Changeover KPI Matrix

This page is mainly occupied by a matrix that uses different color shades to represent a selected parameter in relation to the format changes made on the machine.

The purpose of the visualization is to show the user how the selected parameter is valued depending on the type of format change. The data used for the analysis are historical machine data, meaning that the calculated parameter value and the types of format changes presented are strictly dependent on the information that has actually been recorded on the machine.

At the top of the page, a series of controls are provided, allowing the user to set the scope and direction of the analysis. Among the parameters to be defined for the analysis are:

  • time interval: the data used for the analysis will be those related to the selected interval;

  • sub-machine: if the reference project is multi-machine, it is possible to choose the sub-machine on which to base the analysis;

  • filters: as in most MAT pages, filtering can be applied to exclude portions of data where certain conditions are met from the analysis;

  • phase: since a format change can consist of several phases, it is possible to apply the analysis to a single phase. Alternatively, the analysis can be applied to the entire format change, considered as a set of individual phases;

  • KPI for analysis: the user is asked to select the KPI on which to base the analysis. These include: money lost/gained, time lost/gained, efficiency, average time, number of changes, and time spent.

In the central part of the visualization, both some generic information calculated on the overall format change data and a matrix are displayed, allowing for a better appreciation of the selected KPI in relation to each individual type of format change. The color of each cell in the matrix will depend on its value. By hovering the cursor over the various cells, a pop-up will appear, providing additional information.

In addition to the matrix view, specific controls allow the data to be displayed in other formats, such as tabular or as a time-based chart.
