Abstract: Methods and apparatus for asset management are provided. The apparatus, for example, a processor to receive an input from a user via an input/output device, the input including information for a plurality of assets maintained by the user; decompose a main problem into multiple sub-problems; independently solve each of the multiple sub-problems to determine corresponding multiple sub-solutions; recombine the corresponding multiple sub-solutions into a solution to the main problem; calculate an intervention schedule for each asset of the plurality of assets based on the solution; and upon receiving a request from the user, output the intervention schedule via one of a display of the input/output device or remote electronic device in communication with the asset management apparatus.

Abstract: Automated systems and methods for use in managing collections of capital assets determine optimal replacement dates for assets based on total cost curves. Replacement dates are adjusted within ranges that avoid unacceptable risk of unmonetizable failures to satisfy constraints. Priority in adjusting replacement dates is determined based on deferral cost metrics which may be based on the total cost curves.

Abstract: An active rectifier including an anode terminal, a cathode terminal, a MOSFET operable to allow current flow from the anode to the cathode, a voltage sensing circuit operable to sense the voltage between the anode and cathode terminals and a gate drive circuit responsive to the voltage sensing circuit and operable to drive the gate of the MOSFET such that the MOSFET conducts when the voltage at the cathode terminal is less than that at the anode terminal and such that the conduction occurs substantially in the linear operating region of the MOSFET.
