Simulation of the process of issuing the certificate of occupancy

In this paper, a discrete simulation model was developed for the certificate of occupancy (CO) for certain buildings issuance process in the Republic of Croatia. The model demonstrates the multistage nature of the process, with site inspections being the most time-consuming stage and a potential bottleneck. The model also shows that senior professional associates have the highest workloads. A what-if analysis was conducted to simulate the failure of the eDozvola system and to demonstrate the significant impact of such an interruption. A cost analysis of the CO issuance process demonstrated the potential for cost savings and efficiency gains through process optimization. Thus, simulation modelling can significantly improve the CO issuance process, resulting in cost savings, increased efficiency, greater stakeholder satisfaction, and better decision-making.
