Supply Chain Risk 2011

This is the 2011 version of my annual lecture on Supply Chain Risk, and essentially, it is a selection of the more than 400 articles, books and book chapters I have in my office shelves, and in a way it is a broad literature review of anything connected to supply chain risk.

WCTR 2010

How do Norwegian freight carriers handle the impacts of transportation disruptions? Are “bad” locations synonymous with “bad” logistics? That is the title of my presentation at the World Conference on Transport Research, WCTR 2010, in Lisbon, Portugal, this week. The answer is No.

How Norwegian freight carriers handle disruptions

How are the supply chains of companies located in sparse transportation networks affected by transportation disruptions? What are typical disruptions in certain locations or for certain types of business, and how do businesses and carriers counter supply chain disruptions?

Risks in virtual enterprise networks and supply chains

Conceptual in its approach and drawing from other areas of research, this paper introduces four distinct groups of VENS, namely Constrained, Directed, Limited and Free VEN, and concludes that VEN risk management can and should learn from supply chain risk management.

Er rassikring lønnsomt?

Rassikring av veger har en klar samfunnsøkonomisk nytteverdi, men hvor stor er den? De største gevinstene er knyttet til å unngå omkjøring, skape trygghet og redusere antall ulykker. Hvordan måler man dette i kroner?

Supply Chain Disruptions – Does location matter?

In regions or countries with sparse transportation networks or few transportation mode choices the structure or design of the supply chain, along with the organization and preparedness become important factors in determining if a company has an favorable or a unfavorable location.

Transport Network Vulnerability Metrics

This paper presents a review of road network vulnerability, seeking to synthesize different terminologies and metrics, among which: reliability, vulnerability, resilience, flexibility, robustness, and adaptive capacity.

The vulnerability of road networks in a cost-benefit perspective

A reliable transportation network represents a net benefit to society, and conversely, a vulnerable network represents a net cost to society. Hence, vulnerability ought to be an important parameter for decision-support in cost-benefit analyses, by seeking to establish a link between the terms reliability and vulnerability vis-à-vis costs and benefits.

Reliability and vulnerability versus costs and benefits

Looking beyond the science of vulnerability assessments, this paper discusses some of the network attributes that influence the vulnerability of transport networks, influences that can be described as structure-related, nature-related or traffic-related attributes. The paper introduces vulnerability as a parameter for decision-support in cost-benefit analyses.

Reliability and vulnerability versus costs and benefits

The paper outlines a framework for developing a methodology that to incorporate reliability and vulnerability as parameters for decision-support in a cost-benefit analysis. In doing so, this paper seeks to establish a link between the terms reliability/vulnerability and cost/benefit and seeks to describe reliability and vulnerability in terms of cost and benefit.

A spatial framework for modeling hazards to transportation lifelines

Transportation networks are exposed to a wide range of natural hazards and this study has developed a GIS tool for analyzing these hazards. The primary hazards included in this study are avalanches, landslides, flooding, earthquakes, wildfires, and rockfall. The GIS software used was MFWorks

Corridor Analysis – A timeline of evolutionary development

corridor-modellingLocating a right-of-way for a linear facility such as a pipeline, a transmission line, a railway or a roadway can be a complex problem. Locating a corridor connecting an origin and a destination on a landscape is analogous to identifying a route that traverses a continuous landscape. Thus, corridor analysis is closely linked to shortest-path finding and network analysis in raster GIS, and has evolved along with it. Corridor analysis is essentially a variant of surface analysis, but can also be viewed as a site selection problem where an optimal contiguous and elongated site is sought.

Fastest path problems in dynamic transportation networks

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.
