Abstract: A system controls orders and deliveries of products such as pre-mixed concrete deliveries in urban areas. A data matrix concerning product particulars, orders and progress towards delivery is built and utilized to control, for example, a fleet of delivery vehicles where a co-ordinated delivery of batches at suitably timed intervals is required. Vehicle position reporting and delivery status is used together with information on travel times and updated customer orders and variation in orders. The information stored permits accurate and efficient customer billing and sub-contractor management and accountancy.
