A methodology inspired by a game-theoretic view of the on-line control
problem for job-shops is developed which allows the use of static off
-line schedules in uncertain environments, and the explicit incorporat
ion of deterministic and stochastic information concerning future dist
urbances. A discrete event dynamic system representation is used to fo
rmulate the control problem. The control objectives are to minimize ex
pected makespan and deviations from an off-line schedule. Computationa
l tractability is achieved through a graph-theoretic decomposition of
the job-shop scheduling problem, the development of fast rescheduling
heuristics, and efficient sampling of future events. A heuristic searc
h algorithm is developed for problem resolution. Experimental results
show that the methodology significantly outperforms existing control m
ethods such as 'total rescheduling' and 'right-shift.' Most importantl
y, the control methodology demonstrates consistent performance and sma
ll CPU time requirements throughout the tests.
