Availability. Availability is the first of the three OEE factors to be calculated. It accounts for when the process is not running (both Unplanned Stops and Planned Stops). Formula: Run Time / Planned Production Time. Example: 373 minutes / 420 minutes = (%) Performance. Performance is the second of the three OEE factors to be ...

Jun 13, 2013· Equipment Availability – Concept Issues _____ Author: Jogeswara Rao Kavala. The Objective: In many industrial situations, performance analyses often lead to queries about the Equipment Availability. This document mainly gives the concepts of the same and discusses about the calculations and issues in calculations. The Availability MTTR, MTBR
OEE (Overall Equipment Effectiveness) is a "best practices" metric that identifies the percentage of planned production time that is truly productive. An OEE score of represents perfect production: manufacturing only good parts, as fast as possible, with no downtime. OEE is useful as both a benchmark and a baseline:

"Maintenance is the factor that offers mining companies the best opportunity to influence and control the performance and availability of their equipment," say Abelardo Flores and Jim McCaherty, coauthors of "Performance Metrics for Mobile Mining Equipment," a guideline created to assist mining equipment users in the ...
equipment itself, the process being performed, and the surrounding facilities and operations. It has various meanings and ways of being computed depending upon its use. 3. Availability Classifications The definition of availability is somewhat flexible and is largely based on what types of downtimes one chooses to consider in the analysis.
What is Equipment Reliability and How Do You Get It? By Mike Sondalini and Howard Witt Abstract High equipment reliability is a choice and not an accident of fortune. To a great extent you can choose how long you want between equipment failures. You can deliver high equipment reliability
performance of BELT equipment. The present paper aims at reviewing the available pertinent literature in the subject field and deals with various aspects of performance measurement of BELT equipment in the mining industry. These indicators which are used for evaluating the performance of BELT equipment are described herewith.
Heavy Mobile Equipment Benchmark for Surface Mines (HME Benchmark) HME Benchmark allows users to select a machine and define its operating circumstances, generating a contextual estimate that details periodic maintenance costs, manpower requirements and machine availability .
Equipment Availability. Definition: "Equipment Utilization" measures the percentage of time a piece of equipment is actually operationally in a 24 hour day, for a given period of performance measurement is the productive time expressed as a percentage of the total time available. Responsibility: The reporting of Equipment Utilization is the responsibility of the Production Controller.
OEE for mining equipment OEE applications in mining industry differ from manufacturing industry. Therefore, it is necessary to develop equipment''s own classification framework for the losses, which should be associated with the components of availability, performance and quality [16]. The necessary data classification

Again, some examples are ...
Monitoring of realtime performance versus plan. One benefit of realtime data is knowing the state and location of every piece of equipment in a mining operation at every second—and, in particular, whether it is operating according to or outside of the plan.
What is TEEP? TEEP (Total Effective Equipment Performance) is a performance metric that provides insights as to the true capacity of your manufacturing operation. It takes account both Equipment Losses (as measured by OEE) and Schedule Losses (as measured by Utilization).. TEEP is calculated by multiplying four factors: Availability, Performance, Quality, and Utilization.

Consider asset utilization, as depicted in ... element will result in poor equipment performance, increased maintenance costs or both. For example, Work Identification systematically identifies the Right Work to be performed at the Right Time. Without
Measuring Reliability. ... actually have a much greater influence on equipment condition and therefore they also must be held accountable for that equipment''s reliable performance. The fact is that in actual practice when operations and maintenance are jointly responsible for equipment reliability the opportunity to improve is significantly ...
The degree to which a system, subsystem or equipment is in a specified operable and committable state at the start of a mission, when the mission is called for at an unknown, a random, time. Simply put, availability is the proportion of time a system is in a functioning condition. This is often described as a mission capable rate.

Influencing equipment performance through maintenance metrics: Successful sites use key measurements to improve availability. The primary deliverable for any mine maintenance organization is available hours that the operations department can use to meet its production goals. Performance in this area is reported in terms of availability.
Feb 22, 2019· Understanding the Difference Between Reliability and Availability. ... We can refine these definitions by considering the desired performance standards. Availability is an Operations parameter as, presumably, if the equipment is available 85% of the time, we are producing at 85% of the equipment''s technical limit. ...
