Abstract [en]

Objective: To assess uncertainty in cost estimates for collecting posture data by inclinometry, observations and self-report.

Method: In a study addressing physical workloads at a paper mill, costs were calculated for measuring postures of twenty-eight workers during three shifts. Uncertainty in cost was assessed for all three methods as the range between an assumed best case (lowest cost) and worst case (highest cost) using scenario analysis.

Results: The cost of observation was most uncertain (€19089- €87154). Self-report costs were least uncertain (€3941- €27473), and cost for inclinometry was €8567 and €60313 in best and worst case, respectively.

Conclusions: The extent of uncertainty in cost estimates implies that observation could be less expensive than inclinometry, e.g., when experienced observers use existing software, while inclinometers need to be purchased. We propose adding uncertainty assessments to cost estimates when selecting a method for measuring working postures.
