AntPlan is a new generation software tool for real time planning and simulation of industrial production. All production stages can be optimised, monitored and controlled, and simulated in order to rapidly increase its performance. It can be either used as an automated planner, fully integrated in the production process, or as a support tool to assist decision making at the management level. AntPlan can optimize production thanks to an advanced scheduling algorithm, which can also handle unexpected events (new orders, unprogrammed maintenance, breakdowns) within a few seconds of computation. AntPlan offers a wide array of visualisation options, including Gantt charts. AntPlan can also simulate alternative production scenarios, in order to define plans that are efficient and robust.
