Theory of Constraints (TOC) - answer A holistic management philosophy developed Dr.
Eliyahu M. Goldratt that is based on the principle that complex systems exhibit inherent
simplicity. Even a very complex system comprising thousands of people and pieces of
equipment can have, at any given time, only a very, very small number of variables—
perhaps only one, known as a constraints—that actually limit the ability to generate
more of the system's goal.
Bottleneck - answer A facility, function, department, or resource whose capacity is less
than the demand placed upon it.
Throughput - answer The rate at which the system generates "goal times" Because
throughput is a rate, it is always expressed for a given time period.
cycle time - answer1) In industrial engineering, the time between completion of two
discrete units of production. For example, the cycle time of motors assembled at a rate
of 120 per hour would be 30 seconds.
2) In materials management, it refers to the length of time from when material enters a
production facility until it exits.
Synonym: throughput time.
Capacity-constrained resource (CCR) - answerA resource that is not a constraint but
will become a constraint unless scheduled carefully. Any resource that, if its capacity is
not carefully managed, is likely to compromise the throughput of the organization. (Also
called capacity constraint resource).
Split Lot - answerA manufacturing order quantity that has been divided into two or more
smaller quantities, usually after the order has been released. The quantities of a split lot
may be worked on in parallel, or a portion of the original quantity may be sent ahead to
a subsequent operation to be worked on while work on the remainder of the quantity is
being completed at the current operation. The purpose of splitting a lot is to reduce the
lead time of the order.
drum-buffer-rope (DBR) - answerThe theory of constraints method for scheduling and
managing operations that have an internal constraint or capacity-constrained resource.
Drum Schedule - answerThe detailed production schedule for a resource that sets the
pace for the entire system. The drum schedule must reconcile the customer
requirements with the system's constraint(s).
