Acceptance control charts (ACC), as an effective tool for monitoring highly capable processes, establish control limits based on specification limits when the fluctuation of the process mean is permitted or inevitable. For designing these charts by minimizing economic costs subject to statistical constraints, an economic-statistical model is developed in this paper. However, the parameters of s...

The article is devoted consideration of the processes ecologization urbanized territories. author notes that urbanization has caused many environmental problems, among which vulnerability urban systems and low level quality can be noted. In modern Russian Federation, 75% total population country lives in areas. features development territories, leading to pollution further degradation, are high...

CCC-r control chart is a monitoring technique for high yield processes. It is based on the analysis of the number of inspected items until observing a specific number of defective items.  One of the assumptions in implementing CCC-r chart that has a significant effect on the design of the control chart is that the inspection is perfect. However, in reality, due to the multiple reasons, the...

Economic and financial processes are complex and highly nonlinear. However, somewhat surprisingly, linear models like ARMAXGARCH often describe these processes reasonably well. In this paper, we provide a possible explanation for the empirical success of these models. 1 Formulation of the Problem Economic and financial processes are very complex. It is well know that economic and financial proc...

economic recession is considered as a repeatable and constant phenomenon in capitalist economy. countries which experienced rapid economic growth have inevitably applied a balancing program after that. generally, whenever industrial, financial and commercial developments occurred in a rapid growth, the reverse and changing processes would appear. consequently, they will affect the financial and...
