  1. OPTIMIZING THE SOLID WASTE COLLECTION SYSTEM OF ACSS USING LINEAR PROGRAMMING & GIS Mohammed Abdi Ali Term Project Fall 2000 CE 394 GIS for Water Resources For additional information, visit http://www.ce.utexas.edu/stu/alima/home.html/swgis.htm

  2. Topics of the Presentation: • Introduction • ACSS • Model formulation for Solid Waste Collection Optimization • Use of GIS in solid waste management • Objective of Term Project • Data Acquisition & Preparation • Analysis Using Arc View GIS Spatial Analyst • Analysis Using Arc View GIS Network Analyst • Conclusion • Acknowledgment

  3. 1. Introduction • ACSS • ½ of the City’s population solid waste service provider • Provides service for commercial & residential customer for both recyclable and disposable solid wastes. • Provides both stationary container and hauled container services • Offloading sites :TDS, BFI, MRF,Hornsby Bend, & COA Landfill • Model of the optimization: • Input Data: • Source location • Transportation street networks • Transportation route length between pick-up locations • Waste generation data at pickup location • Location of offloading sites • Analysis (optimization): • Use linear modeling • Minimize collection cost by considering the collection distance( route) and collection time • Constraints: regulation, traffic loads, and working hours, truck capacity, and other conditions. Types of collection system • Output: • Optimum collection route • Collection time • Minimum cost

  4. Use of GIS in solid waste management 2. Objective of the Term Project: • Investigating the existing capacity of Arc View GIS tools for optimizing city’s solid waste collection system • To use the existing Arc View tools for preliminary route optimization 3. Computer Data Acquisition & preparation • Customer locations • Austin City Street network • Offloading and Office locations • Identifying Commercial, residential and recyclable customers and hauled container collection system services

  5. Commercial Customer, Offloading & Office locations

  6. 4. Analysis Using Arc View Spatial Analyst • The proximity analysis tools Procedures:

  7. Proximity to disposal sites – sample proximity analysis

  8. 5. Analysis Using Arc View GIS Network AnalystThe Closest facility to Hauled Container Collection System-Procedures:

  9. Out put of the Analysis

  10. Sample Best Route AnalysisProcedures:

  11. Out of the Analysis

  12. 6. Conclusion • The existing Spatial and Network analyst tools have limited application in City’s solid waste collection system optimization • The existing tools are suitable for hauled container collection system than the stationary container system • Improved tools or integration of additional linear models to include all the factors that may affect the collection system is necessary • The existing tools may be helpful for locating transfer stations and landfill sites for new collection system • Acknowledgment -City of Austin Solid Waste Service Office
