One of the interesting parts in the study of uncertainty is to learn about their fusion models. In particular, while studying about fuzzy set and rough set, one may be interested to know about their joint models. Rough fuzzy sets and fuzzy rough sets are those types. After the introduction of soft sets, many research developments started emerging both in the theoretical and application prospective manner. Though this theory sounds good, it has its own limitation in describing expert opinion. To overcome this difficulty the novel idea of soft expert set was being developed. This paper attempts to inter-relate soft expert set with rough fuzzy set in theoretical aspect. An approach to decision-making situation based on the soft expert rough fuzzy set model is also given in a lucid manner.
