Abstract Simple functional forms for utility require restrictive structural assumptions that are often contrary to observed behavior. Even so, they are widely used in applied economic research. I address this issue using a two-part adaptive experimental design to compare the predictions of a popular parametric model of decision making under risk to those of non-parametric bounds on indifference curves. Interpreting the latter as an approximate upper bound, I find the parametric model sacrifices very little in terms of predictive success. This suggests that, despite their restrictiveness, simple functional forms may nevertheless be useful representations of preferences over risky alternatives.

The paper aims to develop a procedure for calculating parameters characterizing the process of milling box-shaped parts with waffle-grid shell design made of high-strength aluminum alloys. The calculated parameters are approximated by power equations and are provided for various ranges of the technological coefficient for the bottom of the waffle-grid structure. During final machining and penetration, when setting up the advance, one should take into account the inertial properties of the linear drives of the machines, in addition to this the advance of the tool and the angle of penetration should be constrained to prevent deformation of the bottom of the pocket. Based on the results of the math simulations, the ranges of acceptable values for advance per a tooth and the penetration angle were defined. The optimal ranges for milling parameters were established, which are recommended for implementation in the manufacturing processes of machining box-shaped parts with waffle-grid shell design made of high-strength aluminum alloys. Key words: milling, shell, pocket, aluminum alloys, optimization, waffle-grid structure.
