Information Risk Management

Revised on: 2015-09-26

Openness, partnering, trust and particularly sharing of information has often been cited as one way to reduce supply chain risk. The more you know, and know early enough, the less surprised you may be about unforeseen developments. However, information sharing has its own set of risks. Information risks management in supply chains: an assessment and mitigation framework by Mohd Nishat Faisal, D.K. Banwet, and Ravi Shankar provides a well-founded theoretical framework for assessing these risks.

This is an updated and extended review of  the Handbook of Transportation Engineering by Myer Kutz (editor) which I have reviewed in a previous post 4 years ago:  Book Review: The Handbook of Tranportation Engineering. While rummaging through references for a journal article I came across an old copy of the chapter on Transportation Engineering in the above book and to my surprise I discovered a recent acquaintance I had forgotten that I already had met 4 years ago: The risk definition by Kaplan & Garrick (1981). For supply chain risk researchers, this risk definition has it all.

Revised on: 2011-07-22

This research essay and literature review investigates some of the gateways to path finding in static and dynamic networks that are listed in present research literature. A selected set of different approaches are highlighted and set in a broader context, illustrating the various aspects of path finding in static and dynamic networks. It is shown that the A* algorithm is the dominant algorithm for solving fastest path problems. A further attempt is made to draw attention to the advances that have been made in path finding in the field of robotics, in order to establish a lateral relation that can form the basis of further exploration and fruitful merger of the two research fields.

Revised on: 2011-05-16

Roads are main arteries of modern society’s infrastructure, contributing heavily to the distribution of goods and persons. GIS provides many helpful applications for ensuring a smooth flow, by aiding design, routing, traffic control and real-time navigation. In essence, a GIS application in transportation is maybe no longer a GIS, but a merger of GIS with Intelligent Transportation Systems or Transport Telematics, where GIS no longer exists as a stand-alone product. This essay will attempt to display the extent of existing GIS applications within road transportation, and critically assess their appropriateness and potential.
