In spite of a long history of profound research on manufacturing systems, researchers have
rarely explored the aspect of integrating the two key components of manufacturing systems:
production system and material-handling system (MHS). Often they have focused on one
component while ignoring the other. During the decision-making process both components must
be considered in order to achieve overall improved productivity. Therefore, a generic theory,
considering both key components, is proposed (Chapter 2) for defining and classifying the current
state of the manufacturing system into a logistics constrained state (LCS), a transition state (TS),
and a production constrained state (PCS). In Chapter 3 methodologies for identifying the current
state of manufacturing systems as well as for identifying the transition from one state to another
are proposed. The effect of number and load carrying capacity of the material handling units
(MHUs) on the three proposed states is analyzed. In Chapter 4, the effect of variability in
processing times on the three manufacturing system states is investigated. The MHS is an integral
part of the manufacturing system, and the available related literature mainly concentrates on
scheduling, routing, and determining the required number of MHUs. Rarely has any literature
considered the failure of MHUs. Chapter 5 explores the impact of different failure patterns of
MHUs, and their effect on the performance of a manufacturing system is investigated. A cost
analysis is performed to identify the most cost-effective failure pattern and the required number of
MHUs for the manufacturing system, assuming that, failure patterns are known in advance.
