8.2 Facility Location Decisions

Facility location decisions are crucial in shaping supply chain performance. These choices impact costs, customer service, and operational efficiency. From geographic considerations to international factors, location affects everything from transportation expenses to inventory management.

Optimizing distribution networks involves quantitative methods and strategic thinking. Techniques like Center of Gravity and Load-Distance help find ideal locations. The choice between centralized and decentralized facilities involves trade-offs in economies of scale, flexibility, and market responsiveness.

1 of 3

• Proximity to suppliers, customers, and transportation infrastructure impacts long-term supply chain performance and profitability
• Labor availability, cost, and skill levels in potential locations affect operational efficiency and productivity
• Government regulations, taxes, and economic incentives influence the financial viability of facility locations (tax breaks, subsidies)
• Geographic and environmental factors shape operational constraints and opportunities (climate, natural resources, topography)
• Availability and cost of utilities, land, and other resources determine the feasibility of facility establishment (electricity rates, real estate prices)

International and Cultural Factors

• Political stability affects long-term operational security and risk management (government changes, policy shifts)
• Cultural considerations impact workforce management and local market acceptance (communication styles, work ethics)
• Language barriers influence operational efficiency and customer interactions (translation costs, potential misunderstandings)
• International trade agreements and regulations shape cross-border operations and logistics (tariffs, customs procedures)

Location Impact on Supply Chains

Cost and Performance Implications

• Transportation costs vary significantly based on facility location, affecting total logistics expenses (fuel costs, shipping rates)
• Inventory levels and associated carrying costs throughout the supply chain depend on facility positioning (storage requirements, stock turnover)
• Order fulfillment times and overall customer service levels correlate with proximity to markets (delivery speed, responsiveness)
• Procurement costs and supply chain responsiveness are influenced by distance from suppliers (lead times, bulk purchasing options)

Strategic and Operational Effects

• Supply chain flexibility and agility in responding to market changes depend on facility location (demand fluctuations, trend adaptability)
• Implementation of sustainable and environmentally friendly practices is affected by facility placement (renewable energy access, waste management options)
• Potential for economies of scale and scope in distribution operations varies with location choices (centralized vs. decentralized facilities)
• Risk management and business continuity planning are impacted by geographic diversification of facilities (natural disasters, geopolitical events)

Optimizing Distribution Networks

Quantitative Methods

• Center of Gravity method determines optimal location based on weighted average of existing facilities
  • Formula: $(X^*, Y^*) = (\frac{\sum_{i=1}^n w_i x_i}{\sum_{i=1}^n w_i}, \frac{\sum_{i=1}^n w_i y_i}{\sum_{i=1}^n w_i})$
  • Where $(X^*, Y^*)$ is the optimal location, $(x_i, y_i)$ are coordinates of existing facilities, and $w_i$ are weights
• Load-Distance technique minimizes total transportation costs considering distance and volume of goods moved
  • Objective: Minimize $\sum_{i=1}^n \sum_{j=1}^m d_{ij} v_{ij}$
  • Where $d_{ij}$ is the distance between points i and j, and $v_{ij}$ is the volume transported
• Mixed Integer Linear Programming models solve complex facility location problems with multiple constraints
  • Example constraint: $\sum_{j=1}^m x_{ij} = 1$ for all i, ensuring each customer is served by exactly one facility

Advanced Techniques and Tools

• P-median problem minimizes total weighted distance between demand points and facilities
  • Useful for determining optimal number and location of facilities to serve a set of demand points
• Capacitated and uncapacitated facility location models address scenarios based on facility capacity constraints
  • Capacitated models include constraints on maximum throughput or storage capacity of each facility
• Geographic Information Systems visualize and analyze spatial data for facility location decisions (demographic analysis, transportation network mapping)
• Simulation models evaluate performance of different facility location scenarios under various conditions (demand fluctuations, supply disruptions)

Centralized vs Decentralized Locations

Operational Trade-offs

• Centralized facilities often benefit from economies of scale but may increase transportation costs to distant customers
• Decentralized facilities can improve customer service levels and reduce delivery times but may increase overall facility and inventory costs
• Inventory risk pooling across different markets is more effective with centralized locations
• Centralized locations offer better control and standardization of processes, while decentralized locations allow for more customization to local markets

Strategic Implications

• Supply chain flexibility in responding to demand fluctuations varies between centralized and decentralized structures
• Tax implications and transfer pricing considerations differ between centralized and decentralized facility structures (international tax laws, profit allocation)
• Coordination complexity and information flow within the supply chain network are affected by the level of centralization
• Risk diversification and market penetration strategies are influenced by the choice between centralized and decentralized locations
