An Improved Discrete Particle Swarm Optimization for Tugboat Scheduling Problem in Container Terminal

2010 3rd International Conference on Information Management, Innovation Management and Industrial Engineering, 2010
Effective scheduling has a significant effect on efficiency in container terminals. This paper proposes a model of tugboat scheduling and applies an improved Discrete Chaos Particle Swarm Optimization (DCPSO) algorithm to solve this problem. DCPSO orders the position vector of particles to get a discrete scheduling solution.

Dynamic tugboat deployment and scheduling with stochastic and time-varying service demands

Transportation Research Part B: Methodological
Container ports serve as crucial logistics hubs in global supply chains, but navigating ships within such ports is complex due to restricted waterways. Tugboats play a critical role in ensuring safety and efficiency by escorting and towing ships under these conditions. However, the tugboat deployment and scheduling problem has received little attention.

Notice of Retraction: An improved particle swarm optimization algorithm for solving dynamic tugboat scheduling problem

2009 2nd International Conference on Power Electronics and Intelligent Transportation System (PEITS), 2009
The dynamic tugboat scheduling problem is a special kind of Job Scheduling Problem. Here we propose an improved particle swarm optimization (PSO) algorithm in which an entropy function and an elite set is used for better performance. When the entropy of the swarm keeps under some value in a certain period, some of the particles will be replaced ...
