Abstract
Conveyor belts are often used in conjunction with robotic arms for automated manufacturing processes. For moving and packing, the robotic arms automatically pick the items on the conveyor and place them in containers. This is however essentially a TSP, and efficiency thus requires a sophisticated control scheme. Increasing the look-ahead is a way to introduce more information to the system, however this might lead to a decreased throughput as the system waits for the perfect item and sub-par items run off or are recycled into the system. A key factor will be intelligently incorporating the look-ahead information in the constraints of the optimization problem, to limit the negative impact on throughput of the system while maintaining the benefits of the larger solution space. This paper proposes to extend the objective function to include the look-ahead and incorporating the associated time penalty in the problem constraints using a temporal-distance scoring metric. Furthermore, the decision cycle will be included in the problem formulation as it directly relates to the problems’ temporal nature.
