“…A literature study showed that AHP is a valuable technique for weighting the sustainability indicators as (a) AHP has the properties of a hierarchical composition, which is allied with the structures of very frameworks of sustainability and makes up the process simple to understand for stakeholders; (b) it stipulates a constant corroboration operation; (c) AHP is flexible and easy; (d) it can be applied with both quantitative and qualitative data [60][61][62][63]. Furthermore, the AHP method is recognized as efficient and broadly applied by numerous studies for various sustainability-associated task solutions [49,60,61,[64][65][66][67][68][69].…”

Infrastructure projects require lifecycle-based assessment, considering the interests of multiple stakeholders concerning the three pillars of sustainability. There has been a heightened curiosity in employing sustainability indicators for gauging the impacts of developmental projects. Even though the literature is abundant on sustainability assessment methods, there is no proper one for the assessment of urban infrastructure projects in the context of Gulf states. Thus, our research intends to fill in this research gap and recommend an incorporated, hierarchically coordinated approach of sustainability indicators to be employed for the sustainability assessment of urban infrastructure development projects. This aim is achieved through a questionnaire survey, by identifying the sustainability indicators related to the infrastructure projects for the cities, in the context of Gulf states. The survey uses the criteria; “Important”, “Practicality”, “Reliability”, and “Relevance” to assess those indicators. Based on expert opinions, the weights of the indicators are approximated through the analytical hierarchy process (AHP) method. Thus, the study proposes an innovative hierarchically defined structure of sustainability indicators fitting for the Gulf context. Further, it informs urban planners and policymakers, particularly in the Gulf states, about the shift in the direction of sustainability of urban infrastructure systems.

“…One of the most important and difficult tasks faced by model developers is model validation and the validation process [51]. This paper refers to the research methods of Ransikarbum et al and, combined with the research on integration by Chanthakhot [52] and Wattanasaeng [53], verifies the evacuation model by comparing and fitting the simulation results of different evacuation simulation software in different evacuation numbers. Integration aspects related to simulation research are essential.…”

During a fire evacuation, long lateral evacuation distances, large crowds waiting for evacuation at the same level, and easily panicked populations are common. This research aimed to look into the large-scale evacuation behavior of urban underground complexes with limited evacuation and egress during a fire. A simplified model for large-scale group evacuation of urban subsurface complexes was constructed using system dynamics theory. The Vensim software was used for quantitative simulation. The model could represent the typical phenomenon of group evacuation behaviors, such as quick or slow, under seven operating situations with total initial numbers of 350, 400, 450, 500, 1000, 2000, and 4000. The results of an analysis of critical affecting factors show “total initial number” and “panic state” during a large-scale group evacuation: a large beginning population will result in a rapid reduction in system evacuation capability, delaying the completion of the evacuation process significantly; meanwhile, if the level of panic is deficient, the system’s evacuation efficiency will remain low for an extended period, making it difficult to evacuate trapped persons promptly. According to the findings, the developed system dynamics model, which combines the advantages of a continuous model with the advantages of a discrete model, is very accurate. At the same time, we should emphasize the importance of the evacuation guide and reinforce the fire education and behavior drills for the building’s workers. This research presents a simplified model for the evacuation of large groups of people from metropolitan underground complexes. Furthermore, the findings may give theoretical support for the development of rules and safety management practices.

“…The crucial aspect is determining the optimal method for a specific issue, in light of the wide variety of techniques available, such as AHP [42,43], ÉLimination Et Choix Traduisant la RÉalité (ELECTRE) [44], the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) [44,45], and PROMETHEE [46]. In the exploration of the criteria for assigning weights to computational methods, the AHP stands out as the primary technique for establishing these weights through pairwise comparisons.…”

Sustainable manufacturing technologies are the new challenge faced by enterprises, industries, and researchers. The development of a sustainability-based assessment method considering the environmental and economic impacts is crucial to realize viable manufacturing. However, few studies have addressed environmental economics and social flows using a common perspective. Mechanical machining is one of the most-used manufacturing techniques. The overall ecological, economic, and social footprint requires accurate and effective estimation and optimization. Several studies have addressed this issue by examining the entire process of machining, but sustainability flows for machining parameters and toolpaths have remained relatively unexplored. The lack of systematic assistance tools bridging the gap between decision-maker preferences and the three sustainability pillars—economic, social, and environmental—has impeded the widespread adoption of sustainable machining practices. To this end, this paper proposes an integrated approach to the decision-making problem that combines the Analytical Hierarchy Process (AHP) with the Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) for selecting a sustainable machining strategy. The sustainability criteria are driven by manufacturing process parameters commonly employed and regulated during the manufacturing phase. This includes toolpath strategies as a qualitative input factor and manufacturing parameters such as cutting speed, feed rate, depth of cut, and stepover as quantitative input factors, affirming the practical applicability of the method in industrial contexts. New fundamental methods are also presented for selecting the most efficient machining parameters and toolpaths according to the weights assigned to each ecological, social, and economic footprint by the decision-maker (the manufacturer or production manager). In this way, sustainable machining strategies in the manufacturing industry will be strengthened in integrity. In a case study of part-end milling, both manufacturing parameters and toolpath strategies are considered to establish sustainable feature-based machining decisions.
