As urbanization accelerates worldwide, fostering inclusive and environmentally friendly cities becomes paramount. Pedestrian access plays a pivotal role in enhancing mobility, safety, and social connectivity. Additionally, promoting non-motorized mobility directly contributes to reducing carbon emissions and mitigating the ecological impact of urban expansion.

The safety and perception of safety on roads are crucial factors that affect the development of places. Various economic, social, and environmental factors influence the level of safety and sense of security on the roads. 

Collaborating with a professional team under the guidance of Professor Sarfaraz Hashemkhani Zolfani has been an honor for me. I appreciate all the contributors; Alireza Nemati and Hasan Mehtari Taheri.

Effects of extreme weather events and climate change on cities' livability

Climate change stands as a profound disruptor of contemporary human existence, reshaping the fundamental elements of meteorology across diverse temporal and spatial realms (Yalew et al., 2020). The global average temperature rise of 1.2 °C from 1900 to 2020 starkly illustrates the consequences of this phenomenon (Blunden & Boyer, 2021). This shift reverberates acutely at local and regional scales, particularly impacting urban centers, which find themselves on the frontline of this crisis (Perry et al., 2022). Cities grapple with a myriad of climate change manifestations, including sea level rise, storms, flood risks, heat waves, prolonged droughts, soil erosion, and land subsidence (Bazzi et al., 2021; Hsieh, 2021; Liang et al., 2020; Perry et al., 2022; Shi et al., 2022; Wardekker, 2021). These threats pose significant risks to urban life, encompassing natural disasters, environmental degradation, and public health concerns (Birkmann et al., 2015). For instance, they contribute to the reduction of quality of arable lands (Ma et al., 2020), the elimination of biodiversity and the decline of ecosystem services (Li et al., 2020), and the exacerbation of adverse effects on public health, living conditions, and socio-economic status (Hernández-Delgado, 2015; Markkanen & Anger-Kraavi, 2019).

Agri-food supply chain optimization through a decentralized production process in the olive oil industry

Carlos A. Monardes-Concha, Ph.D. - Assistant Professor at Universidad Católica del Norte, Chile.

We are glad to share one of our latest research published in the journal Computers and Industrial Engineering on the relevant area of olive oil production. Our paper proposes a novel multi-period, multi-product mathematical model that helps to solve a tactical/operational problem for agricultural communities and cooperatives, particularly in the growing olive oil industry. In this context, we model the connections between harvesting, transportation, and production operations in mobile olive mills (olive oil production plants), considering olive oil yields as a function of olive variety and the geographical location of agricultural fields.

This paper will be free until June 28, 2024.

A multi-objective optimization model for planning emergency shelters after a tsunami

Carlos A. Monardes-Concha, Ph.D. - Assistant Professor at Universidad Católica del Norte, Chile.

We are glad to share one of our latest research published in the journal Socio-Economic Planning Science on the critical topic of tsunami evacuation. Our paper introduces a multi-objective optimization model focused on vertical evacuation strategies, which involve seeking refuge in elevated structures rather than moving horizontally away from the coast. This approach helps alleviate congestion during evacuations and improves the efficiency of reaching safe zones.

This paper will be free until June 19, 2024.
