finds the system idle, the train is unloaded immediately. Unloading times for the train are independent and distributed uniformly between 3.5 and 4.5 hours. If a train arrives to a bust system, it joins a FIFO queue,

The situation is complicated by what the railroad call “hogging out.” In particular, a train crew can work for only 12 hours, and a train cannot be unloaded without a crew present. When a train arrives, the remaining crew time (out of 12 hours) is independent and distributed uniformly between 6 and 11 hours. When a crew&'s 12 hours expire, it leaves immediately and a replacement crew is called. The amount of time between when a replacement crew is called and when it actually arrives is independent and distributed uniformly between 2.5 and 3.5 hours.

If a train is being unloaded when its crew hogs out, unloading is suspended until a replacement crew arrives. If a train is in queue when its crew hogs out, the train cannot leave the queue until its replacement crew arrives. Thus, the unloading equipment can be idle with one or more trains in queue.

Run the simulation for 720 hours (30 days) and gather statistics on:

(a)Average and maximum time a train spends in the system
(b)Proportion of time unloading equipment is busy, idle, and hogged out
(c)Average and maximum number of trains in queue
(d)Proportion of trains that hog out 0, 1, and 2 times

Note that if a train is in queue when its crew hogs out, the record for this train must be accessed. (This train may be anywhere in the queue.)


Deliverables:
Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.

Complete copyrights to all work purchased.

Complete data collected for the program in tabular form. (the statistical data asked in the program).




Platform:
Windows 98, Me, 2000, XP.


Must be 100% finished and received by buyer on:

May 17, 2002 EDT
Deadline legal notes: All times are expressed in the time zone of the site EDT (UT - 5). If the buyer omitted a time, then the deadline is 11:59:59 PM EDT on the indicated date.

Special Conditions / Other:

Remember that contacting the other party outside of the site (by email, phone, etc.) on all business projects < $500 (before the buyer's money is escrowed) is a violation of both the software buyer and seller agreements. We monitor all site activity for such violations and can instantly expel transgressers on the spot, so we thank you in advance for your cooperation. If you notice a violation please help out the site and report it. Thanks for your help.

(Excellent)
   
Simulations are my lovely assignments. I have made 5 of them on this site (see my portfolio).
I have 10 years in C/C++ development, 2 years in Java, certified by Microsoft. Not a complicated assignment, will do it in a couple of hours. Full comments and thorough testing are guaranteed as usual.
You can trust me; everyone rated me 10 so far.

You did not mentioned in which language would you like it to be done. I would prefer to do it in Java, but VC++ is also OK.

Sincerely

Oleg
