“…In this way, it is possible to evaluate S/L ratio for establishing dominant flow between axial and circumferential deformation. This methodology has been tested and confirmed valid for different conditions and materials by several papers, through numerical and experimental method [9,12,20,23,27,28]. [27] extend this work in order to obtain a detailed analytical expression of contact zone.…”

Abstract. After years of purely academic interest and niche applications, today the flow forming process is increasing demand in aerospace, automotive and defense industries. This review surveys academic paper of last fifty years, in order to evaluate the current state-of-the-art for academic and practitioner. Theoretical and experimental approaches are collected and compared by evaluating their prediction models. As a result, several knowledge gaps are identified, for example stress and strain tensors evolutions are not determined for workpiece, due to high computational cost and uncertainty about the correct finite elements approach to adopt. Similarly although, the final microstructure is often evaluated for specific cases, study of its evolution during plastic deformation has not been reported. Residual stress and final material proprieties, such as corrosion behavior, have been not studied numerically or experimentally. Tool path impact and alternative geometries are not deeply explored. Particular attention is given to process experimental optimization and characterization through Design of Experiment, which is still limited to a few papers and sometimes not well developed. The results of this review will help define a research agenda for future developments.

“…Its method is further appropriate for appraising production processes because the necessary number of experiments is reduced meaningfully. The design of experiment by the Taguchi method a ords a simple, e ective, and organized methodology to de ne the best settings [83,84]. Experimental results are changed to a Signal/Noise (S=N) ratio, which means a ratio of an average standard deviation (Taguchi et al [85]).…”

Abstract. A exible Cell Scheduling Problem (CSP) under Time-Of-Use (TOU)electricity tari s is developed in this study. To apply a kind of energy-conscious policy, overconsumption cost of on-peak period electricity, limitations on total energy consumption by all facilities, setup time available on each cell, part defect (pert) percentage, and the total number of Automated Guided Vehicles (AGV) were considered. Additionally, an Ant Colony Optimization (ACO) algorithm was employed to nd a near-optimum solution to the proposed Mixed Integer Linear Programming (MILP) model with the objective of minimizing the total cost of CSP model. Since no benchmark is available in the literature, a lower bound was implemented as well to validate the result achieved. Moreover, to improve the quality of the results obtained by meta-heuristic algorithms, two hybrid algorithms (HGA and HACO) were proposed to solve the model. For parameter tuning of algorithms, Taguchi experimental design method was applied. Then, numerical examples were presented to prove the application of the proposed methodology. Our results were compared with the lower bound, con rming consequently that HACO is capable of nding better and near-optimum solutions.

“…It has been applied in a number of industries and proven to be a critical success in controlling the process quality [16]. Basavarajappa et al [17], Davidson et al [18], Hsu et al [19], and Mahapatra et al [20] utilized Taguchi in analyzing the impacts caused by various parameters. Interactions between empirical factors and responses were discussed.…”

Municipal solid waste (MSW) is generally disposed of at landfills, and is highly attributed to its simplest and cheapest disposal procedures if compared to other approaches such as incineration [1]. Landfills bring negative impact to the environment due to leachate and biogas emission for biowaste [2]. A high amount of biowaste, particularly food waste, can be found in municipal waste. Approximately 45% of municipal solid wastes are organic food waste, followed by inorganic wastes such as plastics and glass [3]. A comprehensive study of food segregation is thus crucial. Segregation of food from waste results in a reduction of organic decomposition arising in a landfill and thus cuts down the generation of leachate. On one hand, the amount of landfill leachate could be lessened with the rare existence of organic matters. On the other hand, the segregated organic substances can be processed independently for methane gas generation, i.e. a green energy for biogas production [4]. Moreover, incineration of these inorganicfree substances produces less residue and toxic gas.Electrostatic separation provides an effective approach to recovering the reusable matter from solid wastes. It has been widely employed in applications involving the dry separation process, e.g. to recover conductors from non-conducting mixtures [5]. The separation process with a roll-type electrostatic separator sorts the charged bodies from the uncharged under an intensive electric field. It serves as an environmentally friendly way for recycling and reusing the resources without negatively impacting the surroundings [6].Pol. J. Environ. Stud. Vol. 24, No. 3 (2015), [1125][1126][1127][1128][1129][1130][1131] Original Research Optimization of Electrostatic Separation AbstractIn this study, the electrostatic separation process was employed to recover biowaste from waste mixtures. The recovered biowaste is a potential source of alternative renewable energy (e.g. biomass energy). Taguchi's methodology of experimental design was used for a robust design of both system and random factors. Robust design attempts to analyze the influence of respective factors towards the separation process and, meanwhile, limits the negative impact of the hard-to-control random factors. The effects of four factors, namely voltage level, rotation speed, water content, and particle size diameter were determined. It was noticeable that voltage level has a maximum effect (39.44%) on effective recovery of biowaste, followed by size diameter, water content, and rotation speed within design range. On the other hand, the minimal middling product was mostly influenced by the voltage level (79.78%). The water content has a negligible effect (0.78 %) if compared to rotation speed and size diameter. This paper concluded the appropriate operational range to have less error from the variations of noise.
