The objective of this thesis is to make a study of the design
methodology and the structure of the control algorithms for FMS for
rotational parts. The work is divided into three main parts. In the
first part, the several types of manufacturing systems are defined,
the relation between FMS and manufacturing division in the total
manufacturing organisation is identified and the elements composing
an FMS are analysed.
In the second part, the design methodology for an FMS is divided
into a number of steps and the importance of simulation techniques in
assisting the decision making is identified. A generalised simulation
model, written in the ECSL language which can be used for a variety of
systems, is described. The main characteristics of an FMS for rotational
parts are attributed to the several entities included in the model.
In the third part of the thesis the several levels of control
for an FMS are identified and the study of several priority rules
forming the control for an FMS are identified and the study of several
priority rules forming the control strategy is made by the use of a
hypothetical model configured on the basis of a realistic parts spectrum
of disc shaped parts. The flexibility of the system to several
disturbances is also assessed. The structure and dimensioning of
robot operated systems and the relation between robot utilisation and
system performance is also examined.
