quality inspection is an indispensable part of modern industrial manufacturing. steel as a major industry requires constant surveillance and supervision through its various stages of production. continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. once the slab is released from the casting unit, th...

Since the 1960s, downsizing has become a mode of adjustment widely used by corporate managements in the face of changing markets and economic competition (Raveyre 2005, Fayolle 2005, Lefresne and Sauviat 2008). It is an organization conscious use of permanent personnel reductions in an attempt to improve its efficiency and/or effectiveness (Cascio, 1993, Appelbaum, Close, Klasa, 1999, Freeman, ...

Efficient cutting design is essential to reduce the costs of production in the open die forging industry. This article discusses a slab cutting design problem that occurs when parallel piped items are cut from raw material steel slabs with varying widths and lengths to meet a volume requirement. The problem is modeled as a two-dimensional cutting stock problem or bin packing problem with size-c...

The aerospace industry is one of the biggest consumers of advanced materials because of its unique combination of mechanical and physical properties and chemical stability. Highly alloyed stainless steel, titanium alloys and nickel based superalloys are mostly used for aerospace applications. High alloyed stainless steel is used for the shafts of aero engine turbines, titanium alloys for compre...
