Near Optimal Disassembly Sequence Generation for Large Equipment in Nuclear Plant

An Online Genetic Algorithm for Automated Disassembly Sequence Generation

In this study, we propose an intelligent automated disassembly cell for online (real time) selective disassembly. The cell is composed of an industrial robotic manipulator, a camera, range-sensing and component segmentation visual algorithms. The cell prototype allows for robotic sensory-driven disassembly under uncertainty. An online genetic algorithm model for selective disassembly is also pr...

Qualification of Microprocessor-Based Equipment for Nuclear Power Plant Environments

In the past several years, studies have been performed by Oak Ridge National Laboratory, Sandia National Laboratory, and Brookhaven National Laboratory in a confirmatory research program initiated by the U.S. NRC with the objective of identifying methodologies for enhancing current qualification guidelines for the application of microprocessor-based I&C in safety-related systems in nuclear powe...

Fast Generation of Near-Optimal Plans for Eco-Efficient Stowage of Large Container Vessels

Eco-Efficient stowage plans that are both competitive and sustainable have become a priority for the shipping industry. Stowage planning is NP-hard and is a challenging optimization problem in practice. We propose a new 2-phase approach that generates near-optimal stowage plans and fulfills industrial time and quality requirements. Our approach combines an integer programming model for assignin...

Design Evaluation Method for the Disassembly of Electronic Equipment

Due to their short lifecycle, personal computers are being sent to the landfill at an accelerated pace. Their disposal has a hazardous impact on the environment thus necessitating the implementation of widespread recycling efforts. Currently, in the US, computer recycling businesses exist on a profit making model and not simply for the betterment of the environment. Therefore, efforts must be m...
