Table 3.

The notations, parameters, and variables of the proposed mathematical model for allocating approach.

Notations		Definition
$n=1,\dots ,N$	:	Set of suspected cases
$m=1,\dots ,M$	:	Set of medical centers
$k=1,\dots ,K$	:	Set of ambulances
$i,j=1,\dots ,N+M$	:	Set of all locations
Parameters
$T{T}_{i,j}$	:	Travel time between location i and j
$T{V}_i$	:	Visitation time of suspected case i
$T{S}_j$	:	Sanitizing time of each ambulance in CMC j
$C{M}_m$	:	The capacity of CMC m
$C{K}_k$	:	The capacity of ambulance k
Variables
$Y_{i,j,k}$	:	1, if the suspected case i transfers to CMC m by ambulance k; otherwise 0
