Formulas
PERT Expected Duration & Variance:
$$t_e = \frac{a + 4m + b}{6},\quad \sigma^2 = \left(\frac{b-a}{6}\right)^2$$Forward Pass: $ES_j = \max_i(EF_i)$, $EF = ES + t_e$
Backward Pass: $LF_i = \min_j(LS_j)$, $LS = LF - t_e$
Total Float: $TF = LS - ES = LF - EF$
On-Time Probability:
$$Z = \frac{T - \sum_{CP} t_e}{\sqrt{\sum_{CP} \sigma^2}},\quad P = \Phi(Z)$$
CAE Integration: Schedule management for mesh generation, solver execution, and post-processing / Design review (DR) scheduling for aerospace and automotive development / Production preparation process optimization for new product launches. Concentrating resources on the critical path improves on-time delivery rates.
