Examples are described relating to control of a geographical position of a mobile unit in time. In one example, a dispatch control system is provided. The dispatch control system has a data store with records of previously-attended geographical positions. These records indicate at least a duration of attendance. The dispatch control system is arranged to calculate one or more stochastic characteristics for the durations of attendance based on the records stored in the data store, the one or more measured stochastic characteristics being representative of a variability of the durations of attendance at said past geographical positions. It is also arranged to generate data indicative of an order of attendance for a mobile unit based on travel and estimated durations of attendance. This data is re-ordered and volatility metrics for each set of modified data are determined. The set of volatility metrics is used to modify the data indicative of an order of attendance for a mobile unit. In one case, volatile events are re-ordered after critical events to reduce uncertainty. The dispatch control system is configured to transmit, to the mobile unit, data indicative of geographical positions corresponding to said modified generated data. The transmitted data is for use in generating routing instructions, which, when executed by a processor associated with the mobile unit, cause navigation of the mobile unit between physical locations associated with the geographical positions corresponding to said modified generated data. |
