Key Determinant Derivations for Information Technology Disaster Recovery Site Selection by the Multi-Criterion Decision Making Method

Abstract

Disaster recovery sites are an important mechanism in continuous IT system operations. Such mechanisms can sustain IT availability and reduce business losses during natural or human-made disasters. Concerning the cost and risk aspects, the IT disaster-recovery site selection problems are multi-criterion decision making (MCDM) problems in nature. For such problems, the decision aspects include the availability of the service, recovery time requirements, service performance, and more. The importance and complexities of IT disaster recovery sites increases with advances in IT and the categories of possible disasters. The modern IT disaster recovery site selection process requires further investigation. However, very few researchers tried to study related issues during past years based on the authors' extremely limited knowledge. Thus, this paper aims to derive the aspects and criteria for evaluating and selecting a modern IT disaster recovery site. A hybrid MCDM framework consisting of the Decision Making Trial and Evaluation Laboratory (DEMATEL) and the Analytic Network Process (ANP) will be proposed to construct the complex influence relations between aspects as well as criteria and further, derive weight associated with each aspect and criteria. The criteria with higher weight can be used for evaluating and selecting the most suitable IT disaster recovery sites. In the OPEN ACCESSSustainability 2015, 7 6150 future, the proposed analytic framework can be used for evaluating and selecting a disaster recovery site for data centers by public institutes or private firms.

“…Research indicates that the ANP technique can strongly consider the necessary formation for uncertain pairwise comparisons [43,[48][49], and it is also able to provide much better explanations in multi-decisionmaking procedures [47,50]. Generally, in ANP procedure fi rst and foremost, a specifi c vector, w, should be calculated by the equation:…”

Disaster Recovery Site Evaluations and Selections for Information Systems of Academic Big Data

“…Few studies have carried out on the selection of DR sites using the hybrid MCDM model combining with DANP and VIKOR. To date, only Yang et al (2015) have studied the consideration factors concerning DR site selection for data centers. Therefore, this research adopts the consideration factors guideline from Yang et al (2015) and uses a real Big Data DR application of an Asian high-performance computer center's evaluation and selection of DR sites to illustrate the feasibility of the proposed framework.…”

“…Such an infrastructure significantly increases the risks to responses to disaster (Clitherow, Brookbanks, Clayton, & Spear, 2008). Information infrastructure availability has become a critical issue for DR (Yang, Yuan, & Huang, 2015). A comprehensive approach to business continuity planning seeks to mitigate all major interruptions of business systems with backup systems.…”

“…Clitherow et al (2008) considered the DR site not as geographically separated, but as having spare capacity to ensure that all required applications can operate in either of the facilities in the event of the loss of the other facility, replication of data between the data centers, high levels of physical and network security, and a safe system for storing data. Yang et al (2015) examined the consideration factors of DR site selection from five perspectives: location and infrastructure, IT facility, DR objectives, DR readiness exercises, and operation management.…”

“…For example, the U.S. National Institute of Standards and Technology (NIST) enacted regulations of the SP 800-34 in 2006, which require high-and mediumlevel public sectors to set up DR sites (Bowen, Hash, & Wilson, 2006). International standards related to information system DR include those from the International Standard Organization (ISO 22301, ISO 22313), International Electro-technical Commission (IEC 27001, 27002, 27031), and International Telecommunication Union (ITU -TL.92, ITU-T L.1300) (Yang et al, 2015). These regulations and international standards lead to a number of drivers and requirements to minimize the exposure to IT operational risk, improve IT operational resilience, and support the goal of continuously available IT service, as applied to the infrastructure.…”
