Effect of Risk Priority Number Values for Multiple Effects in Maintenance Optimization
Abstract: In this paper, authors describe an optimization framework for finding optimal maintenance policies in continuous process operations and analyze and quantify the reaction of different variables on optimal maintenance schedules. A necessary idea behind maintenance optimization is that of life-cycle costing, where the total cost of design, building, maintenance, is considered over the entire life span of the system or structure in question. The system’s effectiveness measure is introduced which …

Finite Element Analysis of Steam Turbine Components for Real Life Assessment Studies of 210 MW Steam Turbine
Abstract: The turbine rotor or steam turbine rotor is subjected to temperature variations in short periods of time due to the start and stop cycles of the turbine. This causes sudden changes in the temperature with transient thermal stresses being induced into the turbine rotor. The transient effect is due to the changes in the material properties like density, specific heat and Young’s modulus. The estimate of thermal stresses induced in …

Selection of the Best Statistical Distribution with Multicriteria Decision Making Technique TOPSIS
Abstract: Due to highly competitive global market, the organizations are now forced to focus more on increasing the productivity in their organization. Reliability estimation is necessary to meet that goal. Again for determining Reliability the Distributions of failure datasets are important. But which distribution will best represent that dataset is very important for the decision maker. In this paper an approach is adopted where the decision maker is the central actor …

Optimization of Machining Parameters for Titanium Alloy (Grade-5) Using CBN Tool Insert with Different Nose Radius Using Taguchi Technique
Abstract: In this research paper, focus is on the machinability study of titanium (grade-5) alloy using the CBN cutting tool inserts having nose radius of 0.4 mm and 0.8 mm. Taguchi method provides a simple, systematic and efficient methodology for optimization of the cutting parameters. Taguchi design of experiment approach has been used for planning the experiments and analysis of experimental data obtained. An orthogonal array L27 (313), the signal-to-noise (S/N) …
