The prefabricated building process offers undeniable advantages and benefits over conventional building techniques. However, the production process for panelised homes is highly variable and the production time for a single home can vary significantly. This paper presents a case study of an established panelised home manufacturer. In the current state, their floor panel production line is identified as having a lower productivity than the rest of the production line, and thus is an area with potential for improvement. To complement the onsite observation, video recordings are captured of the production area, which allows for the collection of more detailed data. The use of simulation will be investigated in this paper to model a floor panel production line in a panelised home manufacturing facility. After evaluating the currentstate performance, several proposed changes will be validated in terms of whether or not they should be implemented in the case study manufacturing facility.
