  This paper deals with inverse problems subject to imprecise or vague
information of some involved data by means of interval-valued functions. To
provide interval solutions to the inverse problems we have adopted a perturbed
collage-based approach and we have also introduced a numerical procedure by
means of the use of interval bases in a sense. To illustrate the results, and
as an application, we have studied the Volterra interval-valued integral
equation, and provide some computational examples.
