Improving ship yard ballast pumps’ operations: A PCA approach to predictive maintenance

Improving rail network velocity: A machine learning approach to predictive maintenance

Rail network velocity is defined as system-wide average speed of line-haul movement between terminals. To accommodate increased service demand and load on rail networks, increase in network velocity, without compromising safety, is required. Among many determinants of overall network velocity, a key driver is service interruption, including lowered operating speed due to track/train condition a...

Improving Energy Efficiency of Ships through Optimisation of Ship Operations

Increased environmental concerns, resulted in new legislation, and high and volatile fuel prices are today’s driving forces to reduce operational costs and become greener. Reduction of fuel consumption acts as the main contributor towards this. In the context of the given economic pressure and from international law point of view, the amount of energy-savings by vessel fuel should be increased ...

A Model Predictive Control Approach to Generator Maintenance Scheduling

Multi-agent Simulation of Sawmill Yard Operations

This paper reports the findings of using multi-agent based simulation model to evaluate the sawmill yard operations within a large privately owned sawmill in Sweden, Bergkvist Insjön AB in the current case. Conventional working routines within sawmill yard threaten the overall efficiency and thereby limit the profit margin of sawmill. Deploying dynamic work routines within the sawmill yard is n...

Performance assessment and improvement of yard crane rehandling strategies for improving port drayage operations

Seaport terminals recognise the need to change current practices in order to improve regional air quality while enhancing their terminals’ competitiveness. One area that terminals can do better at is to improve their yard crane operations and in turn reduce the trucks in-terminal delay. This study examines various container rehandling strategies by the yard cranes with the goal of improving the...
