Ceder and Stern (1984) addressed the problem with an integer programming formulation and heuristic person-computer interactive procedure. The latter approach focuses on reconstructing timetables when the available vehicle fleet is restricted. Public transport timetable is commonly constructed for given sets of derived frequencies. The basic criteria for the determination of frequencies are: (a) to provide adequate vehicle's space to meet passenger demand, and (b) to assure a minimum frequency (maximum-policy headway) of service.
3 •o 0> I Figure 7. 5 Advanced Modeling for Transit Operations and Service Planning Shifting Departure Times with Given Tolerances Another factor considered in a manually produced public transport schedule is related to the shifting of trip departure times. A general description of a technique to reduce the fleet size for a variable departure time scheduling problem can be found in Gerstbach and Stern (1978). This technique for job schedule utilizes the deficit function representation as a guide for local minimization in maximal intervals, M"VueT .
This >el \' 2\ function represents the number of trips simultaneously in operation. Initially, the lower bound was determined to be the maximum number of trips in a given timetable that are in simultaneous operation over the schedule horizon. Stem and Ceder (1983) improved this lower bound, to G(S') > G (S) based on the construction of a temporary 48 Advanced Modeling for Transit Operations and Service Planning timetable, S', in which each trips is extended to include potential linkages reflected by DH time consideration in S.
