The purpose of managing and improving the off-site construction process is to achieve better work flow in order to deliver the prefabricated products to the construction site at the right time. In this paper, a modelling process of the precast concrete manufacturing system using simulation technology is presented. The precast manufacturing system involves repetitive parallel labour-driven processes. A multi-shift work pattern for a set of workers is applied in each production process. Discrete-event simulation modelling is adopted to simulate such precast manufacturing systems. ARENA Rockwell simulation software is used as a tool in order to carry out the modelling issue. A simulation module limitation is addressed while modelling such labour-driven processes especially when using the current PROCESS module. In order to overcome this limitation, a special PROCESS template module is developed to enrich resources shift modelling capabilities in such simulation software. A case study is presented to validate and demonstrate the applicability of the developed PROCESS module in solving resource shift modelling issues in the precast labour-driven process production system. The results showed that the developed PROCESS module enabled efficiently modelling of different working shifts of workers.
