One of the factors which has been used in thismethod is accomplishing the house of quality and as a result isdetermining the degree of importance of the customer's requirements.Kano model is a kind of two dimensional ...  Read More

A new exponential cluster validity index using Jaccard distance

Mohamad Hossein Fazel Zarandi; Solmaz Ghazanfar Ahari; Nader Ghaffari-Nasab

Volume 10, Issue 27 , January 2012, Pages 22-43

Abstract
  Estimating the optimal number of clusters in an unsupervisedpartitioning of data sets has been a challenging area in recent years.These indices usually use two criteria called compactness andseparation to evaluate the efficiency of the performed clustering. Inthis paper a new separation measure for ECAS ...  Read More

An Artificial Bee Colony algorithm approach for locating optimal switch location in cellular mobile communication network

S.M. Ali Khatami Firouzabadi; Amin Vafadar Nikjoo

Volume 10, Issue 27 , January 2012, Pages 44-67

Abstract
  In this research, we use Artificial Bee Colony (ABC) algorithm tosolve cell to switch assignment problem (CTSAP) that is NP-hard. InCTSAP, there are cells and switches in which cells locations arepredetermined. The objective of problem is optimal assigning of cellsto switches with minimum cost. Here, ...  Read More

Developing two multi-objective algorithms for solving multi-objective flexible job shop scheduling problem considering total consumed power per month

Seyed Habib A Rahmati; Mostafa Zandieh

Volume 10, Issue 27 , January 2012, Pages 118-143

Abstract
  In this paper, to make flexible job shop scheduling problem (FJSP)more realistic, an operational factor is considered in its model. Thisfactor, which is called optimizing total consumed electric power permonth, is known as the most important factor in calculation of theelectric cost of the industries. ...  Read More

Statistical Control of Time and Cost Performance Indices in Construction Projects: A Case Study

Ali Akbar Akbar; Amir Salehipour

Volume 10, Issue 27 , January 2012, Pages 144-166
