Abstract

Purpose

Complementing the importance of adequate relief supplies and transportation capacity in the first two weeks of post-disaster logistics, efficient communication, information sharing, and informed decision making play a crucial yet often underestimated role in reducing wasted material resources and loss of human life. The purpose of this paper is to provide a method of quantifying these effects.

Design/methodology/approach

A mathematical discrete dynamical system is used to model transportation of different commodities from multiple relief suppliers to disaster sites across a network of limited capacity. The physical network is overlaid with the communication network to model information delays and communication breakdowns between agents. The cost in human lives and the monetary cost are measured separately.

Findings

Simulations results highlight quantitatively how communication deficiencies and indiscriminate shipping of resources result in material convergence and shortage of urgent supplies observed in actual emergencies.

Originality/value

The model provides an example of a simple, objective, quantitative tool for decision making and training volunteer managers in the importance of a smart response protocol.

Abstract

Purpose

The need in disaster response to assess how reliably and equitably funding was accounted for and distributed is addressed by a standardized report and index applicable to any disaster type. The paper aims to discuss this issue.

Design/methodology/approach

Data from the Nepal earthquake (2015), Typhoon Haiyan (2013), the Haiti earthquake (2010), Sri Lankan flood (2011), and Hurricane Sandy (2012) illustrate uses of a public equitable allocation of resources log (PEARL). Drawing from activity-based costing and the Gini index, a PEARL spreadsheet computes absolute inequity sector by sector as well as a cumulative index. Response variations guide index value interpretation.

Findings

Index values indicates major inequity in Nepal hygiene kit distribution and Haiti earthquake (both PEARL indices near 0.5), moderate inequity for the Sri Lankan flood (index roughly 0.75) and equitable distributions for Typhoon Haiyan and Hurricane Sandy (both indices approximately 0.95). Indices are useful to approximate proportions of inequity in the total response and investigate allocation under uncertainty in sector need specification.

Originality/value

This original tool is implementable using a website containing a practice PEARL, completed examples and downloadable spreadsheet. Used across multiple sectors or for a single sector, PEARL may signal need for additional resources, correct inequitable distribution decisions, simplify administrative monitoring/assessment, and foster greater accounting transparency in summary reports. PEARL also assists historical analysis of all disaster types to determine completeness of public accounting records and equity in fund distribution.
