Prospect of Budgetary of one Bank for Offer Entrance to Capital Market via Mathematical Model

Introduction: Today advantage of modeling in different science has abundantly used. In this paper budgetary manner of one imaginary bank during four years according of mathematical models was examined Aim: In this paper a prediction of a governmental bankʹs budget for four continuous years has been investigated by the use of a mathematical model. Materials and Methods: For this reason , the budget is simulated with an assumed element from a composite cylindrical structure , which its behavior is different in two opposite sides. Four external parameters such as inflation rate, governmental budgets, cash flow growth and GDP, as external forces which apply force to the assumed element and cause both spinning and pushing movements and at the end cause structure contraction . Five internal force such as incomes, costs, benefits and losses, sources and uses are simulated a orthotropic coefficient .Then the fore mentioned equations were solved with the PDE method with the boundary condition to make up to solution of the problem Results: The result of the external equations of the model was the sum of the spinning and pushing forces .The results from the model showed that the assumed force for the prediction of the assumed bankʹs budget was appropriate and where budgeting is linear, the error percentage of the model is small according to the bankʹs performance. Conclusion: The results showed that this model has minimum of residual in nonlinear area, also when budgetary was interred in nonlinear area; however amount of residual in this model was increased with theoretical results
