Are Operating Margin, Markup and Unit Margin Good for Profit? An Approach Based on Microeconomic Theory

Managerial and Decision Economics, EarlyView.
ABSTRACT Managers often say that they want to make their company more profitable by increasing the unit margin, operating margin, or margin rate, making these strategic objectives. There is some confusion in their language, as these three metrics seem to be equivalent to maximum profit.

Intelligent optimized design of novel high‐temperature titanium alloys

Materials Genome Engineering Advances, EarlyView.
This paper presents a novel strategy that integrates machine learning with multiobjective optimization to design high‐temperature titanium alloys that simultaneously meet multiple objectives and exhibit superior comprehensive mechanical properties. This approach provides valuable references for the subsequent composition design of high‐temperature ...

Extending the hyper‐logistic model to the random setting: New theoretical results with real‐world applications

Mathematical Methods in the Applied Sciences, EarlyView.
We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

Mathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...
