Perspectives On Quality Coordination And Assurance In Global Supply Chains, Ling Li, John N. Warfield Jan 2011

Perspectives On Quality Coordination And Assurance In Global Supply Chains, Ling Li, John N. Warfield

Information Technology & Decision Sciences Faculty Publications

The 2007 recall of Berko Electric Toe-Space Heaters made in the US, the recall of backpack blowers made in Japan, the recalls of toys and pet food produced in China have exposed the potential of global supply chain disruptions. This product recall storm leads to the issue of quality assurance in global supply chain management. Product recalls indicate that manufacturing companies are particularly vulnerable to ensure quality when they source via a global supply chain with poor visibility. Obviously, a supply chain cannot afford this kind of sourcing and supply structure that threatens the supply-chain integrity. This special issue on …

Determinants Of The Probability Of Ship Injuries, Wayne K. Talley Jan 2009

Determinants Of The Probability Of Ship Injuries, Wayne K. Talley

Economics Faculty Publications

This study investigates determinants of the probability that an individual onboard a ship of a given shipping line will be injured (given that the ship is not involved in an accident). A Probit regression statistical model is used to investigate such determinants when ships are in port and on given types of containerships. Probit estimation results suggest that an individual is less likely to be injured in port onboard a ship that is larger in size and underway, but more likely to be injured if involved in a fall. An individual is less likely to be injured onboard a containership …

Measuring Agility Of Organizations - A Comprehensive Agility Measurement Tool (Camt), Ameya S. Erande, Alok K. Verma Jan 2008

Measuring Agility Of Organizations - A Comprehensive Agility Measurement Tool (Camt), Ameya S. Erande, Alok K. Verma

Engineering Technology Faculty Publications

Since "Agility" is ability to respond to unpredictable changes with quick response and profitability, it is not industry specific. This "not industry specific" nature of agility makes it hard to assess and measure it on a fixed scale. Measurement of agility of an enterprise has been a major topic of research since inception of agility in 1991. Though some methods have been developed to measure agility, they mainly remain tied to manufacturing industry. As agility is present in all the industries, comprehensive tool to measure it is a necessity in order to determine responsiveness of an enterprise to external turbulences. …
