A constraint-based approach to Enigma 1225

A Chance Constraint Approach to Multi Response Optimization Based on a Network Data Envelopment Analysis

In this paper, a novel approach for multi response optimization is presented. In the proposed approach, response variables in treatments combination occur with a certain probability. Moreover, we assume that each treatment has a network style. Because of the probabilistic nature of treatment combination, the proposed approach can compute the efficiency of each treatment under the desirable reli...

SDO relaxation approach to fractional quadratic minimization with one quadratic constraint

In this paper, we study the problem of minimizing the ratio of two quadratic functions subject to a quadratic constraint. First we introduce a parametric equivalent of the problem. Then a bisection and a generalized Newton-based method algorithms are presented to solve it. In order to solve the quadratically constrained quadratic minimization problem within both algorithms, a semidefinite optim...

Investigation of Teachers' Lived Experiences of Student's Bullying Behavior: A Phenomenological Approach

Introduction: Bullying is a complicated behavioral problem that is mostly occurs at schools. There are many quantitative studies on this issue but few qualitative studies have investigated this problem. Therefore, this study was performed to investigate teachers' lived experiences of student's bullying behavior. Method: This is a qualitative study with a phenomenological approach. In this study...

Agent-based approach for cooperative scheduling

This paper studies the multi-factory production (MFP) network scheduling problem where a number of different individual factories join together to form a MFP network, in which these factories can operate more economically than operating individually. However, in such network which known as virtual production network with self-interested factories with transportation times, each individual facto...
