Selection of Gear Materials Using MCDM-TOPSIS Approach
Abstract: Materials selection are a key issue in the optimal design of the industrial product. Material selection is a difficult and subtle task because of an immense number of different available materials. Increasing demand for gears in the different field of applications has forced manufacturers to design and develop gears which compete in the global market and satisfy the user requirements as well as environmental conditions. Various attributes of gear materials …

Multi-objective Optimization of Weld Bead Geometry of Micro-plasma Arc Welded Titanium (Ti–6Al–4V) Alloy Sheets Using TOPSIS
Abstract: Titanium alloys are used in the manufacturing of aero engine components for their attractive, combined properties such as lightness, good strength-to-density ratio, corrosion resistance. In the present paper, titanium (Ti–6Al–4V) alloy sheets are butt welded using micro-plasma arc welding. Peak current, base current, pulse rate, and pulse width are considered as weld input parameters and weld bead geometry parameters, namely front width, back width, front height, back height, are considered …

Optimization of Machining Parameters for Nylon 6 Composite in CNC Lathe Using PCA-Based TOPSIS
Abstract: This work investigates the parametric optimization of CNC turning operation for Nylon 6 with principal component analysis (PCA) and technique for order preference by similarity to ideal solution (TOPSIS) based on Taguchi approach. Taguchi’s L16 orthogonal array takes 16 experimental runs to execute the design matrix of turning parameters through PCA coupled with TOPSIS, utilizing relevant experimental data as obtained through experimentation. Turning speed (TS), feed rate (FD) and depth …

Design Optimization of Water Injection Module of Topside Facility of an FPSO
Abstract: Analysis, design and construction of offshores structures are the most challenging tasks in the field of ocean engineering. This work presents a method of designing topside facility of an FPSO by considering all possible environmental loading along with the loading during transportation, lifting and placing. Of all the loads wave loading is the most prominent which has been estimated using a 3D computational fluid dynamics code based on finite volume …

Selection of effective formwork system using multi criteria decision making analysis
Abstract: Formwork is the largest single cost item in constructing cast-in place reinforced concrete structure. This project focuses on analyzing the formwork selection problem based on decisive criteria. The factors affecting the choice of the exact formwork system have been often discussed in literatures but their importances have not been distinctly formulated. Therefore, a survey was conducted to recognize the decisive criteria in the formwork selection problems and ranking of the …
