摘要:AbstractThe objectives of this study are to develop an efficient and generally applicable multi-criteria methodology for choosing the optimal ultrasound device, and to apply it to a case study. The methodology is based on Analytic Hierarchy Process with a Goal (to satisfy company’s objectives in terms of ergonomics, i.e. to optimise workers’ well-being) and three levels of evaluation elements. It provides decision-makers of hospitals or diagnostic centres with a structured methodology to select the most ergonomic ultrasound. The case study considered a wireless, a mobile and a traditional ultrasound device in an Italian hospital. The wireless device was the preferred one.
