The urban waste collection is one of the major municipal activities that involves large expenditures and difficult operational problems. Also, waste collection and disposal have high expenses such as investment cost (i.e. vehicles fleet) and high operational cost (i.e. fuel, maintenance). In fact, making slight improvements in this issue lead to a huge saving in municipal consumption. Some inci...

Haplotype Inference is a challenging problem in bioinformatics that consists in inferring the basic genetic constitution of diploid organisms on the basis of their genotype. This information allows researchers to perform association studies for the genetic variants involved in diseases and the individual responses to therapeutic agents. A notable approach to the problem is to encode it as a com...

This work arises from the research of the Metaheuristics Network on the University Course Timetabling Problem. In a first phase straightforward implementations of different metaheuristics were compared on a common local search framework [4]. In a second phase problem specific knoweldge was exploited and several alternatives for local search and metaheuristics were considered. Many possibilities...

The unrelated parallel machine scheduling problem aims to assign jobs independent machines with sequence-dependent setup times so that the makespan is minimized. When many practical considerations are introduced, solving resulting challenging, especially when problems of realistic sizes interest. In this study, in addition conventional objective minimizing makespan, we further consider burn-in ...

Hybridizing metaheuristic approaches becomes a common way to improve the efficiency of optimization methods. Many hybridizations deal with the combination of several optimization methods. In this paper we are interested in another type of hybridization, where datamining approaches are combined within an optimization process. Hence, we propose to study the interest of combining metaheuristics an...

This paper focuses on optimizing the long- and short-term planning of perishable product supply chain network (PPSCN). It addresses integration strategic location, tactical inventory, operational routing decisions. Additionally, it takes into consideration specific characteristics products, including their shelf life, inventory management, transportation damages. The main objective is to minimi...
