Durage, S W; Wirasinghe, S C and Ruwanpura, J Y (2017) Tornado mitigation network analysis and simulation. International Journal of Disaster Resilience in the Built Environment, 8(5), pp. 478-493. ISSN 1759-5916
Abstract
Purpose: This paper aims to apply network modelling and simulation methods to critically analyse the tornado detection, warning and communication system in the Canadian Prairies. Design/methodology/approach: The simulation results of the developed network illustrate the role of collaborating partners and provide a probabilistic representation of the overall time from tornado detection to warning issuance. Furthermore, the total time from the warning issuance to when evacuation is complete is analysed by combining the time distribution of the network and the evacuation time distribution, which is developed based on survey data. Findings: A set of recommendations are offered as guidelines for consideration and possible adoption by collaborating partners who are involved at different stages of the detection, warning, communication and evacuation process. Practical implications: The research contributes to a deeper understanding of the pre-disaster phase of tornadoes by providing an overall analysis that spans different areas under the general umbrella of disaster mitigation. Social implications: This research paper helps the community to work together in developing mitigation measures to enhance social values and benefits. Originality/value: This paper shows how activity network modelling and simulation methods, which are normally applied in construction management, can be used to analyse the overall process from tornado detection to the warning issuance.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
