in this research, an innovative numerical simulating approach for time domain analysis of multi degrees of freedom structures with uncertainty in dynamic properties is presented. a full scale finite element model of multi-story and multi bays of three sample structures has been constructed. the reduced order model of structure with holding the dominant and effective gramians in the balanced sta...

The paper analyzes the sensitivity of two unit system for parameters uses Regenerative Point Graphical Technique (RPGT). Taking failure and repair rates constant. A state diagram depicting transition is drawn. Expressions path probabilities mean sojourn times, time to failure, availability system, busy period server, expected number server’s visits are derived using RPGT. Sensitive analysis don...

Decision making plays an important role in economics, psychology, philosophy, mathematics, statistics and many other fields. In each field, decision making consists of identifying the values, uncertainties and other issues that define the decision. In any field, the nature of the decisions is affected by environmental characteristics. In this paper, we are considered the production planning pro...
