In this presentation, some basic concepts about aggregation operators are given. Also, several important families of aggregation operators such as weighted arithmetic means, ordered weighted averaging (OWA), t-norms, t-conorms, uninorms, nullnorms and so on and their properties are introduced. Generally, choosing an aggregation operator is not arbitrary and some issues such as simplicity, numerical efficiency, easiness of interpretation and sensitivity should be taking into account. So, here, by giving some criteria, aggregation operators are compared which is helpful to choose the proper one in application.
