Sas en – a swarm of agents for a sustainble environnent

  1. 1. Ruvindee Rupasinghe, Sanjaya Ratnayake, Anuruddha Ranatunga, Amila Sajayahan, Asoka S. Karunananda Faculty of Information Technology University of Moratuwa SAS_EN – A swarm of Agents for a sustainble Environnent
  2. 2. Overview <ul><li>Introduction </li></ul><ul><li>Problem Definition </li></ul><ul><li>Existing Solutions & Others’ work </li></ul><ul><li>Aims and Objectives </li></ul><ul><li>Using MAS for environment sustainability </li></ul><ul><li>Analysis and Design </li></ul><ul><li>Implementation </li></ul><ul><li>Discussion & Further work </li></ul>
  3. 3. Natural Environment <ul><li>Natural environment has been the infrastructure for all activities of living beings in the world. </li></ul><ul><li>All living beings occupy and consume environmental resources while releasing the waste products to the same environment </li></ul><ul><li>Undoubtedly, environment is the most precise resource to be effetely utilized and managed. </li></ul>
  4. 4. Nevertheless <ul><li>When compare with other living beings, humans release harmful waste products to the environment as a part of their consumption of environmental resources </li></ul><ul><li>Environment space has been utilized by the man kind by destroying the natural balance </li></ul><ul><li>Humans consume limited environment resources without allowing regeneration of such resources </li></ul>
  5. 5. Exsisting approches …. <ul><li>Environmental information systems </li></ul><ul><li>Grow rooms </li></ul><ul><li>Grow boxes </li></ul><ul><li>Automation Components </li></ul><ul><li>However, all of them follow a reactive paradigm, where the system waits till the environment change for making any action. </li></ul>
  6. 6. Aim <ul><li>Develop an autonomous </li></ul><ul><li>Agent based solution for </li></ul><ul><li>maintaining environment </li></ul><ul><li>sustainability </li></ul>
  7. 7. Objectives <ul><li>Study of the existing environmental issues. </li></ul><ul><li>Study of technologies that can solve the problem </li></ul><ul><li>Design and Develop an Agent Based Solution for environment sustainability – Hydroponics environment has been used as the test environment </li></ul><ul><li>Evaluation of the solution </li></ul>
  8. 8. Adopted Approach – Using Swarm of Agent for a sustainble Environment <ul><li>A multi agent system to emulate process in hydroponics environment </li></ul><ul><li>Enable passing messages to establish negotiations among environmental factors to achieve the environment sustainability </li></ul>
  9. 9. Our solution, SAS_EN
  10. 10. Decision Architecture Temperature control Agent Water control Agent Ontology Message Agent Nutrient control Agent Actuators Sensors Ec measure Water level measure P H measure Temperature measure Valves Fan Light Pumps
  11. 11. Features & Advantages <ul><li>24/7 monitoring of the system(Ec value, P H value, temperature etc.) </li></ul><ul><li>Autonomous emergent decision making </li></ul><ul><li>Self controlling of the inputs to the system (Water level, nutrient solution, heat & ventilation) </li></ul>
  12. 12. Uniqueness of the SAS_EN approach Traditional Automation Our approach Pre-programmed behavior Emergent behavior Reactive Proactive Not adaptive Adaptive Needs a PC No need for a PC Periodic adjustments Dynamic adjustments Depend on a pre-specified algorithm Depend on the interactions between Agents
  13. 13. Technical Overview
  14. 14. Usage <ul><li>Cost of the system around $ 300 </li></ul><ul><li>Easy installation </li></ul><ul><li>Intervention required from the owner is minimum </li></ul><ul><li>Ability to operate manually in case of a power failure </li></ul>
  15. 15. Evaluation Performance evaluation criteria Managed by the embedded solution Managed manually Yield Yield was high. Also there were only few perishable items. (1.5% yield was perishable ) Yield is average. There were many perishable foods. (2.5% yield was perishable ) Labour hours 2 labour hours per day 16 labour hours per day Money Initial cost, electricity cost Labour cost, Rework cost Reliability Reliable Reliable Response time Very High Average Usability Very High Average
  16. 16. Flashback <ul><li>Addressing the Environment sustainability </li></ul><ul><li>Enhancing an alternative agricultural method </li></ul><ul><li>Provide proactive and autonomous capabilities to a Hydroponics system </li></ul><ul><li>Enables a Hydroponic system to sustain amidst rapid environmental changes </li></ul>
