A Business Case for Using UPTIME and OEE : 

A Business Case for Using UPTIME and OEE By Shane Browne Thanks to BlueScope Steel for the technical Guidelines

Why Change? : 

Why Change? YMA current Key Performance Indicators do not capture all our business losses; our focus is often on: * SAFETY STATS * * TONNES PER HOUR * * HOW FULL IS THE BUNKER? * This has been our culture for many years... We need a new measure that will help change our outlook on plant performance and how we can improve it

Definitions : 

Definitions UPTIME is a measure of the TIME a system or equipment has been “UP” and running. It came into use to describe the opposite of downtime, times when a system was not operational. Overall Equipment Effectiveness (OEE) is a unit-less measure comparing how well a system or equipment is running compared to the ideal system or equipment.

The Calculations : 

The Calculations UPTIME = Valuable Operating Time Calendar Time The strength of UPTIME is that it converts some calculated numbers into a visual bar that everyone can understand UPTIME can be calculated over a shift, a week , a month or a year

The Calculations : 

The Calculations OEE = Availability x Performance x Quality Availability % = The percentage of time that plant is available for production. Performance % = The percentage of Coal or Overburden mined per hour to the maximum demonstrated Quality % = The percentage of quality coal sent to the bunker out of total coal delivered produced per time frame.

UPTIME and OEE at Yallourn : 

UPTIME and OEE at Yallourn UPTIME will be the measure of time that our plant has been “UP” and running. The larger the UPTIME value in hours; means we are operating; maintaining and scheduling the plant more efficiently OEE will be the measure comparing how well our plant is running compared to the ideal plant. The larger the OEE value in % means the better we are operating and maintaining the mining plant

Question : 

Question Do you consider the combined metrics of UPTIME and OEE as a means of engaging our workforce to improve plant performance? To improve these Metrics, both Operations and Maintenance teams must work together as an Alliance to capture all opportunities to improve. What needs to be done? Improve accuracy of delay data Devise a system that captures Coal Quality Develop our current production system to update both UPTIME and OEE automatically and display. Decide on the types of visual indicators such as The Dashboard and there location Toolbox Topics to promulgate what UPTIME is and How we can improve it Thanks to BlueScope Steel for the kind use of their technical guides for my advanced learning and assistance in compiling this presentation
