Oil terminals are widely used to store various liquids and gases. The refinery scheduling problem is one of the most challenging problems in operational research due to the complexity of the refinery scheduling operations and the corresponding process models. In this paper, we present a model by which a decision maker should be able to choose the optimal number of tanks, tank size and truck arr...
تحلیل پوششی داده ها روشی برای ارزیابی کارایی مدیریت واحد های تصمیم گیری است. اخیراً dea برای بررسی کارایی فرآیند دو مرحله ای توسعه یافته است که همه خروجی ها از مرحله اول، اندازه های میانی هستند که ورودی برای مرحله دوم را می سازند. چارچوب ارزیابی کارایی برای سیستم های مرکب شده از دو زیر مرحله تشکیل شده که بطور همزمان کارایی سیستم تجمیع شده وهر زیر مرحله را محاسبه می کنند و آنرا توسعه می دهیم مرز ...
managing the supply chain plays an important role in creating competitive advantages for companies. adequate information flow in supply chain is one of the most important issues in scm. therefore, using certain information systems can have a significant role in managing and integrating data and information within the supply chain. pharmaceutical supply chain is more complex than many other supp...
In this paper, we propose a stochastic production planning model for a biofuel supply chain under demand and price uncertainties. The supply chain consists of biomass suppliers, biofuel refinery plants and distribution centers. A stochastic linear programming model is proposed within a single-period planning framework to maximize the expected profit. Decisions such as the amount of raw material...
Contemporary problems in process systems engineering often require model-based decision support tool. Among the various modelling paradigms, equation-based models and agent-based models are widely used to develop dynamic models of systems. Which is the most appropriate modelling paradigm for a supply chain? In this paper, we seek to address this important question through a well-structured benc...
In this paper, we provide new evidence regarding the pass-through of diesel and gasoline taxes to prices, and how the estimated pass-through depends on a variety of supply conditions including a measure of state residual supply elasticity, refinery and inventory constraints. In addition, we estimate the response of tax incidence to two regulatory changes in fuel markets diesel dye regulations, ...
In this paper, we provide new evidence regarding the pass-through of diesel and gasoline taxes to prices, and how the estimated pass-through depends on a variety of supply conditions including a measure of state residual supply elasticity, and refinery and inventory constraints. In addition, we estimate the response of tax incidence to gasoline content regulations, which complicate the supply c...
explaining impact of supply chain drivers on supply chain performance in iran's carpet industry
impact of supply chain drivers on supply chain performance has no far been studied. in this research we want identifying supply chain drivers, classifying them and examining their relationship with iran's supply chain performance. this research has innovation in identifying and classifying drivers and examining relationship between drivers and supply chain performance we used bsc for assessing ...
the aim of this study was to represent effective componentsin demand chain which help organizations attain high performance levelsthrough identification of these components and determining theirdegree of importance. the following questions were major ideas of thisstudy: what are the most effective components in demand chain? andhow are they effective on organizational performance? to this end,m...
Strategic decisions in a supply chain are the most important decisions for petroleum production systems. These decisions, due to high costs of transportation and storing, are costly and affected by the tactical and operational decisions in uncertain situations. In this article, we focus on designing a downstream segment for a supply chain of petroleum production systems. For this purpose, we wi...
