## 1 Introduction  
The strategic location of logistics centers (LCs) is crucial for ensuring the efficacy of supply chain activities in the ever-changing world of international commerce. Viewed from the perspective of logisticians navigating the complicated web of factors influencing the decision-making process, it explores the problematic realm of logistics center localization. In order for businesses to achieve their objectives of cost-effectiveness, sustainability, and agility, the strategic location of logistics facilities becomes crucial [1; 2]. An extensive infrastructure and economic development network is intended to link China and Pakistan's strategically located regions as part of the China-Pakistan Economic Corridor (CPEC), a major economic project. The corridor transverses several Pakistan areas and connects the deep-water port of Gwadar with the western Chinese city of Kashgar [3]. Because it impacts the choice of hubs and ports in Pakistan, the CPEC's geolocation is crucial. The hub of the CPEC is Gwadar, which is situated in the province of Baluchistan in the southwest. Because of its advantageous position on the Arabian Sea, it is an essential port for trade and business, giving China a quicker and safer path for its imports and exports. Another port in Balochistan, Ormara, is crucial to the CPEC because it offers a different path for trade and improves communication throughout the area [4]. Karachi, Pakistan's main metropolis and commercial center, handles a sizable amount of the nation's trade and is a key port for the CPEC. Its well-developed infrastructure and proximity to the Arabian Sea make it a crucial node within the corridor. Balochistan port town, Pasicontributes to the adequate flow of commodities and services by strengthening the CPEC's maritime connectivity [5]. The hubs of Gilgit, Peshawar, Karachi, and Quetta are positioned efficiently along the CPEC route in addition to the ports. These hubs are crucial locations for the movement and distribution of goods and for the growth of economic and industrial zones. As a vital hub for the movement of products into and out of the corridor, Tianjin, a significant port city in northeastern China, plays a pivotal role in the Chinese side of the CPEC [6; 7]. Situated in the Xinjiang area of China, Kashgar serves as a crucial hub for the China-Pakistan Economic Corridor (CPEC), linking the corridor to the broader web of Chinese trade routes and infrastructure. For the corridor to operate effectively and efficiently, there must be a relationship between the CPEC's geolocation and the ports and hubs chosen in China and Pakistan [8]. It promotes regional integration and economic growth while guaranteeing smooth connectivity and trade between the two nations [9]. LC selection in the CPEC is different from other scenarios. CPEC's strategic location, transport logistics, and international cooperation with China and Pakistan make geopolitical factors more critical [10]. Location strategy must consider transportation hubs, weather patterns, and the intricate geopolitical landscape, including diplomatic interactions, political stability, and international agreements. Infrastructure has become increasingly essential for domestic and cross-border networks [11; 12]. The market proximity is necessary to understand Chinese and Pakistani consumers and economic conditions. Regulations span national borders, requiring careful compliance with local, international, and trade agreements. Sustainability must align with the global commitment to green supply chains and emphasize sustainable corporate practices in CPEC's cross-national context [13]. Locating LC involves predicting and adjusting to dynamic changes in market demands, consumer behavior, and geopolitical issues, which may affect selected locations' long-term viability and effectiveness. This research, which focuses on the CPEC, uses an FD TOPSIS approach to determine the best sites for LC in China and Pakistan.
