Automatic multi-stop route planning refers to the use of systems that automatically generate executable route configurations by simultaneously considering multiple delivery locations, vehicle constraints, time windows, and operational rules.
This technology has become a foundational capability across industries such as logistics and distribution, field service dispatch, sales visits, and on-site service operations.
At its core, this capability is an application of the Vehicle Routing Problem (VRP)—a classic optimization challenge focused on determining the most efficient routes for a fleet of vehicles under multiple constraints.
Over the past two decades, the rapid rise of various e-commerce models has driven significant growth in multi-stop delivery demand. However, many enterprises continue to rely on manual scheduling, leading to high planning costs, the need for large-scale fleet expansion, increased employee overtime, and limited scalability. In some markets, this has even contributed to structural challenges such as Japan’s so-called “2024 logistics crisis.”
As a result, automatic multi-stop route planning has increasingly emerged as a key concept in enterprise digital transformation.
Rising Demand Meets a Long-Term Technology Supply Gap
From a market perspective, demand for multi-stop route planning is far from ambiguous. Growing order volumes, expanding service coverage, and rising expectations for real-time responsiveness are pushing enterprises toward automated solutions. However, real-world implementations of automatic multi-stop route planning systems that successfully optimize routes at scale remain relatively rare.
The reason goes beyond the underperformance of most algorithms on the market—it lies largely in their inability to handle real-world operational scenarios.
Many tools can calculate theoretically shortest routes but overlook practical constraints such as driver and vehicle limitations or internal scheduling practices. The result is a solution that “looks smart on paper” but is ultimately unusable in practice.
Top Three Technology Barriers in Multi-Stop Route Optimization
The first bottleneck lies in the tension between global optimization and practical executability. While mathematical models aim to minimize cost or distance, what operations teams actually need are routes that are implementable on the ground and predictable in practice.
The second bottleneck is the highly fragmented set of constraints. Different industries have vastly different requirements for time windows, vehicle capacity, personnel skills, and service sequences, making generic models often unsuitable for long-term use.
The third bottleneck lies in computation time and system stability. Enterprises need automatic route planning to be completed within a limited timeframe, rather than sacrificing decision-making speed in pursuit of a theoretical optimal solution.
How Can We Achieve Practical, Deployable Automatic Multi-Stop Route Planning?
The most critical factor remains the choice of algorithm. Many solutions emphasize using a specific algorithm, but this approach is impractical. In the field of algorithms, the “no free lunch” theorem highlights that no single algorithm can effectively solve all types of delivery problems.
When designing our automatic multi-stop route planning system, we recognized that relying on a single algorithm is unrealistic. Instead, we deliberately incorporate multiple heuristic and metaheuristic approaches, dynamically selecting the optimal combination of algorithms based on the input parameters.
The next key factor is that the algorithms must be capable of accommodating a wide range of constraints. Achieving this requires long-term expertise in delivery optimization and careful collection of concerns and priorities from all stakeholders involved. After all, addressing real-world operational realities is critical to creating a deployable solution.
Next, we chose traditional CPUs as our computing platform rather than GPUs, primarily to ensure broader market accessibility. GPU computation can be roughly ten times more expensive per unit of processing time compared to CPUs. Until GPU costs become more affordable, we have focused on maximizing efficiency through algorithm design.
The system first generates an initial set of routes that align with practical operational logic, and then refines them according to the algorithmic rules. This approach positions automatic route planning as a starting point for operational decision-making, rather than the final verdict.
At the same time, the system supports multiple solution outputs and explainable results, allowing dispatchers to understand why routes are arranged in a certain way rather than passively accepting them. This transparency is essential for effective route optimization.
Future Prospects for Multi-Stop Route Optimization in Digital Transformation
We have observed that companies implementing automatic multi-stop route planning do not completely eliminate human involvement. Instead, humans focus on judgment and exception handling, with the ability to modify the system’s suggested routes. This means the algorithms do not make decisions for the business, but rather provide decision support.
The true value of automatic route planning lies in reducing scheduling barriers, shortening decision-making time, and accumulating operational knowledge that can be learned from. In the future, route planning systems will no longer be just computational tools—they will evolve into core operational modules with capabilities for preference learning, trust evaluation, and continuous optimization.
Automatic multi-stop route planning is not the end point, but a crucial starting point for enterprises on the path to scalable operations.
