Hi first of all sorry for my bad English, is the first time I write on this forum!! For my work, i have a problem in a SIMIO model and specifically in the use of vehicles; i will try to explain the problem.... In SIMIO model, i set a facility node wich is the park node of my vehicles. These vehicles must serve event / entity occurring in 3 nodes. Each event is handled by a combination of different vehicles (which I have set in a data table). My events have different priorities (high and low), those high-priority events interrupt those low priority events(as is the case in some of SIMIO simbits). At any given time my vehicles, are insufficient to handle an event.... I wish that before processing an event there was a check on the availability of vehicles; If the vehicles are sufficient in number to process the event they will be send to the node of the event, otherwise I will wait for other vehicles required... Logically, the entity will stand in a queue on the server until it can not be served by sufficient and necessary vehicles. At the moment I'm trying to use a Decide Step to check FreeVehicles; if the Decide Step Condition is True i use a Seize Step to seize necessary vehicles.....and if the condition is False??? How can I wait and check again until the condition is true? I hope that what I wrote is clear... ask me any questions Many thanks to those who want to help me! Marco
