Typically international airports have features quite distinct from those of regional airports. We discuss the process of developing a Decision Support System, and appropriate mathematical models and algorithms to use for making gate allocation decisions at an international airport. As an...

The move of Hong Kong International Airport from the city centre to a suburban area in July 1998 provided sufficient capacity to meet the increasing demand of passenger and air-cargo flows in Hong Kong in the foreseeable future. However, the move has adverse side effects such as causing the...

Just-in-time (JIT) trucking service, i.e., arriving at customers within specified time windows, has become the norm for freight carriers in all stages of supply chains. In this paper, a JIT pickup/delivery problem is formulated as a stochastic dynamic traveling salesman problem with time windows...

A significant portion of the 200,000 people working in Hong Kong's central business district (CBD) relies on buses as their primary means of transport. During peak hours, nearly a thousand double-decker buses pour into a tiny area of 150 ha. This causes traffic congestion and air pollution....

We bound the difference in performance measures among different orders of tandem queues when service times are nonoverlapping. Two types of nonoverlapping service times, with respect to (w.r.t.) tasks and w.r.t. customers, are defined; it is not required that service times be independent. For...

We consider a single-commodity production-inventory supply chain in a supplier–retailer setting with batch production for the supplier, batch ordering for the retailer, and intermediate storage between the supplier and the retailer. These features have been studied in the literature of supply...
