AB  - The role of ɛ value in Data Envelopment Analysis (DEA) is obvious for DEA researchers and
improperly determining this value leads to unfeasibility/infinity of multiplier form/envelop in DEA problems.
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.
