Facility Location Under Zone Pricing
研究了企业在区域定价策略下，如何同时确定最优的设施位置、价格、定价区域和市场范围以最大化利润，并提出了一种结合投影法和分支定界的求解算法。
Zone pricing consists in determining simultaneously several delivered prices together with the zones where these prices apply. A model and algorithm are proposed to determine optimal facility locations, prices, tariff‐zones, and market areas in order to maximize the firm's profit under zone pricing. The resulting nonlinear mixed‐integer program is tackled by projecting the objective function on the price space, solving repeatedly uncapacitated facility location problems for fixed values of the prices. The implicit profit function so defined is optimized by branch‐and‐bound. Computational results are reported.
