this study aims to deal with a more realistic combined problem of project scheduling and material ordering. the goal is to minimize the total material holding and ordering costs by determining the starting time of activities along with material ordering schedules subject to some constraints. the problem is first mathematically modelled. then a hybrid simulated annealing and genetic algorithm is...

Cloud Computing is an emerging technology for processing and storing very large amounts of data. Sometimes, anomalies and defects affect a part of the Cloud infrastructure, resulting in a degradation in Cloud performance. This work uses the Taguchi method for the design of experiments to present a methodology for identifying the relationships between the various configuration parameters that af...

In any machining operations, quality and productivity are the two important conflicting objectives. In order to give assurance for high productivity, some extent of quality has to be compromised. Similarly productivity will be decreased while the efforts are channelized to enhance quality. Therefore it is essential to optimize both quality and productivity simultaneously. Surface roughness and ...

Surface finish is one of the prime requirements of customers for machined parts. The present paper presents an experimental study to investigate the effects of cutting parameters like spindle speed, feed and depth of cut on surface finish and material removal rate on EN-8. Taguchi methodology has been applied to optimize cutting parameters. The results showed that the spindle speed (the most si...

This work describes the optimization of cryogenic treatment (CT) parameters such as the cooling rate, the soaking temperature, the soaking time, the tempering temperature and the tempering time to maximise the tool wear of high speed steel tools in dry turning of AISI 316 grade austenitic stainless steels by Taguchi method. For this purpose, four iteration of Taguchi design (L16) have been used...
