Activity Networks, Dummy activities and Crashing Example: 2024 VCE GM Exam 2
Overview Master one of the trickiest modules in the VCE General Mathematics Exam 2 with this comprehensive, step-by-step worked solution guide. Dedicated to Question 15 of the 2024 paper, this free 5-page PDF breaks down activity networks, float times, dummy activity placement, and cost-efficient crashing so you can gain maximum exam marks.
What's Included
Annotated Network Diagrams: Clean, hand-annotated network diagrams showing forward and backward scanning values (EST and LST) at every node.
Critical Path & Float Analysis: Step-by-step working out to determine the critical path (A-C-H-J) and calculate activity float times (e.g., Activity E with a 3-week float).
Dummy Activity Breakdown: A clear, logic-driven method to spot LST table discrepancies and correctly position directed dummy edges.
Examiner Insights & Pitfalls: Key notes highlighting common student mistakes, such as missing arrowheads or labels on dummy edges.
Full Crashing & Optimization Grid: A complete pathway-by-pathway reduction table showing how to systematically crash activities under constraints to find the minimum project cost ($50,000).
Key Topics Covered
Forward and Backward Scanning
Critical Path Determination
Float Time Calculations (Float = LST - EST)
Dummy Activity Identification & Construction
Activity Crashing & Cost Optimization
Who Is This For?
VCE General Maths Students: Perfect for revision before SACs or final exams to master network flow calculations and examiner expectations.
Maths Teachers & Tutors: A ready-to-use visual exemplar and breakdown for classroom instruction or tutoring sessions.
