Abstract

Dempster‐Shafer evidence theory is a very useful tool in dealing with the decision‐making of uncertain information. However, the classical evidence theory is no longer applicable when the frame of discernment (FOD) is incomplete. Moreover, incomplete FOD is an important reason for the emergence of conflict. So it is necessary to identify whether the FOD of the system is complete or not. In this paper, a method is proposed to identify the incomplete FOD under framework of the generalized evidence theory dealing with incomplete information. Within the proposed method, pieces of evidence are generated from the attributes of each sample firstly; then three criteria are used to identify weather the FOD is incomplete according to these evidence. The main parameters of the criteria are the amount of ∅ being a focal element in generated evidence, the mass of ∅ in the weighted average evidence from generated evidence, and the mass of ∅ in the combination of generated evidence. Some experiments are used to demonstrate the effectiveness of the proposed method.

  • Dempster-Shafer evidence theory (D-S evidence theory) [1, 2] is widely used in many fields such as decision-making [3,4,5,6], evidential reasoning [7, 8], uncertainty measure [9, 10], and others [11,12,13,14,15] because of its advantages in handling uncertainty information

  • How can we identify the completeness of frame of discernment (FOD) Θ according to T? In this paper, for the sample T, at first q generalized basic probability assignment (GBPA) which allow the empty set to have mass (i.e., m(0) > 0), denoted as m1, m2, . . . , mq, will be generated from the q attributes
