It seems that my work (mfg. planning, scheduling, and control)
(project management, scheduling and control) fits equally under
7. SIMULATION + model (near) optimization
or
12. WORKFLOW (information and CONTROL)
Bottleneck dynamics is a system for scheduling, reactive scheduling,
or control of manufacturing processes or project management. It
simulates the pocess in a forward fashion, but simultaneously forecasts
vital global parameters such as resource bottlenecks and critical
activities. These forecasts are updated by repeating the simulation
perhaps 5 times until the forecast parameters stabilize. More
specifically the forecast parameters include resource prices, which
provide a quantitative measure of the difficulty of a resource
bottleneck; and activity delay prices, which provide a quantitative
measure of the criticality of a given job activity. Sequencing
priorities are formed as a benefit cost ratio of these prices.
A parallel method, tabu dynamics solves the same problem by a very
fast adaptation of tabu search.
The method has been broadly tested in a number of different contexts
It is thoroughly reported in the text
Heuristic Scheduling Systems, John Wiley, 1993. ISBN 0-471-57819-3.
This text has full bibliographies by a number of topics. However I also
attach some references here.
