I have had some trouble with a conveyor delay in a model.

I know how to construct one with an inflow, an outflow (where the delay conveyor function nests) and a loss outflow. Here I have three separate outflows with respective delay conveyor functions and no loss outflow, since technically there are no losses. Currently I simply have the same function in all three outflows, with weights applied to them (all adding up to 1) and 0 for the loss rates. Funnily enough the stock goes negative. It is not due to initialisation either, since the delay time is significantly shorter (1/40) than the model run time and the stock just keeps draining at the same rate throughout the run.

Any help would be welcome!

Can you post the model so we can have a look?

Tony.

If you have a fixed convey time and no leakage just use DELAY FIXED - this is much simpler and will give the results you want.

Thanks!

Unfortunately I may not post the model but could do a simplified version. I simply remodelled it (closely along the lines Bob described) to get rid of the problem for now
