System dynamics for humanitarian operations revisited

Abstract

PurposeThe purpose of this study is to show that the current complexity of humanitarian operations has only increased the usefulness of system dynamics (SD) in helping decision-makers better understand the challenges they face.Design/methodology/approachA critical analysis to evaluate how SD methodology has been applied to humanitarian operations.FindingsToday's humanitarian operations are characterized by huge complexity given the increased number of stakeholders, feedback loops, uncertainty, scarce resources and multiple objectives. The authors argue that SD's tools (causal-loop diagram, data layer, simulation model) have the capacity to appropriately capture this complexity, thereby enhancing intuition and understanding.Originality/valueResearchers and practitioners hesitate to use system dynamics when data is missing. The authors suggest alternatives to deal with this common situation.
