Abstract :This Study aims to show the impact of covid-19 pandemic on employees’ transportation in Morocco, particularly in industrial field, the daily routes between homes and workplace and vice versa. The Moroccan government is led to make strong decisions at time unexpectedly with immediate turnaround time depending on pandemic state and in function of the propagation speed of the virus and its mutated versions. And the capacity of the health ministry to hold the number of active and serious cases. These decisions should be made taking into consideration the economic situation, defining restriction to manage the pandemic situation and at the same time guarantee that the industrial activity will not be hindered of slowed. The frequency of changing the restrictions is not known and it is revealed at unexpected time which make the transportation planning a difficult task. Besides, these decisions have huge impact on transport management for both sides, companies, and service providers. The impact on transport cost centre is obvious and most of cases, the increases due to restrictions are not budgeted by companies. Through this work we will quantify the impact of distancing and capacity restriction on transport budget variating from 20% up to 96% of increase and propose a decision-making tool to plan daily routes of vehicles using a sequential coupling of vehicle routing problem (VRP) and Bin packing problem in a real case study. This tool have allowed to limit the increase of budget by optimizing the routing process, and to adapt the daily routes in function of authorities’ restrictions.
