ΕΦΑΡΜΟΓΕΣ ΤΗΣ ΜΑΘΗΜΑΤΙΚΗΣ ΑΝΑΛΥΣΗΣ ΕΥΡΕΤΙΚΩΝ ΜΕΘΟΔΩΝ ΚΑΙ ΤΗΣ ΘΕΩΡΙΑΣ ΑΣΑΦΩΝ ΣΥΝΟΛΩΝ ΣΕ ΠΡΟΒΛΗΜΑΤΑ ΠΡΟΓΡΑΜΜΑΤΙΣΜΟΥ ΚΑΙ ΕΛΕΓΧΟΥ ΠΑΡΑΓΩΓΗΣ

THE AIM OF THE THESIS WAS THE STUDY, ANALYSIS AND SCHEDULING OF PRODUCTION SYSTEMS. IN PARTICULAR, A NUMBER OF SCHEDULING PROBLEMS WERE DEALT WITH USING DUE-DATES DETERMINATION METHODS WERE THE DUE-DATES WERE TREATED AS DECISION VARIABLES. RESEARCH WAS ALSO FOCUSED ON IN MODELLING SCHEDULING PARAMETERS WHICH ARE CHARACTERIZED BY IMPRECISION VIA FUZZY SET THEORY. MATHEMATICAL ANALYSIS, ENUMERATIVE TECHNIQUES AND HEURISTIC METHODS WERE USED TO PRODUCE OPTIMAL AND SUBOPTIMAL SOLUTIONS TO A NUMBER OF SINGLE-AND PARALLEL-MACHINES SEQUENCING PROBLEMS UNDER THE APPROACHES DESCRIBED ABOVE.
