Solving the Airline Recovery Problem By Using Ant Colony Optimization

  In this paper an Ant Colony (ACO) algorithm is developed to solve aircraft recovery while considering disrupted passengers as part of objective function cost. By defining the recovery scope, the solution always guarantees a return to the original aircraft schedule as soon as possible which means least changes to the initial schedule and ensures that all downline affects of the disruption are ...

TOPOLOGY OPTIMIZATION OF SPACE STRUCTURES USING ANT COLONY METHOD

In this article, the ant colony method is utilized for topology optimization of space structures. Strain energy of the structure is minimized while the material volume is limited to a certain amount. In other words, the stiffest possible structure is sought when certain given materials are used. In addition, a noise cleaning technique is addressed to prevent undesirable members in optimum topol...

Time Using Ant Colony Optimization

We describe an Ant Colony Optimization (ACO) algorithm for solving a single machine scheduling problem. In the operating situation modeled, setup times are sequence dependent and the objective is to minimize total tardiness. This problem has previously been treated by Rubin & Ragatz [1995] and by Tan et al. [2000] among others. A new feature using look-ahead information in the transition rule o...

OPTIMIZATION OF TREE-STRUCTURED GAS DISTRIBUTION NETWORK USING ANT COLONY OPTIMIZATION: A CASE STUDY

An Ant Colony Optimization (ACO) algorithm is proposed for optimal tree-structured natural gas distribution network. Design of pipelines, facilities, and equipment systems are necessary tasks to configure an optimal natural gas network. A mixed integer programming model is formulated to minimize the total cost in the network. The aim is to optimize pipe diameter sizes so that the location-alloc...
