    Según la OMS, las enfermedades cardiovasculares son la causa principal de mortalidad en Europa (4 millones al año). Ante un paro cardiaco con testigos, la desfibrilación precoz, aplicada antes de transcurrir 10 minutos, puede salvar entre un 15 y un 90% de vidas según la tardanza en efectuar la desfibrilación. Por ello, la Associació Barcelona Salut propone el proyecto ¿Barcelona, ciutat cardioprotegida¿, cuyo objetivo es dotar a la ciudad de un sistema de protección ante la muerte súbita, instalando desfibriladores semiautomáticos en espacios públicos. En este marco, este trabajo se centra en la formulación de modelos de programación lineal entera mixta (MILP), para problemas de localización y cubrimiento del servicio con los objetivos: (1) minimizar el coste de instalación para alcanzar la cobertura total de un territorio urbano, y (2) maximizar la cobertura del territorio cuando se fija un presupuesto al coste de instalación.

    En una línea de montaje de productos mixtos, el tiempo requerido por una unidad de un producto en una estación no coincide con el tiempo disponible en ella (ciclo). Este trabajo se centra en el MMSP-W (Mixed Model Scheduling Problem-Work overload), un problema de secuenciación de productos en dichas líneas, y comprende: (1) las definiciones saturación estática (propia del equilibrado de la línea) y saturación dinámica (propia de la secuencia de fabricación), (2) la extensión del MMSP-W, al que se incorpora la saturación dinámica, (3) la explotación del nuevo modelo en una línea de motores, y (4) un análisis del impacto generado por la variación de la saturación dinámica máxima permitida, sobre los RRHH adicionales mínimos necesarios para eliminar la sobrecarga de trabajo (W), para una demanda y un mix de producción dados.

    A partir de tres métodos de la Ergonomía, se establece un sistema unificado de métricas para los niveles de riesgo de operaciones en líneas de producción del sector de automoción. Se define el concepto riesgo ergonómico como una función lineal dependiente de los tiempos de proceso de las operaciones y del factor de actividad aplicado por los operarios. Además, se formula un modelo matemático que incorpora como objetivo la minimización del riesgo ergonómico en problemas de equilibrado de líneas, y se explota dicho modelo a través de un caso de estudio basado en una línea de montaje de 9 tipos de motor con 140 operaciones. Tras ello, para una demanda y un mix de producción dados, se analiza el impacto generado por la variación del riesgo ergonómico máximo permitido, en cada estación de trabajo, sobre las necesidades de RRHH. Se concluye con una discusión sobre la naturaleza multiobjetivo del problema en la que se contraponen los beneficios económicos frente a los sociales.

    Resumen: El acoso moral o ¿mobbing¿ es un problema grave que constituye una lacra en el ámbito laboral con repercusiones directas en la esfera no sólo profesional sino también personal del trabajador afectado y requiere de un profundo análisis para determinar las formas de prevenirlo, combatirlo y tratarlo. El legislador hace escasamente 4 años tipificó como delito el acoso laboral, tomando conciencia que ante supuestos graves de acoso moral debía otorgarse una protección reforzada a través de la jurisdicción penal. En el presente trabajo vamos a analizar la regulación normativa y tratamiento jurisprudencial del acoso moral concluyendo con un análisis sobre las posibles lagunas existentes y la necesidad de que todos los sectores afectados, empresa y trabajador, contribuyan en la lucha contra este tipo de conductas. Abstract: Mobbing is a serious issue that constitutes a blight in the workplace with direct consequences not only in the professional field but also personal of the worker affected. Mobbing requires a thorough analysis to determine ways to prevent it, combat it, and treat it. The legislator barely four years ago classified the mobbing as a crime, being aware that in serious cases of mobbing should be given greater protection through the criminal courts. In this paper we analyze the legal normative and jurisprudence of the mobbing. We end with an analysis of the possible legal loopholes and the need for all sectors affected, the company and the workers contribute to the fight against this type of behavior.

    This document develops the doctoral thesis entitled "Modelado y resolución de problemas de secuenciación en contexto JIT/DS mediante BDP". Through a literature review we explain the problems, within the environment of the sequence problems in production systems. Then, we describe the problems under study, the MMSP-W (Mixed-Model Sequencing Problem with Work overload Minimization), the BFSP (Blocking Flow Shop Problem) and the ORV (Output Rate Variation Problem). Then, a resolution procedure based on BDP (Bounded Dynamic Programming) to solve the problems is proposed. Finally, the results of the proposed procedure are compared with others based on for example linear programming or heuristics.

    The time and space assembly line balancing problem (TSALBP) is a realistic multiobjective version of assembly line balancing industrial problems involving the joint optimization of conflicting criteria such as the cycle time, the number of stations, and the area of these stations. However, the existing problem formulation does not consider the industrial scenario where the demand of a set of mixed products is variable and uncertain. In this work we propose to introduce novel robustness functions to measure how robust the line configuration is when the production plans demand changes. These functions are based on the stations overload under future demand conditions and are used as additional a posteriori information for the non-dominated solutions found by any multiobjective optimization method. The values of the robustness functions are put together with a novel graphical representation to form a generic model that aims to offer a better picture of the robustness of the set of Pareto-optimal solutions. Real data from the assembly line and production planning of the Nissan plant of Barcelona is considered for the experimentation. This information is also employed to develop a new TSALBP instance generator (NTIGen) that can generate problem instances having industrial real-like features. The use of the robustness information model is illustrated in an experimentation formed by a set of instances generated by NTIGen. Results show how the use of this robustness information model is necessary for the decision maker as it allows her/him to discriminate between different assembly line configurations when future demand conditions vary.

    This paper presents three proposals of multiobjective memetic algorithms to solve a more realistic extension of a classical industrial problem: time and space assembly line balancing. These three proposals are, respectively, based on evolutionary computation, ant colony optimisation, and greedy randomised search procedure. Different variants of these memetic algorithms have been developed and compared in order to determine the most suitable intensification–diversification trade-off for the memetic search process. Once a preliminary study on nine well-known problem instances is accomplished with a very good performance, the proposed memetic algorithms are applied considering real-world data from a Nissan plant in Barcelona (Spain). Outstanding approximations to the pseudo-optimal non-dominated solution set were achieved for this industrial case study.

    In this paper, we present an extension to the mixed-model sequencing problem with work overload minimisation (MMSP-W) for production lines with serial workstations and parallel homogeneous processors. The extension is intended to meet the industrial need to sequence various products so that the work required and completed at the workstations over time is as constant as possible. Several approaches are proposed to formulate the problem, giving rise to different models. Four models are selected, and their performances are compared after running the Gurobi solver, using instances from the literature and a case study of the Nissan powertrain plant in Barcelona.

    We present a sequencing problem given on JIT (Just In Time) manufa c- turing env i ronments, with the objective of minimizing the variation of production rates ( ORV : Ou t put Rate Variation). We propose an extension of this problem based on t o r e quire, to the sequences, the preservation of the production mix throughout the manufa c turing of the products. To solve the ORVP (Output Rate Variation Problem) and the extended problem, we propose algorithms based on BDP ( Bounded Dynamic Progra m ming).

    Assembly lines with mixed products presents ergonomics risk that can affect to the productivity of the workers and the lines. In this work we propose to incorporate ergonomics factors to the TSALBP (Time and Space constrained Assembly Line Balancing Problems). So, we present several elements for new models to assign the tasks to a workstation considering technological, management and ergonomics factors.

    We propose a mathematical model to solve an extension to the mixed-model sequencing problem with work overload minimization (MMSP-W) for production lines with serial workstations and parallel homogeneous processors and regularizing the required workload. We performed a computational experience with a case study of the Nissan engine plant in Barcelona. © IFIP International Federation for Information Processing 2013.

    En este trabajo introducimos la aplicación de un algoritmo genético multi-objetivo basado en el NSGA-II para resolver la variante más realista del equilibrado de líneas de montaje considerando tiempo y espacio, el TSALBP-1/3. El enfoque propuesto posee una composición y diseño de componentes avanzado que le permiten generar soluciones más óptimas al problema multi-objetivo. Además este algoritmo se aplica al estudio de distintos programas de producción de la línea de montaje de motores de Nissan en Barcelona. De esta manera, se pretende realizar un análisis de los resultados del algoritmo cuando tenemos escenarios de producción-demanda variables. En particular, como afectarían las soluciones generadas a la configuración de la línea final, respecto al número de puestos y estaciones de trabajo, y respecto al área de estas estaciones.
