Elevator simulation, queue management suggestions



Hi, I am currently working on an elevator simulation in MS Visual C# that will eventually involve at least 2, preferrably 3 elevators running across 5 floors.



There is currently one elevator that will service all floors when a call button is pressed, though adding a 2nd one brings up the problem of which to send.



My form currently includes call buttons for the ground floor and top floor, and up and down buttons for the 1st,2nd and 3rd floors. There are also two timers for the elevator, one to determine the next floor, which it does so by referring to the lift direction and checking a request array. The other timer moves the lift accordingly.



Now obviously, the two elevators can both be at any floor at any time, so handing out requests can depend on a number of variables (lift direction, position and requests).



Hoping someone can help or suggest what direction i can go with this program and if theres any questions just ask I'll provide all the information.



Thankyou in advance
Well.



Think about what you know about lifts.



Go with the theory of 2 lifts, one you have more than 1 lift the logic is the same you just have more options.



Lifts go 1 of 2 ways. up or down.  

A lift at floor 1 told to go up, if someone rings the bell on 3 and the lift is going there or passing there on the way up and the person said "up" on 3.. then it will stop, otherwise if its not due to stop there and the person said down, it wont. The other lift will get the job, or if both are going up, then it will be the first available lift.



Your lift needs states waiting/up/down



Your logic shouldnt be that complex, so, write down in words what your logic choices are, senarios etc



Then you should be ready to code it

the answers are:

what she could do for him
that he needed a room, preferably on the first floor
to let her see if the room was available

regards this is a terrific question and i am glad you asked it.  as i am only in the beginning stages of planning to implement this here (it has not been a requirement yet, but will be soon), i can only add some preliminary thoughts to yours:

microsoft should bold, underline, highlight, and add 50 exclamation points to that statement about keeping queues to a minimum.  the performance hit is staggering, if your system has a high number of concurrent users.  you probably won't notice it in your dev or test environments if there aren't many simultaneous testers, however.

so in the spirit of getting the most protection from the fewest number of queues, i am asking some of the following questions:
* is it sufficient to classify ticket data along the lines of "sensitive, private, privileged" or some other such division, so that i could only create queues based on the sensitivity level of information, and not have to split it further by department/team/function/etc.?  this is a business question that will vary for everyone, of course.
* if the above is possible, i can add a classification enum to the tickets and develop a procedure for which should be selected, and base the queue on its value.  if it is not, or if my ticket category or support team already tells me what i need to know, then this is not even necessary.
* if data sensitivity is not a viable way to divide queues, then do i have certain support groups that need a queue, and all others would not belong to a queue?

in any scenario i have described or implied, this means that (most) teams can see each others' tickets.  this is not a problem for me in this environment, but might be for others.  as long as i wrap a queue around the most sensitive tickets, i do not mind if the rest are out in the open.

again, i have not proven these thoughts in production yet, but hopefully it helps to some degree. you might be able to use synchronize. if you have more than 2 tables, you will need to use it multiple times. What is Delayed Branching ?
  

One way to maximize the use of the pipeline, is to find an instruction that can be safely exeucted whether the branch is taken or not, and execute that instruction. So, when a branch instruction is encountered, the hardware puts the instruction following the branch into the pipe and begins executing it, just as in predict-not-taken. However, unlike in predict-not-taken, we do not need to worry about whether the branch is taken or not, we do not need to clear the pipe because no matter whether the branch is taken or not, we know the instruction is safe to execute.

Moving $I\_1$ after branch


* $I1$ is updating the value of  $R2$
* $R2$ which is used to determine branch condition $R1$
* Value of $R2$ is available after branch
  

$\Rightarrow$ `Cannot be moved`


Moving $I\_3$ after branch


* value of $R1$ is computed in this instruction
* $R1$ is the branch condition
  

$\Rightarrow$ `Cannot be moved`


Moving $I\_4$ after branch


* $I4$ is simple store instruction used to store R1 in memory
* program execution will have no effect if this is placed after conditional branch
  

$\Rightarrow$ `Can be moved`


Moving $I\_2$ after branch


* It update the memory location to place the storing of conditional branch instruction $R1$
* If moved after branch , when compiler reaches $I4$ program execution will stop
  

$\Rightarrow $ `Cannot be moved`
