Grey minimax regret assessment of the MSW regionalization for the lower Rio Grande Valley, Texas

Solid waste management (SWM) is at the forefront of environmental concerns in the South Texas area of the Lower Rio Grande Valley. Dwindling landfill space drives area decision makers to look for innovative and forward-looking solutions to address the landfill space shortage. Presented are the results of a regional solid waste characterization study together with an innovative minimax regret grey integer programming algorithm to outline an optimal regional coordination of solid waste routing and possible landfill/incinerator construction. The results hope to give decision makers well-hedged sets of options that consider various forms of system and event-based uncertainty that can lead to more efficient waste routing and facility planning for the time frame of 2005 to 2010.
