  1. Project Management • History and concepts • Critical Path Method (CPM) • Original CPM and Modern CPM

  2. History • Egyptian pyramids and sphynx • Bible (Noah, Solomon, et al.) • Roman Empire • Da Vinci, Descartes • Gantt, CPM, PERT • Microsoft, Primavera • IPMA, PMI

  3. Concepts for project • Design: development and specification of a new product or service • Project: sequence of activities or tasks • Project: investment alternatives

  4. Gantt chart

  5. History of CPM 1956: James E. Kelley, Jr. (Du Pont), John W. Mauchly (EMCC), Morgan Walker (Remington) 1957: building a $10M industrial plant 1958: industrial maintenance, reducing MTTR from 125h to 74h 1959: Eastern Joint IRE-AIEE-ACM Conference 1961: Operations Research

  6. CPM concepts Project ≈ network = ∑(events + tasks) Task Starting event Ending Event Assemble spare tire Unfasten nuts Remove spare tire Lift down car Lift up car Change tires

  7. Network logics D D D C C C A A A B B B

  8. Dates and slacks Data: t1 (starting earlier date) t4 (ending later date) Computed: t3 (ending earlier date) = t1 + duration t2 (starting later date) = t4 – duration Total slack = Slack = t4 – t1 – duration Free slack = t3 – t1 – duration task nameduration it1t2 j t3 t4
