Abstract

Varying service levels during the day and complex work rules make transit scheduling a difficult task. Over the last 10 years, a joint university-S.T.C.U.M.-private enterprise effort has produced HASTUS, a comprehensive set of computer tools that assists in building cost-effective schedules. The HASTUS-Macro decision support system uses linear programming methods to estimate the costs of changes in union contracts and service levels. HASTUS-Bus employs network-flow methods to generate optimal vehicle schedules. HASTUS-Micro generates operator assignments through a combination of specially-formulated heuristics and optimal matching algorithms. Annual savings in excess of $3,000,000 (three percent of operating costs) have been reported in manpower scheduling and $1,000,000 in vehicle scheduling. This success at the S.T.C.U.M. has led to installations in nearly 40 major cities worldwide.
