Optimization of transport modes in tactical distribution planning
Between cost, speed and sustainability - data-based decisions for complex supply networks
Fast or cheap? Direct or consolidated? Anyone making decisions about means of transportation in distribution logistics is often faced with precisely these conflicting objectives. The choice between rail or air freight, FTL (full truck load) or LTL (less-than-truckload) is not a purely operational question - it has a significant impact on a company's profitability, service quality and ecological balance sheet.
But how can the optimum mode be determined in a complex network with hundreds of routes and changing requirements? The answer lies in mathematical optimization - an approach that makes it possible to make well-founded decisions based on data, scenarios and conflicting objectives.
The reality of distribution planning: conflicting goals and uncertainty
Cost, service level and sustainability in conflict
The reality in many companies shows that the choice of transportation mode is often made under uncertainty and time pressure. Planners are faced with the challenge of reconciling contradictory objectives. On the one hand, transportation costs should be reduced, but on the other hand, service levels must not be undercut. At the same time, there is growing pressure to achieve ecological goals and reduce CO₂ emissions. These requirements are often in direct conflict with each other. For example, although the use of rail transport can significantly reduce emissions, it can result in longer transit times and therefore jeopardize the ability to meet delivery deadlines.
Lack of transparency in carrier performance data
In addition, many companies do not take information about the actual performance of carriers - such as punctuality rates, damage rates or average delays - into account in their planning. This often leaves untapped efficiency potential that is not visible at first glance. A concrete example: a carrier with a punctuality rate of 89 % may incur eight percent higher costs than the cheapest provider, but its reliability can make a decisive contribution to meeting service levels - especially for time-critical deliveries. Such trade-offs can only be made if the corresponding performance data is systematically recorded and integrated into the planning.
Complexity of multi-level networks as an additional hurdle
The complexity is further increased by the structure of modern distribution networks. In multi-level systems with central hubs, regional distribution centers and thousands of customers, there are countless possible transport routes. Manually evaluating all these options is practically impossible. Specialized software solutions are needed that are capable of mastering this complexity and at the same time mathematically mapping conflicting objectives.
Mathematical optimization as the methodological core
More and more companies are turning to mathematical optimization to select the optimal transport mode. This is a method that calculates the best possible solution for a complex decision problem on the basis of defined goals, restrictions and data. In the context of distribution planning, this means that the most efficient transport mode is determined for each route in the network - taking into account costs, time, emissions and service requirements.
Optimization of transport mode selection with OPTANO
Data integration as the basis for reliable decisions
A central element for reliable decisions is the integration of all relevant data sources - and this is precisely where OPTANO comes in. The planning software makes it possible to combine traditional transportation costs for FTL, LTL, rail and air freight with qualitative information on the performance of individual carriers. Historical punctuality data, damage rates, service level fulfilment and environmental indicators such as CO₂ emissions per tonne-kilometre are recorded in OPTANO in a structured manner and included in the optimization process. This creates a sound basis for decision-making that takes both economic and ecological objectives into account.
Scenario comparison creates transparency about conflicting objectives
Another key advantage of mathematical optimization is the ability to systematically compare different scenarios. With planning software such as OPTANO, companies can examine how the switch from truck to rail will affect costs, emissions and delivery times. Changes such as new sustainability targets or carrier failures can also be simulated. These scenarios make conflicting objectives visible and provide a valuable basis for decision-making. They enable strategies to be designed proactively rather than reactively.
Mixed-mode strategies as an efficiency lever
The use of mixed-mode strategies, in which different transport modes are intelligently combined in order to make optimum use of their respective advantages, is particularly effective. A typical example is the combination of rail and LTL: large quantities of goods are first transported by rail to a regional hub, from where they are distributed by LTL. This strategy makes it possible to combine the cost benefits and environmental friendliness of rail transportation with the flexibility of truck transport. With OPTANO, such strategies can be used specifically where they bring the greatest benefit - for example on high-volume routes with predictable time windows. The software automatically calculates the best mode combinations and shows how these affect costs, emissions and service levels. The choice of mode thus becomes a strategic lever for sustainable and economical logistics.
Measurable effects on costs, emissions and service level
The use of mathematical optimization in transport mode selection has been proven to lead to significant improvements: Transport costs can be reduced by an average of 8-15 %, CO₂ emissions by 10-20 % - especially through the targeted use of rail transport and intermodal solutions. OPTANO uses mathematical models to visualize this potential and translate it into concrete measures.
Service quality also benefits: Taking carrier performance data into account helps in the selection of reliable partners. This improves on-time delivery and service levels by 2-5 % - often at no extra cost. At the same time, OPTANO significantly shortens the planning time: instead of weeks of manual evaluations, the solution enables well-founded decisions to be made within a few hours. This means that optimization is not just theoretical, but effective in practice.

Optimization makes conflicting goals manageable
The choice of transport mode is not an operational detail, but a strategic lever with far-reaching effects. Companies that make their choice of mode based on data and in an optimized manner gain a clear competitive advantage. Not only can they improve their cost structure, they can also achieve ecological goals and increase service quality at the same time.
Mathematical optimization offers the necessary methodology to make complex conflicting objectives transparent and enable well-founded decisions. Through the integration of carrier performance data, the simulation of different scenarios and the targeted use of mixed-mode strategies, distribution planning becomes not only more efficient, but also more resilient and sustainable. At a time when supply chains are under constant pressure to adapt, this capability is crucial for long-term success.
