This paper proposes several novel hybrid ant colony optimization (ACO)-based algorithms to resolve multi-objective job-shop scheduling problem with equal-size lot splitting. The main issue discussed in this paper is lot-splitting of jobs and tradeoff between lot-splitting costs and makespan. One of the disadvantages of ACO is its uncertainty on time of convergence. In order to enrich search pat...

The effective maintenance scheduling of power system generators is very important for the economical and reliable operation of a power system. his represents a tough scheduling problem which continues to present a challenge for efficient optimization solution techniques. This paper resents the application of metaheuristic approaches, such as a genetic algorithm (GA), simulated annealing (SA) an...

This paper proposes a novel approach to schedule real-time applications represented by Fork-Join (FJ) task graphs on a cluster platform. The novelty of our approach lies in its ability to efficiently utilize the power of the cluster’s computational resources to improve the system throughput. Our approach integrates two heuristic scheduling algorithms: the first algorithm (partition algorithm) w...

Scheduling product batches in pipelines is a very complex task with many constraints to be considered. Several papers have been published on the ubject during the last decade. Most of them are based on large-size MILP discrete time scheduling models whose computational efficiency greatly iminishes for rather long time horizons. Recently, an MILP continuous problem representation in both time an...

Video streaming is becoming increasingly popular among the wireless users. However, supporting video streaming over the wireless networks is not an easy task due to the dynamic radio propagation environment, limited radio resources as well as Quality of Service (QoS) requirements of the video streaming that need to be satisfied at acceptable levels. Most studies proposed to support video stream...

The main cause of the wasted energy consumption in wireless sensor networks is the packet collision. The packet scheduling algorithm is therefore introduced to solve this problem. This paper presents an analytical model for predicting the performance of packet scheduling algorithms in wireless sensor networks. This model can be used to predict the performance of the packet scheduling algorithm ...

— In the present scenario the differences amongst collecting, transporting, storing and processing information are quickly disappearing. As our ability to gather, process and distribute information grows the demand for even more sophisticated information processing system grows much faster. Distributed Computing is an optimal solution to fulfill these ever-changing demands. Distributed Computin...
