VAG NUREMBURG: VAG Nuremburg keeps drivers happy with better roster planning
 

Company:
 VAG Nuremburg
Sector:
 
Planning & Scheduling Scheduling Optimization


Verkehrs-Aktiengesellschaft Nuremberg (VAG) is a fully owned subsidiary of Städtische Werke Nürnberg GmbH, an agency of the city of Nuremberg. Approximately 1,800 employees ensure the smooth running of public transport, comprising nearly 400 private buses, trams and subway trains in Nuremberg and the adjacent regions, as well as in the neighboring cities of Fürth and Erlangen. Some 870 drivers cover a daily distance of approximately 80,000 km.

Business need:
Verkehrs-Aktiengesellschaft (VAG), responsible for operating public transport in Nuremburg, wanted to make its driver scheduling more efficient while taking into account the individual drivers’ preferences. The objective was to improve VAG’s competitive position through lower costs and yet increase the attractiveness of the workplace for drivers. Conventional scheduling methods were unable to cope with the operational variety and complexity.

Solution:
By using the IBM® ILOG® CPLEX® Optimization Studio, VAG can create cost-effective scheduling while largely taking into account the individual preferences of hundreds of employees. The solution enables compliance with many other regulations, and minimizes operational costs.

Benefits:
Reduces labour costs by reducing deviation from the contractually-agreed working time by about 60 percent. Minimises costly unplanned overtime by up to 70 percent. Takes up to 80 percent of individual driver preferences into account, increasing the attractiveness of the workplace. Reduces manual rescheduling by about 25 percent, reducing dispatchers’ workload.
