Planning and control of production processes

Manufacturing Control

Manufacturing control is the central operational nervous system of a manufacturing company, ensuring that production orders are completed on time, in the correct quantities and to the required quality standards. By carefully monitoring and adjusting capacity, it maximises value creation and minimises lead times.

At a glance: Understanding production control

Definition of manufacturing control

The definition of manufacturing control encompasses all operational measures for scheduling, monitoring and ensuring the fulfilment of production orders within a defined timeframe. It acts as the executive link between higher-level planning and physical implementation on the shop floor. The aim is to proactively manage disruptions and keep the material flow moving continuously.

Manufacturing control and manufacturing planning

Whilst manufacturing planning sets out the medium- to long-term programme and demand planning, manufacturing control focuses on day-to-day operations in the short term. Production control and production planning thus form an iterative system in which planned targets are continuously reconciled with actual feedback from production. Only seamless synchronisation of both disciplines prevents bottlenecks and enables efficient capacity utilisation.

Tasks in manufacturing control

The primary tasks in production control include order release, sequencing, and the ongoing collection of capacity and operational data. Furthermore, production planners must initiate immediate countermeasures in the event of machine downtime or material bottlenecks to safeguard delivery dates. A transparent information architecture is essential for the smooth coordination of these tasks within production control.

The core areas of production control

The effectiveness of modern order processing is based on the seamless interplay of several operational components. These core components must be systematically coordinated to avoid information gaps between the shop floor and production planning. Considering individual factors in isolation inevitably leads to sub-optimal production utilisation. Rather, excellent control requires a harmonised interplay of methodology, digital support and procedural discipline. The following elements form the indispensable foundation for smooth and efficient production.

Load-Oriented Production Control

Load-Oriented Production Control (BOA) is a highly effective methodology for protecting workshops from overload and drastically reducing lead times. Under this approach, new orders are only released if the planned workstation capacities do not exceed a defined load limit. In logistical practice, this approach prevents the notorious ‘funnel effect’, where material builds up in front of bottleneck machines and hinders flexibility. By strictly capping work-in-process stocks, companies manage their production in a significantly more agile and responsive manner. We implement this logic in a targeted manner to guarantee our customers in piece-goods manufacturing a stable and predictable sequence of orders.

Software for Manufacturing Control

Without powerful IT systems, the complexity of today’s variant-based manufacturing can no longer be managed, which is why modern production control software is essential. Systems such as MES (Manufacturing Execution Systems) or specialised APS modules (Advanced Planning and Scheduling) process real-time data directly from the machines and reconcile this with ERP specifications. In the practical context of supply chain management, these tools enable dynamic rescheduling in the event of disruptions such as tool breakage or missing purchased parts. Success, however, depends largely on data quality and the accurate representation of physical constraints in the digital twin. We support companies in selecting and embedding the optimal production control software into their processes to establish a seamless flow of information.

Sequencing and Capacity Planning

Precise sequencing and capacity planning determine whether set-up times are minimised and machines are utilised to their full potential. Schedulers must weigh up on a daily basis which order sequences promise the highest efficiency without jeopardising committed delivery dates. In operational logistics, this means forming set-up families and proactively prioritising bottleneck resources. Faulty capacity scheduling inevitably leads to costly overtime shifts or production line stoppages. By introducing heuristic optimisation methods, we stabilise this process and create a robust foundation for the shop floor.

  

Focus on manufacturing control tasks

Manufacturing control tasks form the operational backbone of modern manufacturing by translating theoretical planning targets into a physically congestion-free flow of materials. To maximise value creation, machine capacities, personnel and material availability must be orchestrated in real time and corrected immediately in the event of deviations. As a Fraunhofer spin-off, we at ebp-consulting implement manufacturer-neutral control mechanisms that consistently eliminate waste and ensure a high-performance factory organisation.

Order Release

Order release marks the controlled start of physical production and only takes place following a granular check of material and resource availability. Its core function is to prevent orders from being scheduled without being checked, thereby causing queues at bottleneck machines. There is significant potential for optimisation here through the drastic reduction of work-in-progress (WIP) stocks, which stabilises lead times and reduces capital tied up on the shop floor. In operational practice, we use load-oriented approaches (BOA) or Kanban pull systems to link release strictly to actual material requirements. In this way, we transform rigid push logic into a self-regulating and congestion-free order processing system.

Sequencing

Sequencing defines the exact chronological order in which approved production batches are processed at specific workstations. The focus is on the intelligent grouping of production orders with similar set-up conditions in order to systematically minimise time-consuming tool changes and unproductive machine changeovers. The greatest potential for optimisation lies in the significant increase in Overall Equipment Effectiveness (OEE) achieved by reducing downtime. In practice, we tackle this task by using advanced APS (Advanced Planning and Scheduling) systems and heuristic optimisation methods, which form set-up families and dynamically adjust machine utilisation in real time. This maximises value-adding throughput and guarantees the highest level of on-time delivery.

Capacity Management

Capacity management continuously reconciles the upcoming order volume with the physically available machine and personnel resources. It acts as a dynamic balancing mechanism that proactively prevents impending overloads at critical bottlenecks and intelligently redistributes workloads. Untapped potential is often hidden in a lack of transparency, which leads to buffer times or makes expensive overtime shifts necessary. We establish data-driven capacity balancing based on the Theory of Constraints (ToC) to fully exploit the production system’s maximum rhythm. In doing so, we harmonise production, ensure on-time delivery and establish robust capacity limits.

Material Provision

Material provision orchestrates the physical replenishment of raw materials and components from intralogistics, precisely synchronised with the takt time of the assembly lines. To avoid overcrowded areas on the shop floor, manual search times and handling errors, the material must arrive at the right place at the right time. The integration of automated provision concepts offers significant potential for optimisation, minimising dwell times and reducing capital tied up in inventory. In our consultancy projects, we achieve this through just-in-time or just-in-sequence call-offs and the seamless integration of automated guided vehicles (AGVs/AMRs) with production control. This eliminates manual replenishment errors and guarantees a constant, uninterrupted flow of materials.

Production Data Acquisition (PDA) and Process Monitoring

Continuous production data acquisition (PDA) and process monitoring form the digital backbone of production control by analysing production progress, processing times and scrap volumes in real time. It provides production planners with the essential transparency needed to react immediately with corrective measures in the event of machine faults or material bottlenecks. The potential for optimisation here lies in bridging the information gap between planning and the shop floor, thereby significantly reducing unplanned downtime. In practice, we rely on the integration of high-performance Manufacturing Execution Systems (MES), which serve as a digital feedback loop and continuously improve the empirical database for future planning cycles. In this way, we transform reactive action into predictive, highly data-driven control of factory organisation.

  

Areas of Application for Manufacturing Control

In the highly diverse mechanical engineering sector, manufacturing control demonstrates its full potential when customised assemblies need to be synchronised with standard components on the same production lines. ebp-consulting applies in-depth specialist knowledge to translate the complex bill of materials into a smooth production rhythm. Another key area of application is the automotive supply industry, where strict just-in-sequence calls necessitate absolutely error-free and precisely timed control. Through our methodical consultancy expertise, we establish resilient control loops in these highly dynamic environments that autonomously absorb disruptions. We ensure that material provision and machine utilisation in every sector are precisely calibrated to the specific logistical requirements.

Questions and answers on Manufacturing Control

What impact does a high level of work-in-progress (WIP) have on production control?

An excessively high level of work-in-progress (WIP) clogs up production lines and hinders the flexibility of the entire control system. In our consulting practice, we frequently observe that this leads to a massive increase in lead times and that rush orders can only be processed at great administrative cost. Reducing WIP is therefore often the first and most important lever for making production manageable and agile again.

How do the ‘push’ and ‘pull’ principles differ in practice?

Under the ‘push’ principle, orders are pushed into production based on planning data without taking current workshop utilisation into account, which often leads to bottlenecks. The ‘pull’ principle, such as Kanban, on the other hand, only triggers production when an actual sink or customer demand arises. From a logistical perspective, we implement pull systems as they are self-regulating, minimise stock levels and drastically reduce lead times.

What role do bottleneck resources play in order processing?

Bottleneck resources dictate the maximum output and rhythm of the entire production system. According to the Theory of Constraints (ToC), the entire production control system must focus exclusively on the maximum utilisation of this bottleneck. We implement targeted buffer mechanisms for our clients upstream of these stations to prevent the bottleneck from idling and thus ensure overall efficiency.

How important is real-time data collection via an MES?

Without reliable operational and machine data (BDE/MDE), production planners are effectively managing production blind. A Manufacturing Execution System (MES) provides the necessary real-time transparency to respond immediately to disruptions such as machine downtime. In our projects, ensuring high data quality is the critical success factor in making digital control tools usable in the first place.
