“…Research on aircraft line maintenance focuses on capacity buffers. In coping with uncertainty while pursuing effectiveness, airlines combine robustness of planning (Ahmed & Poojari, 2008), and responsiveness of execution (Callewaert, Verhagen, & Curran, 2018). Buffer management is almost exclusively viewed as a resource allocation or capacity problem.…”

Based on a multi‐year research engagement with practice, we present a novel solution design for frontlog scheduling in aircraft line maintenance and offer theoretical insights into buffer management in operations. The field problem of the case airline was to improve departure reliability for long‐haul aircraft without increasing maintenance resources, and without using backup aircraft. Frontlog scheduling is the purposeful introduction of over‐maintenance as a buffer of maintenance tasks that can be opportunistically postponed. A detailed simulation of the solution introduced in the airline's operations indicates a performance frontier shift, concurrently improving departure reliability, and reducing maintenance cost. We position the novel practice in operations and maintenance management literature, arguing that the frontlog creates a new type of time buffer, available in contexts where capacity serves predictable as well as unpredictable demand. Further theoretical elaboration leads us to reconceptualize buffer management along time and capacity dimensions, reducing inventory to a special case of time buffering.

“…The airline planning process is typically decomposed into four subproblems: schedule generation, fleet assignment, maintenance routing, and crew scheduling. 16 The objective of schedule generation is to determine origin-destination itineraries, frequencies, and times to fly in a given period of time. The fleet assignment problem determines which type of aircraft should be assigned to each flight.…”

This paper provides an overview of the key contributions within the planning and scheduling communities with specific emphasis on uncertainty analysis. As opposed to focusing in one particular industry, several independent sectors have been reviewed in order to find commonalities and potential avenues for future interdisciplinary collaborations. The objectives and physical constraints present within the planning and scheduling problems may vary greatly from one sector to another; however, all problems share the common attribute of needing to model parameter uncertainty in an explicit manner. It will be demonstrated through the literature review that two-stage stochastic programming, parametric programming, fuzzy programming, chance constraint programming, robust optimization techniques, conditional value-at-risk, and other risk mitigation procedures have found widespread application within all of the analyzed sectors. This review is the first work which attempts to provide a comprehensive description of the advances and future directions for planning and scheduling under uncertainty within a variety of sectors.
