An Approach to RTLS Selection

Abstract

Real Time Locating System has become an important part of supporting technologies applied in a wide range of logistics related to many sectors and branches, as warehousing, manufacturing or healthcare offering real time visibility of assets. It increases assets utilization. RTLS is a very wide term covering many different specific technologies. The use of a specific technology effects in achieving different performance metrics. Therefore, the selection of a specific technology (or mix) is multi-criteria decision making problem. A set of criteria for RTLS selection was discussed and confronted with a set of criteria for assessment of identification systems and an application of TOPSIS for the selection of RTLS was presented.

A Method for an Integrated Sustainability Assessment of RFID Technology

“…Three alternative real time locating systems were assessed using the linear scale. Their technological and organizational details were described in [49,51]. The resulting ranking confirmed previous rankings reported in [13,51], i.e., alternative 3 was superior to alternative 2, which was superior to alternative 1 (priorities using the standard linear scale: Alt3-54.3%, Alt2-25.7%, Alt1-20.0%, with CR MAX = 9.0%).…”

Priorities obtained in [13], also using AHP approach to the ranking, were 43.9% for Alt3, 32.9% for Alt2, and 23.2% for Alt1 (CR MAX = 8.9%).…”

“…However, the experts indicated that FSM and FCM may play an important role (FSM mostly informative, but FCM also controlling role) when more complex solutions are implemented. It was shown that both approaches (presented in this paper and in [13]) for sustainability assessment, however employing different criteria hierarchy (IMATOV based modules here, and TBL in [13]), deliver the same rankings as the pure technology-oriented selection process reported in [51]. The referred pure technology-oriented selection performed using TOPSIS delivered the following relative closeness measures: 0.256 for Alt1, 0.537 for Alt2, and 0.770 for Alt3.…”

“…The AHP-OS application was used for the computational procedure [50]. Three alternatives [51] (Alt1-Passive UHF RTLS, Alt2-Active Wi-Fi RTLS, Alt3-Active UWB RTLS) were assessed by two experts experienced in RFID deployments (with 10 years of experience in managing, designing, and analyzing over 50 deployments). For the decision hierarchy based on the IMAR approach, the results of global priorities of criteria were obtained using a standard linear scale (Table 4).…”

The feasibility and validity of using a real time location system (RTLS) to measure bedside contact time

“…RTLS technology has been used for decades in many industries to tag and track the location of goods or assets in the form of equipment and people (workforce and patients) in real time or as close as physically possible (Boulous and Berry, 2012;Elmer et al, 2019;Rainham et al, 2008). RTLS is a technology that has been applied in a wide range of logistics and has become a technology enabling the real time visibility of people or items in a defined geographical location that includes the hospital environment (Gladysz and Santarek, 2017). There are several types of RTLS locating systems: infrared, radiofrequency, ultrasound and hybrid solutions that combine infrared and ultrasound, Wi-Fi and bluetooth technologies.…”
