this paper proposes an optimal power flow (opf) algorithm by direct load control (dlc) programs to optimize the operational cost of smart grids considering various scenarios based on different constraints. the cost function includes active power production cost of available power sources and a novel flexible load curtailment cost associated with dlc programs. the load curtailment cost is based ...

The present paper aims to propose a fuzzy multi-objective model to allocate order to supplier in uncertainty conditions and for multi-period, multi-source, and multi-product problems at two levels with wastages considerations.  The cost including the purchase, transportation, and ordering costs, timely delivering or deference shipment quality or wastages which are amongst major quality asp...

This report is intended to facilitate dialogue between engineers and optimizers about the eeciency of Taguchi methods for robust design, especially in the context of design by computer simulation. Three approaches to robust design are described: 1. Robust optimization, i.e. specifying an objective function f and then minimizing a smoothed (robust) version of f by the methods of numerical optimi...

In this research, a new cost-effective carbon source of medium was provided in terms high-efficiency growth from Arthrospira maxima. Sugarcane molasses used two different modes (alternative and additive) at four concentrations (0, 0.5, 1.0 1.5 gL-1) to determine the effect versus its standard Zarrouk’s (NaHCO3). The experimental results were analyzed by Taguchi L8 method as statistical techniqu...

The challenge of recent machining industries is reduce lead time and increase production rate in order to maintain their competitiveness. This paper investigates the machinability of mild steel in turning process perform on conventional lathe machine. Twoparameters like tool rake angle and feed are varied to investigate their effect on material removal rate. An attempt has been made to model th...

The multiobjective design of digital filters using the powerful Taguchi optimization technique is considered in this paper. This relatively new optimization tool has been recently introduced to the field of engineering and is based on orthogonal arrays. It is characterized by its robustness, immunity to local optima trapping, relative fast convergence and ease of implementation. The objectives ...

This paper presents the solution of economic power dispatch (EPD) through the application of genetic algorithm (GA) and the taguchi method. The economic power dispatch is a non-linear optimisation problem with several constraints. The objective of the proposed genetic algorithm combined taguchi method is to choose the most efficient combination of Pc (crossover probability), Pm (mutation probab...

Design of experiments (DOE) methods are very commonly used for process validation. In this study, we employed the Taguchi approach in order to develop an optimal process for the maximization of oscillatory shear stress environments (OSS). OSS has been associated with increase in cellular activity and has been linked to healthy gene expression and tissue formation. Therefore, OSS may be a key fa...

By the grey-based Taguchi methods, this study attempts to analyze the process parameters pertinent to the multiple performance characteristics of linear motion guides and obtain the multiple performance characteristics of the noise level, push force value and horizontal combination precision of the linear motion guide with multiple qualities. Optimal process parameters are determined by using t...

Dolph-Chebychev arrays are known to exhibit the best compromise between sidelobe level and directivity. However, they place a constraint on the null locations. Any attempt to impose nulls or get them deeper will impact the directivity/sidelobe level trade-off. In this work, null placement in Dolph-Chebychev arrays through element position perturbation is carried out based on Taguchi method whil...
