The present study demonstrates that the product line choice of a firm depends on the elasticity of substitution between products (and the organizational and coordination requirements that it implies), the bargaining power of managers of different product divisions, and marketing prospects of...

An ordinary linear programming problem is formulated as <disp-formula><tex-math><![CDATA[$$\mbox{Maximize} z = cz$$]]></tex-math></disp-formula> under the constraints <disp-formula><tex-math><![CDATA[\begin{eqnarray*} Ax \leqq b,\\ x \geqq 0, \end{eqnarray*}]]></tex-math></disp-formula> where A is a matrix with m rows and n columns, x and c are column vectors with n elements, and b is a column vector with n elements. The theory of stochastic linear programming first suggested by Tintner [Tintner, G....
