Plan Simulation with PDSim

This paper reports on the Planning Domain Simulation (PDSim) project, an asset for the Unity game engine to simulate plans in a 2D or 3D environment with custom animations and graphics effects. The project aims to fill a gap in the area of planning simulation and validation by tackling the problem of the scarcity of systems and tools to help the user quickly evaluate the validity of the planning model. Simulating a planning problem using 3D graphics and animation techniques can help the user to quickly evaluate the quality of a plan and improve the design of the planning domain and problem. This paper presents an overview of PDSim, including its aims as a system for automated planning, the current state of development, and future plans for the project.
