• Reformulation of the original bi-objective Mixed-Integer Linear Programming model as a bi-level optimization problem. Development an adapted solution tool, which is matheuristic involving Multi-Objective Evolutionary Algorithm particularly efficient for problems (SMS-EMOA) and Programming. Numerical evaluation proposed with application to design HSC in Midi-Pyrénées region (southern France), ...

In this paper, we present various functional means in the sense of convex analysis. In particular, a logarithmic mean involving convex functionals, extending the scalar one, is introduced. In the quadratic case, our functional approach implies immediately that of positive operators. Some examples, illustrating theoretical results and showing the interest of our functional approach, are discussed.

The study of linear functions is important as it provides students with their first experience of identifying and interpreting the relationship between two dependent variables. This paper, which builds on previous research, reports a study undertaken with 64, year 9 students from two Australian schools. Linear functions were introduced to these students through a graphics calculator supported, ...

In this article, we carry out a combined econometric and multiobjective analysis using data from representative sample of Andalusian schools. particular, four models are estimated in which the students’ academic performance (scores math reading, percentage students reaching certain threshold both subjects, respectively) regressed against satisfaction with different aspects teaching-learning pro...

existence of capacity drop phenomenon, as the difference between pre-queue and queue discharge flow rates, has been one of the controversial concepts of traffic engineering. several researches have focused on capacity drop existence and also its estimation issues. this paper aims to estimate capacity drop based not only on a comparison between breakdown and queue discharge flow rates, but also ...

given the strategic remarkable rank of pistachio in non-oil exports, inputs’ management in its production is so important. as the scarcest input in agricultural sector, water is considered to be among the most important inputs of pistachio production.water inadequate supply and limate conditions increase water demand in pistachio growing areas. it is necessary to determine the real value or pri...
