|Abstract or Summary
- The main objective of this thesis is to investigate the microprocessor's
potentials to improve the productivity of Industrial
Engineers engaged in work design and measurement. More exactly, the
following four hypotheses were proposed and investigated:
(1) A Universal Time Data (UTD) structure could be used to
accommodate a variety of industrial needs.
(2) The data files created according to the Universal Data Base
structure should be accessed and edited by the analyst much
like the word processing machines used by office clerks.
(3) The programs developed could be written, compiled and stored
onto 4096 bytes of Read Only Memory available in the computer.
(4) The timer functions of microprocessors could be used not only
to measure and record time, but also to real-time simulate
activities and output signals in order to control light panels
and a speaker.
The thesis is comprised of two papers. The first paper, entitled
"Microprocessors in Work Measurement: A Productivity Tool for MTM
Analysts," comprising Chapter II of this thesis, is a tutorial
introduction to the use of microprocessors to work analysis and design
using the MTM predetermined time method.
The second paper, entitled "Design of a Universal Time Data
Structure for Work Measurement and Design," is included in Chapter
III of this thesis, and specifically addresses the above four hypotheses.
The set of programs developed have the ability to make the microcomputer
operate as a multi-activity stopwatch, create the UTD files
that are compatible with the microcomputer's Text Editor, inform the
user of the additional observations needed to reach a given confidence
level and interval, perform real-time simulation of the files, and generate
MTM files and simograms.
The future areas of research include: more extensive uses of the
I/O ports to further assist Industrial Engineers, incorporation of work
sampling program, more extensive time data tables (including MTM-2,
MTM-1, robot action tables, etc.), testing of the practicality of the
developed system under actual industrial work conditions. Matching
microprocessor and video-tape capabilities presents another challenging
dimension to Industrial Engineering productivity.
