INDUSTRIAL ENGINEERING DEFINED

Industrial Engineering is concerned with the design,

installation and improvement of integrated systems of

people, materials, information, equipment, and energy.

It draws upon specialized knowledge and skill in

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.


8/37

INDUSTRIAL ENGINEERING DEFINED

In simpler words, I.E.s design industrial

systems.

SYSTEMS DESIGN

How well the I.E. performs the mentioned

design tasks determines to a very great extenthow efficiently and effectively the

organization will operate

Very difficult!

Few I.E.s really engage in overall system

design. :(

EFFECTIVE MEASURES FOR THE I.E.

FUNCTION

Objectives of the I.E. function must be set

by management in accordance with themission the function is expected to

accomplish

Should be measurable

Repetitive vs project-based

Periodic checking (actual vs goals)


28/37


FUNCTION

Typical objectives of I.E. department

A. Repetitive activities Achieve cost savings in direct labor equal to three

times the departmental budget

Reduce direct man-hour labor content of

production by 10%

Reduce mfg time through improve methods by 7%


29/37


FUNCTION


A. Repetitive activities Obtain participation of 50% of workers in cost

reduction program

Reduce the cost of setting time standards by 10%

Reduce in-process inventory by 8% Attain 96% accuracy in management reporting


30/37


FUNCTION


B. Project-based Overhaul unit #3 at a cost not exceeding

PhP300,000

Rearrange production equipment to achieve a 15%

decrease in flow time

Complete project no later than November 27 at a

cost not greater than PhP36,000
