Scheduled Time

Introduction

The latest update to MachineMetrics introduces automatic adjustments to scheduled time based on real-time machine activity and predefined shift schedules. This enhancement dynamically removes non-productive time from key production metrics such as Availability (OEE) and Parts Goal, providing a more accurate reflection of operational efficiency. By distinguishing between 'attended,' 'unattended,' and 'not scheduled' shift states, and allowing users to set an inactivity time threshold for unattended shifts, the system now offers tailored scheduled time adjustments to better match operational needs. Additionally, the advanced API architecture for managing scheduled time facilitates sophisticated integrations and customizations. These improvements align scheduled machine time with actual machine activity, ensuring precise OEE calculations, reliable data for strategic planning, increased user satisfaction, reduced manual adjustments, and improved overall production efficiency.

What is Scheduled Time?

Scheduled Time is the planned period when a machine is expected to be running and productive according to your operations schedule. This includes regular work hours, shifts, or any other set working times. MachineMetrics uses Scheduled Time to calculate important production metrics like Availability, which is the percentage of time the machines are actually running during scheduled periods, and Parts Goal, which is percentage of parts made during a run versus its expectations.

How It Works

The updated scheduled time system allows for more accurate production metrics by integrating several dynamics, including shifts, machine activity, and planned downtimes. This comprehensive approach ensures that "Scheduled Time" aligns more closely with actual operations.

Shifts

Shifts are the foundation for calculating scheduled time. The system distinguishes between attended and unattended shifts to ensure accurate metric calculations.

• Attended Shifts: Marked as "scheduled," enabling production metrics calculations even without an active Production Run.
• Unattended Shifts: If idle time exceeds the user-defined Unattended Inactivity Threshold, the system marks the downtime and subsequent periods as "unscheduled," allowing for continued Production Runs without negatively impacting metrics.
• Not Scheduled time: Times that are not allocated an attended or unattended shift are considered to be fully "unscheduled." Meaning, these timeframes wont effect production metrics even if the machine is running.

Machine inactivity and Activity Modes

Machine activity, including active and idle states, and various activity modes such as Planned Setup, influence scheduled time. These factors ensure that any deviations from expected activity are accurately reflected in production metrics.

• Active and Idle States: During Unattended shifts, real-time machine inactivity data helps dynamically adjust scheduled time, removing non-productive periods from metrics.
• Activity Modes: Modes such as Planned Setup impact Availability. Extended setup times are accounted for in the current system, influencing the overall scheduled time.

Downtimes

Downtimes categorized as "planned" are now marked as "unscheduled," offering flexibility and accuracy in data reporting. This allows the system to reflect true operational efficiency by excluding non-productive times from scheduled calculations.

FAQ's

Does this effect our Execution metrics?

No, Scheduled Time is used only from a Production metric standpoint. Execution uses all time queried to decern uptime versus downtime.

Does this change my historical OEE/Parts Goal scores?

Yes, this change will recalculate historical metrics to be aligned with the new methods. Shifts and their states can be backdated through your Machine Schedules settings so that the newer Attended/Unattended logic can effect your data prior to this change, as well as after.
