PENJADUALAN PREEMPTION MENGGUNAKAN ATURAN PELEPASAN BERPRIORITI DALAM SISTEM BERGANGGUAN
Keywords:
Penjadualan pengeluaran, Aturan Pelepasan, Sistem BergangguanAbstract
Kertas kerja ini membentangkan kajian yang bertujuan untuk mengemukakan panduan untuk
membantu sesebuah syarikat dalam membuat keputusan terhadap penjadualan yang
bergangguan. Penjadualan semula dicadangkan dengan melakukan 'preemption ', Kajian
dilakukan dengan pendekatan secara heuristik, iaitu dengan membandingkan beberapa kaedah
aturan pelepasan berprioriti. Aturan pelepasan tennasuk Masuk Dahulu Keluar Dahulu (First
Come First Serve ), Tarikh Siap Terawal (Earliest Due Date), Masa Proses Terpendek (Shortest
Processing Time) dan Masa Proses Terlewat (Latest Processing Time) telah digunakan dalam
kajian ini. Hasil kajian ini mendapati bahawa aturan pelepasan Tarikh Siap Terawal lebin
berkesan berbanding dengan aturan lain. Perbandingan dilakukan terhadap beberapa kriteria
penilaian , seperti purata kelewatan (mean lateness), purata masa alir (mean flowtime), 'mean
tardy ', dan 'throughput '.*
