Flexibility and safety are often considered conflicting concepts because flexibility implies dealing with changing requirements that can, in turn, produce unpredictable and possibly unsafe operating scenarios. Therefore, some in the automotive and avionic system design industry believe that a safety-critical system implies a fully static system in which all operating conditions are completely d...

This paper deals with the prediction of chaotic time series by using the multi-stage fuzzy inference system and its application to the analysis of operating flexibility. Multi-national corporation obtained by shifting manufacturing plants located in different countries is denoted as operating flexibility. Even though the operating flexibility is optimized by the stochastic dynamic programming u...

An open operating system provides a high degree of programming flexibility and efficiency. At the same time, it generally requires that all programs be written in a single language, and provides no protection other than that which is available from the compiler. These limitations may be tolerated by the user of a personal computer, but they become unacceptable on a workstation that must run unt...

Symmetrical nature of mean of electrical signals during normal operating conditions is used in the fault detection task for dependable, robust, and simple fault detector implementation is presented in this work. Every fourth cycle of the instantaneous current signal, the mean is computed and carried into the next cycle to discover nonlinearities in the signal. A fault detection task is complete...

We consider an optimal investment problem when a firm such as an electric power company has the operational flexibility to expand and contract capacity with fixed cost. This problem is formulated as an impulse control problem combined with optimal stopping. Consequently, we obtain optimal investment timing, optimal capacity expansion and contraction timing, and the investment value. We also sho...

The demands on today’s products have become increasingly complex as customers expect enhanced performance across a variety of diverse and changing system operating conditions. Reconfigurable systems are capable of undergoing changes in order to meet new objectives, function effectively in varying operating environments, and deliver value in dynamic market conditions. Research in the design of s...
