Cost Function Modelling for Semi-automated SC, RTG and Automated and Semi-automated RMG Container Yard Operating Systems

This study analyses the concept of cost functions for semi-automated Straddle Carrier (SC), Rubber Tyred Gantry (RTG) and automated Rail Mounted Gantry (RMG) container yard operating cranes. It develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...

Assessing Benefits of Coordination on Safety in Automated Highway Systems

In this report, we present a methodology for assessing the benefits of different vehicle coordination strategies on the safety of a platoon during emergency braking. One can say that a coordinated braking strategy B is more beneficial than a strategy A, if strategy B leads to a larger reduction in the probability of a collision, the expected number of collisions, and the expected relative veloc...

Tools for Safety - Throughput Analysis of Automated Highway Systems '

The development of two tools to study the performance of automated highways is presented. The first is a spacing tool that produces the minimum spacing necessary for two vehicles not to collide, as a function of their initial velocities and their deceleration capabilities. The second tool investigates the multiple collisions that may occur in a string of vehicles if the requirements made by the...

Simulation-Based Automated Verification of Safety-Critical Chassis-Control Systems

This paper presents and exemplifies a novel methodology to perform simulation-based automated testing for verification of complex chassis-control systems. The methods are derived from computer-game principles and regard the system under test as an opponent that is defeated when the specification is violated. The methodology is demonstrated on an auto-coding implementation of a brake-blending fu...
