  The conveyance of employees holds paramount significance for expansive
corporations. Employees typically commute to their workplaces either via
personal vehicles or through public transit. In this research endeavor, our
role is that of a third-party entity entrusted with orchestrating the
transportation of employees whose place of employment is situated within the
grey zone. This zone exclusively permits the ingress of electric/hybrid
vehicles and buses. We advocate for employees to adopt carpooling and furnish
bus services for those who abstain from it. The primary objective of this
research is to curtail the quantity of vehicles leased by the third-party
entity, promote carpooling among employees, amplify employee contentment, and
mitigate environmental degradation stemming from vehicular gasoline
consumption. To decipher the model delineated in this study, the epsilon
constraint method is proffered for petite-scale instances, while NSGA-II is
introduced as a potent meta-heuristic technique tailored for large-scale
scenarios. Computational trials corroborate that the models posited can be
efficaciously harnessed by enterprises to pare down transportation
expenditures.
