Abstract
Above and beyond all the trends and developments in computer system design and implementation, are factors related to new applications
domains. We see an eclectic landscape that presents compelling new research, business, and societal challenges-driven by the multidisciplinary
nature of societal problems-at the nexus of food, health, and energy. The next major innovations in computer science and engineering are
likely to come from "intelligent" deployment of human-centric systems that must optimally interact with other manmade and natural systems
with a focus on seamless availability of dynamic decision-making capabilities. Our need to measure, model, communicate, and manage our
vast natural and social enterprise requires a recognition that our physical world is complex and requires a level of adaptation and resilience
that is unprecedented. New creative approaches are essential for handling the problems of scale and complexity envisioned in this future.
Applications, such as, in High Performance Computing, the smart power grid, medical electronics, robotic management and control, all
driven by advanced data-analytics, have spawned a level of complexity where traditional fault-tolerance methods cannot form the backbone
for resilient system design. Assumptions such as occurrence of a single fault in the system, independence of faults, or low hardware and
software interactions are easily foiled in these new settings. This means that a new set of fault models have to evolve and need to be studied
carefully, either by significantly enhancing traditional techniques or by introducing new resiliency methods. Driven by studies of and
observations from current technologies and systems, this talk will present research directions and challenges related to building resilient
applications in several of the new domains.

Title: Reliability and Availability Modeling in Practice

Abstract
Non-state-space solution methods are often used to solve reliability block diagrams, fault trees and reliability graphs. Relatively efficient algorithms are known to handle systems with hundreds of components and have been implemented in many software packages. Nevertheless, many practical problems cannot be handled by such algorithms. Bounding algorithms are then used in such cases as was done for a major subsystem of Boeing 787. Non-state-space methods derive their efficiency from the independence assumption that is often violated in practice. State space methods based on Markov chains, stochastic Petri nets, semi-Markov and Markov regenerative processes can be used to capture various kinds of dependencies among system components. However, the resulting state space explosion severely restricts the size of the problem that can be solved. Hierarchical and fixed-point iterative methods provide a scalable alternative that combines the strengths of state space and non-state-space methods and have been extensively used to solve real-life problems. We will take a journey through these model types via interesting real-world examples.
