Determination of Attributes Permanent Index on a Compression Ignition Engine Using Graph Theory Matrix Approach

N. K. Geetha and P. Sekar

In this paper, a systematic method of Graph theory matrix approach is adopted ingeniously to find the optimal combination of operating parameters on a compression ignition engine. For quick appraisal, the Performance attributes digraph is developed to represent the attributes and their relative importance. For one-to-one representation of the attributes, Matrix method is adopted. Permanent function is used to characterize the structure of the matrix. A computer program is developed to find the parameter index from the permanent function. The results of Graph theory matrix approach are compared with other multi attribute decision making methods like Simple additive weighting, Weighted products method and Analytic hierarchy process.
