Due to the importance of public transportation, which has become today an important urban problem with special conditions, this study was conducted aimed at determining the parameters affecting the mathematical programming model of the appropriate transportation system. The study was performed by modeling method, and the problem was solved in three different sizes (small, medium and large) to show the efficiency of the model and the proposed solution methods. Some common test problems in the literature were selected and the required characteristics of the problem under study were defined for them as needed, since there are no sample test problems in the literature to examine the performance of the developed algorithms. The results indicated that some of the most important parameters affecting the designed mathematical model were movement risks, fatigue and drowsiness while driving, demands at the source node, demands at the destination node, number of vehicles across the network, the time interval between requests, and the time interval between two consecutive requests. The mentioned parameters were so effective that little changes in parameters such as demands at the source node, demands at the destination node, and the number of vehicles across the network significantly increased time and decreased profitability. the company has a significant effect on the debt cost rate and capital cost rate and does not have a significant effect on stock prices. Finally, the share price shows little sensitivity to the company's financial structure.

The core goal of this study was to simulate the share and predict the current and non-current receivables in Shahr Bank using an agent-based approach. To this end, we employed the data related to the examined features in 11 bank branches aimed at determining the degree of importance of each of the factors affecting the repayment behavior of borrowers using the C5.0 algorithm, the decision tree method, and the simulation process in NetLogo software. We utilized the comparison of the repayment status of a sample of 100 customers over the past year (12 months ago) and at present aimed at assessing the simulated model. The estimation results of the simulation model, as well as the real findings, suggested that the number of type 1 customers (with active repayment status) has decreased during the last 12 months and the number of type 2 customers (with past due repayment status) has enhanced. If the economic recession conditions continue the same way, and considering the low effect of the recession conditions on the businesses of the bank''s customers in the next four years, then, the ratio of the bank''s current customers will decrease from about 89% to about 81%, while the ratio of the past-due customers of the bank will increase to more than double to about 13%. In the next step, we tried to simulate the future situation of the ratio and the share of the current bank customers'' claims in the next 4 years.

Religious tourism is a kind of tourism that nowadays is defined by the elements of the spiritual motivation of the tourists rather than the destination of this tourism. This paper aims to introduce The Eye of Insight Islamic mysticism and Third Eye in the philosophy of the East and to investigate the importance of opening these eyes in creating the sense of spirituality for the tourists. Results showed that both in Islamic mysticism and in the philosophy of the East, human perfection has been depicted as a journey from material world to the world of meaning. In this regard, seekers are recommended to open eyes of their hearts in order to contemplate on nature and explore the meaning hidden in it. Relying on such an approach helps the tourists correct their attitudes toward nature based on this ideology and is effective in the individual and ethical perfection of the tourists. It has also abundant effects in collective and global scale since it can prevent the negative effects of the view that considers nature as a means for enjoyment and consumption which is frequently seen in mass tourism. This approach is also useful in sustainable tourism and protection of natural resources.
