In the third edition of “What’s New in AnyLogic 7?” I am excited to explain the capability of AnyLogic 7’s new Process Modeling Library, to support the “pull” protocol of working with entities. Start by taking a look at the simple model below, built in AnyLogic 6, a conveyor that begins with a service point. The entity on the conveyor has to free the space set by the distance between entities parameter, for the new entity to enter the conveyor. The conveyor cannot receive the next entity until the first one moves.
