  Determining the leanness of different organizations is one of the key factors of progress into establishing a system without wastes and maximizing productivity in whole supply chain management. Lean manufacturing as a management philosophy concentrates on eradicating wastes in the whole value chain of a product. Using the improved dimensional analysis and its conversion to the standard form, this paper aims at identifying and analyzing 6 main factors and 35 sub-factors. Also, we used multi-criteria decision-making techniques according to the direct role of experts and differentiation of their votes to the specified alternatives. Analytic hierarchical process and Fuzzy-Topsis were used to define the linguistic weights of experts in our model. Additionally, linguistic values were parameterized by triangular fuzzy numbers to optimizing the decision making methods and avoid vagueness. The results show that the degree of adaptability of Rose Fire Place Company with lean manufacturing factors and characteristics is 0.52. Also, the results indicate the distance of various parts of the production management with respect to lean manufacturing. Finally, this approach is recommended for being used in every assembly industries.   Manuscript profile

  In this paper, river regime equations through developing of unit stream power equation and based on data of babolrood River were derived. For this purpose, with the review of previous research, the principles and concepts of regime and hydraulic geometry of the river is mentioned. then, methods and out-comes of former researchers are classified. On the next step, based on dimensional analysis, unit stream power as a function of river flow parameters including suspended sediment load and specific gravity of particles is developed. Using the unit stream power equation and babolrood River' data, regime equations are derived for these rivers. Finally, the results derived from regime equations are compared with the field data and regime equations of the other researchers. A good agreement was observed between field data and values resulted from developed regime equations in this research. Manuscript profile

  The study of the economic system at the international level shows the fact that there is always a close relationship between investment and the level of economic development of countries. This means that countries with an efficient model in allocating capital to different economic sectors, often have higher economic development and consequently social welfare. This is a study of commercial banks. This study was conducted to investigate the effect of business unit life (company age) in a multidimensional analysis method to predict the credit risk of legal customers (studied by commercial banks) and the analysis was reviewed and the desired results were presented. .In general, according to the useful results obtained from the statistical test, which indicates 85% accuracy of the multidimensional analysis model of preferences in mode A and indicates the absence of errors on average in mode B.Therefore, it can be concluded that examining the lifespan of a business unit can increase the accuracy of the above model.
