Hi there, Just downloaded 5.6b, and loaded up my model. Modified the toolset to include my usual tools, including the Gantt chart, which I use quite a bit, for seeing when things are there or not. Anyhow, I thought it was behaving oddly. Worked fine on some variables, not so on others - seemed to be...

OK, Thanks, I sort of suspected this. I will have a word with Andy and Tony about getting an upgrade. Not sure why your first job comes at time 6 mind you, all the sequences are driven by independent random number seeds so should give the same results unless there is another random number being gene...

My understanding of the function is exactly yours, however when I run the model, at t=1 the job is generated, it enters the queue at t=2, at which...

Hi there, The recalcitrant model is attached below. It is quite simple as I have only just started it this afternoon when I ran into this problem. A lot of it is there for multiple servers, but this version just has one (the others have subscripts but are not free from the start). No cin file requir...

Hi, I have already cut the problem down to identify that yes, there is definitely something going on. I have one queue, one arrival process - a poisson process, one server. Vensim seems to be calculating average age right, but getting maximum age wrong sometimes. So queue starts empty, 1st arrival o...

The queue starts empty, and the flow in is stochastic with a relatively low rate (thus not all time steps have inflow). When the first job turns up, I get an ...
