“…The construction industry has been heavily disrupted due to the spread of COVID-19, for instance, by delaying and halting construction projects under development before the pandemic began [ 10 ]. As online activities cannot replace construction activities on the construction sites, construction projects must continue to be developed in construction fields where construction workers are going to interact with each other risking getting COVID-19 [ 11 ]. Furthermore, as various cities and countries are starting to re-open from stay-at-home policies [ 12 ] and prepare plans for the financial response to boost local economies [ 13 ], construction projects appear to be an attractive alternative to do so by local authorities.…”

“…As the spread of COVID-19 has continued worldwide, research studies have started to report challenges that workers may face while performing their jobs during the pandemic context (e.g., [ 14 , 15 ]. Of note, a few studies have focused on the challenges that COVID-19 may have on construction workers in the current pandemic context [ 3 , 11 , 16 ]. For instance [ 11 ], proposed a model to study how the spread of COVID-19 among construction workers may impact the construction workforce’s planning during a project.…”

“…The model is not tractable analytically, and it has to be simulated on a computer, but the simulations are extremely fast and the model can account for several important non-linear feedback channels in the economy. Note that ABMs have also been used to model the spread of the epidemic itself, see [ 19 ].…”

V–, U–, L– or W–shaped economic recovery after Covid-19: Insights from an Agent Based Model

et al. 2021

We discuss the impact of a Covid-19–like shock on a simple model economy, described by the previously developed Mark-0 Agent-Based Model. We consider a mixed supply and demand shock, and show that depending on the shock parameters (amplitude and duration), our model economy can display V-shaped, U-shaped or W-shaped recoveries, and even an L-shaped output curve with permanent output loss. This is due to the economy getting trapped in a self-sustained “bad” state. We then discuss two policies that attempt to moderate the impact of the shock: giving easy credit to firms, and the so-called helicopter money, i.e. injecting new money into the households savings. We find that both policies are effective if strong enough. We highlight the potential danger of terminating these policies too early, although inflation is substantially increased by lax access to credit. Finally, we consider the impact of a second lockdown. While we only discuss a limited number of scenarios, our model is flexible and versatile enough to accommodate a wide variety of situations, thus serving as a useful exploratory tool for a qualitative, scenario-based understanding of post-Covid recovery. The corresponding code is available on-line.

“…‘ESPC’ may include companies providing utility services, delivery services, public transport, take-away services, and supermarkets. ‘ESPC’ may also include manufacturing companies producing essential supplies for both public and health care, such as productions for PPE, ventilators, and building temporary hospitals ( Araya, 2021 ). ‘NESPC’ are also considered as part of the control structure as their working policy relevant to COVID-19 significantly affects the behavior of employees, who form a large proportion of the public ( Ruiz-Frutos et al, 2021 ).…”

Analyzing National Responses to COVID-19 Pandemic using STPA

The unprecedented COVID-19 pandemic has affected most aspects of human life, including the ways in which organizations are operating. Minimizing the spread of coronavirus and its economic consequences, and creating a new and safe lifestyle has now become the common goals of governments all over the world. Although governments have responded to the COVID-19 pandemic by implementing various rules while interacting with relevant organizations to provide health service, vaccine research, and production of essential items, the complexities in the interactions between various stakeholders have proved to be challenging to have efficient and timely outputs. When different stakeholders (i.e. governments, organizations, and the public) are interacting with each other, a systems thinking process needs to be applied to capture the nuances of the interactions and the subsequent emergent behavior to effectively contribute to the system output (i.e. a safer way of life). This paper applied a system-thinking-inspired process called System Theoretic Process Analysis (STPA) to analyze the current response to the COVID-19 pandemic. The analysis treated various stakeholders as a part of the system, and it focused on the interactions among different stakeholders (i.e. functional blocks) within the system - i.e. ‘Government’, ‘Foreign Governments’, ‘Organizations’, and ‘General Public’, as well as the interactions with ‘W.H.O’. The STPA analysis found 236 potential Unsafe Control Actions (UCAs) (or unsafe interactions) among the stakeholder interactions, each of the UCAs was then further analyzed. In total 1440 causal factors of the UCAs were identified, and 2880 requirements were proposed to avoid such unsafe interactions.
