The Discrete event simulation (DES) model was designed to model in detail the operational processes of the
automotive assembly line. The processes involving material handling, body shop, paint shop and assembly line were
modeled using Arena simulation package as shown in Fig. 5.The inventory and warehousing sub-model involve processes of materials arrival rate, transporting (using forklifts) and warehousing. In this sub-model reduction of
forklift fuel consumption is the green objective. Unpacking and segregation sub-model engages the processes of
preparing material used for assembling the car. Waste minimization is the green objective for this sub-model.
