What is logistics scheduling?
Definition
Logistics scheduling organizes production and activity management to maximize the efficiency of transport, storage and delivery operations. It is used to plan the use of resources, organize the flow of goods, set up order preparation and ensure that deliveries are made on time.
Scheduling takes into account various factors in the production chain, such as warehouse capacity, availability of means of transport, and deadlines imposed by customers and partners. The aim is to harmonize all logistics processes to optimize the overall flow, reduce waiting times and improve service quality.
The most commonly used scheduling methods
The Gantt chart
The Gantt chart is a highly visual representation of a project, divided into tasks. Each sequence is shown with its duration, time sequence and position in the hierarchy of events. In a logistics context, it can be used to visualize specific tasks in the supply chain, such as receiving and sorting goods, putting them into stock, preparing orders, and transporting them, including delivery times. It is used to monitor the progress of the various stages, identify delays, and allocate resources where they are needed.
The PERT method
PERT (Program Evaluation Review Technique) stands for "programme evaluation and review technique". It is a scheduling method based on probabilities, including estimates of the duration of each task. It also takes the form of a diagram, showing the dependency between tasks and the identification of a critical path. It differs from Gantt, which visualizes time planning. PERT takes into account the uncertainties associated with deadlines by considering three possible scenarios: optimistic, pessimistic and most probable. These assumptions give an idea of the earliest, latest and approximate lead times.
The CPM method
CPM (Critical Path Method) is a project management technique dating back to the 1950s. The critical path is defined as the longest sequence of tasks at the project execution level. It is the sequence that must be completed on time to meet the project deadline. If any task on the critical path falls behind schedule, the whole project suffers. The CPM method identifies each task belonging to the critical path, enabling the project duration to be calculated on the basis of the duration of each task.
Combining several scheduling methods
Combining several scheduling methods offers greater visibility over the life of the project. In logistics, for example, this would be the organization of flows. In addition to the above-mentioned methods, we can also talk about MRP to manage material resources, or JIT (just-in-time) used in warehousing. The use of several techniques enables us to better anticipate risks and be more responsive to unforeseen events.
The difference between planning and scheduling
Planning and scheduling are two very different processes. Planning establishes a project's overall objectives and broad guidelines, while scheduling precisely defines the allocation of resources over time. Planning takes a long-term view, while scheduling deals with immediate needs. In short, planning is about strategy, while scheduling is about operational tactics.
The benefits of logistics scheduling
Optimization of resources and storage capacities
Scheduling allocates available resources, such as personnel, handling equipment and order-picking consumables (stretch film, pallets, labels, etc.), with the aim of optimizing both internal flows and product distribution. By organizing flows in such a way as to avoid overloading or idle time, warehouse efficiency can be maximized. Rigorous inventory management makes all processes more fluid, taking into account both incoming and outgoing flows.
Lower logistics costs
Scheduling makes it possible to better anticipate transport and storage requirements, helping to reduce logistics costs. By adjusting flows and optimizing routes, companies can reduce the costs associated with delays, overstocking or unnecessary waiting times. What's more, by anticipating unforeseen events, you can reduce the need for costly emergency solutions.
Improved supplier/distributor relations
Scheduling helps strengthen coordination between the various players in the supply chain, notably suppliers and distributors. By optimizing lead times and ensuring better synchronization of deliveries, it becomes easier to build trusting relationships and secure lasting partnerships. For example, you'll no longer notify your carrier at the last minute, risking finding yourself without a solution or paying an exorbitant price. Instead, you show responsibility and foresight, demonstrating the seriousness of your organization.
Reducing waiting and delivery times
Scheduling also serves to minimize processing times, for both order preparation and delivery. Efficient flow management avoids unnecessary waiting times and improves customer satisfaction by guaranteeing shorter, more reliable delivery times.
The scheduler's role in the supply chain
Key responsibilities of a logistics scheduler
The logistics scheduler is responsible for organizing the flow of goods and anticipating resource requirements to meet demands as quickly as possible. Responsibilities include coordinating teams, managing priorities and adjusting schedules to meet unforeseen circumstances. This technician must also ensure that costs are optimized while meeting quality and service requirements.
Skills needed to be a good scheduler
Schedulers require technical skills in logistics, as well as organizational and interpersonal skills. Schedulers are generally managers, in charge of a team. They need to master scheduling tools, as well as being able to anticipate and solve problems quickly. The technician must also know how to communicate with all the players in the supply chain, both his team and partners, in order to make the most of collaboration and successfully complete the project.
Future prospects for logistics scheduling
Artificial intelligence for scheduling
With the emergence of artificial intelligence (AI) and machine learning (automatic machine learning from data), logistics scheduling is entering the modern era. These technologies enable processes to be automated and optimized faster and more accurately. AI analyzes data in real time and suggests adjustments to improve performance, reducing human error and increasing flexibility in the face of unforeseen circumstances.
The growing role of collaborative tools
Collaborative tools facilitate real-time coordination between each business line in the supply chain. We're talking here about interconnected platforms, online digital tools and connected objects (IoT). Interconnected platforms make it easier to share information instantly, and react quickly to changes. These tools enable better management of resources and improve companies' responsiveness to the unexpected.
Why does the TMS play a role in optimizing logistics scheduling?
Data centralization and process automation
TMSs (Transport Management Systems) centralize all operations relating to transport activities in the supply chain, from customer order to delivery. Having an overview of requests simplifies flow planning and enables resources to be allocated wisely. Thanks to TMSs, logistics managers can quickly adjust schedules according to unforeseen events (delays, incidents, cancellations, etc.). TMSs also avoid human errors associated with manual processes such as chartering, vehicle reservation, customs formalities, insurance, etc. They improve the fluidity of exchanges between the various parties involved in transport, such as suppliers, carriers or customers.
Greater visibility of the supply chain
One of the advantages of TMSs is that they offer a high degree of transparency over transport operations. If we take the example of our TMS, we can see that it provides an overview of each shipment, with continuous feedback. This makes it possible to identify bottlenecks and adapt scheduling accordingly. Thanks to instant alerts, you can anticipate delays and warn the consignee, react immediately to unforeseen events such as supply shortages or lack of carriers and, of course, optimize resources according to identified needs.
Cost reduction through better planning
Scheduling helps reduce costs. For example, kilometers can be minimized through precise route planning or shipment consolidation. It is also possible to reduce carriers' waiting times by better organizing incoming and outgoing flows, with adjusted routes or the assignment of time slots. Finally, TMS help optimize human and material resources by avoiding rushes or under-utilization.
KPI integration for continuous monitoring and improvement
TMS integrates performance indicators (KPIs) that enable scheduling to be analyzed and adjusted on an ongoing basis. Thanks to data analysis, companies can improve their productivity and results. These KPIs include
- Monitoring delivery times: to adjust schedules in the event of delays or incidents;
- Cost analysis: to identify optimization opportunities, such as transport costs or resource allocation;
- Optimize shipments by collecting accurate, actionable data.
Data security and traceability
Data management in TMS software enables complete traceability of transport operations. At Shiptify, our TMS provides clear visibility of every stage in the transport process. It also helps prevent errors or loss of information during exchanges with partners (customers, suppliers, carriers). In addition, it improves audit quality and ensures compliance with standards, by meeting legal and commercial requirements for traceability of actions.
Logistics scheduling remains a strategic lever for optimizing supply chain performance. Modern methods and advanced technological tools make it possible to manage resources efficiently, reduce costs, improve lead times and strengthen relationships with partners. In the age of digitalization, the introduction of AI and collaborative systems promises ever finer optimization of logistics processes.
