Hi friends,
I hope that everyone are healthy.
I'm trying to model a truck flow to a new estimate to a bid.
In a construction, I have many trucks with many materials to be delivered ( gravel, sand, concrete, asphalt and so on) coming and going every day for ten hours shift, but I have only one guardhouse to controle this flow, this is a main constraint of my schedule, because fatally we will have a bottleneck because of this. Each truck takes 5min to pass on guardhouse, so we only have 12 trucks per hour at maximum flow, no more. Based on the brief above, does anyone have a model with a similar situation, to help me? I can't find a valid solution to this model. The construction is an airport and usually has many restrictions to get in on the site. Best regards, Daniel Morais
