Synchronized dial-a-ride transportation of disabled passengers at airports

A memetic algorithm for the patient transportation problem

“…DARP addresses passenger transportation, and thus service quality must be taken into account. DARP usually arises in contexts in which passengers cannot easily use the regular public transportation system, e.g., rural areas [54,15], airports [43], and the health-care context [44,31,19,7]. Most of the DARP literature is derived from real-world applications, and accordingly the problem definitions usually differ slightly.…”

Demand Responsive Service-based Optimization on Flexible Routes and Departure Time of Community Shuttles

“…The impact of D r 0 on the sum of C k,r I and C k,r P12 of all the requests on route r can be obtained by Equation (18).…”

“…DARP is a variant of PDP in which the loads to be transported represent people. DARPs are always motivated by various real-life applications, such as offering services for elderly or disabled people [16,17], providing dedicated transportation to airports [18] or hospitals [19] and customized bus service design [20]. For example, Detti et al in 2017 addressed a multi-depot dial-a-ride problem arising from a real-world healthcare application with the consideration of serval constraints such as heterogeneous vehicles, vehicle-patient compatibility, quality of service requirements, patients' preferences, tariffs depending on the vehicles' waiting [19].…”

“…the in-vehicle cost and some penalties incurred by unsatisfactory service) and the service provider's operating costs (e.g. the total vehicle travel distance and the number of required vehicles) (see [17][18][19][20]). Some realistic constraints with regard to these two aspects, such as the service time window and maximum route duration, are usually considered in DARPs.…”
