OEE Chart Reports

note

This module is designed to generate comprehensive OEE Chart Reports using advanced filters and interactive charts. It enables users to analyze Overall Equipment Effectiveness (OEE) and production data with accuracy based on selected criteria.

1. Generate OEE Chart Reports​

Step-by-Step User Guide​

1.1 Access the OEE Chart Report Section​

  1. Open the main menu
  2. Navigate to Production and Quality
  3. Click Reports
  4. Select Info Graphics – OEE Charts Reports

1.2 Understanding the Search Fields​

note

All fields marked with (*) are mandatory.

FieldDescription
Date RangeSelect the reporting period (Last 7 Days, This Month, Custom)
CategoryChoose Machine or Operator
Part StatusFilter valid production records
Report TypeSelect the required report using the carousel

1.3 Field Validations​

  • All mandatory fields must be selected
  • Date Range defaults to the current system date
  • Dropdown values are predefined to avoid incorrect input
  • If no matching data exists, the system displays No Data Available

1.4 Generate the Report​

  1. Select required filters
  2. Choose a report from the carousel
  3. Chart updates automatically
  4. Hover on the chart to view details
  5. Click Clear to reset filters

1.5 No Data Found Message​

If no data matches the selected filters:

No Data Available

Recommended actions:

  • Verify date range
  • Check machine or operator selection
  • Confirm production data exists for the selected period

2. Common Rules Used Across All Reports​

These rules apply to all OEE and Production reports.

2.1 Task Types Considered​

Only the following task types are included:

  • TK – Task type
  • BLK – Bulk entry
  • HBLK – Hourly entry
  • ASM – Assembly process

2.2 Part Status Considered​

Only valid production records are included:

  • APV – Approved
  • CAPRVD – Conditional Approved
  • CRJ – Casting Rejection
  • HI – Hold for Inspection
  • HR – Hold for Research

2.3 Shift-Based Day Logic​

All reports use shift-based day calculation.

Production Day = Operate Date + Shift Interval

This ensures correct handling of:

  • Night shifts
  • Shifts crossing midnight

2.4 Scheduled Maintenance (Idle Time)​

Idle time is identified dynamically.

Only idle reasons with labelCode = SM are treated as Scheduled Maintenance.

tip

Idle reasons are configuration-driven. No hardcoding is used.

2.5 Control Task Idle Time Reflection​

Idle time entered through the Control Task screen is also reflected in the OEE Chart Reports.

  • If idle time is added in Control Task, the same idle duration becomes part of the report data for the relevant machine and reporting period.
  • If that idle reason is configured with labelCode = SM, it is treated as Scheduled Maintenance Idle Time in OEE calculations.
  • If the idle reason uses any other label code, it is still reflected in report calculations that include idle time, but it is not treated as Scheduled Maintenance.
note

This means Control Task idle entries are reportable in OEE charts, while the idle reason configuration decides how that time is classified in the final calculation.

3. Common Time Definitions (Current)​

Available Time
  • Machine/Day/Month reports: total selected range minutes (24/7 basis), with idle shown separately in breakup tables.
  • Operator reports (DMeX): sum of operator shift durations from OperatorShiftLog.
  • Operator reports (IoT): sum of operator shift durations from OperatorShiftPlanning.
Production Time
  • For machine/day/month reports:
    Production = ((Cycle Time + Handle Time) / 60) × Quantity
  • For operator production details popup:
    • Full Cycle Time = controltask process cycle time
    • Operator Split Time = partExecutionSplit time for that operator
    • Operator Effective Time = split time if split exists, else full cycle time
note

PartExecutionSplit logic is applied only in Operator-wise OEE flows (Operator Wise OEE and Operator Wise With Idle Time).
It is not applied to machine/day/month OEE detail popups.

note

PartExecutionSplit-based operator time is considered only when the linked controltask entry passes valid part-status rules.

For operator split-time:

  • Split time is counted only for approved work.
  • The linked controltask must be:
    • Approved (APV) or
    • Conditional Approved (CAPRVD)

4. Report Formulas​

Below are the active formulas used in the dashboard.

Purpose: Daily machine efficiency

  • Available = total range minutes for that day
  • Idle = scheduled maintenance idle minutes
  • Production = cycle-based production time
  • OEE (%) = Production ÷ (Available − Idle) × 100

5. How to Interpret the Results​

ObservationMeaning
High OEEEfficient utilization
Low OEEDowntime, maintenance, or low output
Operator With Idle OEE > Operator OEEMore idle involvement
Zero ProductionNo execution, maintenance, or no shift

6. Final Notes​

info

If values differ between reports, always verify:

  • Which formula family is used: operator vs machine/day/month
  • Whether idle time is part of denominator logic
  • Whether operator split-time was applied (operator reports only)

All reports are:

  • Shift-aware
  • Maintenance-aware
  • Configuration-driven
  • Fully aligned with Grafana
