MAINTENANCE PLANNING AND CONTROL SYSTEMS

SL, the public transport authority for Stockholm and its suburbs, operates 1800 buses. Cost reductions have been achieved by standardizing bus types and by improving and decentralizing maintenance operations. The BUP management information system has improved the planning and supervision of maintenance and enhanced the control of spare parts. All these steps have reduced life-cycle costs. Formerly 50% of total maintenance, including all major overhauls, took place in a single central maintenance facility. That shop has been closed and work is now done in the five districts, each of which became responsible for all levels of maintenance on buses assigned to them. One shop in each district does the heavy repair. A computerized on-line management information system now accumulates data on mileage, performance and costs. Identifiable annual savings of $700,000 are yielded by the management system: many other benefits are not quantifiable. The spare parts system has been automated. Components of the computer file include vehicle register, mileage calculation, maintenance history, preventive maintenance planning, payroll with piece work, productivity checking, staff levels, budget calculation, warranty data, thests and postponed repairing. Further enhancements are in the planning stage.
