$($kindly use the formula provided$)..$Assume Vehicle efficiency is $95\%,$ blockage time is $10\%,$ idle time is $15\%,$ and the vehicle spends around $1$ hour charging per day. Loading operational time is $1\mathrm{.}30$ seconds, unloading operational time is $3\mathrm{.}61$ seconds, and the distance between pickup and dropoff is $4\mathrm{.}33$ m

If $12,000$ items needed to be picked up and delivered per day, how many MH Equipment is needed?

Simple Method $1$

$($travel dist.$/$velocity$)+$ empty travel time$+$ loading$/$unloading time$]/$shift

available time

$N=\frac{{\displaystyle \underset{i}{\overset{?}{}}}{\displaystyle \underset{j}{\overset{?}{}}}\frac{f_{ij}{d}_{ij}}{V}+(T_{LT})+{\displaystyle \underset{i}{\overset{?}{}}}{\displaystyle \underset{j}{\overset{?}{}}}{f}_{ij}(t_L+t_U)}{e\frac{T-t_b}{1+b+c}}$
