Optimization of a machining economics model with fuzzy exponents and coefficients

摘要: The primary objective of a machining economics model is to determine the optimal cutting parameters that minimize production costs while satisfying some design constraints. This paper develops solution method can derive fuzzy unit cost economic when exponents decision variables in function, and constraint coefficients are numbers. A pair two-level problems formulated calculate upper lower bounds at possibility level α. Based on duality theorem by using variable substitution technique, problem transformed into one-level conventional geometric program. Solving corresponding programs produces interval cost. examples show contain more information n...
