human machine system

  1. 1. Start with name of one who is most kind .
  4. 4. INTRODUCTION <ul><li>Ergonomics is the multidisciplinary subject and in order to be applied in a consistent and coherent way, a model or framework is required which specifies its areas of applications, boundaries and limitation. </li></ul><ul><li>Such a framework cannot be derived from the study of anatomy, psycholology, physiology alone since these sciences related with the human component but not as a human alone ….. </li></ul><ul><li>Several attempts have made to describe the role of human component in the work system with varying degrees of success but the most important and predominant work by LEAMON in 1980 with his model EMPERICAL MODEL OF HUMAN MAHCINE SYSTEM. </li></ul>
  5. 5. Display sensory Processing effectors control Environment Work organization Workspace LEMAN’S HUMAN-MAHCINE MODEL
  6. 6. <ul><li>Lemons human-machine model is computable with the work system framework presented here and has the advantage of providing a closer analysis of interactions b/w the human components and the rest of the work systems. </li></ul><ul><li>Lemons model was originally developed in the context of industrial ergonomics, but it is used more widely in the present discussion’s . </li></ul>Why LEAMON’S model ???
  7. 7. <ul><li>Human body is the part of the physical work and is obey all physical laws like all animated and unanimated object doing so …… </li></ul><ul><li>At this stage the over all goal of an ergonomics is to provide the optimum interaction b/w the human body to its physical surrounding so that got the physical requirement. </li></ul>HUMAN COMPONENTS OF WORK SYSTEMS
  8. 8. HUMAN COMPONENTS (continue…) <ul><li>At this stage it is very important to know the posture of the body and the forces ( internal and external ) subject to the body so that to know the effect to that forces on the body ….. </li></ul><ul><li>Human body is basically consist of </li></ul><ul><li>Joint skeleton </li></ul><ul><li>Muscles </li></ul><ul><li>Connective tissues </li></ul><ul><li>Sense organ and </li></ul><ul><li>Information processing system --- the brain . </li></ul>
  9. 9. 1- THE EFFECTORS <ul><li>There are basically three primary effectors … hand , feet and voice </li></ul>FEET HANDS VOICE
  10. 10. Effectors (continue..) <ul><li>The musculoskeletal system of the body part is regarded as a effectors in broad sense because no any purposeful activity is said to be done without the maintenance of posture and stabilization of joints. </li></ul><ul><li>The three effectors that we studied above are support by the musculoketal, physiological and information processing systems. </li></ul>
  11. 11. 1- THE SENSES <ul><li>Senses are the something through which we aware about the surroundings. </li></ul><ul><li>There are basically five senses. </li></ul><ul><li>However the existence of the 6 th senses is still debatable and controversial. </li></ul>
  12. 12. 3- SUPPORTIVE PROCESSES <ul><li>Human body in order to perform the work requires energy and information. </li></ul><ul><li>Brain the central processing unit and it provide the information to the different parts of the body so that the work is done. </li></ul><ul><li>Brain contain low level information so that to control the basic sensory activates and high level information in order to use in the planning, decision making and problem solving activities. </li></ul>
  13. 13. CONCULSION <ul><li>From the above study we declare the lemons model is really a computable approach to understand the ergonomics effects of human and machine components and their interaction. </li></ul><ul><li>Careful analysis of all such factors provides a approach to understand the human components in working environment….. </li></ul>
