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.


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 …

1. Introduction


Industrial Engineering ?

1948: American Institute of Industrial Engineering (AIIE) (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


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

- …

“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


Performance measures


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

MethodsStandardsWork designErgonomics


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


TTCK → PSK&E (Sutalaksana, 1979)


“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


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 …


Historical Development

The origin of time study Frederic W. Taylor Frank Lillian Gilbreth Henry L. Gantt Henry Ford Elton Mayo


Frederic W. Taylor (1856-1915) 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
