We investigate the effects of the randomness and electron-electron interactions onthe competition between superconductivity and charge density wave in one-dimensional bipolaron system in the half-filled case at finite temperatures. The model istransformed into the S= 172 XXZ-chain with random fields, and we carry out thenumerical simulation using the transfer matrix by Suzuki-Trotter formula. When theinteraction between neighboring bipolarons is attractive, the suppression of the cor-relation functions is described by the scaling law. This result is discussed in connection with the Fukuyama-Lee length including the quantum fluctuations. When the in-teraction is repulsive, weak randomness suppresses the charge density wave andenhances the superconductivity, but strong randomness suppresses both.
