In presence of multiple products: The number of distributors as branches is about 25, while the number of independents is about Using an ordered picking list and an optimal routing obviously may reduce the travel distance. Optimality cannot be arrjgo with full integration of all these decisions Melo et al.

It could be taken as framework to integrate the interrelated decisions I n t r o d u c t i o n 5 arrigoo at a strategic, tactical and operational level for the generic design and control of order picking systems.

Similarity index has a moderate impact. A new customer is considered till the capacity of the RDC is completely committed. Then a Travelling Salesman Problem TSP solver can be applied to construct the minimum Hamiltonian circuit which starts from the supplier, visits all demand points, and minimizes travelled distance.

On the other hand density AA has a more uniform presence on the orders. The course takes place in the traditional way with illustration of the various topics using the projector and whiteboard. Once the 98 slots from the first three and an half spans are completely filled the same procedure skip to the next industrialli. The positioning process starts from the bottom left of the system see start point in Figure I p R is defined as the time between two consecutive shipments from the DC of type p to a distributor.

In general given a period of time t a set of customers is assigned to a distributor in accordance to the partition process of all customers with no zero demand in t. Framework for warehouse design and operation problems A more detailed description of each problem category identified is given in Table 4. In particular, the generic FL problem in logistic systems can be defined as the taking of simultaneous decisions regarding design, management, and control of a generic distribution network: Anyway after about three years of hard maneuvering, I have been now almost approaching the destination.

This paper presents an integrated approach and an automatic tool for the execution of the strategic planning, the tactical planning and the operational planning in a multi-echelon multi-stage multi-commodity and multi-period production, distribution and transportation system.

The hierarchical frameworks, approaches and tools I n t r o d u c t i o n 4 presented in the thesis allow the logistics planner and managers to design inbound and outbound logistics simultaneously optimizing the various problems at different levels of decision in order to reach a global optimum. For an item the index is defined as the ratio of the number of storage addresses in the order picking area that are reserved for the item, to the average number of transactions per order picking period Haskett, Strategic model III, case study.

Managers can decide the exact locations for each pareshci according to the sequence defined by the list, and to a chosen positioning rule. The number of DCs is generally limited to a few, e.

It follows that sometimes the actors across the entire network are mutually interdependent and could develop changing connections. And then it travels to a pick location to retrieve the second load.

Order Closing assignment rule Inspired to the Order Completion principle introduced by Bartholdi and Hackmanin this dissertation a storage assignment rule is introduced, named Order Closing Assignment rule OC. Vehicle routing in full load or adopting groupage mode.

Strategic design, case study A brief presentation and discussion of main results obtained by the application of the strategic models to the indusrtiali study object of this manuscript is reported in this section. The Proposed similarity index is defined by the following: Due to the fact that finding a joint optimal solution for both problems is not a realistic approach for real applications, contact-based solution arriggo alternate between the two problem types.

Pallet systems are used to store large products or for handling large quantities of products. By selecting a threshold limit value of similarity corresponding to a maximum admissible distance between two members of the same cluster it is possible to identify the set of disjunctive trips, i.

Advanced Models & Tools for Inbound & Outbound Logistics in Supply Chain

For this reason it is called also dynamic. Even if the tactical planning is implanti a multi-product and multi-period short-term planning, it can support also a long-term planning. These products might reasonably have high correlation and it may be useful to locate these two products close together within the system and by doing so the travel distance will be reduced. Framework of the tool supporting the proposed approach This paper will focus mostly on the operation planning problems.

Moreover many of the existing D e s i g n o f O r d e r P i c k i n g S y s t e m s 84 papers provide performance evaluation comparing only at least a couple of rules and almost always the proposed method is compared only to the randomized storage rule, ignoring that popularity is the criterion most widely adopted as class-based storage for current warehousing practice Frazelle pwreschi Lezione 34 ore Esercitazione 12 ore Laboratorio 8 ore impanti individuale 96 ore totale ore 6 Crediti Formativi.

The density of picking generated is practically visible on the incidence matrix. Each customer order consists of at least one product of the product mix. Different densities of picking. Nevertheless the clustering approach can be impiantii also after the application of a multi-period LAP model in order to effectively plan and organize the trips of vehicles and containers.

What-if analysis can be conducted by the application of different simulation analyses. Transportation modes road, rail, maritime. It is not unusual to find a facility with tens of thousands of parts.

Although different storage systems may adopt different rules depending on the specific sku profile and storage technology in use, storage assignment policies can be divided into the following four broad categories, each of which has a different impact on the travel time required to retrieve products from storage areas in response to customer requests PetersenManzini et al.

Material handling trend in a CDC. Annual customer demand distribution To keep supply chains running smoothly, companies need to efficiently move, store and physically transport products raw material, goods-in-process, finished goods from one location to another.

They are based on the use of mixed integer linear programming modelling and linear programming solvers combined to the application of Cluster Analysis, heuristic clustering algorithms and optimal transportation rules. In particular this dependency is explicit till this term generates a good saturation of the adopted minimum number of containers travelling from the DC to one or more distributors in a trip.

To avoid sub-optimization, these decisions should be regarded in an integrated perspective Melo et al. Strategic planning module The terms network design and SC network design are usually synonymous of strategic supply chain planning.
