Workshop 5b - Pi Day Pie (Critical Path Analysis)

Have you got time to bake a pie, wash up and eat before meeting your friends at the cinema? What time do you need to start cooking and how long will each step take? This workshop uses critical path analysis to solve problems.

Curriculum areas covered:
GCSE:
apply the four operations to integers
use standard units of time, using decimal quantities where appropriate
A Level:
Interpret and communicate solutions in the context of the original problem.
Understand, interpret and extract information from diagrams and construct mathematical diagrams to solve problems, including in mechanics.
A Level: Decision/Discrete maths
Completion of the precedence table for a given activity network.
Construct, represent and interpret a precedence (activity) network.
Use critical path analysis and be able to interpret outcomes, including implications for criticality.
Determine earliest and latest start and finish times for an activity network.
Identify critical activities, critical paths and the float of non-critical activities.
This pack includes:
 Cover Sheet
 Student Worksheet
 Presentation
 Teacher Notes
 Diagram cards

The OR technique featured in this workshop is critical path analysis. Critical path analysis is a popular project management tool, it shows the shortest time needed to complete a project and factors in which tasks are dependent on others. For more information visit our website: theorsociety . com
