Question $2$:

a$)$ Emergency Response Center $($ERC$)$ considers using motorcycles right after an

earthquake in order to have an idea about the status of districts in Bak$$rk$$y after the

earthquake within $2$ hour time. According to plan, each node should be visited by a

motorcycle right after the earthquake. Assume the motorcycles are located in ERC $($node

#$1$ of the data set$)$ and they can travel $30k\frac{m}{h}$ on the average. Find the minimum

number of motorcycles to be used. Report the routes for each motorcycle.

b$)$ Now conduct a sensitivity analysis on part a$.$ Decrease the total visit time from $2$ hours

to $1$ hour with increments $0\mathrm{.}25hrs.$ Note the # of motorcycles required for each step.

c$)$ Now we want to relocate the ERC. Among the distribution centers that you open in Q$1$

part a$,$ where do you move ERC. Use the number of motorcycles that you have found

in part a$.$

d$)$ Now assume we can locate the motorcycles in more than one DC$\text{'}$s$.($Still you will

choose the motorcycle locations from Q$1$ part a$)$ How many motorcycles should locate

in which DC$\text{'}$s$,$ in order to visit all districts in $1$ hour this time?
