SC Navigator 26.12.1

Date November 10, 2026

• New Features

  • Result overview tables (Single Runs and Batch Runs on the Overview of Solutions dialog, the Select Results Data dialog, and Results Data on the Manage Data page) now show key optimization metrics, including objective values, costs, demand KPIs, open facilities, and custom objectives - allowing runs to be compared at a glance. The Batch Optimization page also shows a detailed result summary in the View Results tooltip.

• Improvements

  • Several memory improvements have been made, making it less likely that sessions with large datasets run out of memory:

    • The implementation of constrained CoG optimizations has been improved. They should start solving sooner and use less memory, especially on larger datasets. Results are unchanged.

    • Loading a dataset now uses less memory when the Transport Ratio sheet is empty: the checks for transport ratios are skipped when there are no ratios to check.

    • Reading large datasets with many transport lanes now uses less memory, especially when no transport capacities are given.

    • Center of Gravity drive-time runs with a small maximum drive time now need much less memory and time to prepare the drive-time grid.

    • With the new attribute ‘Remove Lanes longer than Maximum Drive Time’ on the Settings sheet, these lanes are left out during data processing, so large datasets use less memory. Relax Maximum Drive Time and the infeasibility analysis cannot add these lanes back.

    • Large models optimize faster and use less memory when nothing restricts how products travel to customers, such as transport or warehouse capacities, minimum volumes or fixed costs. The optimal total cost is unchanged.

    • Importing an Excel dataset now uses less memory: the data validation keeps less in memory, and memory left over from earlier work in the same session is released before a new import starts.

  • For some larger models, the performance has been improved when running ‘Solve Constrained CoG’ where the objective is to ‘Minimize Number of CoGs’.

  • SENSAI Pro now answers capacity questions faster and more reliably. It reads the capacity of a warehouse, production facility or transport lane in one step, without first looking up which capacity step applies.

  • SENSAI Pro can now answer questions about the KPI Overview page. Ask about cost, revenue, profit, demand fulfillment, lead time, cost per unit or open facilities, for each period or for the whole horizon.

• Bug Fixes

  • Enabling Load Coloring on the Center of Gravity map caused warehouse locations to disappear.

  • On the KPI Overview, the custom objective revenue for Transport (Direct) was shown under Transport (InterResource), and the other way around. Each transport type now shows its own revenue.

  • On the Warehouse Results page, inventory capacity could be shown incorrectly, including being marked as “unlimited” by mistake. This happened when a warehouse’s throughput capacity and inventory capacity used different steps. The inventory capacity bar and its “unlimited” label now match the inventory utilization figure.

  • The infeasibility analysis can now exceed the maximum capacity of a transport lane by more than 2,500 units when Transportation Capacity is allowed. Before, lanes with a Minimum Capacity, Fixed Cost or Force Open could only go 2,500 units over their maximum, so the analysis could fail to find a solution.

  • When trying to save results using an invalid name (e.g. an already existing name), the invalid name dialog returned users to the input dataset dialog instead of the save results dialog.

  • Loading a dataset or saved results while a Trade-Off Analysis or Center of Gravity Trade-Off Analysis was running, and confirming that its results would be lost, did not stop all of its runs. Queued runs still started, and running Center of Gravity runs kept going. Now all runs of the analysis stop.

  • When the infeasibility analysis stopped at its time limit before finding a solution, it showed “The model is still infeasible, please allow more violations”, which does not help when all violation types are already allowed. It now asks to increase the Time Limit for Optimization on the Control Panel page.

  • Clicking View Results on the Overview of Solutions dialog for a run that finished with errors did nothing. It now shows a message that the run has no results to load and suggests running the optimization again.

  • The Relax Minimum Production Capacity and Relax Maximum Production Capacity options also relaxed the minimum and maximum ratios on the ‘Warehouse Ratio’ sheet, while the Relax Minimum Warehouse Capacity and Relax Maximum Warehouse Capacity options did not. Warehouse ratios are now relaxed by the warehouse capacity options. Results may change for scenarios that use warehouse ratios and relax production or warehouse capacity.

  • SENSAI Pro sometimes indicated that saved results were not available for comparison, especially results saved in an earlier session. It now compares against any saved results you name.
