improving contact lens manufacturing through cost modeling and batch production scheduling optimization
J&J Vision Care (JJVC) uses production scheduling methods that are not fully optimized, causing over-production of certain SKUs, and reducing capacity for other SKUs on backorder. This makes planning a weekly run-schedule for each line difficult. It is also difficult to understand where to invest …

Optimisation of CHO Cell Line Development Using Hybrid Modelling for Antibody Therapeutics
Scaling up pharmaceutical production processes is an intricate and resource-intensive task, often starting inefficiently at the smallest scale. This approach is costly, time-consuming, and unsustainable, particularly for personalised medicines and biotherapeutics, which hold the potential to be the …

Continuous production of conducting polymer
… muscle applications. The objective of continuous production was to produce both larger films and films with more consistent properties than the films produced by the current batch-production method. The mechanical properties of polymers produced by batch synthesis are known to be highly dependent …
