At 0637 hrs in the attached model, 3 IRTechs and one IRRN, assemble at Patient ID1's location as shown in the display attached to this submission. All three occupy 3 of the 4 path nodes that interface with the IR5 location. At 0639, the IRMD arrives and pushes both IRTechs to the remaining unoccupied node so that all three of them occupy that single node. This occurs even if the node capacity is set to 1. I would like all 4 staff members to occupy 4 separate nodes.
