Process Industrial Engineering

Process Improvement - Gilbreths' View

Frank Gilbreth developed process analysis and improvement also along with motion study. In 1921, he presented a paper in ASME, on process charts. Lilian Gilbreth was a coauthor of this paper.

At the end of the paper, the conclusion made is as follows:

The procedure for making, examining and improving a process is, therefore, preferably as follows:

a.  Examine process and record with rough notes and stereoscopic diapositives the existing process in detail.

b. Have draftsman copy rough notes in form for blueprinting, photographic projection and exhibition to executives and others.

c. Show the diapositives with stereoscope and lantern slides of process charts in executives' theater to executives and workers.

d. Improve present methods by the use of —
1 Suggestion system
2 Written description of new methods or 'write-ups," "manuals," ''codes," ''written systems," as they are variously called
3 Standards
4 Standing orders
5 Motion study
6 Micromotion studies and chronocyclegraphs for obtaining and recording the One Best Way to do Work.

e. Make process chart of the process as finally adopted as a base for still further and cumulative improvement.

We see in the method described above the method study steps of record, and examine. The practice of involving the workers in analyzing the process chart which was later popularized by Alan Mogensen is also present in the method suggested by Gilbreth to improve a process.  Motion study as a later step in the process analysis method, which was emphasized by H.B. Maynard as part of the operation analysis proposed by him is also visible in the procedure described by Gilbreths.

H.B. Maynard proposed "Operation Analysis" for process improvement.

So, we can see the methods engineering and methods study which became popular subsequently were futher development of Gilbreth's process improvement procedure only.

Process Engineering

Process engineering focuses on the design, operation, control, optimization and Intensification of chemical, physical, and biological processes. Process engineering encompasses a vast range of industries, such as chemical, petrochemical, agriculture, mineral processing, advanced material, food, pharmaceutical, software development and biotechnological industries.

Process Industrial Engineering

Process engineering is an established term in engineering. Hence process industrial engineering, which represents the redesign of processes by industrial engineers to improve productivity is an appropriate term.

Methods Engineering, Operations Analysis, Method Study and Motion Study are various methods or procedures of process industrial engineering.

The process industrial engineering has to develop analysis and improvement of technical elements of a process in more detail to make industrial engineering an engineering based activity to increase productivity in engineering organizations, departments and activities.

Process industrial engineering also includes improvement of related management activities. F.W. Taylor was a pioneer in introducing many changes in management practices to improve productivity. Industrial engineering adopted the same objective. So within process industrial subject area comes the function of management process industrial engineering.
