Comparação de dois algoritmos genéticos aplicados ao TOP

A recolha seletiva de resíduos sólidos urbanos para reciclagem é um processo dispendioso, especialmente quando realizado em grande escala. Um problema importante neste processo reside na gestão de uma frota, uma vez que atualmente as estratégias utilizadas geralmente têm baixa eficiência. O processo de recolha seletiva de resíduos sólidos urbanos pode ser modelado como um problema de encaminhamento de veículos,...

A flexible decision support tool for maintenance float systems : a simulation a...

This paper is concerned with the use of simulation as a decision support tool in maintenance systems, specifically in MFS (Maintenance Float Systems). For this purpose and due to its high complexity, in this paper the authors explore and present a way to develop a flexible MFS model, for any number of machines in the workstation, spare machines and maintenance crews, using Arena simulation language. Also in thi...

Modeling and simulating a textile production system

This paper presents a study for a production scheduling problem in a textile company, specifically in the weaving preparation area. Basically, the processing orders can be considered as sequential working steps trough three operations (charging - weaving - discharging), and the goal is to minimize time variation and to avoid delays. The machine utilization should be as higher as possible due to short delivering...

This paper is concerned with the use of simulation as a decision support tool in maintenance systems, specifically in MFS (Maintenance Float Systems). For this purpose and due to its high complexity, in this paper the authors explore and present a possible way to construct a MFS model using Arena® simulation language, where some of the most common performance measures are identified, calculated and analysed. Ne...

Simulation as a decisison support tool in maintenance float systems

This paper is concerned with the use of simulation as a decision support tool in maintenance systems, specifically in MPS (Maintenance Float Systems). For this purpose and due to its high complexity, in this paper the authors explore and present a possible way to construct a MPS model using Arena® simulation language, where some of the most common performance measures are identified, calculated and analysed.

Discrete simulation tools ranking : a commercial software packages comparison b...

This paper documents a work on all-purpose discrete event simulation tools evaluation. Selected tools must be suitable for process design (e.g. manufacturing or services industries). Rather than making specific judgements of the tools, authors, tried to measure the intensity of usage or presence in different sources, which they called "popularity". It was performed in several different ways, including occurrenc...

An activity oriented visual modelling language with automatic translation to di...

The traditional approach for discrete event simulation modelling includes visual support diagrams for modeller-client communication purposes (model interpretation and validation) and also to act as the basis for simulation lan-guage program construction. Although modern simulation packages use powerful graphical interfaces for programming and animation pur-poses, these packages still require enormous simulation...
