ABSTRACT
The COVID-19 pandemic that recently broke forth revealed the waning state of a considerable number of healthcare facilities, especially in unindustrialized territories. This is of great concern, and it has become pertinent to identify determinants of efficient maintenance management in developing countries. There is an inefficient maintenance management of hospital buildings due to a low level of maintenance documentation, which otherwise would have facilitated the adoption of digital twin (DT) technology. The existing maintenance management frameworks and models have not explored and evaluated maintenance documentation as an all-inclusive construct. Hence, this study was aimed at emphasizing the significance of maintenance documentation for its adoption as one of the main determinants of efficient maintenance management, with a view to attaining the DT maintenance management of hospital buildings in Nigeria. After a theoretical review on existing studies around documentation, the software documentation concept was used to conceptualise this observed gap in maintenance management models for public hospital buildings in developing countries. This critical review, which forms part of an ongoing study, asserts that maintenance documentation is a major construct for efficient maintenance management and a prerequisite for the adoption of DT in the management of healthcare constructed facilities in developing countries.
ABSTRACT
Attention to Smart Infrastructure (SI) has risen due to its advantages, including better access, increased quality of life, and simplified maintenance management. To develop SI, Public–Private Partnerships (PPPs) are identified as potentially beneficial procurement strategies, which boost capacities to manage risks by pooling diverse resources. However, the applicability of PPP in SI developments in developed countries is scarcely researched. This may be due to underestimating the other potential benefits from PPP, although developed countries may have their own funding to develop SI. Hence, this research aims to evaluate the significant factors influencing the success of PPP in SI projects in developed countries based on public-sector satisfaction (S1), private-sector satisfaction (S2), and end-user satisfaction (S3). A comprehensive literature review was followed by expert interviews and an international survey, focusing on developed countries. The Partial Least Squares Structural Equation Modeling (PLS-SEM) technique was applied to map the connections amongst the influencing factors and S1, S2, and S3. The results reveal that legal and political-related factors significantly impact on S2 and S3, while social barriers significantly impact on S1. The effect of the constructs and factors on S1, S2, and S3 along with their rankings are unveiled in this research paper, providing a sound basis to increase success levels and minimize shortfalls in PPP to boost SI developments in developed countries.

ABSTRACT
Featured ApplicationA novel methodology for project management applicable for self-protection plans for public buildings based on the best practices of technologies, systems, and methods.Self-protection plans are the fundamental tool established to prevent and control the risks that threaten people and assets. In turn, they are essential to provide an adequate response to possible emergency situations that may occur in public or private buildings, facilities, or events. In this context, current and future challenges advocate increasing the usefulness, versatility, and adaptability of self-protection plans. For this purpose, this paper aims to develop a conceptual model for the project management of self-protection plans with a lifecycle approach. The research provides results concerning guidelines, aspects, and potential regulations, technologies, tools, methodologies, and maintenance frameworks to be followed for any building in different project phases. The methodology followed has consisted of a process in stages, with literature review and a conceptual development to obtain an adaptable model to any public building. The adaptability of the framework relies on the definition of potential methods, information systems, and technologies that can support any phase during the Self-Protection Plan life cycle. Moreover, it was applied in a specific environment, such as in public buildings under the Spanish regulation using the most common tools and applications available. Results proved that although it is possible to make a base model applicable to any publicly owned building, there is an extensive and precise subsequent work of adaptation to specific cases in which the applicable legal framework makes this task challenging. Finally, the results obtained have allowed us to reflect on future research needs.
ABSTRACT
The Marine Forces Reserve (MARFORRES) comprises mainly citizen-soldiers who are required to operate across a broad spectrum of military operations at extended distances to support the Marine Corps missions. In recent years, the accountability and readiness scores for MARFORRES units have been declining. There have been previous studies endorsed by MARFORRES G-4 to develop a value model for the Supply and Maintenance Team (SMAT) inspection program through the analysis of a stakeholder derived objectives hierarchy. This thesis expands upon previous work by focusing on the following: 1) review of the existing value models to ensure they reflect the true value of the SMAT inspection program, 2) validation of the value models to articulate the contributions that the SMAT inspection program provides to MARFORRES mission, and 3) demonstration of the utility of value models for resourcing decisions in a budget-austere environment. MARFORRES can use the value models to revise its inspection policies to focus on value-driven inspection rather than mission-driven inspection. This will help to maximize the total value of SMAT inspection to the MARFORRES mission.
ABSTRACT
Featured ApplicationManagement model for air mobility and Service-oriented On-Demand Air Mobility. Modeling method for aircraft units between different vertiports within a given region considering mobility needs, capacity constraints, maintenance and charging needs. Exemplary application in a simulation model for a regional area of fifteen vertiports and their interconnection by means of electric aircraft units.Vertical mobility, as a commercial service, has been considered for scheduled volume and long-distance mobility services. To overcome its limits and increase its potential coverage, flexibility, and adaptability, centralized mobility hubs, similar to airports, will need to be constructed. Within this context, a customized and on-demand air mobility concept providing high flexibility in location combinations and time schedules could provide a solution for regional mobility needs. The aim of this research was to provide a generic framework for various mobility schemes as well as to design a holistic air mobility management concept for electric vertical mobility. A system dynamics simulation case study applied the conceptual model for an on-demand air mobility network of electric aircraft in a regional area with capacity constraints including vertiports, aircraft, charging, and parking stations. Therefore, bottlenecks and delays were quantified using a digital twin tool for customized scenarios. Simulation results showed that optimized maintenance management and the redistribution of aircraft units improved service indicators such as the number of customers served, and customer wait times as well as a reduction in the amount of time an aircraft spent on the ground. As a result, a digital twin air mobility network model with simulation capabilities may be a key factor for future implementation.
