##### 1. An algorithm for determining common weights by concept of membership function

S. Saati; N. Nayebi

Volume 04, Issue 03 , Summer 2015, Pages 165-172

##### Abstract
Data envelopment analysis (DEA) is a method to evaluate the relative efficiency of decision making units (DMUs). In this method, the issue has always been to determine a set of weights for each DMU which often caused many problems. Since the DEA models also have the multi-objective linear programming ...  Read More

##### 2. Application of triangular functions for solving the vasicek model

Volume 04, Issue 03 , Summer 2015, Pages 173-182

##### Abstract
This paper introduces a numerical method for solving the vasicek model by using a stochastic operational matrix based on the triangular functions (TFs) in combination with the collocation method. The method is stated by using conversion the vasicek model to a stochastic nonlinear system of $2m+2$ equations ...  Read More
