Pick by light ?
Isolated, the pick by light picking system gives the best speed results.
In his area of operation, the picker receive visual instructions at the place of separation. The implementation and costs of this
system are high and the area of operation is narrowed. Mobility or relocation of the system requires additional high costs..
Pick by only voice ?
The positive side of this system is that the picker has both hands free. Disadvantages include the length of command,
working in a noisy environment, the need for high concentration over a long period of time and longer training period.
Pick by PDA ?
Mobile computers with scanners meet all process needs in modern storage systems.
What stands out as a basic flaw is the robustness and the fact that they take the hands of picker.
Worker diverts his gaze from the task, his focus is disturbed and a
cognitive break is created, the picker can lose the thread where he stopped, which opens the possibility of error.
