A Proposal of Consumer Driven Framework for Enabling Sustainable Production and Consumption

Sustainability becomes the key towards success of manufacturing industries now. Besides increasing efficiency of sustainable industrial processes, sustainable consumption becomes an important complementary strategy for making economies more sustainable gradually. Hence, the research in sustainable production and consumption (SPaC) keeps emerging and the approach of information transition became noticed as the key to promote SPaC. Therefore, there is a notable need for generating proper approach in order to achieve the goal of providing sustainable information of a product for consumers has been discussed.

MEJORA DEL TRÁFICO FERROVIARIO MEDIANTE PROGRAMACIÓN LINEAL

La gestion de los sistemas ferroviarios plantea problemas de diferente alcance. Uno de ellos se refiere a la determinacion del numero de unidades de transporte necesarias para atender un conjunto de trayectos, definidos por sus respectivos origenes y destinos y por las horas de partida y de llegada. Alternativamente, puede resultar interesante determinar como gestionar un determinado conjunto de unidades de transporte para atender dicha demanda haciendo el uso mas eficiente de aquellas. En este articulo se presenta un modelo de Programacion Lineal Entera para atender estos problemas. En particular, se describe un caso de estudio correspondiente a una de las lineas de la red de Cercanias de la region de Madrid

PROBLEMA DE PLANIFICACIÓN ESTRATÉGICA DE PERSONAL PARA CUBRIR UNA DEMANDA DE CARGA DE TRABAJO TEMPORAL VARIABLE

Staffs are frequently dimensioned to attend a given workload demand, which is highly variable over time. For example, providing services for planes while parked is characterized by a great variability in terms of the required work load, due to the time dispersion of arrivals and departures. This turns the task of staff dimensioning into a complex and critical one, since the associated cost highly impacts the profit and loss account of the company. In this paper we present a highly configurable model that we solve using Linear Programming, which allows to obtain optimal result for large numbers of workers. It can be of use for a large number of industries. In particular, we describe an example where the impact is assessed in economic terms.
