System Dynamics Model for Airport Characterization in Hub-and-spoke Networks

Abstract

Global revenue by passenger kilometers over the last ten years has grown at an average of 4.7 percent per year. The high growth of air transport must be offset by equivalent airport investment: perhaps even a doubling of the percentage growth of numbers of passengers. The purpose of this paper is to build a development model for investment in hub-and-spoke airport networks. The methodology developed in this paper uses systems dynamics theory. The benefit of using this approach is that the variables in the model are determined through a systems thinking process; the determination of variables through such a thinking process considers causality between variables dynamically, logically, and realistically within a complex aviation industry system. The simulation model shows that using a system dynamics approach can be used to simulate airport infrastructure investment development in a hub-and-spoke network. One of the subsystems is congestion; the result of simulation of this subsystem yields the behavioral characteristics, which show that a surge in demand (which is then offset by the provision of capacity or capacity enlargement) will eventually become stable, indicated by a lack of lines on the runway side. This means that decreases in congestion will increase passenger demand, and will also enhance potential investment in airport infrastructure.

System Dynamic Approach to Improve Emergency Response in Humanitarian Logistics in Indonesia

“…This study's first step is the concepttualization stage, where material and information flow on the current replenishment system is described. The flow of material and information should be described first to be the basis of this research to build the current system model known as problem structuring [16]. After the expert verifies the problem structure model, the data is collected, and a causal loop diagram is built [16] to guide the real-world problem situation [20].…”

A stock and flow diagram is built on the formulation stage to apply system thinking ideas in the model, as suggested in Senge [21].…”

“…Bimantino [14] stated that system dynamics is a method to study some feedback scheme from a complex system. The used system dynamic simulation to understand the behavior of systems had been applied to several studies: IOT infrastructure in pharmacy industry [15], salacca-pondoh's business [14], airport characterization in hub-and-spoke networks [16]. Besiou et al [17] had managed to use system dynamics for modeling humanitarian logistics.…”

Value Increase of Jetty Project Based on System Dynamics

“…Systems Dynamics Methodology was first introduced by Jay Forrester from MIT (Massachusetts Institute of Technology) in the 1950s [16], [17]. In this scope of the study, the system is defined as a collection of elements that continuously interact over time to form a unified whole.…”

Evaluating Impacts of Overweight in Road Freight Transportation: A Case Study in Brazil with System Dynamics

“…The existence of multiple interacting feedbacks means it is difficult to hold other aspects of the system constant to isolate the effect of the variable of interest. Therefore, SD is a method that studies the changes in the behavior of a system over time to assess impacts of decision making at a strategic level [22][23][24][25].…”
