The role that supervisory control or upper-level multi-objective optimization can play in total engine control is considered. This involved the control of an SI engine for a combination of air-fuel ratio, torque, fuel consumption and residual gas fraction. The upper level optimization algorithm, based on Model Predictive Control principles, makes use of a ‘reference model.’ This is constructed as...
Exchange rate forecasting has become a popular research topic in recent years because the problems of the forecasting model selection and the improvement on forecasting accuracy are not easy to be solved. In this study, we employ a swarm intelligence method called Interactive Artificial Bee Colony (IABC) and use nine macroeconomic factors as the input for the exchange rate forecasting. The sliding...
An ordinal optimization (OO) technique in conjunction with a particle swarm optimization (PSO) method is presented in this paper to solve a feeder reconfiguration problem that aims to maximize distributed generation (DG) penetration in an existing distribution network. A set of good enough solutions obtained from crude models used in OO approach are taken as the initial population of particles for...
This research adduced process capability indices of quality management to develop a new performance appreciation method. It constructs the capability of a larger-the-better process with process capability index. Not only do investment satisfied capability index (ISCI) and investment satisfied degree evaluates efficiently when construct lower limit of confidence by investment performance indices, but...
