Thus, Ali and Seiford in 1993 suggesting a bound for claimed that it would prevent unfeasibility/infinity of multiplier forms/envelope of DEA problems. Mehrabian in 2000 rejected the validity of the boundary and offered another boundary for in CCR and BCC Models of DEA and further, determined assurance value under special terms. Assigning value in network structures may cause encountering unfeasibility/infinity of multiplier forms/envelope challenge. Therefore, the purpose of this study is to determine boundary in network structure and to define assurance value. ER -
