Abstract
Purpose
This study aims to establish an evaluation method for cross-regional major infrastructure project (CRMIP) supportability. The focus is to identify evaluation indicators from a complexity perspective and develop an evaluation model using qualitative and quantitative methods. Case studies are carried out to verify the reliability of the evaluation model, thereby providing theoretical and practical guidance for CRMIP operations and maintenance (O&M).
Design/methodology/approach
Guided by the idea of complexity management, the evaluation indicators of CRMIP supportability are determined through literature analysis, actual O&M experience and expert interviews. A combination of qualitative and quantitative methods, consisting of sequential relationship analysis, entropy weighting, game theory and cloud model, is developed to determine the indicator weights. Finally, the evaluation model is used to evaluate the supportability of the Hong Kong–Zhuhai–Macao Bridge (HZMB), which tests the rationality of the model and reveals its supportability level.
Findings
The results demonstrate that CRMIPs' supportability is influenced by 6 guideline-level and 18 indicator-level indicators, and the priority of the influencing factors includes “organization,” “technology,” “system,” “human resources,” “material system,” and “funding.” As for specific indicators, “organizational objectives,” “organizational structure and synergy mechanism,” and “technical systems and procedures” are critical to CRMIPs' O&M supportability. The results also indicate that the supportability level of the HZMB falls between good and excellent.
Originality/value
Under the guidance of complexity management thinking, this study proposes a supportability evaluation framework based on the combined weights of game theory and the cloud model. This study provides a valuable reference and scientific judgment for the health and safety of CRMIPs' O&M.

Abstract
Attempts to improve the quality of the products or systems which customers purchase have focused traditionally on improving the availability of the product through its reliability or maintainability characteristics. However, a growing awareness of the importance of integrating reliability and maintainability considerations into the design phase of a product has led to customers being unable to affect these characteristics to any great extent. As a result, supportability has emerged as a crucial concept to be considered if customers wish to enhance the quality of the products they purchase. Reviews some of the previous work on supportability, particularly in the areas where it is generally recognized that product owners can be most influential, namely spares estimation and shared capital investment equipment provision, and reflects on the associated impact on product quality.

Abstract
In the current drive to improve product quality through its reliability, maintainability and supportability characteristics, supportability has emerged as the key area in which customers can have an impact, the other two aspects being increasingly integrated into the product design phase. Previous work on supportability has indicated that product or system owners can be most influential in the areas of spares estimation and shared capital investment equipment provision. The effect of spares provisioning has previously been considered at some length. Presents the development of a mathematical model for estimating the impact of the level of shared capital investment equipment provided on the supportability. Such a model would then allow engineering practitioners to assess the implications of their decisions regarding resource allocation, in terms of the overall system availability.

Abstract
High reliability, maintainability, safety and supportability are expected from today’s modern systems. In the recent years supportability has been widely accepted as a major factor in logistics discipline. The main purpose of this paper is to demonstrate how advanced mathematical models can be used to analyse the effect of supportability on systems availability. The paper discusses supportability aspects and its effect on operational availability of complex systems using advanced mathematical models like Markov, semi‐Markov and non‐Markov models. The powerful mathematical models discussed in the paper would help reliability engineers and practitioners to predict the logistic support requirements to achieve specified operational availability.

Abstract
Purpose
Original equipment manufacturers (OEMs) start providing support to their products, that helped them in beating the competition across the worldwide. The unavailability of spares and crews may also prolong the downtime of equipment, thereby affecting the systems’ performance. The spares and crews have as much effect on the systems’ performance as the design characteristics (i.e. reliability and maintainability). Thus, the OEMs required to extent the support to their products through maintenance, spares, crews, etc., so as to gain the customer satisfaction.
Design/methodology/approach
The mathematical model for spares, crews and support quality has been presented in this research work. The problem has been identified from the literature perspective for mechanical systems.
Findings
The model has been implemented on a real-life problem, in which the OEMs provide support to their make installed at compressed natural gas workstation in National Capital Region, India.
Originality/value
The research proposed in this work will be helpful to manufacturer, customer, academician, researcher, industrialist and any concerned person, to get the exhaustive benefits from the system.

Abstract
Purpose
Manufacturing firms (MFs) nowadays are struggling to design and maintain an integrated product-service offer. This paper aims to explore the role of the supply chain (SC) in the design of the Product-Service System (PSS). In particular, the study focuses on the Design for Supply Chain (DfSC) approach in order to understand its role and contribution to the Design for Product Service Supportability (DfPSSu) approach in supporting PSS design.
Design/methodology/approach
Based on the multiple-case study approach, this paper used in-depth-interviews method to collect primary data from four multinational car manufacturers and two academic researchers.
Findings
The study reveals how a better design of the SC is required for the development of a service supportability approach that, in turn, facilitates the design of the PSS. Additionally, Internet of Things (IoT) technologies support MFs to analyse the ongoing development of the PSS business model. Finally, a better design of PSS is essential for strengthening the integration of Product and Service Offerings.
Practical implications
This study suggests that MFs can build dynamic SC capabilities to deal with fundamental changes that occurred when adopting servitization.
Originality/value
This paper is among the first attempts to study the design process of the PSS business model in a real business context taking into account different design strategies.

Abstract
Purpose
Resilience as a novel concept has attracted the most attention in the management of engineering systems. The main goal of engineering systems is production assurance and increasing customer satisfaction which depends on the suitable performance of mechanical equipment. “A resilient system is defined as a system that is resistant to disruption and failures and can recover itself and returns to the state before failure as soon as possible in the case of failure.” Estimate the value of the system’s resilience to increase its resilience by covering the weakness in the resilience indexes of the system.
Design/methodology/approach
In this article, a suitable approach to estimating resilience in complex engineering systems management in the field of mining has been presented. Accordingly, indexes of reliability, maintainability, supportability, efficiency index of prognostics and health management of the system, and ultimately the organization resilience index, have been used to evaluate the system resilience.
Findings
The results of applying this approach indicate the value of 80% resilience if the risk factor is considered and 98% if the mentioned factors are ignored. Also, the value of 58% resilience of this organization’s management group indicates the weakness of situational awareness and weakness in the vulnerable points of the organization.
Originality/value
To evaluate the resilience in this article, five indicators of reliability, maintainability, and supportability are used as performance indicators. Also, organization resilience and the prognostic and health management of the system (PHM) are used as management indicators. To achieve more favorable results, the environmental and operational variables governing the system have been used in performance indicators, and expert experts' opinions have been used in management indicators.

Abstract
Purpose
The purpose of this paper is to examine the relationship between the ethical culture of organisations and organisational innovativeness.
Design/methodology/approach
A quantitative empirical analysis was conducted on the basis of a survey of 147 respondents within the public sector in Finland. A multivariate linear regression analysis was done to examine how the ethical culture of organisations is related to organisational innovativeness.
Findings
A positive link was found in the ethical culture of an organisation and organisational innovativeness: ethical culture was important to behavioural, strategic and process innovativeness. Within the ethical culture of an organisation, the dimension of the congruency of management in particular had an important role in organisational innovativeness.
Research limitations/implications
The data were collected from the public sector, and therefore, future studies from the private sector organisations are needed. The results lend support to previous research arguments for the positive effect of an ethical organisational culture on organisational outcomes, particularly the organisational innovativeness described in this paper.
Practical implications
It is suggested that congruency of management, discussability and supportability are the organisational virtues which can most effectively enhance organisational innovativeness, specifically behavioural, strategic and process innovativeness in practice.
Originality/value
The research paper provides empirical evidence on the interrelation between the ethical culture of organisations and organisational innovativeness; evidence which is scarce in existing literature on organisational innovativeness. Thus, the paper helps fill this gap in the literature in the field.

Abstract
The cost of supporting multi‐million‐pound military systems and equipment during the “in‐service” phase is now often well in excess of two‐thirds of the total cost of ownership. The management approach used to predict, budget, validate and control overall support costs is known as integrated logistic support (ILS). Explains the military approach to “designing for support”, how this is integrated into the operational requirement, and the benefits which accrue. This leads to an analytical process known as logistic support analysis (LSA), which is integrated into a dynamic “supportability database” known as the logistic support analysis records (LSAR). It then becomes the definitive repository for information on all support activities, including provisioning and technical documentation, and continues “live” in the in‐service phase “supporting the design”. Under a US Department of Defense initiative, using electronic data interchange (EDI), known as CALS ‐ which was computer‐aided acquisition and logistics support, and has now been redefined as “continuous acquisition and life‐cycle support” ‐ the UK Ministry of Defence is currently fielding an Interim Defence Standard 00‐60, which it is promoting as a contender for a NATO and ISO Standard on ILS. The final edition will be a standard for contracting for ILS, provisioning, technical documentation and CALS using EDI.
