    A goal programming-discriminant function approach to the estimation of an empirical production function based on DEA results (1995)

    Notes: Abstract This paper describes a new frontier estimation procedure which relies on results obtained from Data Envelopment Analysis (DEA). The paper reviews some of the earlier works in this area and points out potential difficulties with them. It further suggests ways to validate such developments. A procedure is constructed on the basis of a Goal Programming (GP)-Discriminant Function model developed in stages during the 1980s. A numerical example is used to illustrate the proposed procedure. Then, an extensive simulation in which the GP-based procedure is compared to three regression-based techniques is presented. The simulation results clearly indicate the superiority of the proposed technique over the regression alternatives.

    Optimization Model and Algorithm for Crew Management During Airline Irregular Operations (1997)
    Springer
    Journal of combinatorial optimization 1 (1997), S. 305-321 
    Details
    ISSN: 1573-2886
    Keywords: Real-time decision support ; crew management ; multi-commodity network flow ; heuristics

    Topics: Mathematics
    Notes: Abstract Airline irregular operations have long been a realm where human experience and judgement are the most important tools to utilize. Crew management during irregular operations is usually the bottleneck of the whole system-recovering process due to complicated crew schedules and restrictive crew legalities as well as the size and scope of the hub-and-spoke networks adopted by major carriers. A system-wide multi-commodity integer network flow model and a heuristic search algorithm for the above purpose are presented and discussed in this paper. The computational experiences show that the algorithm is efficient enough to solve problems of realistic size and also has the flexibility to accommodate practical business requirements.
