“…In a static layout, it is assumed that the production flow will not suffer modifications for a long period of time. The idea of a dynamic layout [15] is to take into account possible changes in the material handling flow over multiple periods.…”

Abstract-Nowadays, in order to maintain their competitiveness, manufacturing companies must adapt their production methods quickly, with minimum expenditure, to frequent variations on demand. With the shortage of the product life time, flexibility, efficiency and reusability of industrial processes are important factors, which may determine the survival of the company. The ReBORN project is working around these ideas, namely studying how can an old production equipment be reused into new contexts. The ReBORN Workbench is a simulation tool for factory layout design, which generates solutions based on the production requirements and facilities' availability, corresponding Life Cycle Assessment, and associated location cost. This paper is concerned with the ReBORN Workbench module responsible to generate solutions for equipment location, generally know as Facility Layout Problems. A Genetic Algorithm was implemented to solve these problems, which aims to minimize the total material handling costs. The effectiveness of the proposed approach is evaluated with a numerical example and compared with other similar approaches. The results show that the proposed approach is indeed effective to solve problems regarding facilities layout.

Redistribución de planta y programación de la producción: un enfoque integrado

Resumen. La preocupación principal de las empresas al realizar un proyecto de redistribución de planta es la interrupción de las operaciones de manufactura mientras se trasladan los departamentos. Este artículo presenta un modelo de optimización para programar el traslado de los departamentos y la producción, de tal manera que se garantice el cumplimiento de la demanda durante la ejecución del proyecto de redistribución de planta. Con este propósito, se planteó un modelo de programación lineal entera mixta (pem) que minimiza los costos de traslado de los departamentos, asegura el cumplimiento de la demanda y limita la duración del proyecto a un máximo establecido. Los resultados muestran que cuando la utilización promedio de la maquinaria de la planta es mayor al 60%, el proyecto de redistribución y la programación de la producción son interdependientes, por lo tanto es necesario utilizar un enfoque integrado como el propuesto en este artículo. Este se deriva del proyecto de investigación "Optimización de procesos de redistribución de planta en manufactura flexible" desarrollado en la Universidad Icesi a lo largo del periodo 2013-2014.Palabras clave: distribución de planta, redistribución de planta, optimización, programación de proyectos. Production Plant Redistribution and Scheduling: an Integrated Approachabstract. The main concern of companies when carrying out a plant redistribution project is the interruption of manufacturing operations while departments are transferred. This article presents an optimization model for scheduling the transference of departments and production, in order to guarantee fulfillment of demand during a plant redistribution project execution. For this purpose, a mixed complete linear programming model (pem from its Spanish acronym) was applied that minimizes the cost of transferring departments, ensures demand fulfillment and limits the duration of the project to an established maximum. The results show that, when average plant machinery use is greater than 60%, the redistribution project and production scheduling are interdependent, thus the need for an integrated approach such as the one proposed in this article. This is derived from the research project "Optimization of Plant Redistribution Processes in Flexible Manufacturing" ("Optimización de procesos de redistribución de planta en manufactura flexible") carried out at the Universidad Icesi in 2013-2014.Keywords: plant distribution, plant redistribution, optimization, project scheduling.

“…The design of efficient layouts and routing schemes for industrial shop floors is a well researched subject that has both practical value as well as substantial theoretical background with a broad scope (apart from solving general problems using classical approaches [18], efforts have been made to also find adaptive solutions using e.g., stochastic methods [19] and soft-computing based methods [20]). Nevertheless, many of these approaches are inaccessible to the client that wishes to establish a new shop floor (e.g., leadership of a company).…”

Abstract-Severalchallenges can arise during augmented/virtual collaboration. In this paper, we identify and classify some of these challenges from a cognitive infocommunications (CogInfoCom) point of view. The starting point of our analysis is the VirCA NET application, which was built on the Virtual Collaboration Arena (VirCA) and developed at the MTA SZTAKI. First, we demonstrate how VirCA and VirCA NET belong to the CogInfoCom paradigm and how they are also related to Future Internet. To highlight our ideas in a practical use-case, we identify key features of infocommunication in a collaborative scenario for building industrial production layouts. In the collaborative scenario, factory planning is defined as a multi-stakeholder and multi-domain challenge, which distributed planning teams have to face. Based on the features of VirCA NET and the specifics of the scenario, we outline a list of challenges, some of which are already solved by the system to some extent, and some of which remain to be solved in future work. The challenges are presented in relation to the theoretical background of CogInfoCom engines and CogInfoCom channels, in order to further strengthen the link between augmented/virtual collaboration and the goals of CogInfoCom.
