This example simulates a very basic selling workflow: products are supposed to be jeans (one for each size) as units or packs (only packs enter the system).
At the beginning of each timeslice, the regular workers will order some packs if needed and issue some random final customer sale orders, with the corresponding Reservation Requests.
There are only three Locations:
Packs arrive in
incoming, are moved to
stock where they are
The delivery process moves the goods to the
before issuing Departures.
Everything is processed using the Reservation concepts and related architectural processes, by specialization of the process models provided by :ref:`wms_example_launcher`
This Blok provides a multiprocessed console script that should be partly included in anyblok_wms_base itself.
The principle is that Reserver and Planner processes work continuously, whereas regular worker processes act in coordinated timeslices, which one may think of simulating a day's work.
In the context of examples serving as benches, one does not want to rely on wall clock time, the intent being to run as fast as possible. In that context, the timeslices are useful to postpone the execution of some Operations (typically, Arrivals).
Also, some Operations are performed only at the beginning of each timeslice, in order to keep artificial conflicts to a minimum (in continuously running benches, the very selection of work to be done is a source of conflicts in itself that wouldn't happen in real life).
