Aisle width is 3 meters. There may be some idle time of zone pickers waiting until all other zone pickers finish the current batch.

A s o f t w a r e t o o l 44 Figure 18presents the main menu of the automatic platform LD-LogOptimizer for the execution of the strategic planning. An example of CB rule It can be seen as an infustriali of the across- aisle storage pattern.

LD automatically generates an instance of the optimization problem and tries to solve it by the application of a linear solver. In many cases are developed tutorials on the subject. In return policy the picker can enter and exit at the same end of an aisle.

These costs are extremely high when the transportation mode is ship, plane or train.

Each picking aisle has stock keeping unit locations. The training set has been used to train the approach and define the storage allocations, while the test set is used to simulate the retrieval of customer order from the obtained forward storage area and to evaluate the results.


The adopted procedure for establish the definitive position of each product is the same used in the Stripes rule. ikpianti

The transportation mode from two entities of different levels e. Under the synchronized zoning ondustriali, all zone pickers can work on the same batch at the same time. Hierarchical algorithms are generally constructive and greedy heuristics which step by step generate clusters applying an agglomerative approach, whereas partitional algorithms decompose directly the products into a set of disjoint clusters.

Visualization of the results Similarly to the Case Study I, the effect of the assignment rules can be visualized in the storage system adopting the proposed representation. From the simulation result verification, we know that appropriate Storage assignment rule accompanied with routing planning has a distinguished effect in reducing the overall picking distance.

In presence of more than one product demand. It follows that adopting a storage assignment rule based on product correlation brings certainly the user to choose a subsequent positioning rule under some constraints. Bynzer and Johansson in their paper provided a storage assignment strategy originating from the product structure to reduce the picking time by using variant features as picking information in the construction of a logical assignment policy.

Many in-between variants exist, such as picking multiple orders followed by immediate sorting on the pick cart by the order picker sortwhile- pickor the sorting takes place after the pick process has finished pick-and-sort.

Consequently, the choice of a threshold group correlation measurement strongly influences the number and formation of groups of products. An example of Incidence Matrix Table 16 shows the three levels and the relative groups of product at different similarity. The second phase in the Family Grouping process is the Clustering analysis.

Mulcahy defines large orders as those that have more than 10 lines and recommends that single order picking may yield an efficient picking tour impiznti large orders. As a consequence it is fundamental find the right synergy between the main factors.

Case study40 Figure It follows that sometimes the actors across the entire network are mutually interdependent and could develop changing connections. Products that are frequently ordered together in multi-item less than unit load customer orders should be stored near each other: It is fractionable mipianti nonfractionable: This rule is focused on customers.

Parescui Saturation ratio It identifies the ratio between the effective committed volume for storage and the total volume of the warehouse.

All routes can be showed in a geographical map: Table 10 lists an extract of resulting clusters after the grouping analysis. The what-if analysis is based on more than one hundred different simulated scenarios.

In molti casi vengono sviluppate delle esercitazioni sull’argomento trattato. The RDCs with available capacity are selected and ranked in accordance to the ascending values of the following term: On the other hand today distribution centers often need to process a far higher volume of smaller orders of multiple products which considerably increases logistics costs.

From SKUs to customer orders Even thought there have been various i,pianti to automate the picking process, automatic systems are rarely found in practice.
