The impact of redundancy on resilience engineering in a petrochemical plant by data envelopment analysis

Abstract

Resilience engineering is a new and proactive attitude toward improving the safety and reliability of complex industrial systems such as oil and gas companies and petrochemical plants. This study aims to evaluate the effect of redundancy on a resilient system and determine which redundancy in different aspects including human resources and equipment items (hardware, software, and information) is more efficient in a resilient system through data envelopment analysis. Data collection was performed in a petrochemical plant through a questionnaire. Then, reliability of the data was calculated through Cronbach's alpha test. Next, the effects of human redundancy and equipment redundancy on resilience engineering are examined by means of data envelopment analysis approach. The results show that efficiency of the resilient system is improved by considering both equipment redundancy and human redundancy. It is also revealed that human redundancy is more effective in resilient system performance compared to equipment redundancy. Hence, human redundancy plays a vital role in efficiency enhancement of resilient systems. This study is among the first ones that investigate the impact of the redundancy in resilient systems in different aspects including human and equipment redundancy by means of data envelopment analysis approach and highlights the gaps between managers and staff about the impact of equipment redundancy and human redundancy on resilience engineering.

Impact of risk management culture on supply chain resilience: An empirical study from Indian manufacturing industry

“…11,17 For example, Ambulkar et al, 12 Brandon-Jones et al, 6 and Gölgeci and Ponomarov 26 regard SC resilience as a unidimensional construct, however, Wieland and Marcus Wallenburg 8 argue that it represents agility and robustness. Similarly, researchers like Azadeh et al, 30 Hohenstein et al, 11 Johnson et al, 20 Scholten and Schilder, 23 Roberta Pereira et al, 10 and Pettit et al 31 used even different constructs. For example, Scholten and Schilder 23 use the following three constructs of SC resilience: risk awareness, SC re-engineering, and knowledge management.…”

“…For example, Scholten and Schilder 23 use the following three constructs of SC resilience: risk awareness, SC re-engineering, and knowledge management. Azadeh et al 30 used velocity, visibility, flexibility, and robustness as constructs of SC resilience. Other constructs that have been used comprise collaboration, 10,20,23 culture and capacity, 11 collaborations, 10,11,20 information sharing.…”

Slack in Construction - Part 2: Practical Applications

“…A condition where some types of resources are provided in addition to the minimum necessary to perform a specific function (Nonaka, 1990), or when more than one resource performs a required function (Azadeh et al, 2016).…”

Survey assessment of organizational resiliency potential of a group of Seveso organizations in Turkey

“…As early as 1982, in his highly-cited paper, Meyer (1982) 27 noted that organizational resilience is influenced by an organization's strategy and its slack resources. Since then, many studies [28][29][30][31][32][33][34][35][36][37][38] support his resource-based view and in particular the need for redundant resources. Slack resources including financial instruments, enlargement of customer base, and development of conceptual slack (a term used for the total diverse analytical thinking ability of members of an organization on technology and processes) 6 are important.…”
