Wiegand-Glas selects planning software across four plants

Wiegand-Glas has selected planning software for four German manufacturing plants. The sedApta systems will coordinate demand, inventory and production schedules; implementation results have not yet been disclosed.


IN Brief:

  • Four named German plants will use Elisa Industriq’s sedApta planning technology.
  • The project targets demand forecasting, stock management and factory scheduling across the glass operation.
  • Wiegand-Glas reports daily glass-container capacity above eight million units; deployment outcomes remain unreported.

Wiegand-Glas has selected Elisa Industriq’s sedApta planning software for four German manufacturing plants, intending to bring demand forecasts, stock records and factory schedules into a coordinated planning process. The group reports combined capacity exceeding eight million glass containers per day across the sites. The 20 October announcement establishes the software selection but does not identify a contract value, installation timetable or achieved production saving. Factory performance will depend on the information exchanged with existing systems and the physical constraints imposed by the glass manufacturing process.

The four plants are located in Steinbach am Wald in Bavaria and Ernstthal, Großbreitenbach and Schleusingen in Thuringia. Wiegand-Glas produces packaging for food and drink customers and also operates PET, logistics and energy businesses. Its description of more than eight million preforms and PET containers produced daily refers to a separate product category; the figure should not be combined with the glass-container output to imply one interchangeable capacity pool. Planning across the glass sites must account for the specifications that each line can manufacture.

The sedApta offering covers demand planning, inventory management, production planning and factory scheduling. Demand projections estimate the quantity and specification of products customers are likely to require. Inventory systems establish what is available for dispatch or reserved, while production planning allocates resources to meet the expected order mix. Detailed scheduling then sequences jobs within machinery, staffing and material constraints. Connecting these processes is intended to reduce mismatches between a sales forecast and the quantities a factory can realistically produce with its current equipment.

A container-glass furnace operates continuously within temperature and process limits, and a production campaign must account for the forming equipment attached to it. Changes in product design, colour or size can entail tooling adjustments and losses in available operating time. A plan that merely balances order quantities on paper could therefore be impossible to execute economically on a particular line. Maintenance windows, raw-material delivery and the availability of suitable packaging equipment impose further restrictions that need to be reflected in any scheduling model.

Elisa Industriq says scenario planning should help Wiegand-Glas compare order requirements with available capacity and stock. A proposed change in the bottle mix, for example, might require a different production sequence or additional finished goods held before dispatch. Making those effects visible earlier would give production planners a firmer basis for accepting, rescheduling or reallocating orders. The company has not detailed the software’s optimisation algorithms or confirmed which existing enterprise, shop-floor or warehouse systems will connect to the new platform.

A common planning view could allow planners to examine the four plants’ capacity constraints together rather than forecasting each site separately. Moving work between locations is not necessarily an option, however: tooling, container geometry, furnace conditions, available materials and delivery distances can rule out apparent spare capacity. The useful outcome is a realistic assessment of where an order can be produced and supplied, including the costs and risks of any alternative. The agreement does not establish that cross-plant production transfers have begun.

Glass manufacturing schedules must reconcile long production campaigns with changes in customer orders, stocks and line capacity. Michael Fatum, managing director of Elisa Industriq Germany, described these constraints as part of the need for coordinated planning when the selection was announced. Common sales, operations and production assumptions could improve the basis of the schedule, provided machine availability, lead times and inventory counts are accurate. The supplier has released no live operating figures for changeover rates or missed deliveries from this planned deployment.

Finished-container inventory can absorb differences between customer delivery schedules and economically sensible production campaigns. Holding excessive stock, however, ties up warehouse capacity and working capital, while insufficient stocks increase exposure to missed deliveries when a glass line is committed to another specification. Combining stock records with realistic line schedules should expose those trade-offs earlier. Neither a stock reduction percentage nor an independently verified order-fill improvement has been announced, and those outcomes will depend on accurate inventory and production data after implementation.

Wiegand-Glas reported turnover of €730m for its 2025/26 financial year and employs more than 2,100 people worldwide. Those are wider group figures, not the software programme’s contract value or an estimate of financial benefit. Installation, integration, training and validation still need to take place before the planning environment can be judged against operating results. The partners have not supplied a staged rollout timetable, named integration partners or numerical targets for finished-goods inventory and schedule adherence.

Implementation will require interfaces to existing plant systems, staff training and validation against actual inventory and machine availability at the four sites. Once operational, the programme can be assessed through finished-stock cover, adherence to production schedules, line changeover time and delivery performance. Its immediate purpose is to match the timing and specification of orders to available container-glass production campaigns, where furnace operation, forming equipment and tooling impose real physical limits on resequencing.
