In any shop floor the major responsibility of process planning engineer is to process the n number of jobs in m machines within the due date. It can be achieved by optimal sequence of processing the jobs. Many classical heuristics procedures were proposed starting from Johnson s algorithm to find optimal or near optimal sequence for job this research an attempt is made to propose a new heuristic by using Harmonic triangle. Also the new heuristic is compared with fewother popular heuristics like CDS Palmer RA and Gupta Heuristics and the efficacy of new heuristic is analysed.
