分布式计算机系统的设计是一项复杂的任务，需要解决几个难题。计算资源和数据库在广域网上的定位就是其中一个尚未得到很好解决的问题。这一问题的解决方案涉及确定计算机设施的数量和大小及其位置、配置数据库并在计算机设施之间分配这些数据库。给出了该问题的整数规划公式。开发了启发式和最优解程序，并报告了这些程序的计算经验。讨论了该模型对设计分布式系统的意义。
Design of distributed computer systems is a complex task requiring solutions for several difficult problems. Location of computing resources and databases in a wide-area network is one of these problems which has not yet been solved satisfactorily. Solution of this problem involves determining number and size of computer facilities and their locations, configuring databases and allocating these databases among computer facilities. An integer programming formulation of the problem is presented. Heuristic and optimal solution procedures are developed and computational experience with these procedures is reported. Implications of the model for designing distributed systems are discussed.
