This paper is concerned with a vehicle routing problem with soft time windows (VRPSTW) in a fuzzy random environment. Two objectives are considered: (1) minimize the total travel cost and (2) maximize the average satisfaction level of all customers. After setting up the model for the VRPSTW in a...

This paper discusses the quay crane scheduling problem at indented berth, an extension to the current quay crane scheduling problem in the field of container terminal operation. A mixed integer programming model by considering the unique features of the quay crane scheduling problem at indented...

This paper revisits the hypothesis of a quality segmented charter market using dry bulk-Panamax time-charter rates from the shipping boom period of 2003-2007. Through generalized additive models (GAMs) the authors assess whether increasing awareness and regulation over time has brought about a...

This paper develops a mathematical model to quantify the market share of a given port. A Monte Carlo simulation based algorithm is proposed to estimate the port market share. A study is subsequently conducted to explore the characteristics of the landbridge system in China and Southeast Asia,...

This paper investigates a number of operational and environmental performance measures, in particular those related to transportation operations, within a closed-loop supply chain. A mathematical model in the form of a linear programming formulation is used to model the problem, which captures...

This paper proposes a more realistic multi-period liner ship fleet planning problem for a liner container shipping company than has been studied in previous literature. The proposed problem is formulated as a scenario-based dynamic programming model consisting of a number of integer linear...

We develop a heuristic for the period vehicle routing problem that uses an integer program and the record-to-record travel algorithm. Our heuristic produces very high-quality results on standard benchmark instances. We extend our heuristic to handle real-world routing considerations that involve...
