Requirements of digitization, intellectualization, and integration for the programming management air transportation have been recommended as information technology booms. A variety single ground movement optimization problems discussed with few taking impact other segments into account. In this research, bilevel is applied to simultaneously consider three including gate assignment, taxi path s...

Extended aircraft arrival management under uncertainty has been previously studied in the literature using two-stage stochastic optimization case of a single initial approach fix (IAF) and runway. In this paper, we propose an extension taking into account: (i) multiple IAFs feeding landing runway, (ii) having different flight status (at-departure-gate or airborne) when making first-stage decisi...

Petrify is a tool for (1) manipulating concurrent speciications and (2) synthesis and optimization of asynchronous control circuits. Given a Petri Net (PN), a Signal Transition Graph (STG), or a Transition System (TS) 1 it (1) generates another PN or STG which is simpler than the original description and (2) produces an optimized net-list of an asynchronous controller in the target gate library...

The problem of flight delay prediction is approached most often by predicting a class or value. However, the aviation industry can benefit greatly from probabilistic predictions on an individual basis, as these give insight into uncertainty predictions. Therefore, in this study, two forecasting algorithms, Mixture Density Networks and Random Forest regression, are applied to predict delays at E...

Bayesian modeling method and slice analysis techniques show good effect in cycle-accurate power analysis of combinational circuit. In this paper, we use virtual signal logical depth assignment to resolve the problem that signal loop can not be sliced in sequential circuits. With this method, we build cycle-accurate power model based on Bayesian inference and slice analysis techniques. The exper...

We consider the over-constrained Airport Gate Assignment Problem where the number of flights exceed the number of gates available, and where the objectives are to minimize the number of ungated flights and the total walking distances. The problem is formulated as a binary quadratic programming problem. We design a greedy algorithm and use a Tabu Search meta-heuristic to solve the problem. The g...

Layout Optimization in Ultra Deep Submicron VLSI Design. (May 2006) Di Wu, B.E., Beijing University of Posts and Telecommunications; M.S., East Carolina University Co–Chairs of Advisory Committee: Dr. Rabi N. Mahapatra Dr. Jiang Hu As fabrication technology keeps advancing, many deep submicron (DSM) effects have become increasingly evident and can no longer be ignored in Very Large Scale Integr...
