Nowadays, the concepts of viability and sustainability in project scheduling by considering the complexity of networks have become increasingly important in recent research studies, especially during complex situations. In addition, Viable and Antifragile Project Management (VAPM) applies antifragility, resiliency, sustainability, and agility in different phases of planning and scheduling for complex networks and systems. Attention to resiliency is also essential because disruption and fluctuations force planning, scheduling, and the consequent negative impacts are unknown to many project managers. Furthermore, planning, monitoring, and controlling project delivery and process support are highly dependent on the life-cycles economic, environmental, and social aspects.

In addition to resiliency and agility, paying more attention to sustainable development is inevitable during project management (PM). Sustainable development mainly comprises of environmental impact, energy consumption, and social impact. Carbon emissions, carbon trading, and waste management are practical solutions to decrease the environmental impact. Using renewable and clean energy is also one of the strategies to apply viability in project management. Meanwhile, implementing novel technologies, such as blockchain, Internet-of-Things (IoT), and Artificial Intelligence (AI), can assist and enable the transition to running lean project management as agility tools and decrease the complexity network. However, these tools require appropriate modeling to demonstrate the superiority of the latest technologies. Therefore, we need to use VAPM to improve the complexity of the network and move to antifragility, resilience, sustainability, and agility, and use novel technologies in different phases of projects.

This Special Issue aims to investigate recent advances in viability and sustainability in project scheduling and management. Thus, we seek contributions from authors presenting novel models toward ensuring resiliency, sustainability, and agility in PM. This Special Issue invites researchers and scholars to propose methods based on mathematical modeling and AI-based approaches to improve the current situation and fulfill requirements. We welcome original research and review articles.
