OLE also accounts for labor utilization. Understanding where downtime losses are coming from and the impact they have on production can reveal root causes—which can include machine downtime, material delays, or absenteeism—that delay a line startup. Calculation: Availability = Time operators are working productively / Time scheduled Example:
Performance: speed at which the Work Center runs as a percentage of its designed speed. Quality: Good Units produced as a percentage of the Total Units Started. It is commonly referred to as the first pass yield (FPY). To calculate the Total Effective Equipment Performance(TEEP), the OEE is multiplied by a fourth component:
The Standard Time is the product of three factors: Observed time: The time measured to complete the task. Performance rating factor: The number pace the person is working at. 90% is working slower than normal, 110% is working faster than normal, 100% is normal.
In lean manufacturing, machine operator efficiency (MOE) is the performance of an employee who operates industrial machinery. [1] The operator's efficiency is measured as the time spent producing product divided by the time the operator is on duty. [ 2 ]
In thermal engineering, exergy efficiency (also known as the second-law efficiency or rational efficiency) computes the effectiveness of a system relative to its performance in reversible conditions. It is defined as the ratio of the thermal efficiency of an actual system compared to an idealized or reversible version of the system for heat ...
The performance of a processor is the time it takes to execute a program: .This can be further broken down into three factors: [4] Selection of an instruction set architecture affects , whereas is largely determined by the manufacturing technology.
These equations govern the power, efficiencies and other factors that contribute to the design of turbomachines. With the help of these equations the head developed by a pump and the head utilised by a turbine can be easily determined. As the name suggests these equations were formulated by Leonhard Euler in the eighteenth century. [1]
Data envelopment analysis (DEA) is a nonparametric method in operations research and economics for the estimation of production frontiers. [1] DEA has been applied in a large range of fields including international banking, economic sustainability, police department operations, and logistical applications [2] [3] [4] Additionally, DEA has been used to assess the performance of natural language ...
