Facility location and network optimization are crucial for global supply chains. Companies must carefully choose where to place facilities, considering factors like costs, risks, and customer service. These decisions shape the entire distribution network's performance and resilience.
Optimizing global supply chains involves complex trade-offs. Mathematical models help balance , inventory levels, and customer service. Companies must design networks that are both efficient and resilient, adapting to changing market conditions and potential disruptions.

involves determining the optimal placement of facilities within a supply chain network to minimize costs and maximize efficiency
Key factors considered include:
Transportation costs
Taxes and duties
and customers
The global context introduces additional complexities:
Varying transportation modes and costs
Trade regulations
Currency fluctuations
Political risks
Cultural differences that impact facility location decisions
Techniques and Strategies
Techniques for facility location analysis include:
Mathematical optimization models
These methods consider quantitative and qualitative factors to evaluate potential locations
Facility location decisions have long-term strategic implications for a company's global supply chain performance:
Responsiveness
Flexibility
Competitiveness
Global facility location strategies may involve:
Offshoring production
Nearshoring production
Reshoring production based on changing market conditions, costs, and risks
Optimization of Global Supply Chains
Mathematical Models and Algorithms
Mathematical optimization models, such as (MILP), are used to determine the optimal number, location, and capacity of facilities in a global supply chain network
These models consider various constraints:
Facility capacities
Product flows
Transportation modes
requirements
The objective is to minimize total supply chain costs while meeting demand
Network are used to solve specific subproblems within the larger facility location problem:
Shortest path
Minimum spanning tree
Maximum flow
Heuristics and Sensitivity Analysis
Heuristic and , such as and , are used to find near-optimal solutions for large-scale, complex global supply chain networks when exact optimization methods are computationally infeasible
is conducted to evaluate the robustness of the optimal solution under different scenarios:
Changes in demand
Changes in costs
Disruptions
This analysis informs decision-making and helps identify the most critical factors affecting the global supply chain network
Trade-offs in Global Facility Location
Transportation Costs and Inventory Levels
Transportation costs are a significant factor in global facility location decisions, as they impact the of products
Trade-offs exist between centralized and decentralized distribution strategies:
Centralization often leads to lower inventory costs but higher transportation costs
Decentralization can reduce transportation costs but may increase inventory costs
Inventory levels must be carefully managed in global supply chains to balance the cost of holding inventory with the risk of stockouts and lost sales
Facility location decisions affect inventory levels by determining the number and placement of stocking points
Customer Service and Total Cost Optimization
Customer service levels, measured by metrics such as order fill rates and delivery lead times, are influenced by facility location decisions
Locating facilities closer to customers can improve responsiveness but may increase costs
The total cost of the global supply chain, including transportation, inventory, and facility costs, must be optimized while meeting customer service level targets
, such as consolidating inventory in fewer locations (e.g., ), can be used to reduce overall inventory levels and costs while maintaining customer service levels
Designing Resilient Global Distribution Networks
Efficiency and Resilience
An efficient global distribution network minimizes total supply chain costs while meeting customer service level requirements
This involves optimizing the number, location, and capacity of and transportation routes
A resilient global distribution network is able to withstand and recover from disruptions:
Risk assessment and mitigation strategies are used to manage these risks:
Scenario planning to prepare for potential disruptions
Insurance to protect against financial losses
Sustainability considerations are increasingly important in global distribution network design:
Carbon emissions from transportation and facilities
Energy consumption in warehouses and distribution centers
Waste reduction and recycling efforts
Strategies for improving sustainability include:
Optimizing transportation modes (rail, sea, road)
Using eco-friendly packaging materials
Collaborating with suppliers and customers on sustainability initiatives
Technology, such as real-time tracking and visibility systems, can be used to improve the efficiency and resilience of global distribution networks by enabling better decision-making and faster response to disruptions
