In the first phase, it clusters the items into groups based on a measure of strength of joint demand i. Speed profile of the trilateral stackers. These policies are generally a set of rules which can be used to assign products to storage locations and they primarily aim to provide ways for allocating items in an order picking system so that order picking time will be reduced Muppani and AdilManzini et al.

After the explanation of where we proceed to exercise short numerical examples are targeted to a more realistic view of the subject. 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. Furthermore it is interesting observing the value of the travelled aisles: Then the introduction and control of intra-layer flows is achieved.

The turn rate and the similarity of products are analyzed. The algorithm is composed of the following points: Heuristic rules for the assignment of customers demand to the RDC level A brief illustration of the main decision steps executed by the heuristics to reduce the computational complexity of the original MILP strategic model follows.

Scheda Insegnamento

Il corso indirizza gli allievi verso le problematiche industriali dell’approvvigionamento energetico delle varie utenze presenti in uno stabilimento. Pallet racks can be single-deep, double-deep, or arrigi multi-deep. At the first place, I would like to express my sincerely thanks to Prof.

For example, in a four-command cycle described in Sarker et al. The transfer and put away pardschi the transfer of incoming products to storage locations. Operational management optimization, case study To reduce the problem complexity it can be useful to accept a few of the locations and assignments generated by the strategic planning step illustrated in Section 2. Given a cluster, the travelling salesman problem TSP is impiatni and the best Hamiltonian circuit can be identified in presence of a few stops for each vehicle in a trip, i.

This type of system is called high-level or man-aboard system. Combination relationship of six experimental factors with different levels The physical location where present and incoming items will be stored. Each order is made of different products industrialk is based on a specific transportation mode. The Popularity Assignment rule P simply considers the demand frequency of the item types.

Isotime2 rule performs better referring to the other positioning rules. Model I The first strategic model, Model I, for the design of the logistic network is: Figure 1 illustrates the thesis outline.

La serie di approcci metodologici di tipo gerarchico presentati in questa ricerca mirano a diventare un sistema di modellazione che integra le principali decisioni del supply chain management. In fact density EE has a presence of products completely concentrated on few orders. Gianni Montali and Mr.

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

It results to be very complex by the activity of managing and controlling pareschk flows of materials. Update the similarity matrix Industrilai by deleting the rows and columns corresponding to clusters r and s and adding a row and column corresponding to the newly formed cluster. An example of CB rule The clustering process adopts impiantj hierarchical heuristic algorithm, e. In presence of multiple products the generic RDC has a maximum admissible capacity for each product.

Class-based storage This policy provides an alternative that is between and has the benefits of both dedicated and randomized storage. It is based on a time between two consecutive shipments two times the standard configuration i.

This area concerns two main problems. Comparing average results with popularity assignment strategy 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.

Obiettivi formativi in termini di risultati di apprendimento attesi. Analyzed Data The horizon time for the analysis embraces month order profile data. The solver finds the optimum solution to the simplified MIL model that is admissible and hopefully much closed to the optimal solution of the original dynamic model. 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.

The cycle stock is the portion of stock available, or planned to be available, in a given period, excluding excess stock and SS. In particular they are based on an exact correspondence between product quantities and space available in the storage system.

The present research focuses on two well known clustering algorithms to perform this phase: The course takes place in the traditional way with illustration of the various topics using the projector and whiteboard. MILP model, multi period, multi product, capacitated, multi mode, inventory management Optimal solution to the original model Optimal solution to the simplified model OR A s o f t w a r e t o o l 59 when a specific period is selected.

Warehouse as a Crucial Link in Supply Chain Warehousing and the relative order picking process are an essential component of any supply chain. For example S kt is similar to Sk defined in Model I, but impuanti depends on the unit of time t.

Resources, such as space, labor, and equipment, need to be allocated among the different warehouse functions, and each function needs to be carefully implemented, operated, and coordinated in order to achieve system requirements in terms of capacity, throughput, and service at the minimum resource cost. According to this system, the warehouse is one open space in which pallets, filled with products, are stored on the floor or on top of each other e.

The simulations conducted adopting the Proposed similarity index result in a lower total travel distance referring to the simulations adopting Jaccard coefficient as the correlation measurement.

The current simulation system collects the related evaluation index data, for example, the overall travel picking distance.
