Model Based Approach of Integrating Spatial and Temporal Tools compared to traditional Time Studies

Abstract

This work aims to demonstrate the use of CAD-based workplace models that describe the spatial relationships of a given job and the use with Predetermined Time Systems (PTS) - namely MODAPTS - in lieu of traditional time studies. MODAPTS was chosen for this work as it is widely used and has relative simplicity. This work shows that CAD and PTS models can be combined in an underlying model for predicting work time and work methods that can then be used for interpreting various fatigue risks. It also gives insight on where MODAPTS categorization of movement patterns falls short, and provides taxonomy updates so that a model-based approach can more accurately reflect the job. It also provides a framework that can serve as a foundation for interpreting observation-based results, for identifying specific risk factors, and for designing engineering interventions.
