An emergency dispatch model considering the urgency of the requirement for reliefs in different disaster areas
Abstract: Frequent
sudden-onset disasters which have threatened the survival of human and the
development of society force the public to pay an increasing attention to
emergency management. A challenging task in the process of emergency management
is emergency dispatch of reliefs. An emergency dispatch model considering the
urgency of the requirement for reliefs in different disaster areas is proposed
in this paper to dispatch reliefs reasonably and reduce the effect of
sudden-onset disasters.
Design/methodology/approach: Firstly, quantitative assessment on the
urgency of the requirement for reliefs in different disaster areas is done by
an evaluation method based on Fuzzy Comprehensive Evaluation and improved
Evidence Reasoning which is proposed in this paper. And then based the
quantitative results, an emergency dispatch model aiming to minimize the
response time, the distribution cost and the unsatisfied rate of the
requirement for reliefs is proposed, which reflects the requests of disaster
areas under emergency, including the urgency of requirement, the economy of
distribution and the equity of allocation. Finally, the Genetic Algorithm is
improved based on the adaptive crossover and mutation probability function to
solve the emergency dispatch model.
Findings and Originality/value: A case that the Y hydraulic power
enterprise carries on emergency dispatch of reliefs under continuous
sudden-onset heavy rain is given to illustrate the availability of the
emergency dispatch model proposed in this paper. The results show that the
emergency dispatch model meets the distribution priority requirement of
disaster area with the higher urgency, so that
reliefs are supplied more timely.
Research limitations/implications: The emergency dispatch model faced to
large scale sudden-onset disasters is complex. The quantity of reliefs that
disaster area requires and the running time of vehicles are viewed as available
information, and the problem that how to obtain the information is not
considered.
Practical implications: The emergency dispatch model considering the
urgency of the requirement for reliefs in different disaster areas is
applicable to a realistic emergency dispatch of reliefs under sudden-onset
disasters and the research results is the foundation of further research on the
problem of emergency management.
Originality/value: This paper proposes emergency dispatch model
considering the urgency of the requirement for reliefs in different disaster
areas which can meet the realistic requirement that the disaster area with the
higher urgency has an priority to obtain the reliefs and make reliefs be
distributed timely.
