Cristina Mora, two essential members of the crew always ready to grab me off the water when in need and dispense impressive advices.

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

Nevertheless the model can be update to admit multi sourcing suppliers in a generic period of time t. Operational planning of a production- distribution logistic system The aim of the operational planning is the daily organization of vehicles fleet and routings to supply products from the sources and production plants to the customers Pods in accordance with a very large number of constraints, e.

Minimizing this distance is affected by several factors e. Another way to store ipianti pallets behind each other is the so called drive-in or drive-through racks. A s o f t w a r e t o o l 52 in case the RDC is already paareschi, the adopted measure of cost is: Analyzed Data The horizon time for the analysis embraces month order profile data.

The logistics revolution has changed the impiantj of warehousing. The instance representing the case study areigo made of 2 sources, distributors, points of demand, variables and constraints. Consequently if I imianti R decreases the customer service level increases at the generic point of demand and the logistic cost increases too, because the level of saturation of vehicles and containers reduces and the transportation cost for the unit of product increases.


Similarly, indudtriali each point in time t within the planning period, for each kmpianti and for each stage of the logistic network it is possible to define optimal deliveries with the specification of the products quantities, the location of the generic supplier and the location of the generic demand point. Thesis Outline Chapter 1: BFI Coefficients, and Similarity Matrix Parechi the nn algorithm for the grouping process, 3 levels of clustering are obtained.

About four hundred orders are generated randomly by a computer. As a consequence congestion may occur and hence it is a natural extension to consider the waiting times between two pickers for future study. For this purpose the distance parameter max q dassociated to the type of distributor q, has been introduced. The splitting of initial data is a necessary step in order to avoid the so called overfitting data problem and outcome bias. The form illustrated in Figure 23 presents main results obtained by the application of the proposed strategic optimization.

The course aims to provide the mechanical engineering students a systemic approach, techniques and methodologies widely adopted in industrial context. Design of Order Picking Systems Induetriali 6: Bartholdi and Hackman conversely recognize three main uses: Metodi e criteri di valutazione dell’apprendimento. Figure 30 summarizes the main steps for the operational planning a implemented by LD- LogOptimizer. Therefore the general similarity of the product mix is not strong.

In other arrifo this model also consider the minimum and maximum number of containers for the generic trip from the DC to the distributors. This refers to arigo planimetric dimensions of the storage area and can be defined as the ratio between the length and width of a warehouse e.

The location of these potential entities is given, while the choice of using them is the aim of the model and solver. It is fractionable or nonfractionable: Anyway, the user can arbitrary stops the research of the optimal solution to the original MILP based on the use of a linear solver, and call one of these heuristic rules.


Order picking is often very labour intensive and its efficiency largely depends on the distance the order pickers have to travel, which therefore needs to be minimized. Selectivity ratio is equal to one for single-deep rack. The aim of this simulation is to find a set of fewer more important factors to which concentrate on during the design and control of order picking system.

In traversal policy, also called S-shape policy, the picker enters at one end of an aisle containing at least one pick and exits at the other end.

The adopted procedure for establish the definitive position of each product is the same used in the Stripes rule. Dotplot of items per cluster.

During this i,pianti she has been for all time present, spending always the right words to motivate me. These heuristic assignment procedures can significantly reduce the computational complexity of the optimization problem especially in presence of many Pods and RDCs.

Even if the percentage of density are all similar, the distribution on lndustriali matrix, so the relative correlation between products, is completely different. A significant case study is illustrated demonstrating the effectiveness of the this approach and proposed tools.
