With the I-type plastic extrusion die for example, the advantages and disadvantages between the traditional design method and optimization design method were compared. The design was studied via finite element numeric analysis combined with optimization, whose objective was the equal average flow velocity of each sub-field of profile cross section at extrusion die. And the optimization design w...

This paper reviews a cyclic scheduling model of repetitive manufacturing environments consisting of exible machines and multi-stage jobs. We explicitly model two system performance measures, throughput and ow time, while incorporating variability arising from uncertainty in operation processing times. We present an iterative approximation scheme to estimate the two moment behavior of our perfor...

Against this background, the novel contriby efficient Multi-User Detection (MUD) techniques have recently bution of this paper is that we propose a MMSE-assisted Iteraattracted intensive research interes...

This paper proposes the modification of a technique of simultaneous optimization of multiple response variables that works using a Bayesian predictive distribution, to incorporate different weights to the response variables according to their importance in the products. To achieve this, the desirability function has been incorporated to the original proposal. This research shows by representing...

The Markov library contains methods to compute the ideals and primary decomposition associated to Bayesian networks described in [1]. This library is implemented in a computer algebra system, Singular ([2]). This document describes how to use this library for the various computations. In Section 1, we show how to compute various ideals associated to Bayesian networks without hidden variables. I...

In Section 4, we described briefly how temporal consistency could be enforced by incorporating into the objective function of Eq. 2 a penalty term involving the flow variables used to solve the QMIP problem of Eq. 3. In this Section, we justify the form of this additional term in more detail. We first define the constraints that must be imposed on the flow variables to ensure temporal consisten...

The present research work is concerned with the effects of optimum process variables in elevated temperature hydro-mechanical deep drawing of 5052 aluminum alloy. Punch-workpiece and die-workpiece friction coefficients together with the initial gap between the blank holder and matrix were considered as the process variables which, in optimization terminology, are called design parameters. Since...
