constraint theory

Through the grid matrix model, stock of companies can be classified according to different characteristics in a matrix then formed portfolios. In this research, using the data of 156 companies listed in Tehran Stock Exchange during the period of 2011-2017 and through the grid matrix model based on throughput accounting’ criteria as the proposed model, the formed portfolios and their performance with the traditional grid matrix model and market portfolio were compared. The results of the research show that the proposed model portfolios have a higher performance than the traditional grid matrix model based on Sharp, Sortino, upside potential and Omega criteria, and the portfolios of companies with high system performance, in addition to the above criteria, also had higher performance than traditional grid matrix model based Jensen's criteria. Also, the performance of these portfolios in terms of upside potential and omega criteria is higher than market portfolio, and the performance of companies with low system performance has a stronger correlation with market portfolios

a traditional set of relevant functional and functional indicators makes managers attend several areas rather than focusing on limited resources . therefore , they should be avoided . the correct use of the system based on limiting factors requires the use of a full set of supporting performance measures and reporting systems . The key concept behind this new system is to use a measure or report that is solely and fully focused on the performance of the company 's generative system , which is realized with the criterion of the optimal performance - based optimal performance based on limited resources . in this paper , we examine the explanatory power of accounting accounting for performance measurement , relative to traditional criteria in cement industry firms in tehran stock exchange in the years 1397 and 1398 . the results of testing hypotheses show the existence of meaningful difference of criteria for measuring the performance of selected firms relative to traditional criteria .

Theory of Constraint(s) is one of the decision-making techniques in strategic management accounting and one of the new theories of performance appraisal that thinks about the growth strategy with a systematic approach to the firm and in line with the cost management strategy. The use of Theory of Constraint(s) concepts in the banking industry is a novel topic and therefore explaining the capital adequacy ratio through the accounting model of system performance, can lead to systemic thinking in banks. In this study, the key variables of 17 banks in the period 1397-1387 were calculated based on the common (traditional) approach and also the theory of constraints approach. Statistical models were also tested using 11EViews software. The research findings indicate that the banking system can use the rich concepts of constraint theory in the performance appraisal process as well as its operational and strategic decisions and use it to improve the capital adequacy ratio.
