Operating Optimization And Global Optimization

Decent Essays

Goldratt describes another two terms of optimization. They are local optimization and global optimization. Optimization includes finding the "best available" values from the system which has a finite capacity along with few constraints. Local optimization has its solution in either maximal or minimal with a neighboring set of candidate solution, whereas a global optimization has its optimal solution among all possible solutions. Since TOC takes into account both interdependence and variation, the system optimum optimization as a whole is not the same as the sum of all the local optima. On combining the dynamic and detail complexity concepts of sense with the global objective versus local objective concepts of Goldratt in a simple 2 by 2 matrix gives us two diametrically opposed concepts. Systemic/global optimum approach is the first combination of dynamic complexity and global optimization. It is under the characterization of drum-buffer-rope, constraints accounting, critical chain, TQM ll, distribution/ marshaling with replenishment and constraint management model for strategy. However, Reductionist/local optimization approach is the second combination of detail complexity and local optimization. It is under the characterization of critical path management, lean production, ISO9000, ISO14000, TQM, kaizen, Six Sigma, MRP II,EPR , mrp, activity based costing, balance scorecard, operations research, scientific management, cost/ absorption accounting. Goldratt introduces the
