A System Dynamics Approach to Designing Technological Innovation Management Model in Downstream Petrochemical Industries

Special attention to the relative advantages of the economy is the best way toward economic development in every country. Owing to its considerable natural oil and gas resources, Iran has a high potential for the development of these industries. In the value chain process of these God-given resources, a wide diversity of final downstream petrochemical products has a significant charm and scope ...

Static and Dynamic Analysis of Railway Track Sleeper

The increased speed and weight of modern trains puts the components of a railway track in a highly dynamic load situation. Irregularities of the wheels and rails induce substantial dynamic loads that have to be accounted for in the procedure of designing the railway track. The concrete sleeper is an essential part of the track structure and there is a growing demand for improved analytical tool...

Technological Innovation

This paper considers how manufacturing companies within the supply chain are increasingly expected to provide technologically innovative solutions, rather than simple components. Large global companies are becoming system builders, but as they devolve greater responsibility for technology to suppliers, they are also squeezing cost and timescales. Planning for specific future technology requirem...
