		Theory of constraints (TOC) is a body of knowledge on the effective management of (mainly business) organizations, as systems.
		All real-world systems have at least one constraint; otherwise they would be capable of infinite throughput, which is clearly impossible.
		A major implication of this is that managing a complex system or organization can be made both simpler and more effective, by providing managers with a few specific areas on which to focus -- maximizing performance in the areas of key constraints, or "elevating" the constraint (making it less constraining).

	Cadence Constraint Manager Elevates Rules-Driven High-Speed PCB Design to Next Level
		This first-time direct integration of a constraint management system with different design tools is a radical departure from the traditional approach of managing high-speed design constraints as net-level database properties.
		The Constraint Manager enables designers to group all of the high-speed constraints for a collection of signals to form an electrical constraint set (ECSet), that is then associated with those nets to manage their actual implementation.
		Hierarchical constraint management means that the same constraints can be applied to a collection of signals and overridden on a case-by-case basis where appropriate.

	2 A Framework For Intergrating Engineering Applications
		The constraint management objects derived from the objects and methods are used for the constraint management.
		All the operations for the management and the resolution are based on the constraint management object in the database.
		From the integrated constraint management system's view point, this approach is inefficient in that each application must translate its data and associated rules through the constraint checker.

	NEXT-LINK SBD Proposal page
		A key requirement for both managing the development process and for maintaining and modifying the product over its life is the ability to capture decisions and their supporting rationales and to automatically propagate the effects of those decisions in the context of changing requirements, objectives, and constraints.
		A ``constraint manager" or broker is therefore needed to map between between constraints as expressed in the design and as represented by CSP solvers and to identify which CSP solver(s) are can most effectively deal with which sets of constraints.
		Constraints change during the life of the project and it is problematic to track them and their effect on the project process and design.

		Constraints must be prioritized as to their impact on the goal.
		Just because a rule or policy was instituted to help exploit a constraint does not mean that it should not go unchallenged once the constraint has been elevated to a non-constraint.

	7 Constraint Management in an Engineering Design System
		To manage the user-defined integrity constraints, we employ the HVC as the unit of constraint management which includes creation, update, deletion, and conflict resolution of constraints.
		Compared with other systems that support only design data without its constraints, the constraint management system provides data with its constraints concerning ergonomic design so that heterogeneous applications may share the data and constraints and be integrated at the semantic level as mentioned in Section 1.2.
		The constraints on a control and constraints on grouping controls are specified with triggers in the database, and the constraints among controls are specified with the CONSTRAINT constructors introduced in Section 7.1.3.

		We teach about the tools of constraint management and how to locate the actual or "real" constraints of your operation.

		Constraint Management efforts can immediately resolve extremely negative effects from machine, labor, and process inefficiencies, and have the ability to fund your entire transition to Lean through substantial increases in throughput.

	Chapter 17
		Constraint management provides a focusing framework for the management of complex business systems by focusing on the most important component of those systems: the constraint.
		Constraint management employs a five-step process to obtain the most from a constrained system by first identifying the constraint, then exploiting it, and then subordinating other business decisions to the exploitation of that constraint.
		Constraint management, covered in Chapter 17, includes a very effective approach to using inventory buffers to protect a constraint from being idle.

		Each constraint has an interest in some subset of the variables, and a utility that varies depending on the assignments to those variables.
		Constraint optimization seeks assignments to the variables that maximize the sum of the utilities of all the constraints.
		In this case, generators, grids, and loads are constraints, and the power flows among them are the variables to which assignments are required.

	The CCM Constraint Management Methodology
		Therefore, a computer-supported constraint management methodology that automatically detects violations early in the design process, provides useful violation notification to guide redesign efforts, and can be integrated with conventional CAD software can be a great aid to the designer.

		After constraint evaluation, the conflict information is returned to the design process manager.

		To exploit (make maximum use of) the constraint in terms of Throughput, we have to release the correct work into the system at the proper time to never starve the constraint, and also to not overload it.
		Overloading the constraint (that is, producing more than it can process) creates excess in process inventory (piles of incomplete work in front of the constraint).

	Frank Patrick's Focused Performance Weblog
		Constraint Management suggests instead that projects only be launched at a rate that can be handled by the organizational system, and as its surrogate, by the system’s constraining resource.
		Once it is known when the constraint can take on a new project, it’s a simple matter of placing it there in the calendar, perhaps with a bit of buffer to avoid cross project impacts at the constraint, and examining the resulting schedule to determine where it’s appropriate to start the upstream activities.
		Instead, the means of managing the constraint for growth of throughput starts with stabilizing the system so that the extra capacity upstream of the constraint assures that the constraint is not starved for work.

	What is Constraint Management? (Site not responding. Last check: 2007-10-14)
		Constraint management (CM) is a way of planning, organizing, evaluating and controlling complex systems.
		The roots of constraint management lie in the Theory of Constraints (TOC), conceived in the 1980s by an Israeli physicist named Eliyahu M. Goldratt.
		One of the central concepts in constraint theory, and the management prescriptions that follow from it, is the idea that complex systems are analogous to chains: the entire chain is no stronger than its weakest link (the system constraint).

	Chawathe, S.; Garcia-Molina, H.; Widom, J.: Flexible Constraint Management for Autonomous Distributed Databases (Site not responding. Last check: 2007-10-14)
		In an autonomous environment that does not support locking and transactional primitives, it is not possible to make "strong" guarantees of constraint satisfaction, such as a guarantee that a constraint is always true or that transactions always read consistent data.
		Using our framework it will be possible, for example, to guarantee that a constraint is satisfied provided there have been no "recent" updates to pertinent data, or that a constraint holds from 8am to 5pm everyday.
		Such weaker notions of constraint satisfaction requires modeling time, and consequently, time is explicit in our framework.

		For the implementation of the constraint manager module we rely on an existing constraint solving engine, which is wrapped into adapting code to interface it with the other DiaGen modules.
