Forestry Logistics: The Challenges
Challenge #1: Merging Road Infrastructure •
Integrate Forest Road Network with Standard Street Datasets
•
Provide a Single, Continuous Network for Optimization
•
Match Road Pairs, “Conflation”
Challenge #2: Scheduling Restraints and Parameters •
Many Forestry-Specific Parameters: -
-
Capacity of Trucks Size of Timber Maximum Angles/Gradients Availability of Loading/Unloading Equipment Back-ups at Paper Mills
Challenge #3: Dynamic, Real-time Optimization •
Weather Changes -
Rain, Snow, Wind
•
Equipment Availability
•
Plant Congestion
•
Average Speed Changes
3-Step Solution
