Nowadays, the rapid growth of data in organizations has caused managers to look for a way to analyze them. Extracting useful knowledge from aggregation data can lead to appropriate strategic decision-making for the organization. This paper suggests an application of hybrid network based on amount month demand in every ATM device based on transaction mean of 9 months for 1377 devices to obtain customer behavior patterns, to do so, first designed a basic model based on an auto-regressive with exogenous input network (NARX) then, the optimization of the weight and bias of the designed network is made by the genetic algorithm (GA). As a result, finding the weights of the network represents a nonlinear optimization problem that is solved by the genetic algorithm. Paper results show that the NARX-ANFIS Hybrid network using GA for the learning of rules and to optimize the network weights and weights of the network and the fixed threshold can improve the accuracy of the prediction model. Also, classic models are more efficient and increased benefits and lower financing costs and more rational inventory cash control. As well, the designed model can lead to increase benefits and decrease costs in the bank so that, exact forecast and optimal cash upload in ATMs will lead to increase funds on the bank and rise customers and popularity the brand of the bank.

The purpose of this study is to develop proposals and recommendations for the implementation of a process model for the development of leadership qualities of public servants and justification of the conditions for ensuring its effectiveness in terms of digital transformation. The relevance of this study is due to the need to ensure development of the process of professionalization of the senior civil service personnel on the basis of development of leadership qualities that will contribute to the effective operation of the civil service of Ukraine, change management and successful implementation of reforms in Ukraine, taking into account the best world practices. The methodology for assessing the level of managerial competencies of public servants according to the degree of implementation of strategic (key) competencies has been developed.

The purpose of this work is to use structural analysis to create believable scenarios of Iranian food tourism. In the present study, to formulate plausible scenarios, first by reviewing the literature and interviewing experts, 37 factors affecting food tourism were extracted. The variables affecting the future of food tourism, directly and indirectly, were calculated using a questionnaire and analysis by MICMAC software. Finally, considering the two most critical factors called food festivals and sanctions/international relations, plausible scenarios for the future of Iranian food tourism were developed. Based on the results, four scenarios are presented. These scenarios include Golden Scenario, Limited Scenario, Neglected Scenario and Chaotic Scenario. In Golden scenario, which depicts the ideal conditions, as many suitable food festivals as possible are being held in a country, and sanctions are not imposed. According to Limited Scenario, holding more and better food festivals is on the officials’ agenda, but on the other hand, the country is under sanctions and pressure. In Neglected Scenario, holding festivals is the same as in the past, and the country is not sanctioned. In Chaotic Scenario, depicting the worst-case scenario, the festival process is the same as in the past and has not been developed quantitatively and qualitatively. Also, the country is in a problematic situation of sanctions. Creating Credible The industry's major players and beneficiaries greatly benefit from Iranian food tourism scenarios, which enable them to provide flexible preparation-based programmers in response to shifting circumstances. The techniques and factors that influence the growth of the business will be known to the participants and recipients of food tourism, and this will open up a multitude of opportunities for the players involved.

مدیران با ثبات این توانایی را دارند که جریان های نقدی مازاد درون شرکت را به سمت فرصت های سرمایه گذاری مؤثر و سودآور هدایت کنند. هدف اصلی این تحقیق بررسی رابطه بین ثبات هیئت مدیره، کارایی سرمایه گذاری و دارایی های نقدی مازاد است. طرح/روش/روش شناسی: جامعه آماری این پژوهش شرکت های فعال در بورس اوراق بهادار تهران با گزینش سیستماتیک 140 شرکت در بازه زمانی 1394 تا 1401 می باشد. این تحقیق از نظر هدف کاربردی و با استفاده از رگرسیون خطی چندگانه می باشد. بر اساس داده های تابلویی برای آزمون فرضیه ها. یافته ها: یافته های تحقیق حاکی از وجود رابطه مثبت و معنادار بین ثبات هیئت مدیره و کارایی سرمایه گذاری است. به عبارت دیگر، شرکت هایی با اعضای هیئت مدیره پایدارتر، کارایی سرمایه گذاری بالاتری دارند. همچنین، نتایج نشان می دهد که بین ثبات هیئت مدیره و وجه نقد مازاد رابطه معنادار و منفی وجود دارد. شرکت هایی که ثبات هیئت مدیره بالاتری دارند، میزان نقدینگی مازاد کمتری دارند. این یافته ها نشان می دهد که ثبات هیئت مدیره نقش مهمی در کارایی سرمایه گذاری و مدیریت نقدینگی در شرکت ها ایفا می کند.
