Custom A* navigation process flow for collision avoidance

Hi everyone,


I'm trying to control many robots that travel (only in straight lines) within the bounds of a grid and must reach certain destinations without colliding against each other.


Outside the context of Flexsim, I would use an A* algorithm that calculates the path of each robot sequentially and a sort of time-based reservation system for nodes that are currently a part of the robot's paths. As a robot finishes it's path segment those nodes will be available for future paths.


I understand Flexsim has A* built in, which is amazing, but does not account for acceleration and deceleration, which is a requirement of mine.


How would one go about doing this using process flow, or is there a simpler solution I'm not aware of?


Thanks in advance. This is a great community.
