2 TI 2111 Work System Design and Ergonomics TI 2111 – Syllabus

3 TI 2111 Work System Design and Ergonomics TI 2111 – Course Description Survey of Industrial Engineering methods for measuring, evaluating, and improving performance of work systems in organizations. Introduction to Ergonomics with an emphasis on human capabilities and limitations. Discussion of application of Industrial Engineering and Ergonomics design principles to redesign workstations, work tasks, and work environments.

4 TI 2111 Work System Design and Ergonomics TI 2111 – Course Objectives Describe the role of Work measurement & Ergonomics in the workplace Conduct a methods engineering study of a particular job, including methods analysis, time studies, and work sampling studies. Apply industrial engineering and ergonomics / human factors design principles to the analysis and redesign of an existing work station, work task, piece of equipment, work environment, etc.

6 TI 2111 Work System Design and Ergonomics Course Topics Introduction: Definitions, historic review, motivation Work System Design  Definitions, objectives and performance measures  Time study: methods & equipment  Performance Rating and Allowances  Standard Times  Predetermined Time Systems  Work Sampling Ergonomics  Introduction  Visual, Auditory, Cognition  Display and Control  Biomechanics, Physiology

7 TI 2111 Work System Design and Ergonomics Grading (subject to change) Course RequirementPercentage of grade Examinations (2) 60% Quizzes 10% Homework (2) 15% In-class activities 15% Class participation Bonus

8 TI 2111 Work System Design and Ergonomics Miscl. Regular class attendance and participation This class is designed to allow students to apply the concepts, no one correct solution All written assignments will be graded on the quality of the work. It is expected that each student will provide well-written and defended solutions to the problems for this class. Only legible handwriting will be graded. If you have a dispute about a grade for any assignment or examination, provide the instructor with a written explanation no later than 1 week after the work was returned to you. I do make mistakes, so please don’t hesitate to bring them to my attention. I will strive to make this an exciting class. I welcome your suggestions for improving the course at any time.

9 TI 2111 Work System Design and Ergonomics Do’s and Don’t Do read the material before class... Do your homework … Ask questions … Don’t wait till the last minute … Don’t even think about copying others …

11 TI 2111 Work System Design and Ergonomics 1. Introduction

12 TI 2111 Work System Design and Ergonomics Industrial Engineering ? 1948: American Institute of Industrial Engineering (AIIE) (www.iienet.org)www.iienet.org …is concerned with the design, improvement, and installation of integrated systems of people, material, information, equipment, and energy. It draws upon specialized knowledge and skills in the mathematical, physical, and social sciences together with the principles and methods of engineering analysis and design to specify, predict, and evaluate the results to be obtained from such systems....is concerned with the analysis, design, installation, control, evaluation, and improvement of socio-technical systems in a manner that protects the integrity and health of human, social, and natural ecologies. A socio-technical system can be viewed as any organization in which people, materials, information, equipment, procedures interact in an integrated fashion

13 TI 2111 Work System Design and Ergonomics Modern industrial organization - Increasing competition (increased number of competitors) - Stiffer requirements for international competitiveness (i.e. ISO standards) - High sophistication in quality of products demanded by customers - … Productivity Quality Efficiency Effectiveness Safety Comfort

14 TI 2111 Work System Design and Ergonomics “We are in a new economic age. We can no longer live with commonly accepted levels of delays, mistakes, defective materials and defective workmanship.” W. Edward Deming, 1968

15 TI 2111 Work System Design and Ergonomics Performance measures

16 TI 2111 Work System Design and Ergonomics Ways to improve performance of a work system: Improved layout, workflow, and material handling Training Work simplification Job/tools redesign Improved work environment Workers selection Methods Standards Work design Ergonomics

17 TI 2111 Work System Design and Ergonomics Work System Design (& Ergonomics) – “PSK&E” Purpose : To increase productivity in industry, while maintaining worker health and safety thru:  Work Measurement  Methods Engineering Continuous and repetitive process  Work measurement (e.g. Time study) A process for measuring …  Work Methods Systematic procedure for analyzing a given task

18 TI 2111 Work System Design and Ergonomics TTCK → PSK&E (Sutalaksana, 1979)

19 TI 2111 Work System Design and Ergonomics “PSK&E” - Objectives Minimize times (Fig. 1.2) Improve quality and reliability Minimize direct and indirect material cost Maximize the safety and well being of the workers Increase job interest and satisfaction for the workers

20 TI 2111 Work System Design and Ergonomics PSK&E - Applications Design and improvement of work methods Establish a standard work methods and standard time Training & Workers selection Lay-out design Economic analysis, costing, task evaluation Reward & workers motivation Production planning and control Product design …

21 TI 2111 Work System Design and Ergonomics Historical Development The origin of time study  Frederic W. Taylor  Frank Lillian Gilbreth  Henry L. Gantt  Henry Ford  Elton Mayo

22 TI 2111 Work System Design and Ergonomics Frederic W. Taylor ( ) Founder of the ‘Scientific Management’ term Emphasized on:  Increasing throughput  Reducing manufacturing costs  As a result, increasing workers’ salaries Tools (how to do the above):  Divide the task into small elements  Separate the non-required from the required elements  Setting standards: time, quality, methods.  Specialization: training for a specific job
