Aggregate and ready mix companies are improving fleet efficiency and customer service by switching from manual to computerized dispatch systems. There are several features producers should consider when selecting a system: automatic calculation of travel and washout time; truck demand display; job scheduling capabilities; real-time truck tracking displays; problems displayed on-screen; and automatic invoicing so order information can be used by the accounting department without additional clerical work. Companies that have gone to computerized dispatching are learning that it can be a powerful tool for increasing productivity and reducing operating costs.
