In companies where lean management is deployed successfully and in which production work is planned and organised meticulously, there is a place for everything and everything is in its place. However, in practice, it is not uncommon for the wrong material to end up in the wrong place at the wrong time, despite all materials, boxes, workplaces, feeder belts and so on being labelled. As a consequence, production processes are interrupted or errors are made in production or assembly. Although having an effective Kanban management system in place can control the time at which a material finds itself in a specific location, this does not absolutely guarantee process reliability. The use of an AGV system can significantly increase process reliability, as the AGV is able to complete a defined process without errors and can thus be relied upon to safeguard the transportation of goods (and therefore the process itself) between different locations. With predecessor solutions, intelligence and the assurance of process reliability were in human hands due to the absence of automated checks and controls to determine if the right material was in the right place at the right time. Monitoring the process is the only way to guarantee absolute process reliability.
