Structural Control Policies (SCPs) are real-time flexible manufacturing system (FMS) operating policies that guarantee deadlockfree operation. SCPs must be correct and scalable. A correct SCP guarantees deadlock-free operation whereas a scalable (polynomial) SCP remains computationally tractable as FMS size increases. The NP-completeness of state safety (is there a sequence of state transitions leading to the empty state?) implies that a correct and scalable SCP will reject some safe states. ...

Analysis of static complexity.(Special Issue of Design & Manufacturing on Virtual Manufacturing)(Complexity in Manufacturing Systems, part 1)
IIE Transactions ; 1. Introduction Manufacturing systems are often described as being complex [1,2]. The dynamic nature of the manufacturing environment greatly increases the number of decisions that need to be made and system integration makes it difficult to predict the effect of a decision on future system
Design and operation of manufacturing systems: the control-point policy.
IIE Transactions ; This paper synthesizes recent work by the author and his colleagues on the performance analysis of manufacturing systems and on real-time scheduling methods. It describes a decentralized scheduling/control policy and proposes a method for analyzing the performance of systems that are operated
Stochastic Models of Manufacturing Systems
INFOR ; This book is probably the first to focus on stochastic models of a variety of types of manufacturing systems. Many stochastic models are presented to analyze How lines, automatic dedicated transfer lines, job shops, flexible transfer lines, flexible manufacturing systems, flexible assembly systems,
The case for modeling correlation in manufacturing systems.
IIE Transactions ; TAYFUR ALTIOK [1] BENJAMIN MELAMED [2] Manufacturing-related models have traditionally made independence assumptions on associated stochastic processes in order to achieve tractability of analytical models and simplify Monte Carlo models. This paper aims to alert users to potential deleterious
