Model Options

In an Optimization Model, constraints are in place so that the result follows your expected restrictions. Constraints, are enabled or disabled by model options, and shape scenarios. Sometimes you may want to enable or disable a set of constraints and compare its results against another scenario.

Enable or disable model options using the Options at the right side of the page. Model options will appear when the dataset includes the needed input data. For example, when there is target inventory data in the dataset, the option ‘Use target inventory’ appears.

The following model options are available, depending on your input:

  • Allow over utilization

  • Allow unfulfilled demand

  • Use target inventory

  • Include production cycles

  • Capacity smoothing

  • Batch Production

  • Batch Supply

  • Strict capacity limit

  • Strict min inventory limit

  • Strict max inventory limit

  • Frozen Periods

    Note

    The option “Frozen Periods” has a separate side panel. You can select the production resource/location/periods to fix production volume.

Page Actions

There are two actions available at the bottom right of the page.

  • icon Run optimization

  • download Download current production plan as excel

Run Optimization

After the selection of demand scenario, supply V&O and model options are made, click on the AIMMS Solve button icon to run optimization.

Status Bar

Save as a Business Scenario

At the bottom status bar of this page, there is an area showing current business scenario save. To save the current content on this page as a business scenario, enter a unique name and a description for this business scenario, and click Save. There is an overview of all business scenarios on the page Business Scenario Management and solution recap on the page Scenario Review.

Results

After you click Optimize, results are summarized on this page.

  • Demand/Production

    Demand and production volume are displayed in Status Bar. To view more key outcomes, and compare them with the previous solve, click on this status bar slot to bring up another dialog: Revenue, Unfulfilled Demand, Unfulfilled Revenue and Production Violation. Revenue is the production (or sold) amount \(\times\) selling price (or margin). Production Violation is the amount of production above the utilization limit (soft constraint). Above/Below Target/Min/Max Inventory is the amount of inventory outside of the range specified (soft constraint). Note that ranges of hard constraints can never be “touched”.

  • Barchart Resource Utilization Overview

    This table shows for each resource, the number of periods in different utilization types.

    ../../_images/ibp-scenario-evaluation-period-utilization-type.png

    In this example, there are 4 resources and 12 periods (months). From left to right, the first 3 resources are in Good utilization type for all 12 months. Meanwhile regards to the last resource, 9 months are in Good, 1 month is in Under utilization and 2 months are Inactive.

    Find the legend for this chart in the side panel.

    Note

    • Inactive: zero utilization

    • Under: below 50% of utilization limit

    • Good: between 50-100% of utilization limit

    • Over: above utilization limit

    Click a bar in this chart to inspect more details in the Barchart Capacity vs. Production and Line chart Inventory.

  • Line chart Inventory

    This is the monthly inventory level of all facilities.

    Note

    To enable contents for this chart, click to select a bar in Barchart Period Utilization Type.

  • Barchart Capacity vs. Production

    This is the monthly Capacity and monthly Production for a resource. The production bar is color-coded according to the legend to the right. An over-utilized facility is colored red. A facility with utilization above 95% but below 100% is colored orange.

    Note

    To enable contents for this chart, click to select a bar in Barchart Period Utilization Type.

  • Table Production Plan

    This table shows exact numbers of: Capacity, Production volume, and Utilization by month.

Frozen Periods

In the actual production planning practice, production plans may already have been determined 2 or 3 cycles prior, meaning that in the next 2 or 3 cycles production volume should be the predetermined numbers. To achieve that, you can use attribute Production Volume Input in table “Resource Product Data” “Bill Of Resource Data” to provide predetermined input data, and the side panel Frozen Period to toggle which resources should follow input data in frozen periods.

Once Production Volume Input exist in the dataset, a new page action zoomin will appear at bottom right. Clicking on that page action brings up an dialog page that compares the Production Volume Input and optimization solution on production volume.

At side panel Frozen Period, you can specify which resource(s) should follow Production Volume Input during which periods (frozen periods).
