eng Optimal Scheduling of Vehicles for Wheelchair Users in Public Transport Public transportation operates on the network according to the given timetable. I.e. the set of regular vehicle journeys is given. Each journey is determined by vertices it passes and by departure and arrival times. However, only a minor part of vehicles are wheelchair friendly (abb. WFV). During one day, a WFV can be assigned to a sequence of journeys called a daily duty of the WFV. The demand of a WCU is called covered by a WCV journey without transfer, if a WCV is assigned to the journey and the journey connects the origin and the destina-tion of the WCU in the demanded time. It is called covered by a pair of WCV jour-neys with one transfer if the first journey of the pair connects the origin of the WCU with the transfer stop and the second journey of the pair connects the transfer stop with the destination of the WCU, both in the demanded time. The problem P1 is to find the minimum set of VCV daily duties covering the de-mand of all WCU’s. If such a solution does not exist, then the problem P2 is to find such a set of daily duties of all VCV’S that it covers the demand of maximal num-ber of WCU’s. The paper proposes heuristic methods for the solution of problems P1 and P2 wheelchair user; wheelchair user friendly vehicles; public transport; optimization; method
