In this paper we present a three-phase heuristic for the Capacitated Location-Routing Problem. In the first stage, we apply a GRASP followed by local search procedures to construct a bundle of solutions. In the second stage, an integer-linear program (ILP) is solved taking as input the different routes belonging to the solutions of the bundle, with the objective of constructing a new solution as a combination of these routes. In the third and final stage, the same ILP is iteratively solved by column generation to improve the solutions found during the first two stages. The last two stages are based on a new model, the location-reallocation model, which generalizes the capacitated facility location problem and the reallocation model by simultaneously locating facilities and reallocating customers to routes assigned to these facilities. Extensive computational experiments show that our method is competitive with the other heuristics found in the literature, yielding the tightest average gaps on several sets of instances and being able to improve the best known feasible solutions for some of them. © 2013 Springer Science+Business Media New York.

In this paper we present an exact algorithm for the capacitated location-routing problem (CLRP) based on cut-and-column generation. The CLRP is formulated as a set-partitioning problem that also inherits all of the known valid inequalities for the flow formulations of the CLRP. We introduce five new families of inequalities that are shown to dominate some of the cuts from the two-index formulation. The problem is solved by column generation, where the subproblem consists in finding a shortest path of minimum reduced cost under capacity constraints. We first use the two-index formulation for enumerating all of the possible subsets of depot locations that could lead to an optimal solution of cost less than or equal to a given upper bound. For each of these subsets, the corresponding multiple depot vehicle routing problem is then solved by means of column generation. The results show that we can improve the bounds found in the literature, solve to optimality some previously open instances, and improve the upper bounds on some other instances. © 2014 INFORMS.


Purpose: Knowledge management (KM) has become a key concern for companies which nowadays are constantly looking for better ways to assure knowledge sharing between their employees. However, companies encounter several challenges arising from the fact that several generations share the same workplace and a big portion of today's employees are close to retirement. This article aims to focus on knowledge sharing between generations. Design/methodology/approach: The article reviews the "generation" concept and its limitations, and introduces a new view on generations as "communities of knowledge". Findings: Companies have to find ways not only to assure knowledge transfer between generations, but also knowledge retention of the workers that are retiring. This requires a deeper understanding of the generations and their differentiated knowledge. Yet, today's dominant descriptions of generations ("baby-boomers", "generation X", "generation Y"), do not appear to adequately take into account cultural, socio-professional and individual factors. Originality/value: The proposed change of paradigm allows a deeper comprehension of nuances that may exist within the same age group. In doing so, the article makes a contribution to the understanding of knowledge sharing in organizations. © Emerald Group Publishing Limited.

Web Mining (WM) remains a relatively unknown technology. However, if used appropriately, it can be of great value to the identification of existing customers' behaviours online. The recent technical advances in the field of WM enhance tremendously the analytical Customer Relationship Management (aCRM), still usually related to a simple transactional function. This study follows an exploratory approach to assess whether WM fulfills, alone, all three objectives of the second theme of Xu and Walton's1 adapted aCRM framework for customer knowledge acquisition, namely the identification of existing web customers' behaviour. It also investigates to what extent WM should be used in conjunction with traditional marketing research to optimize CRM, and hence marketing, in a web context. In-depth, semi-structured interviews reveal that WM is very well suited to understand existing web customers' transactional web behaviour(s) (i.e. navigation patterns; amount of purchases by week, month, and region; and cross-selling and up-selling opportunities). Nevertheless, WM does not do well in understanding less obvious, underlying dimensions of customer behaviour, including how existing customers develop satisfaction, loyalty, defection and attachment on the web. WM still needs to be complemented with traditional marketing research in order to reach these more difficult but essential aCRM objectives.

In this paper we present a computational comparison of four different flow formulations for the capacitated location-routing problem. We introduce three new flow formulations for the problem, namely a two-index two-commodity flow formulation, a three-index vehicle-flow formulation and a three-index two-commodity flow formulation. We also consider an existing two-index vehicle-flow formulation and extend it by considering new families of valid inequalities and separation algorithms. We introduce new branch-and-cut algorithms for each of the formulations and compare them on a wide number of instances. Our results show that compact formulations can produce tight gaps and solve many instances quickly, whereas three-index formulations scale better in terms of computing time. © 2013 Elsevier B.V.

Organizations' dependency on information technology (IT) resources raises concerns over IT confidentiality, integrity, and availability. IT security standards (ITSS) which play a key role in IT security governance, are meant to address those concerns. It is then important for researchers, managers, and policymakers to understand the reasons for the low levels of ITSS diffusion in organizations. Building on institutional perspective, this study shows that none of the ITSS has yet reached the stage of legitimation that would prompt a widespread diffusion across organizations. Of particular focus is the benchmarking of ISO/IEC 27000 against other more diffused ISO generic standards. Three methodological approaches were used: structured documentation analysis, public secondary data analysis, and informal interviews of experts. This study sensitizes managers and policy-makers to the key role of institutional mechanisms in shaping ITSS diffusion.

In the past years, increasing efforts have been made toward the implementation of healthcare information technology with the aim of improving patient care and safety, while lowering healthcare systems' costs. However, the transition from a paper-dominant system toward a fully electronically-based system brings with it major challenges in healthcare systems. It particularly exposes healthcare providers and users to more security and privacy risks which come with the digitization of health records. Drawing on data from 1723 European hospitals, we identified, through a cluster analysis, four distinct patterns of health information technology-related security and privacy practices. We found that most European hospitals fail to implement basic security measures consistent with the use of health information technology (HIT). This study contributes to raise awareneb on HIT-related security and privacy ibues that can negatively affect healthcare users' trust and impede the effective delivery of healthcare services. An appropriate response to the HIT-related security and privacy concerns will increase the acceptability of the digitization of healthcare services.

In this article we introduce the quadratic capacitated vehicle routing problem (QCVRP) motivated by two applications in engineering and logistics: the capacitated vehicle routing problem with angle penalties (angle-CVRP) and the capacitated vehicle routing problem with reload costs (CVRP-RC). We introduce a three-index vehicle-flow formulation of the problem, which is strengthened with valid inequalities, and we derive a branchand-cut algorithm capable of providing tight lower bounds and solving small- to medium-size instances in short to moderate computing times. Furthermore, we present a hybrid metaheuristic capable of providing high quality solutions in short computing times. The two algorithms are tested on several instances from the CVRP literature modified to mimic the two problems that motivate our study. © 2015 INFORMS.

International Journal of Life Cycle Assessment | Year: 2015

Purpose: This paper presents a general impact assessment relationship, intended to contribute to the development of social life cycle analysis. This relationship and the conditions of its use are called the “Wilkinson pathway”. When used for comparisons, the pathway assesses the anticipated change in the infant mortality rate caused by a change in income distribution in the population of a country, itself generated by an important change in a life cycle. Methods: Since the 1980s, numerous authors have examined the relationship between income inequality and human health. Without formally proving so, these studies suggest that increases in inequality have negative consequences for health. First, this effect is re-examined using the most up-to-date time series data. Econometric modelling allowed calculating the coefficients of variation of infant mortality in relation to variations in income inequality for member and non-member Organisation for Economic Cooperation and Development (OECD) countries, taking into account the lag time. Then, a method to translate the effect of an important economic change in a life cycle on income distribution is proposed. Results and discussion: The econometric estimations show that a 1 % variation in income inequality leads to an approximately equivalent variation, with a lag time of about 15 years, in infant mortality in OECD member countries. The effect is two times larger than in non-OECD member countries. Together with input-output data, labour productivity and average wages in different economic sectors, this information makes it possible to quantify the probable effects of an important change in the life cycle production stage on income inequality and then infant mortality. Due to data constraints and the many assumptions made, the tools and results presented here should be used and interpreted cautiously. Above all, what is involved is a comparative method. An isolated result must not be interpreted in absolute terms. Conclusions: This work is in line with efforts to formalize general pathways allowing a comparison of socioeconomic impacts linked to various important changes in the production stage of life cycles. There are diverse prospects for improvement. A challenge for further research will be to propose methods enabling assessments of the socioeconomic impacts generated in life cycle stages other than production. © 2014, Springer-Verlag Berlin Heidelberg.
