Expected range of the output response for the optimum input parameters utilizing the modified Taguchi approach

摘要

Purpose - Scatter in the outcome of repeated experiments is unavoidable due to measurement errors in addition to the non-linear nature of the output responses with unknown influential input parameters. It is a standard practice to select an orthogonal array in the Taguchi approach for tracing optimum input parameters by conducting a few number of experiments and confirm them through additional experimentation (if necessary). The purpose of this paper is to present a simple methodology and its validation with existing test results in finding the expected range of the output response by suggesting modifications in the Taguchi method. Design/methodology/approach - The modified Taguchi approach is proposed to find the optimum process parameters and the expected range of the output response. Findings - This paper presents a simple methodology and its validation with existing test results in finding the expected range of the output response by suggesting modifications in the Taguchi method. Research limitations/implications - Adequacy of this methodology should be examined by considering the test data on different materials and structures. Originality/value - The introduction of Chauvenet's criterion and opposing the signal-to-noise ratio transformation on repeated experiments of each test run will provide fruitful results and less computation burden.
