Which picking method may utilize specific scheduling based on work centers?

1. Discrete picking

2. Zone picking

3. Wave picking

4. Fixed-location storage

The correct answer is: Wave picking

Wave picking is a method that organizes the picking process into scheduled waves, which can be specifically aligned with the operation of various work centers. This approach allows for the coordination of resources and timing to optimize efficiency within the warehouse. By grouping orders to be picked at the same time and in relation to particular production or shipping schedules, wave picking enhances the flow of materials and finished goods, ensuring that they are available precisely when needed. This scheduling flexibility can lead to improved labor productivity and inventory accuracy, as it facilitates better planning and resource allocation tailored to both demand patterns and operational capacities. In contrast to wave picking, discrete picking typically involves picking items for one order at a time, which does not utilize specific scheduling in relation to work centers. Zone picking divides the warehouse into different zones where pickers are assigned specific areas, and although it enhances efficiency by reducing travel time, it does not necessarily incorporate a scheduling aspect tied to work center operations. Fixed-location storage is more about the organization of inventory rather than the methods of picking, as it involves assigning specific storage locations for items without any inherent scheduling element.
