We study electoral campaign management scenarios in which an external party can buy votes, i.e., pay the voters to promote its preferred candidate in their preference rankings. The external party’s goal is to make its preferred candidate a winner while paying as little as possible. We describe a 2-approximation algorithm for this problem for a large class of electoral systems known as scoring r...

This article conceptualizes international subcontracting as a type of relational contract formed by buyers and suppliers from different countries, aiming to facilitate the sourcing of product...

This paper presents an exploratory study for identification and quantification of the economic benefits or implications associated with wing cost variations. A hierarchical cost model structure is used to determine life cycle effects of design and manufacturing alternatives for the major structural components of the wing of a High Speed Civil Transport aircraft concept. Preliminary results are ...

This article describes the Delayed Bang Approach for determining the value of risk management alternatives in critical infrastructure security. The discussion includes (1) the need for sustainable risk management (2) the importance of time valuation in evaluating competing loss prevention and loss reduction alternatives, (3) the convergence of deterministic engineering economics, survivability ...

One of the most controversial issues in intrusion detection is automating responses to intrusions, which can provide a more efficient, quicker, and precise way to react to an attack in progress than a human. However, it comes with several disadvantages that can lead to a waste of resources, which has so far prevented wide acceptance of automated response-enabled systems. We feel that a structur...
