TY - JOUR TI - Uncertain fractional operator with application arising in the steady heat flow AU - Salahshour S AU - Ahmadian A AU - Ali-Akbari M AU - Senu N AU - Baleanu Dumitru JN - Thermal Science PY - 2019 VL - 23 IS - 2 SP - 1289 EP - 1296 PT - Article AB - In the recent years much efforts were made to propose simple and well-behaved fractional operators to inherit the classical properties from the first order derivative and overcome the singularity problem of the kernel appearing for the existing fractional derivatives. Therefore, we propose in this research an interesting approach to acquire the interval solution of fractional interval differential equations (FIDEs) under a new fractional operator, that does not have the above defect with uncertain parameters. In fact, this scheme is developed to achieve the interval solution of the uncertain steady heat flow based on the FIDEs. An example is experienced to illustrate our approach and validate it.
