Explore a tree-search heuristic for stochastic production-distribution planning with transportation mode-dependent lead times in this 48-minute seminar from GERAD Research Center. Delve into the complex problem of simultaneous production and transportation decisions, including selecting optimal transportation modes for shipping goods to customers. Learn about the trade-offs between shorter lead times, higher costs, and increased flexibility in reacting to demand changes. Examine the multi-stage problem with a discrete finite time horizon and stochastic customer demand, solved using a rolling horizon framework and static-dynamic problem representation. Discover the tree-search heuristic based on Anytime Column Search and Limited Discrepancy Search, featuring a node selection strategy that aggregates scenarios for efficient solution improvement. Gain insights into decomposition of time periods, dynamic programming, branch and cut techniques, flow-based guiding heuristics, and the impact of scenario trees on stochastic solutions.
