Using a TSP heuristic for routing order pickers in warehouses
2010
In this paper, we deal with the sequencing and routing problem of order pickers in conventional multi-parallel-aisle warehouse systems. For this NP-hard Steiner travelling salesman problem (TSP), exact algorithms only exist for warehouses with at most three cross aisles, while for other warehouse types literature provides a selection of dedicated construction heuristics. We evaluate to what extent reformulating and solving the problem as a classical TSP leads to performance improvements compared to existing dedicated heuristics. We report average savings in route distance of up to 47% when using the LKH (Lin-Kernighan-Helsgaun) TSP heuristic. Additionally, we examine if combining problem-sp…
Outlying location of logistics activities : the example of the Burgundy in France
2015
International audience; This paper contributes to the understanding of spatial location of logistics activities in an outlying region. A quantitative analysis in Burgundy (French region) underlines the important polarization of warehousing developed in a limited area during 1980–1990s intensified during 2000s. The companies that locate their warehouses in Burgundy have different strategies that could explain this outlying location. For example, the low cost of land, favorable terms of tax system and the presence of a labour pool with an important unemployed rate incentive could incentive some companies to locate their warehouses in an outlying region like the Burgundy.
The role of information and communication technologies and logistics organization in the economic performance of Sicilian fruit and vegetable enterpr…
2013
Through a direct survey conducted on a sample of firms operating in the Sicilian fruit and vegetable sector, the present study provides an empirical evidence on the degree of diffusion of ICTs as well as on relationships with the regional distribution system. To pursue this goal, a multiple regression analysis model was implemented to identify which factors affect more the economic results of fruit and vegetable enterprises. The main results of the analysis indicate that firms using specific software for accounting, warehousing, payment and sales orders and contracts, are more likely to obtain higher economic performances under the “coeteris paribus” condition, as well as firms which are eq…
Migrating from a Centralized Data Warehouse to a Decentralized Data Platform Architecture
2021
To an increasing degree, data is a driving force for digitization, and hence also a key asset for numerous companies. In many businesses, various sources of data exist, which are isolated from one another in different domains, across a heterogeneous application landscape. Well-known centralized solution technologies, such as data warehouses and data lakes, exist to integrate data into one system, but they do not always scale well. Therefore, robust and decentralized ways to manage data can provide the companies with better value give companies a competitive edge over a single central repository. In this paper, we address why and when a monolithic data storage should be decentralized for imp…
