摘要:

The formulation and methodology of curve fitting polynomials by discounted least squares can be simplified through the use of the discrete Laguerre polynomials, which are mutually orthogonal with respect to an exponential weighting function. One advantage of this formulation is that the firstk+ 1 coefficients of a fitting polynomial of degreem>kare the same as those of a fitting polynomial of degreek.The Laguerre polynomials are introduced and their properties are derived. The recursive method for computing coefficients is shown to have a simple structure that is independent of the degreekof the fitting polynomials. In addition, some properties of the method of smoothing and forecasting are discussed.

摘要:

This paper discusses the mean flow-time flow-shop problem. Several new properties have been developed that provide the reader with a better understanding of this model. A class of solvable cases is defined that includes the known solvable cases.

摘要:

In a material control problem by Hodgson and Lowe [4], an iterative algorithm is used to minimize a function which considers, fornitem classes, the setup cost, inventory carrying cost, and warehouse material handling cost. We show that each subproblem in this iterative scheme can be reduced to a convex program. As a by-product of this result, we show that a stationary point of a Hodgson-Lowe subproblem is a global minimum of the subproblem.
