Application of the Taguchi based entropy weighted TOPSIS method for optimisation of diesel engine performance and emission parameters

Abstract

Diesel engines convert chemical energy into mechanical energy generally with low efficiency. However, if these engines are operated at optimum levels of input parameters, they can produce power more efficiently with minimum harmful exhaust emissions. The current research work is carried out with an aim to determine these optimum levels of the input parameters. Four input parameters were selected and their optimum combinations were determined using Taguchi based technique for order of preference by similarity to ideal solution (TOPSIS) coupled with Entropy Weight method. Taguchi's L 25 orthogonal array was adopted to perform the experiments. All the test runs were carried out in random manner with three replicates of each to improve the accuracy of the experiments. The preference values (relative closeness of the distinct alternative to the positive ideal solution) predicted by Taguchi method and the values obtained by regression analysis, at optimum input parameter settings were compared and a good relationship was found between them.

“…However, Pi value cannot be determined by performing only one experiment. Therefore, to determine the experimental values of Pi at optimum combination, regression analysis was performed [61]. Regression equation thus obtained for Pi is given in Eq.…”

A Hybrid Multi-Objective Optimization Method Based on NSGA-II Algorithm and Entropy Weighted TOPSIS for Lightweight Design of Dump Truck Carriage

“…Information entropy can be used to describe the degree of disorder of the system. The smaller the information entropy of a certain index is, the greater the information content of the index is, and the higher the weight should be in the evaluation [33]. Thus, the entropy method is adopted to determine the weight coefficient of each evaluation index.…”

Research on Evaluation Method of Freight Transportation Environmental Sustainability

“…In recent years, the research were mainly focused on the selection of suppliers and order distribution [17], enterprise product quality evaluation [18], soft power analysis [19], community sustainability assessments of public rental housing [20], user behavior analysis [21], social development analysis [22], and social impact evaluation [23]. In the research of energy and related fields, scholars used the entropy weight method to optimize the design of the hybrid energy system [24], comprehensively evaluate power grid planning [25], evaluate park energy utilization [26], a comprehensive risk assessment of electricity [27], calculation of petroleum standard indicators [28], and in a diesel engine emission evaluation [29]. In traffic and transportation, scholars have used the entropy weight method to evaluate the transportation of dangerous goods [30], and analyze road traffic conditions [31].…”
