The present paper presents the algorithmic solution, based on an Ant System metaheuristic, of an industrial production–inventory problem in a steel continuous-casting plant. The model proposed is based on an objective function, the aim of which is to find the most profitable production schedule of the steel billets. Furthermore, the model takes into account the relevant parameters of the finite...

Abstract—The reheating furnace is used to reheat the steel slabs before the hot-rolling process. The supported system includes the stationary/moving beams, and the skid buttons which block some thermal radiation transmitted to the bottom of the slabs. Therefore, it is important to analyze the steel slab temperature distribution during the heating period. A three-dimensional mathematical transie...

BACKGROUND Lack of data on occupational stress among Iranian industrial employees persuaded us to design and conduct this study to evaluate the prevalence and associated parameters of occupational stress among male employees of the Esfahan Steel Company (ESCO), one of the biggest industrial units in Iran. METHODS In this cross-sectional study, 400 male employees were sampled from the operatio...
