Abstract: The textile industry is a generator of high volumes of waste water with a high content of pollutants such as azo dyes, which are recalcitrant and persistent in the environment, these ones have been of interest in the last decades for the entities in charge of

Abstract: In many countries, buildings are usually made of unreinforced clay masonry walls, especially in Colombia. These constructions have low resistance and ductility, and are very vulnerable to seismic events, due to their low capacity of energy dissipation. This p

Minimising Total Flowtime in a No-Wait Flow Shop (NWFS) using Genetic Algorithms
Imran Ali Chaudhry, Isam A-Q. Elbadawi, Muhammad Usman, Muhammad Tajammal Chugtai.
Abstract: This paper considers a no-wait flow shop scheduling (NWFS) problem, where the objective is to minimise the total flowtime. We propose a genetic algorithm (GA) that is implemented in a spreadsheet environment. The GA functions as an add-in in the spreadsheet.
