On Single Machine Scheduling Problem with Distinct due Dates under Fuzzy Environment

Single machine, distinct due dates, early (lately) machine problem and fuzzy environment closely to the situation faced by '' just in time '' manufacture. This paper attempts to sequence the jobs on a single machine scheduling problem with distinct due dates under fuzzy environment so as to minimize the total penalty cost. This cost is the composition of all the total earliness and tardiness cost. A method to minimize the total penalty cost due to earliness or lateness of job in fuzzy environment is proposed. A numerical example is given in the sake of the paper to support this study.
