Tabu Search explores activity priority permutations using Adjacent Pairwise Interchanges (API) and short-term tabu memory to find minimal makespan schedules.

Inserts proactive safety buffers using activity inflexibility weights and triangular duration variance (a, m, b) to protect schedules against disruption.
