Selecting the right suppliers for a supply chain is important as it can have great significance on the operating performance of the supply chain. The supplier selection problem can be quite complex as it usually involves numerous variables and uncertainties, which frequently come in the form of disruptions. This paper examines the existing approaches for supplier selection with focus on their advantages...
An efficient decomposition approach is applied to the optimization of a beer fermentation reactor modeled with a set of strongly nonlinear differential equations. The optimal cooling rate policy is developed to maximize the product concentration within a minimum batch time. A special property of the system is the existence of a state variable inequality constraint. The optimal control problem is solved...
Online identification of aircraft parameters allows more intelligent control methods to be adopted. However, performing real flight tests during the development process of an identification algorithm is very difficult. This paper presents a real-time simulation system for online identification experiments that uses double computers with MATLAB and X-Plane flight simulation software. The computers...
It is possible to prevent collapse of whole post-fault power system, which is in unstable condition, by determining the splitting boundary to calm down system oscillation. A fast splitting boundary-searching method for power system controlled islanding is presented in this paper. The aim of this method is that the generation load imbalance in each island is as small as possible. The method contains...
This paper presents a physical description of two specific aspects in drain-extended MOS transistors, i.e., quasi-saturation and impact-ionization effects. The 2-D device simulator Medici provides the physical insights, and both the unique features are originally attributed to the Kirk effect. The transistor dc model is derived from regional analysis of carrier transport in the intrinsic MOS and the...
The study of various stability-control methods for a transmission system indicates that the reclosing time of a transmission line has a distinct influence on system stability. And there is an optimal reclosing time (ORT) for all transmission line faults. Utilizing the transient energy function (TEF) with classical models considered, the ORT setting computation method is proposed. This paper shows...
