“…Aiming at evaluating the efficiency of various existing and new boarding strategies, we have implemented a discrete-event simulation benchmark based on the Discrete-Event System Specification (DEVS [9] and Cell-DEVS [10]) formalism. Our benchmark consists of DEVS-based models that are perfectly suitable for executing various simulations on any type of aircraft.…”

Time is crucial in the airlines industry. Among all factors contributing to an aircraft turnaround time; passenger boarding delays is the most challenging one. Airlines do not have control over the behavior of passengers; thus, focusing their effort on reducing passenger boarding time through implementing efficient boarding strategies. In this work, we attempt to use cellular Discrete-Event System Specification (Cell-DEVS) modeling and simulation to provide a comprehensive evaluation of aircraft boarding strategies. We have developed a simulation benchmark consisting of eight boarding strategies including Back-to-Front; Window Middle Aisle; Random; Zone Rotate; Reverse Pyramid; Optimal; Optimal Practical; and Efficient. Our simulation models are scalable and adaptive; providing a powerful analysis apparatus for investigating any existing or yet to be discovered boarding strategy. We explain the details of our models and present the results both visually and numerically to evaluate the eight implemented boarding strategies. We also compare our results with other studies that have used different modeling techniques; reporting nearly identical performance results. The simulations revealed that Window Middle Aisle provides the least boarding delay; with a small fraction of time difference compared to the optimal strategy. The results of this work could highly benefit the commercial airlines industry by optimizing and reducing passenger boarding delays.

“…Em Rocha [22], foram especificados os processos para a modelagem do treinamento usando Especificação de Sistemas de Eventos Discretos (DEVS) (quando o fator tempo implica em mudanças de estado) e/ou Autômato Determinístico Finito (DFA) (quando o tempo não influencia a simulação). Para a visualização e modelagem DEVS, podem ser usados: CD++ Toolkit [39] desenvolvida em C++; DE-VSJAVA [40] e JAMES II [41], ambas desenvolvidas em Java. Para a modelagem DFA, podem ser usados: Automata Editor [42]: editor para desenhar DFA, desenvolvido em C/C++; JFLAP [43]: ferramenta gráfica de edição de autômatos formais determinísticos e não determinísticos (DFA e NFA), desenvolvida em Java; Visual Automata Simulator [44]: ferramenta para simular, visualizar e editar DFA ou NFA, também desenvolvida em Java.…”

“…Moreover, it is still not possible to represent the socio-technical characteristics of an organisation. Recently there is a trend to revisit the concepts like agent-based modelling and simulation (Bonabeau, 2002;Camus et al, 2015), discrete event modelling and simulation (Wainer, 2009), and system dynamic modelling (Meadows and Wright, 2008) to nurture with socio-technical characteristics of modern organisation. Tools such as AnyLogic 1 and Simudyne 2 combine these concepts with the objective of offering a comprehensive solution.…”

Abstract:Effective decision-making of modern organisation often requires deep understanding of various aspects of organisation such as organisational goals, organisational structure, business-as-usual operational processes. The large size of the organisation, its socio-technical characteristics, and fast business dynamics make this endeavor challenging. Industry practice relies on human experts for comprehending various aspects of organisation thus making organisational decision-making a time-, effort-and intellectually-intensive endeavor. We are working on a specific instance of this problem in bespoke software development space. This paper proposes a model-based simulation approach to organisational decision-making. We illustrate how this is applied to a real life problem from software service industry.
