Pliability and Viable Systems: Maintaining Value Under Changing Conditions

Value and Liquidity under Changing Market Conditions

Papers studying the liquidity of a market tend to focus on decisions involving the trade-off between the selling price and the time-till-sale for a given set of market conditions. This paper characterizes market conditions using a price-probability locus; a change in market conditions is some combination of changes in the level and/or slope of this locus. I show how the effect of either type of...

Managing the Impact of Change through Survivability and Pliability to Achieve Viable Systems

As technology improves, traditional systems are being interconnected into larger systems of systems (SoS) that operate in diverse contexts, where numerous perturbations exist that threaten the ability of the SoS to deliver acceptable value to its diverse set of stakeholders. Furthermore, the systems of systems themselves can change form voluntarily or involuntarily in response to contextual var...

Maintaining High-Bandwidth Under Dynamic Network Conditions

The need to distribute large files across multiple wide-area sites is becoming increasingly common, for instance, in support of scientific computing, configuring distributed systems, distributing software updates such as open source ISOs or Windows patches, or disseminating multimedia content. Recently a number of techniques have been proposed for simultaneously retrieving portions of a file fr...

Novelty Detection under Changing Environmental Conditions

The primary objective of novelty detection is to examine a system’s dynamic response to determine if the system significantly deviates from an initial baseline condition. In reality, the system is often subject to changing environmental and operation conditions that affect its dynamic characteristics. Such variations include changes in loading, boundary conditions, temperature, and moisture. Mo...
