Abstract: Material efficiency has become a pressing concern in modern building design, driven by the need to reduce resource consumption and lower environmental impacts. This systematic review explores how advanced structural modeling contributes to the development of load-optimized, materially efficient structures. By focusing on computational techniques-including finite element analysis, topology optimization, parametric modeling, and AI-assisted design-the review underscores how these methods enhance the alignment between structural form and internal force distribution. Recent developments in geometry-informed design strategies, form-finding methods, and performance-based workflows are examined for their capacity to reduce material usage without compromising structural integrity or performance. Applications in shell structures, high-rise buildings, and complex architectural forms are presented as case studies, demonstrating how computational design approaches can deliver practical and measurable benefits in real-world contexts. At the same time, the review acknowledges persistent challenges such as computational accuracy, scalability of modeling methods, and the integration of engineering analysis with creative architectural processes. These issues highlight the importance of interdisciplinary collaboration and continuous refinement of digital tools. The findings suggest that structural mechanics can serve not only as a means of evaluation but also as a generative framework for design-guiding the creation of efficient, sustainable structures from the early conceptual stage. By bridging structural analysis and material responsibility, this study contributes to a broader conversation about how digital innovation and engineering principles can support the transition toward a more sustainable and resource-conscious built environment.

Abstract: Intersections are one of the most crucial parts of urban transportation systems since they actively contribute to developing strategies to reduce traffic congestion. One of the major issues that nations around the world face is traffic congestion on roads and intersections. More than 90% of intersections on high-speed roads in developing countries have poor turning space, compared to 64% in developed countries. This study evaluates the performance of major intersections for improving traffic safety and efficiency in Shashemene Town. The objective of this study was to assess current traffic flow patterns, evaluate the effectiveness of existing traffic control measures, and propose potential improvements to enhance safety and efficiency at the selected major intersections. The scope of the study was limited to the three major intersections in Shashemene Town, such as Awasho Roundabout, Abosto Intersection, and Semaniya-Andi Intersection, with a focus on understanding the challenges faced in this urban context. The data were collected using a combination of traffic volume counts and user surveys during peak traffic hours. The SIDRA Intersection Version 8.0 software was employed to evaluate key performance indicators, including travel time, delay, travel speed, LOS, and V/C ratio. The analysis revealed significant congestion at the Awasho Roundabout, with an average travel speed of 35 Kph, a control delay of 24.1 s/veh, LOS C, and a V/C ratio of 0.81. The Abosto Intersection showed moderate delays with a delay of 34.1 s/veh, LOS D, and a V/C ratio of 0.98, while the Semaniya-Andi Intersection performed the best with a delay of 12.8 s/veh, LOS B, and a V/C ratio of 0.64. The findings indicate that while the Semaniya-Andi Intersection operates within acceptable performance levels, the Awasho Roundabout is severely congested, necessitating immediate interventions. To guide drivers, install clear and visible road markings, and ensure pedestrian safety. Installing well-marked pedestrian crossings improves traffic safety and efficiency of the roundabout as a short-term intervention. As a long-term improvement, redesigning the roundabout to accommodate higher traffic volumes and improve flow.

Abstract: Building site of the light industry plant should be selected with full consideration of land, electricity, water, transport, raw material supply and environment protection condition of the corresponding area, otherwise it may have a negative effect on the cost of product. Therefore, the optimal selection of building site is very important to the economic revival of enterprise. We have considered a plant building site selection with AHP (Analytic Hierarchy Process) and Geographic Information System (GIS) in NSDL environment. NSDL (Net-oriented System Language) is a complex system modeling tool, which has been developed by combining the advantages of Petri Net with Object-Oriented Programming Language VB (Visual Basic). AHP is a comparative assessment method using human sense, which models the influence of the criteria associated with decision making into a hierarchical structure and allow to choose the best among alternatives to be selected. AHP is widely used in various fields of economy, military, society, management, education, medicine, etc. Also, this method can deal with qualitative or quantitative data. Unlike the other AHP tools, the hierarchical structure models were made by Petri net diagram of NSDL, provides the automatic information link with the AHP module to improve the intuition, flexibility and convenience of decision making tools. In addition, using the object-oriented VB script language of NSDL with powerful integration ability, ArcGIS were combined to perform geographic information analysis to determine the optimal plant building site.
