Formulating Logistical Strategyto Finalize Logistical Strategy It Is

To finalize logistical strategy, it is necessary to evaluate the relationships between alternative customer service levels and associated costs. While substantial difficulties exist in measuring revenue, the comparative evaluation of marginal service performance and related costs offers a way to approximate an ideal logistical system design. The general approach consists of four steps: (1) determining a least-total-cost network, (2) measuring service availability and capability associated with the least-total-cost system design, (3) conducting sensitivity analysis related to incremental service and cost directly with revenue generation, and (4) finalizing the plan.

Cost minimization is a core principle in logistical strategy development. An analogy can be drawn with a physical map that illustrates land surface features such as elevations and depressions; similarly, an economic map highlights cost differentials across logistics networks. Peak costs for labor and essential services often occur in large metropolitan areas; however, due to demand concentration, the overall logistics cost—especially transportation and inventory consolidation benefits—can be minimized within these urban centers. A least total cost strategy seeks a network with the lowest fixed and variable costs, emphasizing cost-to-cost trade-offs as the main driver of system design.

The concept of total least cost assumes that trade-offs between transportation and inventory costs dictate the optimal configuration, balancing expenditure across the network. For example, Figure 12.6 (not shown here) illustrates how different geographic and logistical considerations influence the cost landscape and the resultant system design. Establishing a least-cost network requires analyzing various configurations to identify the one that minimizes total costs, including transportation, warehousing, and inventory holding.

The level of customer service associated with this least-cost design is typically described by the threshold service level. This threshold reflects the service capability built into the system, determined by safety stock policies and warehouse proximity to customers. The threshold service level is crucial because it influences inventory availability and delivery performance. To establish this level, companies often begin with assumptions based on current operations—such as existing order processing capabilities, warehouse throughput times, and transportation delivery schedules—and then evaluate potential improvements.

For instance, a common starting point involves setting safety stock levels that aim for a specific fill rate, often drawn from industry standards. A safety stock availability of approximately 97.75 percent suggests that about 98 out of 100 items ordered will be delivered as specified, ensuring a high service quality while controlling inventory costs. Under these assumptions, customers are assigned to shipment locations based on the least total cost, considering all logistical expenses.

In multi-product scenarios, choosing service territories for each warehouse depends heavily on the product mix and customer consolidation requirements. Since costs vary geographically, the service areas are irregular and dynamic. As illustrated in typical models, service territories are delineated by lines of equal total cost—these include all logistical expenses, such as warehousing, handling, and transportation. For example, in a regional setting with three warehouses labeled X, Y, and Z, the boundary lines between service areas are established where the total associated costs are equal for servicing customers from adjacent warehouses.

The cost contours around each facility—represented as lines at regular intervals (e.g., $1.50, $2.50, $3.50)—demonstrate how total logistics costs fluctuate geographically. Customers within each region can be serviced at costs below these lines, indicating their position within optimal service zones. These boundaries are determined by the lowest total cost of service, yet they do not account directly for delivery time variations, which may influence customer satisfaction and lead times. Consequently, balancing cost-efficiency with customer responsiveness remains a fundamental aspect of logistical planning.

Developing a comprehensive logistical strategy is fundamental to optimizing supply chain performance, balancing cost efficiency with customer service quality. This process involves meticulously evaluating and designing a network that minimizes total logistics costs while maintaining acceptable service levels. The primary goal is to determine a least-cost network, measure its service capability, perform sensitivity analysis, and implement the most effective plan.

At the core of logistical planning is cost minimization, which requires a detailed understanding of geographic cost differentials. Urban centers typically exhibit peak costs for labor and utilities; however, their demand density enables transportation and inventory economies of scale. Consequently, integrating transportation and inventory consolidation benefits often results in net cost reductions despite higher local expenses. Logistical systems adopting a least total cost approach are driven by trade-offs—optimizing fixed and variable costs across the network to achieve operational efficiency.

The total least-cost design involves comprehensive geographic and operational analysis, often visualized through cost contour maps. These maps pinpoint the lowest combined costs for servicing customers, considering transportation, warehousing, and inventory costs. For example, hypothetical models often depict transportation costs through lines or contours, illustrating how logistical expenses fluctuate geographically. Establishing these boundaries allows managers to define service territories that optimize cost efficiency while meeting customer demand.

A critical component of the logistical strategy is setting the threshold service level, which signifies the system’s capability to meet customer expectations. Establishing this threshold begins with assumptions based on existing performance and industry standards, such as desired safety stock levels and responsiveness. For instance, safety stock policies often target a 97.75% fill rate, indicating that most customer orders will be fulfilled as promised. These assumptions serve as the baseline from which to evaluate potential improvements in service levels and operational efficiency.

The assignment of service territories in multi-product environments hinges on product profiles and customer consolidation needs. Since logistical costs are geographically sensitive, service areas become irregular and are defined by the total cost to serve each region. The boundary lines between service zones—determined by equal total costs—delineate the most economical coverage for warehouses. These lines are crucial for designing efficient networks that balance transportation and inventory costs while considering additional factors like delivery time and customer satisfaction.

Ultimately, a successful logistical strategy requires integrating cost analysis, service capability assessments, sensitivity testing, and continuous improvement. By applying data-driven insights to network design, companies can achieve an optimal balance of cost and service quality. This balanced approach leads to resilient, scalable, and customer-responsive logistics systems capable of adapting to changing market dynamics and operational constraints.
