| Abstract |
Discrete event simulation modeling for spatial analysis consists of a space markup model and a sequence model (flowchart). Space markup models are constructed in the form of network-based NbM and pedestrian-based PbM.
Although PbM is the modeling method for spatial analysis, this study intended to identify that applying the conventional NbM developed for production systems to spatial analysis may have a functional utility value to complement PbM. Therefore, this study used NbM and PbM to build the same model of a health examination center and obtained the following conclusions by comparing the simulation analysis results. 1) NbM and PbM did not show significant differences in the time required to examine 50 people and the time required per person, which means that the two modeling methods are compatible with each other. 2) The occurrence of queues, the primary cause of time delays, can be predicted by measuring resource utilization, which is a major clue in establishing optimal resource allocation and queue reduction plans. 3) NbM has advantages in the early stage of projects, such as space programming, and PbM is more advantageous for validation and analyzing the use of common spaces at the end of projects. |
