considered supply chain in this article consists of one vendor and multiple retailers where the vendor applies vendor managed inventory. considering vendor as a leader and retailers as followers, stackelberg game theory is applied for modeling and analyzing this system. a general mixed integer nonlinear model is developed which can optimizes the performance of the system under revenue sharing c...

for designing tillage implements it would be better to estimate soil forces exerted to the implements. many researches showed that numerical method of discrete element method (dem) is the cheapest and fastest technique for modeling granular material such as soil and especially sandy soil. in this study, paraplow and bentleg tines performance was compared with conventional tine using experimenta...

this study aims to investigate the effect of information technology on quality performance. the research model has been proposed based on relationships among research variables and previous studies on information technology. population was all of department’s managers and personnel of marketing and sale, manufacturing and quality control in iran khodro and saipa companies. to collect data, a fi...

The practice of ‘writing to learn’ has been propounded as fast-tracking the dynamic process of noticing problems in L2 writing. However, a marked melioration in learners’ attempted output requires a form of corrective feedback, among which modeling has proven to bear vigorous input enhancement effects. The present study attempted to inspect what EFL learners notice throughout their own output a...

As hardware becomes faster and bandwidth greater, the determination of the performance of software based systems during design, known as Software Performance Engineering (SPE), is a growing concern. A recent seminar of experts at Dagstuhl and the First International Workshop on Software and Performance have both highlighted the need to bring performance evaluation into the software design proce...

During the last decade the gap between software modeling and performance modeling has been closing. For example, UML annotations have been developed to enable the transformation of UML software models to performance models, thereby making performance modeling more accessible. However, as of yet few of these tools are ready for industrial application. In this thesis we explorer the current state...
