inventory control is one of the most important issues in supply chain management. in this paper, a three-echelon production, distribution, inventory system composed of one producer, a set of wholesalers and retailers is considered. costumers' demands can be approximated by a normal distribution and the inventory policy is a kind of continuous review (r, q). in this paper, a model based on ...
The Power Requirement in urban and metro areas is very high with an exponential growth. The distribution system with LVDS results in multiple loads fed from a bulk power transformer resulting in higher regulation in the tail ends. Moreover there is an increase in the system losses, power factor, voltage profile and performance are affected in the existing distribution system. Losses in an elect...
this paper presents a probabilistic confidence-interval based method for optimal placement of shunt capacitors in distribution networks by considering probabilistic characteristics of loads. the main objective function are reducing loss and improving the voltage profile. backward forward sweep method has been employed to obtain the power flow results in distribution system. in addition, integer...

The development of communications and telecommunications infrastructure, followed by the extension of a new generation of smart distribution grids, has brought real-time control of distribution systems to electrical industry professionals’ attention. Also, the increasing use of distributed generation (DG) resources and the need for participation in the system voltage control, which is possible ...
هر سیستم انتقال و توزیع آب شهری باید به گونه ای طراحی و اجراء شود که بتواند نیاز آبی جامعه را با فشار کافی و در طول دوران طرح تامین کند، معمولا اتلاف آب مبتلا به تمام سیستم های توزیع است و در شرایط عادی بخش عمده ای از مصرف سرانه را تشکیل می دهد. این تحقیق که با هدف انجام مطالعه آب به حساب نیامده و تعیین اجزاء مختلف تلفات فیزیکی و غیر فیزیکی و بازده حجمی سیستم توزیع آب شهر ایوان صورت گرفته است،...
evaluation of any irrigation system consists of analyzing the measurable performance of the system in real conditions as well as during the normal operation of the farm. irrigation evaluation is a management tool that allows the system manager to make the best use of what is available. unfortunately, in most regions of iran, after the implementation of irrigation systems their performance is no...
Introduction: Corrosion and scaling of water in distribution systems in spite of imposing economic and aesthetic problems can lead to adverse effects on consumers' health. The present study was conducted to evaluate the corrosion and scaling of water distribution system of Sarableh city (Ilam, Iran) during summer and winter seasons in 2014. Materials and methods: Totally, 60 samples of wate...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
