In the original published article the “Conclusion and future scope” paragraph has been incorrectly published.

The correct paragraph is as below.

2 6 Conclusion and future scope

In view of the past research done in the field of assignment problem, the basic aim of this article is to formulate a bi-objective fractional assignment problem under uncertainty. In case of conflicting objective functions, it is not necessary that the optimal solution of one objective also satisfies the other objective functions, so in such situations it is better to adopt a compromise way. Therefore, to obtain the compromise optimal solution that satisfies both the objectives, minimizing time and maximizing efficiency, a fuzzy programming technique has been used with linear membership function and quadratic membership function. The solutions at different values of α are summarized in Tables 3 and 4 and are shown graphically as well. In future research the efficiency of suggested models can be checked by applying them in real life problems and also, the utility of the formulated problem can be checked by some recent or new methods.
