Question

the central Idea of theory of constraints toc is based on the?​

Answer 1

The theory of constraint (TOC) is based on the assumption that the rate of achievement of objectives by a goal-oriented system (system throughput) is restricted  by atleast one constraint. Reduced ad absurdum's statement is as follows: If nothing prevents a system from achieving higher throughput (that is  more goal units in one unit of time), the throughput will be limitless – which in real life system is impossible. Overall throughput can be improved only by increasing the flow through the constraint

Presuming the goal of a system is articulated and its measurements described, then the steps are

1. Determine the constraints(s) of the system.

2. Decide how the system's constraints(s) can be exploited.

3. Rely on the above decision(s) for everything else.

4. Alleviate the constraints limit(s) of the system

5. If in the previous steps a constraint has been broken, then go back to step 1

Explanation:

• The Theory of Constraint is a method for deciding the most important restricting factor (i.e. limit) to achieve an goal and then improve the limit gradually until it is no longer the limiting factor. The constraint is also called a bottleneck in the production process
• The theory of constraints takes a scientific approach to improvement. This implies that any complex system, as well asmanufacturing processes, consists of numerous, linked operations, one of which acts as a constraint on the whole system (i.e. the "weakest link in the chain" is constraint).
• Some of the appealing aspects of Constraint Theory is that improvement activities are necessarily a priority. The present constraint is the highest priority. TOC provides highly-focused methodologies for rapid change in environments where changes are urgently needed.
