Demand amplification, or the bullwhip effect, has been identified as contributing to increased uncertainty in the supply chain and hence poor performance in terms of increased costs, protracted lead-times and poor customer service levels. This paper shows the application of a simulation based improvement activity focussing on the ordering decisions within a supply chain. An example of a prelimi...

supply chain management is one of modern approach in the field of operation and production management. nowadays success and survival of manufacturing organizations depend on effectiveness and productivity of supply chains. this research tries to investigate contributing factor to enhance supply chain productivity. then by using fuzzy promethe-a multiple attribute decision making (madm) - tous a...

The purpose of the present study was the simulation of climate change effects on groundwater resources in Iran by using the dynamic systems approach. The approach was performed through system dynamics modeling process including problem explanation, system description, model development, model testing, and the use of the model for policy analysis. The impact of the application of various exogeno...

Volume infusions are one of the commonest clinical interventions in critically ill patients yet the relationship of volume to cardiac output is not well understood. Blood volume has a stressed and unstressed component but only the stressed component determines flow. It is usually about 30 % of total volume. Stressed volume is relatively constant under steady state conditions. It creates an elas...

Recently Debates about Energy and the issue of global warming have led to the use of new energy. One of the best options for this purpose is the use of a new hybrid system of power, heating and refrigeration, with its thermal source of solar and geothermal energy. In the present study, used a combined cooling, heating and power system based on the organic Rankine cycle and the Ejector Refrigera...

While agro-industrial studies are influenced by economics theories researches on supply chain addresses questions of operational efficiency and effectiveness. This research aims to verify if there is any established system to evaluate supply chain performance in Brazil. The unit of analysis is a poultry meat supply chain that has a significant production volume driven to exportation.
