  19. PENYEDIAAN RAJAH RENTETAN • Bahagikan projek kepada beberapa aktiviti. • Tentukan jangkamasa setiap aktiviti. • Kenalpasti perhubungan antara aktiviti-aktiviti:- • - dependent • - parallel • - overlapping • - dulu, kemudian • Lakarkan rajah Rentetan • Hitung masa projek • Hukmum Rangkaian Kerja • Mula - akhir • Tiada nod tergantung • Tiada gelung • Satu anak panah menyambung 2 nod • Dari kiri ke kanan.

  20. Rajah Rentetan (Precedence Diagram) Nod Sumber Nombor aktiviti n Nama aktiviti Jangka masa d TF Masa terluang (float) Masa mula terawal EST LST Masa mula terakhir Masa siap terakhir EFT LFT Masa siap terakhir d i j 1. ESTj = (EFTi) = ESTi - di 2. LFTj = (LSTj) = LFTj - dj 3. EFTj = ESTj + di 4. LSTj = LSTj - di • TFj = LSTj - ESTj

  21. Definision R/R • EST – masa terawal memulakan sesuatu aktiviti. • LST - masa terakhir memulakan sesuatu aktiviti. • EFT - masa terawal siap • LFT - masa terakhir siap Contoh Projek Aktiviti Masa/hari 1 2 3 4 5 6 1 3 2 4 6 1
