摘要:

This paper outlines a formal description for the distribution by value curve (DBV), which is widely employed to represent size distributions of multi-item inventories. It gives a convenient mathematical expression for the often used lognormal DBV curve and reveals its symmetrical nature when represented on a unit square. A Pareto DBV curve that has been used in the literature is detailed and shown to be skewed to one direction. Two alternative forms for the DBV curve are suggested: symmetric-Pareto and power, which may be more suited to mathematical manipulation. The latter can also represent a wider class of inventories.

摘要:

Linear programming is one of the more important types of mathematical models used in industrial engineering. David Shearn, in this note, provides an important addition to the pedagogical literature on this topic. Specifically, the note offers a numerical example incorporating a wide range of sensitivity-related questions, some of which are specifically designed for an interactive computational mode of teaching/learning.
