1. Queueing-Theoretic Models for “Push” and “Pull”/CONWIP-based Production Lines

2. Intended Usage Estimation of various performance indices, e.g.,
expected lead times and accumulated WIP in case of “Push” systems;
expected lead times and throughput in case of “Pull” systems.
Design aids: identifying pertinent and cost-effective configurations that can attain target performance values.
Providers of analytical insight regarding the dynamics of the considered systems and of diagnostic capability

3. Plan of Work
Modeling of “push”-based flow lines as series of G/G/m queues operated at a certain throughput rate.
Modeling of CONWIP-based lines as closed queueing networks.
Modeling of the impact of preemptive and non-preemptive disturbances by revising the applied processing times.
A design example
Analyzing the impact of batching and blocking effects
A systematic comparison of “push” and CONWIP-based systems according to the derived formal models
A production planning framework for repetitive manufacturing environments controlled by CONWIP flow lines
