Determining parameters in multi-pass turning operations under fuzzy environmental

Despite convex mathematical optimization methods be applied to general linear optimization problems it can also be applied in a special class of nonlinear optimization. As ambiguity and vagueness are natural and ever-present in real-life situations requiring solutions, it makes perfect sense to attempt to address them using fuzzy convex optimization. In this work, two fuzzy convex approaches based on two fuzzy linear ones are presented. To illustrate the eciency of these proposals, a manufacturing process problem is solved.
