Abstract

A controller is provided to control movement of transporting devices. Embodiments limit the loads imparted on a grid of pathways structure of transporting devices to prevent non-safety-critical damage from excess loads and/or fatigue. A controller is arranged to control movement of transporting devices arranged to transport containers stored in a facility. The facility includes pathways arranged in cells to form a grid-like structure which extends in first and second directions. A route determination unit determines a route from one location to another, and a clearance unit to provide clearance for each transporting device to traverse a portion of the determined route. A constraint area determination unit determines constraint areas based on the grid-like structure and a calculation unit calculates a constraint limit in each constraint area.
