En la actualidad, la simulación es una de las técnicas fundamentales que se utilizan para reducir el riesgo en los procesos de toma de decisiones. El objetivo principal del libro es introducir al lector en el apasionante mundo de la simulación digital de sistemas de eventos discretos, y formarlo en una metodología que es fruto de la experiencia docente e industrial de los autores. El material que se presenta es autocontenido y permite, a partir de los ejemplos prácticos que se presentan, abordar con confianza el modelado, la simulación y el análisis de procesos de fabricación, logísticos y de servicios. Tras exponer los principales conceptos relacionados con la simulación digital (...
Una obra col·lectiva importantíssima per a la història dels Països Catalans als segles XIX i XX. Conté milers de biografies de dirigents obrers i sindicals, i pel que fa al segle XIX de signataris de manifestos i documents polítics o sindicals significatius. Pel que fa al segle XX incorpora, també, tots aquells obrers que en algun moment de la seva militància varen tenir la delegació del seu partit o del seu sindicat en un congrés, conferència o assamblea representatius.

The first edition of this book was the first text to be written on the Arena software, which is a very popular simulation modeling software. What makes this text the authoritative source on Arena is that it was written by the creators of Arena themselves. The new third edition follows in the tradition of the successful first and second editions in its tutorial style (via a sequence of carefully crafted examples) and an accessible writing style. The updates include thorough coverage of the new version of the Arena software (Arena 7.01), enhanced support for Excel and Access, and updated examples to reflect the new version of software. The CD-ROM that accompanies the book contains the Academic version of the Arena software. The software features new capabilities such as model documentation, enhanced plots, file reading and writing, printing and animation symbols.
Researchers develop simulation models that emulate real-world situations. While these simulation models are simpler than the real situation, they are still quite complex and time consuming to develop. It is at this point that metamodeling can be used to help build a simulation study based on a complex model. A metamodel is a simpler, analytical model, auxiliary to the simulation model, which is used to better understand the more complex model, to test hypotheses about it, and provide a framework for improving the simulation study. The use of metamodels allows the researcher to work with a set of mathematical functions and analytical techniques to test simulations without the costly running and re-running of complex computer programs. In addition, metamodels have other advantages, and as a result they are being used in a variety of ways: model simplification, optimization, model interpretation, generalization to other models of similar systems, efficient sensitivity analysis, and the use of the metamodel's mathematical functions to answer questions about different variables within a simulation study.
