VIEW ABSTRACT In this research we applied a reinforcement learning algorithm to find set of routes from a depot to the set of customers while also considering the capacity of the vehicles, in order to reduce the cost of transportation of goods and services. The Vehicle Routing Problem As anticipated at the beginning of the chapter, the VRP is a typical distribution and transport problem, which consists of optimizing the use of a set of vehicles with limited capacity to pick up and deliver goods or people to geographically distributed stations. The next chapter, chapter 2, provides a concise introduction to the vehicle routing problem and solution methods. By minimizing the cost and environmental impact, we have the setting for mathematical problem called the vehicle routing problem with time windows. at each point in time the agent performs an action and the environment generates an observation and an instantaneous cost, according to … In Advances in Neural Information Processing Systems, pp. We have been building on the recent work from the above mentioned papers to solve more complex (and hence more realistic) versions of the capacitated vehicle routing problem, supply chain optimization problems, and other related optimization problems. This problem is one of the NP-hard problems and for this reason many approximate algorithms have been designed for solving it.
