We are trying to create a vehicle routing problem in which we must arrive at order locations within a set time period. Basically we are attempting to deliver pizzas within a timeframe of 30 minutes from an order time. We assume a 15 minute service time (order time to pizza in delivery car). We set the violation time to 0 to find out how many pizzas can be successfully delivered. When we run the network analysis and look at the time log, we notice that pizzas are arriving at delivery points before they have actually been ordered. We figure there must be a way around this? Thanks so much for your help!
Yes, we have read the help section but it doesn't seem to address our exact problem. We need the pizzas to not be able to be picked up from a depot until they have been ordered and made. We can't figure out how to get the network analyst to understand this essential part. We would ideally have a fifteen minute service time at the depot and a two minute service time at individual houses. We can't seem to find other people who have experienced this problem. Thanks! George
You can use the paired order to set it up. Basically, you�??ll need to create a pair order where the first order has a time window with the start time set to �??pizza order time�?� and end time set to empty, also set the service time for the first order to 15 minutes. The second order should have a time window [pizza order time, pizza order time + 30 minutes] and a service time of 2 minutes. The MaxViolationTime1 of second order should be set to zero. These time windows will guarantee pizza to be delivered after it is well done.
