Relaxation and decoherence properties of the exactly solvable Coleman-Hepp model are studied by determining the time evolution of the entropy. With the aid of our previous results, we can calculate the entropy by solving an eigenvalue problem for the reduced density matrices. Detailed numerical studies are performed to clarify the decoherence processes.
