The electrical resistivity of the heavy-fer mion alloy system is calculated through the Yoshimori-Kasai model with the application of the slave-boson technique. The residual resistivity of the system is found in the mean-field approximation by using the CPA method-The low-temperature resistivity maximum in the concentrated alloy is aslo obtained as the Gaussian fluctuation of the slave-boson field is included.
