Assembly and production planning
Assembly and production planning: Designing efficiency, ensuring competitiveness
Ensuring sustainable competitiveness today means more than just excellent quality and innovative strength. The focus is on efficient, flexible and digitally supported processes in production and assembly. Whether designing new production lines, optimizing existing systems or integrating modern technologies, holistic production and assembly planning is the key success factor for productivity, cost optimization and scalability.
Production planning lays the strategic foundation by precisely defining processes for the manufacture of parts and components. Building on this, assembly planning ensures that these elements are brought together efficiently, ergonomically and error-free to create the finished product. Only through the interaction of both disciplines can flexibility, throughput times and the use of resources be optimally controlled.
At Rothbaum Consulting, we don’t just redesign these processes – we think in terms of end-to-end value creation systems, create transparency along the entire production chain and develop solutions that are sustainable in the long term. Whether it’s a greenfield project or brownfield optimization: we provide you with practical support in the planning, digitalization and continuous improvement of your manufacturing and assembly processes.

Production strategies and concepts
Individually tailored production concepts for lean, scalable processes
As a specialized operations consultancy, we support companies in developing and implementing the optimal production strategy. Together, we analyze whether make-to-order, make-to-stock or assemble-to-order is best suited to the products, market requirements and volumes – always with an eye on efficiency, flexibility and costs.
We analyze and identify the most suitable production system: whether it’s continuous flow production for high volumes, flexible workshop production for a wide range of variants or hybrid matrix production for complex product structures. We design the systems in such a way that they remain scalable and adaptable.
One focus of our advice on assembly planning and production planning is the introduction of lean production concepts to reduce waste and streamline processes. This is complemented by the implementation of modularization and platform strategies to make product variants manageable and speed up production processes.
We also promote close cooperation with product development in order to design products for assembly right from the start and thus make production processes more efficient.
We support you in making your production future-proof, efficient and competitive.

Line and assembly planning
Efficiency starts with the right layout – we redesign production

In production and assembly planning, we design holistic, future-proof manufacturing systems – efficient, flexible and scalable. We analyze existing structures, uncover weak points and develop new production environments – from intelligent layout planning and lean material flows to precise assembly cycles.
We create an optimal machine layout, design lean processes and minimize waste along the entire value chain. Our customized assembly concepts – be it one-piece flow, cycle assembly or modular cell production – are always based on product structure, volume and variant diversity. We also provide targeted advice on how to manufacture several products on one line. Although this is challenging, it can be successfully implemented with well thought-out planning and a high degree of flexibility.
To reduce set-up times, we implement proven methods such as SMED and anchor flexible changeover processes in daily operations. We rely on digital factory planning and simulation. This allows us to validate scenarios, identify bottlenecks and reliably evaluate investments.

Material flow and intralogistics
Rethinking logistics: shorter distances, lower inventories, greater security of supply

We analyze and design the entire internal logistics process. The focus is on developing end-to-end material flow and logistics concepts that shorten transport routes, reduce inventories and increase supply security. Especially in production, considerable losses occur due to waiting times, missing parts or excess stock if logistics processes are not precisely aligned with production requirements. This is why we attach particular importance to the seamless integration of logistics and production.
We optimize storage and retrieval strategies, define economical warehouse structures and develop concepts for the demand-oriented provision of materials – for example via supermarkets, supply racks or sequenced delivery.
When introducing Kanban, milk run or tugger train systems, we ensure a robust control system that reliably synchronizes consumption, replenishment and supply. We also support you in the integration of modern technologies such as AGVs (Automated Guided Vehicles), AMRs (Autonomous Mobile Robots) and conveyor technology in order to make optimum use of efficiency, flexibility and automation potential.
