When estimating higher-order derivatives of a partial differential equation, it is often essential to compute approximations for artificial boundaries. In this paper we formulate an explicit discretization model for approximation of beta-coefficient of Capital Asset Pricing Model (CAPM). The...

A not-for-profit organization's reported ratio of expenditures on program services to total expenditures is a key performance metric for many donors, which may lead the manager of a not-for-profit organization to manipulate this ratio. This paper presents a theoretical model to examine when and...

Context. A method for constructing an algorithm for stabilizing the interoperability of a production line is considered. The object of the study was a model of a multi-operational production line. Objective. The goal of the work is to develop a method for constructing an optimal algorithm for...
