Research Topic Research topic of my Ph.D. thesis
is focused on the Development and Applications
of the Method MFD (Modular Function Deployment)
for Increasing the Competitiveness of Machine
Tools. Research Questions 1. What is the lack
in the current MFD approach ? 2. How the MFD
method could be advanced ? 3. How can I use
computer aid for MFD method ? 4. How can I verify
(apply) results of the advanced MFD method
? Necessary Theories 1. Theory of Structures,
Properties, and Quality of Technical Systems
(TS) 2. Design for Properties (DFX) 3. General
Procedural Model of the Design Process Approach I
n general there are three levels of knowledge
support of engineering design process (intuitive,
methodical and systematic one). The intuitive
approach We have no theories, no methods,
only previously acquired general and specialized
knowledge and practical experience. In this case
e.g. the scope of considered properties of the TS
depends only on intuitive decisions of
engineering designers. The methodical approach
We have prescriptive and normative instructions,
which restrict space for creative design process,
e.g. BS 2000, VDI 2221. According to my analyses
MFD exists up to now on this level. The
systematic approach We have system of pieces of
knowledge and their relations, which enables to
manage and optimally support creative design
process. I plan to advance MFD to this level with
use of the above mentioned theories. In the area
of computer support my goal is development of a
program, which will guide engineering designer
through procedural phases of design process and
help him to solve these phases more
systematically, flexibly and effectively. I will
verify the advanced MFD method in the area of
frames for machine tools. I will focus on
development and evaluation of their optimal
modules.
