Subsequently, multi-response optimization was performed using grey relational and principal component analyses.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Findings<\/jats:title>\n<jats:p>The results revealed that the grey relational analysis along with the principal component analysis is a simple as well as effective method for solving the multi-response optimization problem and it provides the optimal combination of the solar-driven ORC parameters. Further, the analysis of variance was also employed to identify the most significant parameter based on the percentage of contribution of each cyclic parameter. Confirmation tests were performed to check the validity of the results which revealed good agreement between predicted and experimental values of the response variables at optimum combination of the input parameters. The optimal combination of process parameters is the set with A3 (the best fuel mixture in the context of optimal performance is 0.9 percent butane and 0.1 percent pentane by weight), B2 (evaporation bubble point temperature=358\u2009K), C1 (condensation dew point temperature=300\u2009K) and D3 (expander inlet temperature=370\u2009K).<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Research limitations\/implications<\/jats:title>\n<jats:p>In this research, the Taguchi-based grey relational analysis coupled with the principal components analysis has been successfully carried out, whereas for any optimized solution, it is required to have a real-time scenario that may be taken into consideration by the application of different soft computing techniques like genetic algorithm, simulated annealing, etc. The results generated are purely based on theoretical modeling, and, for further research, experimental analyses are required to consolidate the generated results.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title>\n<jats:p>This piece of research work will be helpful to users of solar energy, academicians, researchers and other concerned persons, in understanding the importance, severity and benefits obtained by the application, implementation and optimization of the cyclic parameters of the solar-driven ORC.<\/jats:p>\n<\/jats:sec>","DOI":"10.1108\/gs-03-2017-0006","type":"journal-article","created":{"date-parts":[[2017,6,27]],"date-time":"2017-06-27T07:32:43Z","timestamp":1498548763000},"page":"218-235","source":"Crossref","is-referenced-by-count":19,"title":["Grey relational analysis coupled with principal component analysis for optimization of the cyclic parameters of a solar-driven organic Rankine cycle"],"prefix":"10.1108","volume":"7","author":[{"given":"Deepak","family":"Tiwari","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmad Faizan","family":"Sherwani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad","family":"Asjad","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akhilesh","family":"Arora","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"140","reference":[{"key":"key2020120612455407300_ref001","doi-asserted-by":"crossref","first-page":"2363","DOI":"10.1016\/j.energy.2015.10.092","article-title":"Experimental study of a 1 kw organic Rankine cycle with a zeotropic mixture of R245fa\/R134a","volume":"93","year":"2015","journal-title":"Energy"},{"issue":"1","key":"key2020120612455407300_ref002","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1016\/j.applthermaleng.2013.01.028","article-title":"Comparative performances analysis of low-temperature organic Rankine cycle (ORC) using pure and zeotropic working fluids","volume":"54","year":"2013","journal-title":"Applied Thermal Engineering"},{"key":"key2020120612455407300_ref003","doi-asserted-by":"crossref","first-page":"204","DOI":"10.1016\/j.energy.2014.06.012","article-title":"Selection and optimization of pure and mixed working fluids for low grade heat utilization using organic Rankine cycles","volume":"73","year":"2014","journal-title":"Energy"},{"issue":"3","key":"key2020120612455407300_ref004","first-page":"273","article-title":"Opportunistic actions for subassemblies of a reciprocating compressor: an LCC-based approach","volume":"9","year":"2013","journal-title":"International Journal of Performability Engineering"},{"key":"key2020120612455407300_ref005","unstructured":"Chen, H.
