The problem of sequencing and scheduling airplanes landing and taking off on a runway is under consideration. We propose a new family of valid inequalities which are obtained from the study of the single machine scheduling problem polytope.

In recent years the Federal Aviation Administration (FAA) has made reduction of runway incursions a priority for surface operations throughout the national airspace system. In a series of experiments conducted in April 2001, NASA studied alternatives designed to improve the efficient movement of surface traffic and reduce runway incursions at Los Angeles International Airport (LAX). The experim...

The genetic development of the commercial broiler has led to body misconfiguration and consequent walking disabilities, mainly at slaughter age. present study aimed identify locomotion ability using image analysis automatically. A total 40 broilers that were d old (male female) placed walk on a specially built runway, their was recorded. An segmentation algorithm developed, coordinates bird’s c...
