A two-phase insertion technique of unexpected customers for a dynamic dial-a-ride problem

2006

Abstract This work deals with a dynamic dial-a-ride problem with time window constraints. In particular, new unplanned requests for service may arise at a vehicle stop and the driver must decide in real-time whether to accept or reject them. For this problem, we have developed a two-phase insertion algorithm based on route perturbations: the first phase, which is run off-line when the vehicle moves between two successive stops, aims at creating a feasible neighborhood of the current route; while the second phase, which is run in real-time every time a new request occurs, inserts, when possible, the delivery stop of the new customer in the current route.

Minimizing fleet operating costs for a container transportation company

2006

Abstract This paper focuses on a fleet management problem that arises in container trucking industry. From the container transportation company perspective, the present and future operating costs to minimize can be divided in three components: the routing costs, the resource (i.e., driver and truck) assignment costs and the container repositioning costs (i.e., the costs of restoring a given container fleet distribution over the serviced territory, as requested by the shippers that own the containers). This real-world problem has been modeled as an integer programming problem. The proposed solution approach is based on the decomposition of this problem in three simpler sub-problems associate…

New Marketing Tendencies in the Romanian Wine Industry

The nexus between big data and sustainability: an analysis of current trends and developments

2021

[EN] With the development of technological innovations, Big Data is transforming the socioeconomic world, impacting almost every organization and person. The transformations associated with the development of Big Data have important consequences for the sustainability of organizations, regions, and the society as a whole, and as such, they have been specifically addressed by the academic literature focusing on sustainability. Despite its importance, and perhaps because of its rapid emergence, there is a lack of studies dealing with the analysis of this body of literature and its trends. The current research attempts to fill this gap. The study develops a bibliometric and visualization analy…

Processus d'évaluation de l'extension de marque par le consommateur : conception et validation d'un modèle de décomposition

2004

International audience; L'objectif de cet article est de montrer qu'il existe, au-delà du transfert de valeur de la marque, un transfert de valeur dû au produit en extension dans l'évaluation de l'extension de marque. Sur la base de la confrontation de trois champs de recherche rarement associés et complémentaires, nous proposerons le recours à deux déterminants de l'évaluation de l'extension de marque : le fit association et le fit contexte. Dans le cadre d'une étude empirique dans le domaine alimentaire, nous mettrons en évidence la supériorité du pouvoir explicatif de ces indices par rapport à la typicalité ainsi que le rôle modérateur de l'expertise. Les implications de l'étude sur l'ex…

The associations of quantitative/qualitative job insecurity and well-being: The role of self-esteem.

2019

Job insecurity is recognized as one of the most prominent job stressors for employees. Despite decades of research, the concurrent examination of both quantitative (i.e. perceived threat of job loss) and qualitative (i.e., perceived threat of losing some job features) job insecurity and the analysis of their different relationships with well-being at work have received relatively scarce attention. This study examined a moderated mediation model of the relationship between quantitative job insecurity and well-being at work. In doing so, the focus was on the mediating effects of qualitative job insecurity and the moderating effects of self-esteem in the abovementioned relationships. Drawing f…

Personal use of technology at work : a literature review and a theoretical model for understanding how it affects employee job performance

2021

Employee personal use of technology at work (PUTW)—defined as employees’ activities using organisational or personal IT resources for non-work-related purposes while at work—is increasingly common in organisations. Our review of existing PUTW studies (n = 137) suggests that previous studies widely discussed PUTW outcomes, antecedents, and policies. The literature review also indicates that previous studies have proposed opposing viewpoints regarding the effect of PUTW on employee job performance, but few studies offered empirical evidence. Consequently, the conditions under which PUTW can increase or decrease employee job performance have not been discussed. We develop a theoretical model (…
