Therefore, the overall aim of the thesis is firstly to provide analytical models, integrated approaches, and present some original tools to support the design and control of whole distribution logistics network according to three different planning levels i. Products are retrieved from one side of the rack and refills are done from the other side. A heuristic approach can be applied to obtain good and feasible solutions. Sometimes, dedicated storage can be useful if products have different weights.
Chapter 2 presents an innovative hierarchical framework for the development of new modeling approaches to the strategic, tactical, and operational decision problem.

The residual demand of the selected customer is assigned to the RDC as much as possible. Case study40 Figure 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 Cluster Analysis and similarity based heuristic clustering algorithms as proposed by Statistics and properly modified by the authors to support apreschi decisions of logistic managers. The crane mechanically stops in front of the correct pick location and waits for the order picker to execute the pick.
Furthermore, literature argue widely on low-level forward reserve order picking system thus lacking in system where the forward pick area is spread over several higher levels. The industrialu analysis is based on different simulated scenarios. Plot of savings ref. MILP model, mono period, multi product, capacitated, multi mode OR Heuristic rules for the 3 rd stage Heuristic rules for the 3 rd stage Heuristic rules for the 3 rd stage A – Strategic planning Optimal solution to the original model Optimal solution to the simplified model A s o f t w arirgo r e t o o l 55 Figure 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, Without explaining anything, without telling you where, there will always be a sea, which will call you.
Cristina Mora, two essential members of the crew always ready to grab me off the water when in need and dispense impressive advices.
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. A systematic approach for the order picking problem using product correlation According to the complementary-based principle previously illustrated, an approach for the correlated assignment storage has been developed for the present research.
Classification of order-picking systems based on De Koster It can be distinguished two types of picker-to-parts systems: The organization and operational policies include mainly five factors: The generic instance of this model can be made of thousands of variables, a large part of them boolean or integer. About four hundred orders are generated randomly by a computer.
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 see Figure Several heuristics and algorithms have been proposed and compared in the literature Nidustriali and Aase ; Hwang et al.
Goods must be unpacked, sorted, stored, repacked, and sent out to their correct destinations.

Therefore, seen from the distribution of order lines, batch picking may not be appropriate for the operation but single order picking may be suitable. The number of DCs is generally limited to a few, e. Figure 56 shows the picking equipment. From the main effect plot for total travel parecshi and the interaction plot for total travel time it can be seen that: Another way to store several pallets behind each other is the so called drive-in or drive-through racks.
Finally the goal of this thesis is to present a set of advanced models and tools for the design and control of an integrated supply chain. The nn algorithm is based on industrial scheme that erases rows and columns in a similarity matrix as old clusters are merged into new ones. Each cluster is assigned to a vehicle and defines a vehicle trip, i.
This rule inserts the clusters in the list by starting from those with minimal power equal to 1 and then following an ascending order of power. This planning is multi period and the duration of the planning horizon of time is generally 3 months or 1 year. Strategic flows at the third stage
