Hi All,
At the moment, I'm trying to model a warehouse. This warehouse consists of aisles: long sections of bi-directional paths, intermitted by basic nodes that represent picking locations. Workers walk through these aisles to pick orders. See also the attachment: the nodes are not visible but there are 20 nodes in every aisle.
However, the bi-directional path does not enable workers to walk in two directions. It is possible for workers to encouter each other while traversing the aisle in opposite direction. This will create a blocking situation.
I tried to solve it by using the 'Travel' step, such that the workers travel through 'free space' within a certain width around the warehouse network (setting 'avoind collision' to 'true). The problem however still exists.
Is there a neat solution for this? It is a possibility to introduce all sort of extra bypass paths. However, this will make the model more complex and introduces walked distance biases. One of the purposes of this model is to compare theoretical picking times (based on walking straight through the aisle) with simulation. Adding extra bypass paths would violate therefore the purpose of the model.
Thanks in advance for your suggestions!
