Critical Path Method 편집하기 (부분)

==Key Concepts==
*'''Activity Duration (t)''': The estimated time required to complete a task.
*'''Earliest Start (ES)''': The earliest possible time an activity can begin, calculated as:
  ES = max(EF of all predecessors) or 0
*'''Earliest Finish (EF)''': The earliest possible time an activity can be completed, calculated as:
  EF = ES + t
*'''Latest Finish (LF)''': The latest possible time an activity can be completed without delaying the project, calculated as:
  LF = min(LS of all successors) or T
*'''Latest Start (LS)''': The latest possible time an activity can begin without delaying the project, calculated as:
  LS = LF - t
*'''Slack (Float, S)''': The amount of time an activity can be delayed without affecting the overall project schedule. Activities on the critical path have zero slack.
  S = LS - ES = LF - EF
*'''Total Project Duration (T)''': The minimum time required to complete the project, determined by:
  T = max(EF of all activities pointing to the final node)
*'''Variance (V)''': Used to measure the uncertainty in task durations.
