A closed-looped modelling framework enables the assessment and analysis of the economics of manufacturing technology with alternatives. Initial steps involve conceptualising and modelling the process operations based on Process-based Cost Modelling (PBCM) approach. The next two steps involve carrying out sensitivity analyses of key parameters and understanding the behaviour of critical cost drivers. This establishes a set of characteristics which feedbacks to the technical team for process optimisation and the management for decision support making.
To penetrate the global market for microfluidics techonology, it is crucial to explore a low-cost and efficient manufacturing technology of microfluidic chips. Currently, plastic Injection Moulding (IM) process is widely used in the manufacturing of microfluidic chips. To reduce production cost and the lead time, a Roller-Embossing (RE) conceptual process is being proposed. However, to date, there is not much understanding of the economical performance of using RE in the fabrication of microfluidic devices.
To penetrate the global market for microfluidics techonology, it is crucial to explore a low-cost and efficient manufacturing technology (such as Roller-Embossing) of microfluidic chips. The assessment results from the closed-loop modelling methodology forecast the cost implications and help to understand the behaviour of critical cost drivers of a conceptual Roller-Embossing process. This is significantly useful for the industry to make technical and economical decisions in the development of commercially viable Roller-Embossing.
