### Selection Criteria for Logistics Locations
#### 2.2.5 Proximity to Suppliers  
This is a crucial factor, especially for manufacturing and distribution firms, regarding the suppliers' locations and supply chains. This shortens lead times and lowers the cost of incoming transportation for locating raw materials and components [30]. The literature highlights the significance of applying decision support techniques like AHP and MCDM to handle the intricate allocation problems of logistics location selection. Several techniques highlighted by the authors are displayed in Table 1. \begin{table}

Table 1: Summary of numerous investigations and their importance. For selecting a logistics location, it is also essential to consider several aspects, such as those connected to cost, infrastructure, demand, and environmental sustainability. The research determined the danger of landslides along the CPEC [38]. The authors evaluated the risks connected to landslides in the area and offered insightful recommendations for lowering the probability of disasters. The results enhanced the understanding of geological risks within the framework of the economic corridor. The author focused on freight trucks operating along the CPEC's altitude-dependent gaseous emissions [39]. They investigated the effects of truck emissions on the environment at various elevations. They provided essential insights into the variations in gaseous pollutants emitted by freight trucks. The study investigated the risk and vulnerability of the CPEC to natural hazards [40]. They evaluated the possible natural disasters that could affect the CPEC's socioeconomic and physical elements. They intended to provide insightful information on effective resilience and risk management strategies in the important economic corridor. The studies employed a systematic framework for evaluating possible locations to improve decision-making and planning efficiency for logistics in the Thrace region. The input parameter and assumption sensitivity can be limited in the study. Sustainability considerations were researched before deciding on a location for a logistics center [41]. The authors suggested improving decision-making using an ordered weighted average (OWA) operator and a similarity based TOPSIS technique. The outcomes provided insightful information for logistics center location optimization and demonstrated that the strategy considers sustainability concerns.
