Exact solution of the soft-clustered vehicle-routing problem

2020

Abstract The soft-clustered vehicle-routing problem (SoftCluVRP) extends the classical capacitated vehicle-routing problem by one additional constraint: The customers are partitioned into clusters and feasible routes must respect the soft-cluster constraint, that is, all customers of the same cluster must be served by the same vehicle. In this article, we design and analyze different branch-and-price algorithms for the exact solution of the SoftCluVRP. The algorithms differ in the way the column-generation subproblem, a variant of the shortest-path problem with resource constraints (SPPRC), is solved. The standard approach for SPPRCs is based on dynamic-programming labeling algorithms. We s…

Cimo: An efficient 2-phases calculator of multimodal itineraries for real trans-territories based on a dynamic programming

2015

In this work we propose an exact solution for calculating multimodal itinerary. This solution is named Cimo (Calculateur d'Itineraires Multimodaux Ordonnes). Cimo is an exact optimal itineraries' calculator wherein itineraries are sorted, multimodal, and trans-territorial. The solution is based on a dynamic programming algorithm "cut", "price" and "share". This solution is multi-objectives and multi-constraints. Several versions of this algorithm are proposed following a methodological approach that enables evaluation of efficiency and complexity's gain : through theoretical calculus and benchmarks. In the first version of realistic problem, we propose a solution with itineraries calculated…

Videogames and Inclusive Education project in Palermo Secondary School

2017

Attempting to support videogames for education and learning purposes has prompted considerable attention over the last years. The great variety of digital games available has provided much for educators and researchers to explore, resulting in intense disputes that many games have benefits both in and out of the classroom for learners of secondary school. Many games have been revealed as strong educational tools for their design as well as their effective implementation in the classroom. Thus far, research on the impact and outcomes of this pedagogy is somewhat limited, but promising. Further projects and evaluations are required to provide the support needed in order to encourage more teac…

Examining the role of religion in a family setting: religious attitudes and quality of life among parents and their adolescent children

2016

The study examined the role of religion in a family setting by evaluating relationships between religious attitudes and quality of life among parents and their adolescent children. Previous research suggested that religious beliefs and behavior play an important role in shaping family relations and their members’ well-being. The group of 465 parents and adolescents completed four scales measuring religiousness, quality of life, and satisfaction with life. Results using correlational analyses and cluster comparisons showed that religiousness had a significant effect on both subjective quality of life dimensions and satisfaction with life among parents and adolescents. Individuals characteriz…

Book Clubs and Book Commerce

2019

In the twentieth century, cumulative millions of readers received books by mail from clubs like the Book-of-the-Month Club, the Book Society or Bertelsmann Club. This Element offers an introduction to book clubs as a distribution channel and cultural phenomenon, and shows that book clubs and book commerce are linked inextricably. It argues that a global perspective is necessary to understand the cultural and economic impact of book clubs in the twentieth and into the twenty-first century. It also explores central reasons for book club membership, condensing them into four succinct categories: convenience, community, concession and, most importantly, curation. This title is also available as…
