Abstract: The aircraft component manufacturing industry can be considered a high value manufacturing value chain, due to the nature of the delivery space. South Africa currently supplies various components into the international aerospace industry. A key strategic operational toolset is the theory of constraints (TOC) manufacturing methodology. This research propositions a review and optimisation of the current mode of operation (MOO) specific to work in progress (WIP) management. A simulation-based approach is adopted to test the scenarios for potential work schedule optimisation, including incorporation of the TOC principals. The results are insightful, specific to throughput and cost management. The research and simulation serves as a significant opportunity for the company to integrate and optimise leading towards Industry 4.0 delivery.

Keywords: manufacturing systems; Industry 4.0; theory of constraints; TOC; multimethod simulation modelling; production optimisation.
