Optimization of Multi-Objective Mobile Emergency Material Allocation for Sudden Disasters

Abstract

The mobile emergency system is a new emergency mode that provides a solution to deal with increasingly frequent sudden disasters by reasonably allocating mobile emergency facilities and optimizing the allocation of mobile emergency materials. We consider mobile emergency cost and mobile emergency time as two objective functions. This paper establishes a multi-objective mobile emergency material allocation model, and transforms the multi-objective. We choose the emergency material transportation path for coding, and apply the hybrid leapfrog algorithm for material allocation to obtain the optimal solution. Finally, the feasibility of the model is verified by taking Zhengzhou urban area under the “21.7” severe rainstorm and flood disaster in Henan Province. The result analyses show that the model can correspond to each stage of mobile emergency material allocation based on the value of cost preference, and put forward suggestions on the location of mobile emergency facilities and the amount of material allocation.

Scheduling Optimization of Mobile Emergency Vehicles Considering Dual Uncertainties

“…Moreover, the particular risk of each sudden disaster will affect the decision preference of the mobile emergency vehicle scheduling model. With reference to the modeling processes by Bozorgi [1] and Li [22], the overall scheduling factors of mobile emergency vehicles from the emergency center to the disaster area are explored based on Section 2.1.…”

Robust Appointment Scheduling in Healthcare

“…They assigned their scheduled arrival times to reduce the anticipated total waiting time and used a chance constraint to limit the likelihood of the server over time given a sequence of appointments arriving at a particular server. A systematic literature review for no-shows in appointment scheduling and the application of robust optimization in heath appointment other domains can be seen in [24][25][26][27][28][29][30][31][32][33]. Wang et al [34] presented a multistation network model that carefully established a compromise between assumptions that permitted tractability and assumptions that prevented real-world adoption.…”

Research on the construction of a “full-chain” rapid response system for power emergencies

“…Li proposed measures such as improving the emergency plan system, perfecting the emergency protection work, conducting regular drills, and performing the emergency assessment to put power emergency management into practice [ 23 ]. To ensure the reasonable dispatching of emergency materials, Li et al built a multi-objective mobile emergency material allocation model based on the affected area's emergency material demand, solving the optimal solution of the electric power emergency material deployment path to decrease the cost of emergency material dispatching [ 24 ]. These initiatives, while providing theoretical references for reacting to various forms of emergencies, do not concretize the electric power emergency management system or establish more refined emergency disposal units.…”
