An experiment with plant layout formulated as a quadratic assignment problem gave the following results: (1) The CRAFT algorithm does as well as human subjects in solving the plant layout problem; (2) CRAFT does better as problem size increases if the human subjects have no prior knowledge of...

In this article, the authors develop three dynamic models of urban growth with a focus on the efficient utilization of lumpy urban infrastructure. First, the authors show that the optimal growth rate depends on the rate at which infrastructure capacity is consumed when public service levels are...

Public-sector planning problems are typically complex, and some important planning issues cannot be captured within a mathematical programming model of a problem; such issues may be qualitative in nature, unknown, or unrevealed by decisionmakers. Furthermore, there are often numerous solutions...
