The generalized sensibility analysis of the profit in a company which produces n-assortments

This article presents the most important elements of the sensibility analysis of the profit in a company which produces n-assortments, when a volume of sale of each assortment and its unit price, unit variable cost and fixed costs of a company can singly grow with constant rates. The article contains analytical formulas for the generalized operating leverage and demand, price and cost break-even point. The generalized operating leverage was formulated as a linear function of growth rates of the sales volume of assortments. It describe the relation among demand growth rates of assortments which makes it possible to obtain a given return rate (a given level) of the company profit. The authors distinguish between demand, price and cost break-even points. The demand break-even points shows the relation among demand growth rates of n-assortments, the price displays the relation among unit price growth rates and the cost break-even point shows the relation among unit variable cost growth rates when the profit of a company declines one hundred per cent.
