It is important to distinguish to between criticality and vulnerability when assessing the importance of the road and highway network. Collectively, these factors are an indication of the conditions, concerns, consequences, and capabilities that might cause an operating agency to label an asset “critical.”
This book is clear and concise, to the point, and constantly switching between risk management in general, supply chain risk, and business continuity, always seeing the whole picture
This is a philosophical essay on transportation vulnerability, where three fields or subjects are brought together : engineering (reliability and vulnerability), economics (cost and benefits) and politics (decision making).The research essay aims at taking reliability and vulnerability into the realm of cost-benefit analysis to serve as decision support.
The paper defines the concept of vulnerability as it applies to production systems and is built around three concepts: A taxonomy of vulnerability factors as a basis for or guideline in establishing scenarios.
An input/output model to describe production systems.
A two-step vulnerability analysis for productions systems.
To make the supply chain more resilient, businesses need to do more than just think about the problem; they must prepare to act effectively, and find the optimal tradeoff between disruption costs and mitigation costs.
This excellent book by Donald Waters offers a comprehensive overview of many important issues in managing supply chain risk. More than 15 case studies and a straightforward hands-on practical approach make this book an enjoyable read. I almost forgot that I bought this book as a text book.
To think the unthinkable, to plan for the unthinkable is maybe not what is most on people’s mind and more often than not, it is only after a crisis that our thinking shifts. Then however, it may be too late.
The increase in generalised travel costs weighted by the satisfied or unsatisfied demand when network links are closed is used as a measure of vulnerability for a case study in Northern Sweden, and applied to the terms of importance and exposure.
As our infrastructure and organisations become ever more networked and interdependent there is a growing need to focus on managing overall system risk. In particular, there is a need to focus not only on the vulnerability of our systems to failure, but also on our ability to manage and minimise the impact of any failures.
Supply chain vulnerability is an important business issue, but little research has been undertaken into supply chain vulnerabilities. Recently I came across a report on Supply Chain Vulnerability published as early as 2002 by the Cranfield University.
A typical supply chain consists of a company with incoming raw materials from an upstream supplier and outgoing products to a downstream customer.
A supply chain is characterized by its locational and organizational design.
There are many potential disruptions to a supply chain.
The potential disruptions may or may not influence locational decisions.
The impact and severity of disruptions depends on both locational vulnerability and organizational adaptability.
Reliability and vulnerability are important elements in ensuring a smooth 24/7 operation of transportation networks, road networks in particular, and cost-benefit analyses of transportation projects should take this into account. One way of doing this is to say that investments in improved reliability constitute a cost and thereby saved disruption costs constitute a benefit.
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.
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.
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.
Transportation networks like freeways and interstate highways are the main backbone of modern society. Consequently, the reliability or vulnerability of any transportation network is thus a decisive factor not only in terms of market outreach and competition, but also in terms of continuity, to ensure a 24/7 operation of the community we live in.
