karun river is the largest and most watery river in iran. this river is the longest river which located just inside iran and ahvaz metropolis drinking water supplied from karun river as well (fa.alalam.ir). karun river as the main source of water treatment plants in ahvaz, like most surface waters affected by various contaminants which caused changes in water quality of the river (www.aww.co.ir...

This work deals with effects of asymmetric stiffness on the dynamic behaviour of the rotor system. The analysis is presented through an extended Lagrangian Hamiltonian mechanics on the asymmetric rotor system, where symmetries are broken in terms of the rotor stiffness. The complete dynamics of asymmetries of rotor system is investigated with a case study. In this work, a mathematical model is ...

recent studies have indicated that the rate of successful enterprise resource planning (erp) implementation projects is reduced and risk of implementation is increased to the same extent. accordingly, this study provides a model in support of erp implementation using system dynamics approach by behavioral simulation in the vensim software environment. this study is an applied research and due t...

the paper discusses the location-allocation model for logistic networks and distribution centers through considering uncertain parameters. in real-world cases, demands and transshipment costs change over the period of the time. this may lead to large cost deviation in total cost. scenario based robust optimization approaches are proposed where occurrence probability of each scenario is not know...

Abstract In the dynamic and competitive market, managers seek to find effective strategies for new products development. Since There has not been a thorough research in this field, this study is based on a review on the risks exist in the NPD process and an analysis of risks through FMEA approach to prioritize the existent risks and a modeling behavior of the NPD process and main risks using s...

This paper explores the dynamics of trust, collaboration, and knowledge sharing in the context of a multigovernmental, interorganizational project to design and implement a new information system. Drawing on research and a case study of a successful project, the authors construct a system dynamics model and simulate a base case scenario. They then explore several scenarios in which trust, knowl...

To manage the increasing dynamics inside and outside a production system, a decentralised and autonomous control of shop floor logistics is a promising approach. The paper introduces the idea of autonomous logistic processes and presents a simulation model of a shop floor with both a conventionally planned and an autonomously controlled scenario. The decentralised and autonomous control strateg...

We propose and analyze an information-sharing application for wireless intervehicular networks, called Infoshare. Infoshare leverages the broadcast nature of the wireless medium to achieve maximum spreading of information queries among vehicles, while a smart caching policy limits the overhead resulting from useless queries and duplicated replies. We first evaluate the performance of Infoshare ...
