Simultaneously, the properties and the special cases of these operators are discussed.

In the age of the knowledge-based economy and the rapid development of information technology, enterprise management is facing great challenges and has entered an era of prudent management. Although some good information may be available, it is not enough to answer all questions about the outcomes. /SMask /None In this situation it is very common to use. We introduce a new aggregation operator called the linguistic ordered weighted averaging distance (LOWAD) operator. We review recent advances in the field of decision making under uncer-tainty or ambiguity. Therefore, we can construct a lot of other decision-making approaches as it, has been constructed in the previous tables. Therefore, it is straightforward to extend these models in a probabilistic framework.

The developed method adopts the new operational rules with the accurate operations, and it can overcome some existing weaknesses and capture the interrelationship among the multi-input PLTSs, which easily express the qualitative information given by the decision-makers’ cognition. We study its definition and some of its main properties. these methods as particular cases of a more general framework.

In the following, we are going to develop a multi-person decision-making process with, vides a more complete representation of the problem because it is based on the opinion, of several people. Thus, we can formulate the following decision-making approaches: Moreover, we can also extend all the previous decision-making approaches presented, Note that there are a lot of other methods and techniques that deal with decision-making, problems.
