Warehouses’ management is becoming more important inside the logistics’ world lately, an optimal management implies a working time reduction and it leads to a cost reduction.
The objective of this thesis is to discover the world of warehouses’ management, and especially the warehouse order picking field. For that reason it will be divided into two parts. The first one will be theoretical, and the goal is to acquire a theoretical base. The second one will be more practical, firstly a statistical analysis will be carried out through a factorial design in order to understand the performance of the different routing strategies and when is better to use each. Secondly, the relationship between the response and the travel time will be studied through a correlation study.
In the first part results show that the performance of the optimal routing is much better than the heuristics in all the situations, and as it is commented in the theoretical part an increase in the number of cross aisles benefits all the methodologies, but with some exceptions. It is also proved that using a storage method, the travel time is reduced. While in the second part, the correlation study shows that all the factors have a strong relationship with the travel time.
