Initially you will be given the map of the warehouse that includes the start location of each picker, the location of a number of fixtures that contain the inventory you need to pick and the location of the dispatch desks. You then must decide what order a picker should to retrieve items and take them to a dispatch desk for processing. Each picker has a load capacity, a list of items types they can carry and a movement speed, so selecting the right picker for the job is essential. Each item that requires picking has a size and item type (e.g. food, fragile etc) associated with it. Each pack station also has a throughput speed and a list of item types they accept so again careful planning is required to get the optimal solution.
