theory of constraints

The current research is to provide an applicable and suitable model for throughput accounting of the propulsion system of the technology industry based on the theory of constraints. System throughput accounting is a dynamic, aggregated, principled and comprehensive approach to management accounting that provides information to support managers' decision-making in order to optimize the organization. The methodology used in this research is qualitative. in which the foundation data grand theory method is used. using the opinions of subject experts and interviewing 14 experts in this field and using the snowball method until reaching the theoretical saturation stage in order to identify the effective factors in developing the desired research model using open, axial and A choice has been made. In the end, the results of this research lead to the presentation of a model for system throughput accounting, which is developed and presented in the direction of the drivers of the technology industry, based on the theory of limitations, as well as the conceptual model of the research. From the results of the current research that used the Strauss and Corbin method, there are six categories including the main category; Causal conditions; Intervening conditions; the ruling platform; Strategies and consequences were extracted in most of the relevant components.

The Theory of Constraints (TOC) is one of the techniques of decision making in strategic management accounting(SMA) and theorizing of performance evaluation With a systematic approach to the firm and in line with the strategy of cost leadership,thinks with the growth strategy.The use of TOC in the explanation of Economies of Scale (ES), which are the concepts of management economics, Can lead to system thinking in the banks.The concept of ES refers to the change in the production of products for the change in inputs and the benefits of lowering costs as a result of increased volumes of output.In this research, ES of 17 banks of the country during the period of 1386-1396 was calculated based on the TOC approach. Using the Translag Model and the Frontier 4.1 Software,The average ES of the banks of the country based on the TOC were estimated 0.16.The findings of this research indicate that the banking system of the country has a scale of economies,But it does not fully exploit the potential and continues to operate below the potential capacity,Which is more severe than the Theory of Constraints.Also, according to the results of the research, there is a reverse relationship between the ratio of equity to assets and Economies of Scale of banks using the Theory of Constraints (ES-TOC); As equity increases, the amount of economies is reduced to a scale, and Considering the smaller one of its being, banks will continue to be in a position to economies on a larger scale and increase potential capacity.

Intense competition in the world is caused success be short lived. Therefore organizations for guarantee theirs revive should have continuous improvement and go to new approach for evaluating the performance. In this paper major technique of Throughput Accounting and its power for change in accounting procedures is analyzed. Throughput Accounting is application theory of constraints in accounting and financial. Generally Throughput Accounting invented for using in manufacturing but it can use in industries such as software. Throughput Accounting Phrase is Derivative from financial measuring specific methods that used for calculating and decision making. Throughput Accounting provides a different method of measuring. It does not use cost of production and eliminates Management incentive to create additional surplus production.

Financial performance has always been considered by researchers. Finding Indexes that proven theoretically and empirically is a great challenge in this area. One of the new models of performance evaluation is “Throughput Accounting” based on the theory of constraints. This theory provides measures aims to generate cash in the present and future with focus on drum (bottleneck) management. There seems non-performing loans to be the major banking system bottleneck that affects banks performance through multiple channels. Due to the different nature of banking operations, it is expected that Throughput Accounting approach can be more efficient to show non-performing loans consequences.This study examines the relationship between performance evaluation criteria based on theory of constraints and the rate of non-performing loans. Other performance evaluation criteria (include traditional, economic and) have been examined to choose the most appropriate repressors. We use several panel regressions for financial data of 19 Iranian banks during 2006 - 2010. Then the explanatory power of alternative models was compared using vuong’s non-nested model selection test. The results show that performance evaluation criteria based on theory of constraints have more explanatory power than other conventional indices in explaining non-performing loans rate. It is recommended to evaluate the performance of Iranian banks based on the rich concepts of Throughput Accounting.
