Order picking has long been identified as the most labour-intensive and costly activity for almost every warehouse; the cost of order picking is estimated to be as much as 55% of the total warehouse operating expense. Any underperformance in order picking can lead to unsatisfactory service and...

In manual order picking systems, order pickers walk or ride through a distribution warehouse in order to collect items requested by (internal or external) customers. In order to perform these operations efficiently, it is usually required that customer orders are combined into (more substantial)...

The paper presents six ways to move a warehouseman during order picking process. Ratliff and Rosenthal in 1983 developed an efficient algorithm for determining the optimal route. It’s use in practice, however, involves the need to implement the relevant computer system. It is not always...

This paper addresses the Two-level Storage Location Assignment Problem (TSLAP) for two level low-level picker-to-part warehouses. The first level consists of a forward area from which all picking is done. The second level consists of a reserve storage area, from which the forward area is...

The growing mobility of the last years influences the development of economy, environment and space. In this context there are new areas of conflict both between transport and settlement development and between economy and environment. Extra high increases are expected in the multi-modal...
