Cycles optimization: The equivalent annuity and the NPV approaches

open access: closedInternational Journal of Production Economics, 2001
Abstract The paper discusses the use of a generalized version of the equivalent annuity principle, which takes into account interest rate fluctuations over time. When dealing with applications over a sequence of cycles, e.g. plant replacement ones, the equivalent annuity is usually defined with reference to each single cycle or to the whole sequence.

Demagnetization-Fault Reconstruction and Tolerant-Control for PMSM Using Improved SMO-Based Equivalent-Input-Disturbance Approach

IEEE/ASME transactions on mechatronics, 2022
A demagnetization fault not only degrades the performance of a permanent magnet synchronous motor (PMSM) drive system, but also may even cause the irreversible demagnetization.

An Ultra-Wideband Multilayer Absorber Using an Equivalent Circuit-Based Approach

IEEE Transactions on Antennas and Propagation, 2022
An ultrawideband (UWB)absorber designed by equivalent circuit model (ECM) is presented in this article. The structural parameters of multilayer absorbers were calculated for full-wave simulation so as to verify the accuracy of this method. The simulation

Real-Time Valuation of Large Variable Annuity Portfolios: A Green Mesh Approach

North American Actuarial Journal, 2020
The valuation of large variable annuity (VA) portfolios is an important problem of interest, not only because of its practical relevance but also because of its theoretical significance. This is prompted by the phenomenon that many existing sophisticated

High Performance Energy Selective Surface based on Equivalent Circuit Design Approach

IEEE Transactions on Antennas and Propagation, 2021
This paper presents a detailed circuit analysis of Energy Selective Surface (ESS), which adaptively protects electronic equipments from high-power microwave (HPM) thanks to its self-actuated response and nonlinear transmission feature.
