Locating a waste treatment facility by using stochastic

  1. 1. Locating a waste treatment facility by using stochastic multicriteria acceptabilityanalysis with ordinal criteria Group members: Mohd Farid Mohd Shafie S.Yasmin Grace Saiful Zaidi
  2. 2. 1. IntroductionSolid waste management company to build new solidwaste management area near Lappeenranta (SouthEastern), FinlandProblem : current landfills not able to satisfy recentrequirement on the waste treatmentNational waste plan requires recycling of municipalsolid waste from 50% - 70% by year 2005
  3. 3. New waste treatment area will be more centralizedwaste treatment , less environmental (moderntechnologies applied)Waste : households, agriculture and buildings sites.(Small amount hazardous pass through the plant)current landfill use traditional process it leads to uglyscenery, land value and property decrease and slowingthe development growth
  4. 4. Problem characterized as group MCDM problem :- no preference information was available- ordinal measurements for the criteria wereavailable.New waste treatment area :2-4 years : composting plant, facilities and landfills20 years : operating time of plant15 years : for the equipment100 years will remain in location but re planning mighttake place
  5. 5. 2. Legislation & Participation • Finnish legislation, more towards “direct and indirect” effects inside and outside of the territory1 of the Finnish project. • all citizens affected by the project , allowed to participate in the EIA procedure to express2 opinions (written) • Supervisory group (stakeholders) are formed to understand citizens opinion and public meetings3 were held.
  6. 6. 3. Problem & Alternativessix alternative , but only three of the alternativediscarded because:Close to the settlement areaToo valuable to the scenery and naturepublic meeting, they suggest four alternative forwaste treatment area (Herttuanvuori,Kukkuroinmaki, Laapmaki and Ryosola)
  7. 7. Citizens • Negative view towards the plant effects : to traffic, comfort , recreational use, effectpoint of economy, decrease value in real estate and nature. view Positive view new road improve the traffic connections The • Directly to the requirements of the legislationplanner’s • 10 points that effects that from the project opinion • 17 criteria, several criteria can not be measured including positive and negative effect which indirectlyCriteria ranking produced by the experts approved by supervisory
  8. 8. The ranking for the criteria basedon the benefit to the environment. 1– 2– 3– 4– Best Better good worse
  9. 9. 5. SMAA – O : Stochastic Multicriteria Acceptability with Ordinal CriteriaDeveloped for discrete multicriteriaproblems Based on exploring weight space in order to describe the valuation that would make each alternative the preferred one SMAA –O method is descriptive.
  10. 10. Formula
  11. 11. 6. Results of analysis
  12. 12. • There are alternative ways for performing the ordinal to cardinal scale mapping. – Use identical mappings from full range {1,……,4} [0,1], for each criterion or – Choose the smallest sufficient range for each criterion• For table 2 is the 1st approach- it shows that the best place Kukkuroinmaki and Herttuanvuori because they get high acceptability indicies (%).• For table 3 is the 2nd approach-the result shows that the acceptabilities of Kukkuroinmaki and Herttuanvuori change slightly, but they still remaind the only widely acceptable alternatives.
  13. 13. • These conclude that the result are not sensitive to how the mapping was done• After adding some constraints based on the data collected, the analysis was repeated.• After looking at the result, decision maker (DM), chose Kukkuroinmaki alternative as the forthcoming location of the plant.
  14. 14. 7. Discussion 1 The EIA process consider very good by the participants 2 Evaluation on the social effects was successful 34 alternatives analyzed in detail and elimination of 2 poor alternatives were done
