ZF's Model Factory Features Smart Interfaces Between Delivery and Production Logistics

  • The Model Factory streamlines goods deliveries and material flows
  • Comprehensive experience with autonomous transport systems is speeding up the development of autonomous driving functions
  • Initial use cases are being implemented throughout the year

Friedrichshafen. Since August 2017, ZF has been retrofitting a section of Plant 2 at its Friedrichshafen location with intelligent systems in order to streamline delivery logistics and internal production material flows. This project has been dubbed the ZF Model Factory. ZF hopes to simultaneously satisfy two of its technology challenges. Firstly, by developing and marketing practical solutions for intelligent transport systems, such as trucks, intra-logistic tractor vehicles and industrial trucks. Secondly, by contributing to other autonomous driving development activities. The experience gained from this project may shorten the development time for sensor, camera and intelligent control systems, such as ZF ProAI. In addition, by connecting Industry 4.0 with autonomous transport systems, production can benefit from more efficient processes.

ZF's Model Factory Features Smart Interfaces Between Delivery and Production Logistics

Modern industrial production is all about the turnover of goods. About 70 percent of the movement of goods during the production process consists of materials transport before the materials can be further processed by machines or other assembly equipment as part of the value-added chain. Manufacturers who organize the delivery and transport of components to workstations are able to see considerable improvements in efficiency and productivity with this connection.

This is only one of the achievements of the ZF Model Factory. Ilker Sari, head of the factory, said: “We want to combine the various areas of expertise in the ZF Group, including electromobility and autonomous driving, as well as commercial vehicle and industrial technology. Our pilot projects are like display windows of the future.” In addition to optimizing internal production processes and interconnecting Industry 4.0 and smart logistics approaches, the company uses the pilots as support in targeting the commercial vehicle and industrial technology markets. “Autonomous driving has strong potential – not only on public roads but also within private compounds,” added Sari. “We want to leverage the benefits gained from developing autonomous driving functions within the commercial vehicle and industrial technology markets, showing that we are a leader in these sectors.”

Use Case 1: See – Think – Act at the depot

This is not just about conventional driverless transport systems, as they have been successfully used for decades; those vehicles are operated primarily on defined and partially blocked-off routes to perform simple transport activities. “For us, it’s about vehicles that interact with their environment, using smart sensors and an intelligent control system linked to the inventory management system. These vehicles are flexible and can adapt to actual demand,” explained Sari. The autonomous transport systems in the ZF Model Factory can master a multitude of new functions: They can overtake, avoid obstacles and search for alternative routes when roads are blocked. Thanks to intelligent control systems and interconnected guidance systems, material transport can be perfectly prioritized and controlled, improving lead times, increasing availability and, therefore, improving buffering in production. According to Sari: “A technology that contributes to improved buffer inventories in production and logistics processes is appealing for the entire industry.”

This project starts one step prior to the receipt of the raw material. Currently, it is not usual to have the specific time of arrival for a truck from a forwarding company. Waiting times at the gate and incoming goods area are normal and transport papers must be entered manually into the materials management system. The ZF Model Factory team is working together with experts from supply chain management on a scenario that is aiming toward digitalization, shorter waiting times and the optimal use of downtimes. A tracking system keeps ZF, as the goods recipient, informed of the location of the delivery truck at all times and can predict its arrival time down to the minute. It also records whether the driver has to maintain break times after delivering the goods. Unloading times are therefore scheduled to coordinate with the driver’s break times. It is also conceivable that the trailer can be disconnected prior to entering the company's grounds and be moved to the incoming goods area by autonomous transport systems. BLE tags record digital data about possible shocks or other events during the freight transport. This data as well as information from the shipping documents can be transmitted digitally to the materials management system.

As soon as the delivery truck approaches the company's premises, the necessary forklift trucks are assigned to the unloading area. This can considerably reduce truck idle and unloading times, and eliminate long wait times at the gate.

Use Case 2: Bite-sized in assembly

Every day, several hundred assembled ZF commercial vehicle transmissions leave Plant 2 in Friedrichshafen. These transmissions consist of up to 1,000 individual components. With over 100 large shipments per hour, the logistics process comes together in the final assembly area. For ZF, as for any production company, defining the logistics for the assembly processes is of significant importance. In this scenario, the ZF Model Factory is setting a new trend as so-called “delivery” of material to the assembly stations, including preparation, is being done autonomously. The starting points are today’s milk-run trains that bring the goods to assembly in the precise production sequence (“just-in-sequence”). Material distribution and milk-run trains are controlled manually. The ZF Model Factory has completely done away with the classic milk-run trains. Instead, autonomous transport systems directly supply the containers storing the pre-assembled parts to the assembly area. With this approach, logistics processes can be better and more precisely controlled.

In order to optimize the set-up of these processes, the material flow logistics planners from the ZF plant are directly involved in the Model Factory. Additional initial use cases will be implemented throughout the year and then continuously developed. In the meantime, passenger car and commercial vehicle sectors will also benefit: Experience from the model factory is directly incorporated into advanced engineering for autonomous driving functions.
