“…The fuzzy comprehensive evaluation is one kind of effective multitudinous factors decision method used to evaluate the object synthetically affected by various factors [4][5][6][7][8], and the influence factors of the machining technological of middle-convex and varying ellipse piston always are uncertain [9][10][11], so the fuzzy comprehensive evaluation is the optimum method to evaluate machining technological of middle-convex and varying ellipse piston.…”

Abstract. Machining precision of the middle-convex and varying ellipse piston is an important aspect influenced by machining technological, and influencing the functional performance of engine directly. The scientific and rational machining technological is the key to determine the manufacturing quality and cost-performance ratio of the middle-convex and varying ellipse piston. Machining technological evaluation of the middle-convex and varying ellipse piston is one important and complicated process influenced by many different factors directly, the fuzzy comprehensive evaluation method is proposed to evaluate the machining technological of the middle-convex and varying ellipse piston based on fuzzy logic. Finally, an example of machining technological evaluation on one certain middle-convex and varying ellipse piston for the illustration of the proposed methodology is presented. The feasibility and rationality of the methodology are verified by the experimental result.
