In this paper, a model is developed for the optimization of distributed database systems and computer networks.Comparing with previous work in this area, the model is more complete since it considers simultaneously tlie distribution of computation power, the allocation of programs and databases, and the assignment of communication lines.In addition, we have developed a "bounded braiich and bound" algorithm for the model.The algorithm is more efficient than most of the existing general nonlinear integer programming algorithms and can avoid the disadvantages of heuristic algoritlims which were used widely in the optimization of computer networks. The algorithm has been implemented in FORTRAiM.There is no assumption on a prefixed network topology.The optimization procedure searches for a system configuration satisfying various constraints.The model developed in the paper can be used in the design of distributed databases and computer networks.It can also be used to help managers to decide whether to centralize or decentralize their information systems. 073^350. it
