Solid waste management is one of the major environmental concern in the United States. Over 5 billion tons of non-hazardous solid waste materials are generated in US each year. Out of which more than 273 million scrap tires (approximately 3.6 million tons) are generated each year. In addition to this, about 3 billion tires are stockpiled. Several studies have been carried out to reuse scrap tir...

The exclusion of inherent process variations in the current deterministic design methods for sheet metal forming can lead to very unreliable result that may cause high scrap rate, frequent rework, machine shut down and thus huge loss of profit. In this paper, a general approach is presented to quantify the uncertainties and to incorporate them into RSM model so as to conduct probabilistic based...

lexible production: this key strategic goal of every modern manufacturing company has made robotic tending of press brake machines a common sight in sheet metal fabrication workshops. And with advantages over manual tending like better quality, higher efficiency, improved safety, less scrap and accurate repeatability, its popularity is certain to grow. One limitation is slowing its advance, how...

In this thesis, we address the tactical planning decision problem of ingot sizing in an aluminum sheet manufacturing facility. Ingots used for sheet manufacturing are made-to-stock, and used when necessary, to satisfy customer demands. The facility produces large ingots to exploit economies of scale in ingot casting, but customers order products frequently, and in small quantities. In this situ...
