Ant Colony Optimization for the Total Weighted Tardiness Problem
نویسندگان
چکیده
In this article we present an application of the Ant Colony Optimization (ACO) metaheuristic to the single machine total weighted tardiness problem. First, we briefly discuss the constructive phase of ACO in which a colony of artificial ants generates a set of feasible solutions. Then, we introduce some simple but very effective local search. Last, we combine the constructive phase with local search obtaining a novel ACO algorithm that uses a heterogeneous colony of ants and is highly effective in finding the best-known solutions on all instances of a widely used set of benchmark problems.

Unrelated Parallel Machines Scheduling Problem Using an Ant Colony Optimization Approach
Total weighted tardiness is a measure of customer satisfaction. Minimizing it represents satisfying the general requirement of on-time delivery. In this research, we consider an ant colony optimization (ACO) algorithm to solve the problem of scheduling unrelated parallel machines to minimize total weighted tardiness. The problem is NP-hard in the strong sense. Computational results show that th...

In this extended abstract we present an algorithm based on the Ant Colony Optimization (ACO) metaheuristic for the single machine total weighted tardiness problem, a well known NP–hard scheduling problem. Our ACO algorithm is currently among the best algorithms known for this problem type. In particular, we will discuss three elements that enable it to find very good solutions quickly. These ar...

In this paper the NP-hard single machine total weighted tardiness scheduling problem in presence of sequence-dependent setup times is faced with a new Ant Colony Optimization (ACO) approach. The proposed ACO algorithm is based on a new global pheromone update mechanism, which makes the pheromone trails asymptotically range between two bounds arbitrarily fixed and the ACO learning mechanism ind...
