Abstract
The usual procedure when employing a T2 control chart for multivariate process monitoring is to take samples of fixed size n0 every h0 hours from the process. Recent studies have shown that using variable parameters (VP) schemes results in charts with more statistical power when detecting small to moderate shifts in the process mean vector. In this paper, the VPT2 control chart for monitoring the process mean vector is economically designed. The cost model proposed by Lorenzen and Vance is used here and is minimized through a genetic algorithm (GA) approach.

Abstract
Planning can be defined as a set of coordinated, coherent, and feasible activities to achieve specific and predetermined goals over a given time frame and based on available facilities. Implementation of economic development planning models is very important, according to prevailing conditions in society and the constraints in society. One of the models used in economic development planning is the mathematical planning model. In this article, we use a mathematical programming optimization model and we run it for real Iranian data over the period 2008-2012. Value added is defined by the Cobb-Douglas model, and the results of the model report labor force share, capital share and total factor productivity of the factors of production. According to the model results, if the Iranian economy could achieve higher value added, then Iran's economic growth in 2012 would have changed from -6.6% to 3.1%. Based on the results, the efficiency score of each section has calculated and we rank the sections based on their efficiency score.

Abstract
Evaluating the performance of countries in international markets and measuring how they use allocated resources provides a clear picture of the state of trade management in countries. If there is information about the performance of export markets, you can make clear business rules, allocate quotas and loans by international organizations such as the World Bank and its subsidiaries, financial and non-financial support, allocate credit and establish financial and non-financial transactions with a clear vision. The main purpose of this paper is to better understand and accurately assess the current state of research in the field of evaluating the performance of countries' export markets and identifying the indicators and variables used in this regard. In this research, the systematic literature review (SLR) method has been used to collect and review previous studies. By integrating automatic and manual search strategies, all related research articles published in this field in the period from 2009 to 2019 in Persian and 2008 up to 2018 in English are covered. The results show that countries' performance evaluations are mainly based on economic indicators and focus on gross domestic product standards that focus more on the economic dimensions of performance. Because these criteria are not able to explain the non-economic dimensions of functional performance of countries, researchers have evaluated non-economic criteria such as level of education, human capital, environmental indicators, and so on. Finally, it is suggested that economic and non-economic criteria be evaluated simultaneously to evaluate the performance of countries’ export markets.
