Improving RFID adoption in Taiwan's healthcare industry based on a DEMATEL technique with a hybrid MCDM model
Introduction
Radio frequency identification (RFID) is a communication technology that uses radio waves to exchange data. RFID has three components: (1) an antenna for transmitting and receiving signals; (2) a transponder programmed with the identification information; and (3) an RF module (reader) with a decoder or transceiver. RFID has many applications and is an increasingly valuable tool for enabling automatic identification and management. For many industries, RFID is not only a new alternative to existing tracking methods but is also a solution for a range of previously cost-prohibitive innovations in internal control and supply chain coordination [34], [46].
RFID has existed for decades. This technology was originally used to identify and track flying aircrafts during the Second World War. Until recently, RFID was deemed to be too expensive and limited in functionality for many commercial applications. As the prices of RFID equipment and RFID tags have dropped in recent years, RFID applications have become increasingly prevalent. Cost is no longer a barrier. However, RFID has not been extensively adopted by the healthcare industry. The relatively conservative attitudes of healthcare providers have prevented hospitals from using the latest information technologies. Furthermore, technology adoption often depends on a critical mass being reached; a manager's decision to adopt a new technology often depends on the technology's diffusion rate, which, in turn, depends on the decisions made by other managers. Furthermore, even if a hospital decides to evaluate the relative costs and benefits of implementing RFID technology, no comprehensive evaluation and adoption model exists that can be used as a reference for the adoption of RFID in the healthcare industry. Thus, it is inappropriate to focus only on the cost of a new IT technology as the primary factor in its adoption [4], [7], [9], [50].
Most of the conventional multi-criteria decision analysis (MCDA) models cannot handle the analysis of complex relationships among different hierarchical levels of criteria. However, the decision to adopt RFID requires a decision model that performs just that analysis. In this paper, we develop a hybrid MCDM model called DDANPV that combines DEMATEL, DANP, and VIKOR. DDANPV overcomes the limitations of existing decision models and can be used to help us analyze the factors that influence industry adoption of RFID technology. In particular, we use Taiwan's healthcare industry as an example to study the interdependence of the factors that influence the adoption of RFID in the healthcare industry, as well as to evaluate alternative RFID adoption processes to achieve the desired levels of performance from RFID technology.
This paper is organized into five sections. Section 2 reviews the literature on the implementation of RFID in the healthcare industry. We will discuss the advances in evaluating the RFID adoption process, the selection criteria for adopting RFID technology, the decision models currently being used to determine whether RFID technology should be adopted, and the specific problems related to evaluating the RFID adoption process. Section 3 introduces the hybrid MCDM method called DDANPV. In Section 4, we use Taiwan's healthcare industry as an empirical example to illustrate how DDANPV could help select the best RFID adoption method and discuss the results. In Section 5, we draw conclusions.

The effects of evaluating the RFID adoption model in the healthcare industry
The purpose of this section is to survey the relevant studies in the RFID adoption process, to investigate and compare various evaluation frameworks, and to identify possible factors that influence the RFID adoption process in the healthcare industry. Due to the lack of previous research on the criteria used in evaluating RFID for adoption, this study expands upon a general evaluation framework used in other industries and compiles four primary factors—technology, organization, environment and
DDANPV — A hybrid MCDM model for evaluating and improving RFID adoption
DDANPV is comprised of three stages. First, we use the DEMATEL method to uncover the relationship between the criteria and their network structure in the presence of interdependence and feedback among criteria. DEMATEL is more suitable in real-world applications than traditional methods, which assume independence among criteria [8], [14], [15], [23], [24], [33], [43]. Second, we combine DEMATEL with the ANP method to form DANP (DEMATEL-based ANP) to obtain influential weights for each dimension
An empirical case study on RFID adoption in Taiwan's healthcare industry
In this section, we present an empirical study using the proposed DDANPV model to evaluate, select, and improve upon the best alternative for RFID adoption in Taiwan's healthcare industry.
Conclusions
The dimensions and criteria outlined in this study serve as bridging mechanisms for the evaluation of RFID adoption processes. Prior literature has identified the dimensions and criteria that influence the evaluation of adopting RFID. The main contributions of this study are twofold. First, the evaluation of technology adoption is a decision-making problem that is composed of complex dependences and interactions. In this paper we used previous studies to develop a TOEC framework to evaluate
