Delivery Dates in Production: Reliable Planning for On-Time Delivery

How Proactive Collaborative Production Planning Enhances Schedule Adherence

Coordinating delivery dates is a major challenge for many manufacturing companies – especially when individualized »make-to-order products« make up a large proportion of overall production. Such products are not kept in stock, but are instead specifically manufactured to a customer's order once received. The aim is to promise a realistic delivery date – and to meet it reliably. This is where we provide support with mathematical approaches.

Production processes are subject to fluctuations: Requirements change, machines break down, personnel are not always available in a predictable manner and materials may be missing. In addition, product diversity is constantly increasing and production processes are becoming more complex – all of which make reliable scheduling difficult.

A robust forecasting and planning tool can help here. It provides a quick overview of capacity utilization and production capacities and thus supports the allocation of realistic delivery dates. These are as close as possible to the customer's desired date and can be met with high probability, even in the face of uncertainty. During ongoing operations, algorithms help to monitor deadlines, identify bottlenecks at an early stage, utilize buffers or flexibly schedule short-term requests.

Central Interface for All Units Involved

We develop customized planning and forecasting tools. A key success factor: all relevant data flows together in one central location – from sales and customer service to scheduling and production planning. Like this, the planning system serves as a central interface that provides all involved departments with up-to-date information.

Production Optimization Through Capacitive Planning

Our forecasting model uses a rough schedule of the key production steps: Mathematical optimization methods or tailored heuristic approaches are used to create a production plan that offers exactly the right level of detail – precise enough for a reliable deadline forecast, yet lean in terms of maintenance and quick to calculate.

This forward-looking planning not only benefits customers and sales, but also production itself: larger batches can be bundled economically, sequences can be scheduled optimally and stock orders can be placed more intentionally. This increases the overall throughput, reduces bottlenecks, allows suitable storage quantities to be kept in stock and can also have a positive effect on product quality.
