This study aims to discuss the solution methodology for a closed-loop supply chain (CLSC) network that includes the collection of used products as well as distribution of the new products. This supply chain is presented on behalf of the problems that can be solved by the proposed meta-heuristic...

Due to the enormous demand for crude oil, the selection of appropriate and economical techniques to enhance the oil recovery are always considered as the major concerns in reservoir developments. Polymer flooding is considered as one of the chemical enhanced oil recovery techniques especially...

Purpose The purpose of this paper is to present a methodology to assist enterprise decision makers (DMs) to select from a number of processes during Business Process Reengineering (BPR) according to organizational objectives. Indeed, after the identification and classification of process and...

Purpose – The purpose of this paper is to investigate the impact of dividing the companies’ customers into different priority groups to be served according to their payment history and feedback on the business performance areas: service quality (SQ), business process time (BPT), business...

There are two versions in the literature of counting co-author pairs. Whereas the first version leads to a two-dimensional (2-D) power function distribution; the other version shows three-dimensional (3-D) graphs, totally rotatable around and their shapes are visible in space from all possible...

The theoretical approach of the mathematical model of Social Gestalts and the corresponding methods for the 3-D visualization and animation of collaboration networks are presented in Part I. The application of these new methods to male and female networks is shown in Part II. After regression...

In mammals, the circadian clock is driven by multiple integrated transcriptional feedback loops involving three kinds of central clock-controlled elements (CCEs): E-boxes, D-boxes and ROR-elements. With the aid of CCEs, the concentrations of the active proteins are approximated by the delayed...

The forecast can be defined like approximately of the unknown events from the future; this thing is necessary because of the existence of some unknown events, but this events play an important role in taking some decisions. It is obvious that the uncertainty's elimination is not possible, so the...

The effect of different structural designs on the performance of electrical double layer capacitors (EDLCs) has been studied through a mathematical model that considers the mass transfer and conservation of charge equations. The structural design parameters considered in this study are the...

A two dimensional, across the channel, isothermal, two-phase flow model for proton exchange membrane fuel cells (PEMFCs) is developed to investigate the interaction of dry Nafion® ionomer volume fraction (LMdry) and cathode relative humidity (RHc) in PEMFCs. The agglomerate model is used to...
