The process planning and scheduling (PPS) is to determine a solution (schedule), which tells a production facility what to make, when, and on which equipment, to process a set of parts with operations effectively. Multiobjective PPS problems become more complex because the decision maker need to make a trade-off between two or more objectives while determining a set of optimal nondominated solutions...
In this paper, the combination forecast method is presented by using minimizing the Theil-coefficient of the ARCH and GARCH and ARIMA method. The prices of cash and futures are forecasted combination forecast method. The optimal minimum variance hedging ratio is obtained by using the combination forecast results. The contribution is that combination forecast method combines the advantages of the single...
In regard to the multiple attribute decision making problems with the information about attribute weights incompletely known under the intuitionistic fuzzy environment, the score function and accuracy function are introduced. The decision making matrix with the attribute value expressed by form of intuitionistic fuzzy number is transformed into the score matrix of the alternatives. Then according...
Cellular manufacturing (CM) is an important application of group technology (GT) in which families of parts is produced in manufacturing cells or in a group of various machines. In this paper, a genetic algorithm approach is proposed for solving multi-objective cell formation problem. The objectives are the minimization of both total moves (intercell as well as intracell moves) and the cell load Variation...
