The aim of the paper is to address the issue of operational improvements in manufacturing firms, especially when yield losses result in a significant increase of the production cost. In a multistage production environment the firm must decide which production stage(s) should receive more “attention” in order to minimize the overall cost incurred from yield losses. Yield variability is a factor ...

In this chapter we discuss a tactical optimisation problem that arises in a multistage distribution system where customer orders can be delivered from any stockpoint. A simple rule to allocate orders to locations is a break quantity rule, which routes large orders to higher-stage stockpoints and small orders to end-stockpoints. A so-called break quantity determines whether an order is small or ...

Because applying machine learning techniques in support of clinical decision would improve decision makers in healthcare, we present in this paper a comparative framework of Support Vector Machine (SVM) classifiers based on post operative patient (POP) data. We compare the performance of a single multiclass SVM and a multistage SVM (MSVM) to those obtained by a number of other classifiers prese...

| In this paper we present the multistage oo-line method, a new and rather natural way to model oo-line packet routing problems, which reduces the problem of oo-line packet routing to that of nding edge disjoint paths on a multistage graph. The multistage oo-line method can model any kind of routing pattern on any graph and can incorporate the size of the maximum queue allowed in any processor....

Prediction of pressure pulsation magnitude and their harmonic components for a multistage reciprocating compressor, piping and reservoir system depends on the input design and operating parameters. In the present paper, the results of the theoretical study carried out to study the effect of such parameters on pressure pulsations and their harmonics have been presented. The effect of pipe diamet...

Currently, the threshold T must be entered manually, based on given or estimated values for the SNR of the degraded image. Future work will look at ways to automate this process. Also, we found that at very low SNR, the AMP median filter introduces a few speckles into the restored image. We suspect that this may be due to incorrect adaption in regions of exceptionally high noise levels. Further...

An exact transformed culling method for any number of traits or stages of selection with explicit solution for multistage selection is described in this paper. This procedure does not need numerical integration and is suitable for obtaining either desired genetic gains for a variable proportion selected or optimum aggregate breeding value for a fixed total proportion selected. The procedure has...

In this paper we present the multistage off-line method, a new and rather natural way to model off-line packet routing problems, which reduces the problem of off-line packet routing to that of finding edge disjoint paths on a multistage graph. The multistage off-line method can model any kind of routing pattern on any graph and can incorporate the size of the maximum queue allowed in any proces...

The authors present an analytical method to assess the average criterion performance of the selected candidates as well as the adverse impact and the cost of general multistage selection decisions. The method extends previous work on the analytical estimation of multistage selection outcomes to the case in which the applicant pool is a mixture of applicant populations that differ in their avera...
