How to apply lean six sigma in a thermal power plant? I have tried something but I need for help to identify the different points.

Being at a thermal power plant, you may explore following areas.

• The electric efficiency of a conventional thermal power station, considered as saleable energy (in MWe) produced at the plant busbars as a percent of the heating value of the fuel consumed, is typically 33% to 48% efficient. Improvement in this efficiency could be an objective of a Six Sigma Black Belt project.
  

• Improvement in waste heat utilization (cogeneration) can be another project.
  

• If freshwater production and electricity are co-products, then the objective of enhancement of these could be taken up as Six Sigma projects.
  

• Since the efficiency of the plant is fundamentally limited by the ratio of the absolute temperatures of the steam at turbine input and output, efficiency improvements require use of higher temperature, and therefore higher pressure, steam. Ensuring consistency in high temp and resulting high pressure could be taken up as Six Sigma project as well.
  

Maintenance improvement in terms of the following are additional projects

• Improving OEE (Overall Equipment Effectiveness)
  

• Reducing MTTR (Mean Time to Repair)
  

• Increasing MTBF (Mean Time between Failures)

Please can you inform me about how to applied six sigma in healthcare sector .

thanks

Hi Mr Hamdani,

Reproduced below is an extract of the response by VK sir on this forum to a similar question as yours, by one of the participants in the past.

Hope, the same answers your question.

Thanks & rgds.

Example of Six Sigma projects in Healthcare - the following types of Six Sigma projects are being carried out in the healthcare sector :-

• Improving patient and relative feedback
  
• Reducing or eliminating invoicing errors
  
• Reducing patient checkout time.
  
• Reducing patient complaints
  
• Reducing complaint resolution time
  
• Control spending over time
  
• Reducing admitting delays
  
• Reducing medicine administration errors
  
• Reducing medication delays
  
• Improving bed utilization
  
• Increasing number of surgical operations per week.
  

Many thanks for this information , I would like to study this field .

also machine capabily(equipment capability can be considered as process performanace.

Thermal efficiency is also considered as one of the main criteria in power plant maintenance.

Role of six sigma in capacity based management in Thermal power plant ???

Hi. Mohini,

Lean Six Sigma is a set of approaches that is used for business improvement. It commonly follows a DMAIC cycle and is a systematic sequence of problem solving. If you reword your question to highlight a business problem in a power plant, I shall be able to provide a more specific reply.
