In the open world,a frame of discernment may not contain all possible descriptions of the proposition. Traditional PCR combination rules can not fuse the information under the frame of discernment is incomplete. To solve this problem,this paper presented generalized PCR combination rules( GPCRs) based on the basic framework of the generalized evidence theory. GPCRs extended the applicable scope of the traditional PCR combination rules. Under the case that the frame of discernment is incomplete,GPCRs are able to fuse the information effectively. Moreover,GPCRs can obtain better fusion results than the generalized DST when there are larger conflicts between evidence sources. Some numerical examples are used to show the efficiency and reasonable of the proposed GPCRs.
