Abstract:

This paper addresses a multiple objective optimization model to determine the file allocation and query routing assignment in a distributed information system. The problem is formulated as a zero-one integer nonlinear programming problem with multiple objectives. The optimization problem under consideration is shown to be NP-hard. The authors adopt an iterative improvement procedure, which gives the Pareto Optimal solution. They further illustrate the present methodology with a small sample system.
