Capacity constraint resource system

TOC should have widespread application in supply chain linkage building. The theory of constraints was introduced in Section 27.4. In formulating this theory, Eli Goldratt and Robert Fox observed that a production system could produce no more than its capacity constraint resource, or CCR. They use this principle as a foundation for what they call the drum-buffer-rope (DBR) way. ... 

The theory of constraints (TOC) is a management philosophy developed by Goldratt (1992). The theory is that the output of an organization is limited (constrained) by internal resources, market factors and by policy. Resource constraint means not enough resources to meet demand, market constraints mean capacity is more than the market demands, and a policy constraint (i.e. a policy of no overtime) can limit output. TOC tries to improve system performance by focusing and eliminating constraints. In service operations where it is often difficult to quantify the capacity constraint, TOC can be very useful. For companies that employ skilled workers and for many service organizations the constraint is often the time of one or a few key employees. The key steps in this process are ... 

The Interactions between availability of resources, carbon gaining capacity, and the allocation of carbon to plant functions, Including chemical defense, will obviously differ among environments. We examine a particular system, the temperate deciduous forest, to Illustrate the nature of the constraints on chemical defenses Imposed by limitations on carbon gain.
