THE VEHICLE ROUTING PROBLEM (VRP) IS CENTRAL TO LAST-MILE LOGISTICS, YET A GAP REMAINS WHEN PRODUCTS HAVE LATE RELEASE TIMES AND VEHICLES CAN BE RELOADED EN ROUTE VIA MOBILE SATELLITES THAT RENDEZVOUS WITH RELOADING VEHICLES AT CUSTOMER LOCATIONS. WE PROPOSE THE VRP WITH RELEASE TIMES AND RELOADING AT MOBILE SATELLITES (VRP-RT-RMS) AND DEVELOP TWO MIXED-INTEGER LINEAR PROGRAMMING FORMULATIONS: A THREE-INDEX (MILP-3) AND A TWO-INDEX (MILP-2). THE OBJECTIVE MINIMIZES TOTAL DISTANCE SUBJECT TO CAPACITY, ROUTE DURATION, SYNCHRONIZATION, AND TIME CONSTRAINTS. WE GENERATED 40 INSTANCES FROM REAL DATA (10 PER SIZE N E{10,15,20,25}). EN-ROUTE RELOADS SIMULTANEOUSLY REDUCE DISTANCE AND FLEET SIZE AND CAN RESTORE FEASIBILITY WHEN THE CLASSICAL VRP IS INFEASIBLE. TO CONTRAST THE CLASSICAL VRP WITH OUR VRP-RT-RMS, WE ANALYZED A PARTICULAR INSTANCE WITH N =10 CUSTOMERS: TOTAL DISTANCE DECREASED BY 7.26% AND THE NUMBER OF VEHICLES FELL FROM 5 TO 3. AS INSTANCE SIZE GROWS, MILP-2 SHOWS SUPERIOR SCALABILITY AND EFFICIENCY COMPARED WITH MILP-3. BEYOND THE TECHNICAL SCOPE, COORDINATING RELOADS IS PERTINENT TO URBAN OPERATIONS WITH LATE PRODUCT RELEASES, LOWERING KILOMETERS TRAVELED AND DELIVERY TIMES.

SUSTAINABILITY HAS BECOME A KEY ISSUE IN THE FOREST INDUSTRY; THIS RESEARCH AIMS TO ANALYZE THE QUANTITATIVE TECHNIQUES AND METRICS APPLIED TO THE FOREST-TO-LUMBER SUPPLY CHAIN TO ACHIEVE SUSTAINABLE DECISION-MAKING DURING THE LAST SIX YEARS. THE METHODOLOGY USED WAS THE PRISMA SYSTEMATIC LITERATURE REVIEW GUIDE, WHICH PROVIDES A COMPLETE AND UPDATED VIEW OF THE SITUATION. A TOTAL OF 724 PUBLICATIONS WERE COLLECTED FROM THE WEB OF SCIENCE DATABASE. CONSEQUENTLY, 85 PAPERS WERE SELECTED FOR ANALYSIS AND SYNTHESIS AFTER APPLYING INCLUSION CRITERIA. THE RESULTS SHOW A GROWING INTEREST IN SUSTAINABILITY IN THE FOREST-TO-LUMBER SUPPLY CHAIN, WITH A PEAK OF PUBLICATIONS IN 2019. MATHEMATICAL PROGRAMMING AND SIMULATION MODELS ARE ON TOP OF THE QUANTITATIVE TECHNIQUES APPLIED. THESE TECHNIQUES ARE APPLIED TO THE SUPPLY CHAIN COMPONENTS, CLASSIFIED ACCORDING TO THE RAW MATERIAL?S DEGREE OF PROCESSING OR TRANSFORMATION LEVEL IN FOREST ENTITIES, SAWMILLS, TRANSPORTATION, AND OTHER ENTITIES. THE CONCLUDING REMARKS HIGHLIGHTED THAT 19 PUBLISHED WORKS RESEARCH THE SOCIAL DIMENSION, 43 EXPLORE THE ENVIRONMENTAL DIMENSION, AND 55 EXAMINE THE ECONOMIC DIMENSION. MOREOVER, IN THE ENVIRONMENTAL DIMENSION, THERE IS A CONCENTRATION ON THE USE OF METRICS ASSOCIATED WITH GREENHOUSE GASES, AND TO A LESSER EXTENT, THEY HAVE BEEN CONCERNED WITH SOIL AND WATER. ADDITIONALLY, IN THE SOCIAL DIMENSION, THEY HAVE CONCENTRATED MAINLY ON THE WORKERS, LEAVING THE LOCAL COMMUNITIES AROUND THE SUPPLY CHAIN IN THE SECOND PLACE. OUR SYSTEMATIC REVIEW REPORTS THE TECHNIQUES OR QUANTITATIVE METHODOLOGIES APPLIED IN THE FOREST-TO-LUMBER SUPPLY CHAIN AND THE METRICS USED TO HANDLE THE DIMENSIONS OF SUSTAINABILITY.
