A short-term flight scheduling model for air express carriers is developed to determine suitable routes and flight schedules with the objective of minimizing operating costs, subject to related operating constraints. The model is formulated as an integer multiple commodity network flow problem...

In this research we combine airport selection, fleet routing and timetable setting to develop an integrated scheduling model. The objective is to maximize operating profit, given the related operating constraints. The model is formulated as a mixed integer program that is characterized as...

Four strategic models, combining different manpower supply principles, flexible management strategies and related operating constraints, are developed to help an air cargo terminal manage its long-term manpower supply more effectively. The models are formulated as integer/mixed integer linear...

In this research we develop an integer programming model to assist airport authorities to assign common use check-in counters. Due to the many complicated factors that have to be considered in such a model, the problem size is expected to be huge, making its solution difficult and therefore not...

Human hazards can represent a significant risk to the population and cause huge economic damage in many urbanized regions. In order to be able to identify risk hot spots and implement targeted risk reduction measures, decision makers need to have a clear picture of the risk situation in their...

A robust and reliable risk assessment procedure for the determination of transportation hazards between Taiwan and China needs to be developed. These hazards, which are related to mixed types of transport, including both air and maritime routes, play an important role in public security, and...
