	::::::::I am afraid that in such a situation, the assignment is so artificial that I don't consider it appropriate. Just to explain - I generally don't expect complicated assignments, however, what you have proposed, is really simple and too much resembling the tasks that have been solved during our lessons. That's why I asked for real data in order to make it more meaningful. If they are not available, I would prefer another assignment. Really, what you have proposed could be solved during one afternoon. This is not what I would expect from a term paper. Thanks for your understanding.

	:::::::I was talking to my friend and he told me that he unfortunately cannot provide me times of transactions, because there is some sensitive data also. But I can have number of transactions during each hour of whole day. So if I will simulate whole day it would be better? He cannot provide me cost structure neither. Maybe I can add to simulation how customers wait for their specials orders.

If there is some special order and it´s not completed from the kitchen yet, it takes kitchen employees to complete this order about 3 minutes in average. Customers with special orders don´t wait in queue, but they sit down and wait for it at the table. So, employee at cashier desk can service next customer.

 :::::It is hard to say in general, what level of complexity is expected. What you have proposed is very similar to the task we did during our classes. For seminal paper, more complicated problem is needed. The appropriate level of complexity could be perhaps apparent from the approved assignments. In the case of your problem, in order to make it meaningful, you could e.g. simulate the whole day with real customer flow. It means much more complex data input reflecting changes during the day. It is perfect that you have someone who can provide real data. Try to get the records from cash registers (just times of transactions are enough) and load them into Simprocess. Next, if you obtain real cost structure, you can build cost model. I would say in the case of orders, it depends on the kind of ordered meal. And what about production part of the whole thing (kitchen) - does it have any influence on the capacities of the restaurant? Etc. Of course, you can also try to suggest something completely different. [[User:Tomáš|Tomáš]] ([[User talk:Tomáš|talk]]) 02:35, 3 January 2016 (CET)

 The simulation should track the number of people in lecture halls, in queues and in any otherwise interesting state such as boredom or stress.
-: I would make it simpler. Don't bother simulating all the day, simulate just as people are coming for the particular event/presentation. Simulate how crowd are assembling at doors, toilets, how people avoiding each other to get their seats. Etc. Just the time let's say +-10 minutes around the beginning of the event. Of course, you need to simulate relative intelligent movement of agents. If you agree, than it is '''approved'''. [[User:Tomáš|Tomáš]] ([[User talk:Tomáš|talk]]) 21:58, 15 December 2015 (CET)
