“…A pull mechanism explicitly controls the WIP in the system. Other dynamic production control policies, based on indirect WIP control activated by workstation processing rate adjustments, are proposed in [14,176,281,130]. These policies have been traditionally compared in terms of production logistics performance and due-date performance.…”

“…Further, some significant research works for the chaotic behavior in manufacturing have been conducted in [5][6]. Little more extension in this direction is also found for the assessment of fidelity of control-theoretic models of WIP in autonomous work systems [7]. Furthermore, a nonlinear dynamics approach to model the complexity of a manufacturing system can be found in [8] whereas a nonlinear characterization of the performance of production can be found in [9].…”

The purpose of the present work is to study the chaotic behavior in a flexible assembly line of a manufacturing system. A flexible assembly line can accommodate a variety of product types. Result analysis is performed to obtain time persistent data. The behavior of the system is observed for Work-In-Process, as assembling systems are sensitive during processing. It is found that the average Lyapunov exponent is positive in the considered case, and thus chaotic behavior may be present in flexible assembly lines.

“…Moreover, policies for the real-time control of machine parameters, i.e. the processing rates, to regulate the work in process have been proposed (Ma and Koren, 2004), (Toshniwal et al, 2004). Although these policies allow to reduce the production lead time, no direct control of this performance measure is performed.…”

The ability of meeting the target production lead times is of fundamental importance in modern manufacturing systems producing perishable products, where the product quality or value deteriorates with the time parts spend in the system, and in manufacturing contexts where strict lead time constraints are imposed due to tight shipping schedules. In these settings, traditional manufacturing system engineering methods and token-based production control policies loose effectiveness as they aim at achieving target production rates while minimizing the inventory, without directly taking into account the effect on the lead time distribution. In this paper a production control policy for unreliable manufacturing systems that aims at maximizing the throughput of parts that respect a given lead time constraint is proposed for the first time. The proposed policy jointly considers the actual level of the buffer and the state of the second machine in the system and stops the part loading at the first machine if there is unacceptable risk of exceeding the lead-time constraint. The effectiveness of this new policy against the traditional Kanban policy is quantified by numerical analysis. The results show that this new policy outperforms the Kanban policy by providing a tighter control on the production lead time. This approach paves the way to the introduction of new lead-time oriented production control policies to maximize the effective throughput in real manufacturing systems.
