![]() The average time for security check of male passengers (126.7 s) is longer than that of the female (96.9 s). and we set up the real values artificially. 4 (c), a relatively constant number of passengers (about 68) was inspected in each counter of the security check area, while most of passengers waited in line in the check-in hall. In this case, the stock will be negative for one time step (around 1-10 miliseconds). ![]() ![]() The formula finally states that if the next iteration will give you a negative stock, then make the flow rate equal to 0 instead of 0.1Īnd the event is a conditional event with the following condition: stock<=0 The unmatched flexibility found in AnyLogic allows users to capture. In this case the time unit is 1 second, so I'm dividing by 1, so I don't need to put that division. What is AnyLogic AnyLogic is the standard in multimethod modeling technology, delivering increased efficiency and less risk when tackling complex business challenges. The flow rate is never 0.1, the real value is 0.1*(time Step)/(time Unit). I multiply the time step by 0.1 since that is the flow rate you have chosen. using the one mouse click in calendar, or setting minimum or sets of fixed number of days selection using 2 mouse clicks (check in and checkout dates). GetEngine().getNextStepTime() is the time in which the next calculation will occur, so getEngine().getNextStepTime()-time() will tell you the time step for the next iteration (The numerical methods to calculate the steps used by anylogic change for each iteration, so you have to do this). This trick will give you an inexact number close to zero, but it's always good enough:Įase, In flow, put the following formula: stock-(getEngine().getNextStepTime()-time())*0.1<0 ? 0 : 0.1 So I will show you 2 possible tricks to do this Remember System Dynamics is a continuous simulation technique and since it uses steps it's not perfect. ![]() A question that should have a very obvious answer, but no.įirst and most important: there is no option that you can set to define 0 as the minimum value of the stock because the flow will continue wanting to take from the stock no matter what, so what you have to do is to change the flow when the stock is 0 (or near 0).
