Assessing the Weight Metrics

You can use weight to view the predefined metrics, drill-down, and analyze data.

To filter on structure, you can decide on which configuration the assessment is applied. Once you select a configuration, the assessment roll-up starts. The rolled-up value versus the objective value is displayed on the configured element.

This task shows you how to:

Display the Metrics

You can display the multi-KPI dashboard in Weight and Balance.

  1. From the Compass, drag the Weight and Balance app from the Compass to your dashboard.
  2. Optional: To verify the server status, click Check server status and select Dispatcher, Orpheus Controller and Orpheus Instance.
    You can see blue indicators when the status is valid, or gray indicators when it is not. A tooltip indicates what you should do or provides the index scan date.
  3. Search for an element containing metric values in the 3DSearch and drag it onto Weight and Balance.
    The weight, center of gravity, and inertia matrix metrics are displayed.

    Note: The label contour of the metrics is:
    • Gray (no contour) when no objective has been defined for this element.
    • Green when the objective is reached.
    • Yellow when the objective is in the minimum - maximum interval.
    • Red when the metric has an objective but no value, or when the objective is not reached, or out of the minimum - maximum interval.
  4. Optional: Select a Configuration Filter.

    If several configurations are available for this item, you can select one of them. You can also compare different configurations.

    Tip: When your component has more than six configurations, a search box is displayed and you can filter the list.

    The web app displays the consolidated metrics for this item. If you click the thumbnail, a tooltip displays the metric values.

  5. To display all the existing metrics, click All KPIs .

When a label is selected, the metric name is displayed at the top of the window (Global Scoring > Weight).

Assess the Weight

You can see the detailed analytics of the weight.

  1. Click the weight's metric label.
  2. Compare the weight of the item and the defined targets.
    The following information is displayed:
    • Weight: Mass of the item, with the fluid weight included when the item (a pipe) contains a fluid; therefore, the mass of the item is called the wet weight. For more information, see Assess the Fluid Weight and the Dry Weight.
    • Objective: Value to reach for the selected element. There is not any value nor assessment gauge when objectives have not been defined (see the image below).
    • Tolerance: Statistical consolidation of tolerances on children.
    • Confidence: Consolidation of the confidence percentage.
    • Budget: Sum of all budgets defined on every level of the structure.
      Tip: Click More Details to visualize other analytics such as Tolerance and Budget.
    • Assessment gauge chart: An assessment of a specific metric regarding its objectives. A colored gauge replaces the image with the "No objectives defined" information, when objectives have been specified. For more information, see About the Assessment Gauge.
    • Structural Distribution: A pie chart to focus on the weight distribution for the selected element. For more information, see Structural Distribution.
    • Analytics: A pie chart to verify the types associated to the metric. See Access Complementary Analytics Information
    • Weight Trend: A trend chart appears only if you added metrics to the timeline before. You can select other attributes in the list. See Display the Timeline Chart.
  3. To go back to the weight, center of gravity, and inertia matrix metrics' page, click Global Scoring .

Assess the Fluid Weight and the Dry Weight

When a physical product includes pipes filled with liquid material, the fluidic mass is computed. A separate secondary analytics provides the fluidic weight and the dry weight.

Pipe without fluid:

Pipe with fluid:

Before you begin: To perform this task,
  • To compute the wet weight of the product, taking the LineID modification into account, open Weight Analysis.
  • From the 3DEXPERIENCE or the 3DDashboard, search for an element with pipes containing fluid in the 3DSearch.
  • Do one of the following:
    • From the 3DEXPERIENCE, open the element and click Weight and Balance from the Data Intelligence section of the action bar.
    • Or from the 3DDashboard, drag it onto the Weight and Balance app to compute the metrics.
  1. Click the weight's metric label.
    Notes:
    • The fluid mass affects the value of the weight metric. The total mass of the item is: the mass of the structure, plus the fluid weight.
    • The value of the inertia matrix varies with the liquid weight.
    • The value of the center of gravity remains the same for leaf nodes as the fluid's center of gravity is approximately the same as the pipe structure's.
    • For intermediary nodes, the fluid weight impacts their center of gravity, as it is proportional to the wet weight of its leaf children.
  2. To get the detailed analytics of weight metric as dry and fluid weight, click Analytics and select Dry Weight, Wet Weight.

    A pie chart with color codes displays the distribution of the dry (gray), fluid (light blue) and wet (dark blue) weight:

    Dry weight, wet weight pie chart

    The wet weight is the sum of dry weight and fluid weight: . It is indexed in the Cloud View.

  3. To compare the business values of the weight metric with previous ones, select the Dry Weight, Wet Weight Trend. For more information, see Add to the Timeline and Display the Timeline Chart.
    A historical graph displays the previous dry and fluid weight analytics, saved during a timeline edition.

    There is a legend for the metric values, the objectives and the dry and fluid weight trends, therefore, you can also compare the wet weight value with the predefined metric objectives.

  4. To go back to the weight, center of gravity, and inertia matrix metrics' page, click Global Scoring .

Structural Distribution

You can see the metric structural distribution in an assembly and drill-down to the metric structure from an item.

You can display its consolidated metric information in a pie chart or multi-list view, and customize it in the assessment apps only.

  1. Click the label of the metric.
  2. Select Structural Distribution to get an assessment of an item from the assembly in a dedicated tab. You can display the assessment in a pie chart view (default option) or in a multilist view:
    • Pie chart view:

      By default, the pie chart view is displayed.

    • Multilist view (example of a Cost metric).

    • Note: You can switch between the pie chart view and the multilist view by clicking the button or in the right corner of the panel.

      The multilist view is available for all the assessment apps and provides all the metrics in a single view along with its drill-down. There are headers and subheaders for each metric based on the cockpit. You can customize the display of the headers by selecting the following contextual commands on the cells. For more information, see the next step.

      The first column displays the title header of the item along with its revision and its structure in a tree. The multilist view also displays data coming from different facets, for example: Manufacturing, Operation etc. The data coming from the facet is one level below the context item. A mask appears on the type icon: .

      The second column displays the metric values along with the assessment icon (only if the objective is set).

      Assessment Icon Assessment Detail

      On Target

      If the value and its objective are the same.

      Over or Under Target

      If the value is outside target range of the objective.

      Within Target

      If the value is within the target range of the objective but is not the targeted value. This case is specific to the objective within range.
    • Here is an example of an assessment icon:

    You obtain, for example, a consolidated metric information of a metric from its Engineering or Manufacturing structure.

    Note: The drill-down is always one level.
  3. Click an element either in the pie chart or in the dedicated tab and select a contextual command.

Access Complementary Analytics Information

You can filter complementary analytics information.

  1. Click the weight's metric label.
  2. Click Analytics .
  3. From the list on the right side of the window, select an analytics to display its various categories in the pie chart.
    The list contains the following analytics:
    Analytics Description
    Lifecycle Describes the occurrences on which a metric value is defined with the metric kind. Five metric kind categories are defined: Computed, Measured, Estimated, Declared and Inherited.
    Missing Describes the occurrences on which a metric value is missing or has to be ignored by the user. Three categories are defined: Missing Value, Valued and Ignored.
    Note: If a null density is applied or the weight is at 0kg, the defined category is Valued, not Missing.
    Threshold Percentage is a value defined in the data model. By default, the value is 70%, but it can be modified in the matrix query language. For more information, see the cookbook available in the directory called DES server installation runtime: [INSTALLDIR]\Scala\Cookbook - How to define a new Balance type vXX.pdf. Two categories are defined: Below and Over the threshold. Depending on whether the sustainability confidence value is over the threshold or not, the value corresponds to one category or another.
    Reaching targets Displays the number of occurrences belonging to the Sustainability Bill of Material according to their reaching target status in a pie chart.

    There are four status categories:

    • Reached: the occurrences have a target and have reached the target.
    • Failed: the occurrences have a target but do not reach the target.
    • No value: the occurrences have a target but no value.
    • No objective: the occurrences do not have a target.

    An occurrence reaches its target if:

    • Its value is between the minimum and maximum values defined for the objective.
    • The metric behavior is “LowerReach” (like for the sustainability) and the value is below the objective or the maximum objective.
    • The metric behavior is “UpperReach” (like for the Power creation) and the value is over the objective or the minimum objective.

    Note: If an occurrence is not part of the Sustainability Bill of Material because its father overloads the values, this occurrence is not taken into consideration in the pie chart.

    When you hover over a category in the pie chart, the occurrences belonging to this category are colored in the work area:

    • Red: for occurrences belonging to the Failed category.
    • Green: for occurrences belonging to the Reached category.
    • Orange: for occurrences belonging to the No value category.
    Tip: Selecting Reveal all categories colorizes all occurrences according to their reaching target status.
    Dry Weight Wet Weight A pie chart with color codes displays the distribution of the dry (gray), fluid (light blue) and wet (dark blue) weight. For more information, see Assess the Fluid Weight and the Dry Weight.
    Human Activities Solving Quality analytics display the number of activities accurately solved.
    Note: The administrator can customize this list to display other analytics. For more information, see the cookbook available in the DES server installation runtime directory: [INSTALLDIR]\Scala\Cookbook - How to define a new Balance type vXX.pdf.
