productivity benchmarking in spinning mills
TRANSCRIPT
Productivity Benchmarking-Goals Key Performance Indicators Reference Stds-PB Few Case Studies Route Map for PB Use of ERP
Manufacturing Excellence will be the Result of
Productivity Benchmarking
Market supremacy can be achieved only and only if
Organizations Excel in all their Performance Metrics
Honda City and Maruti
Park Dale mills used 2000 employees in 1980 to produce 1 lac kg per week
In 2014 the same volume is produced with 140 employees
When all mills find it difficult to cross 145 gps in Modern Ringframes in 40s Combed Hosiery, one group of mills in South broke the barrier and achieved 175 gps using Compact systems
Compact spindleage shoot up in southern mills, by Commercial exploitation
When Spg mills were at stress to achieve 5% profit margin one mill in Tamil Nadu consistently reported 10% profit for more than 5 years with Permanent employees.
It is only because of its ` No. 1` position in Combed Compact Weaving yarn Market with a command on Premium
When Mills were struggling to achieve imperfections below 70 in 30s CH with 74% YR, one mills near Dharapuram consistently achieved less than 50 imperfections with an YR of 77% and stood first in Export yarn Quality
Efforts taken :Ginning is controlled by them
Reduce Manufacturing Cost Better Use of Assets Top Quality &Efficiency (RFT) On time Delivery Service level Excellence Control on Inventory levels
Higher production per spindle(gps) Higher productivity per
employee(kg/employee or HOK) Higher yields(YR) Less energy to produce(Units per kg) Control on Consumables Control on Packing Cost
Utilisation Efficiency/Break up of Losses
Maintenance Repairs Traveller changes Lot changes Unscheduled power related stoppages
Build the required Quality into the product
Relate In process Q to final process Q
ZDQC-Zero Defect Quality Control
Identify potential failure points and plug it
Ratio of Actual no of days taken to deliver
to Committed no of days to deliver the lot

FMEA-Failure Mode Effect Analysis
Can help the mills to reduce Breakdowns to near zero.
YR can be increased by controls on Waste monitoring from Blow room itself.
Each Zone has the task of `specific type of waste` removal

Power spent on compressor has been brought down from 4.1% to 3.4% by plugging Airleakages in Lap preparation in Comber Department and also in Autoconer
RH is displayed in broad &visible letters in Autoconers/Spinning departments.Shopfloor has been educated on Humidification plant efficient running
Ukg is brought down to 4 and being improved further.
Mills Current level-74% Count pattern -Medium SC and C Target planned -3% improvement
Improved areasCard waste Zonewise analysis revealed SFD
waste is abnormally high at the level of 2%.Reduced to 0.5%
Hard Waste was found to be abnormal due to poor work practices in RF.Retrained the workforce and reduced the hard waste from 0.9 to 0.6%
In Semicombed Variety mills has not done Conditioning.Effectively restarted.
Sweepings found to be 0.8%-Unusually high.On checking it is a mixture of Usable waste and Sweeps.Educated the sweepers and concerned department tenters.Reduced the same to 0.5% level
Finally the mills is able to exceed its expected target of 3 and achieved 3.5%.
Final YR -77.5%
Monitoring & Maintaining Moisture content in Mixing and outgoing yarn
Monitoring and Maintaining Moisture content in Saleable waste
Strict monitoring and control of AWES waste level by visual checks in Compactors-weekly
Tare weight control in Packing Weighment of Mixing at the time of Laying Ensuring 65 to 70 % in Packing department
Empowered Employee Beliefs and Attitudes Belongingness of Employees
Any reward/incentive/benefit system must be focussed on `Self development of Employees towards empowering him`so that he becomes `Mouth piece` for our units.
Education on Systems available to all employees through all channels of Communication
Short and brief meetings at villages where our Employees are concentrated
`We are thrilled by news that 160 employees are graduated in one group of Mills.One employee in that group Joined TCS too.`
Training and Retraining of Employees play a vital role in realising our ME/PB Goals
If Training system needs to be effective, Employee Retention is the Keyword
Data Collection plays a vital role in system towards Manfacturing excellence
Direct transmission of data without any manual intervention needs to be ensured wherever it is possible
One time entry and Precise data are the basis of ERP implementation
NVA`s must be eliminated at all levels of Hierarchy through ERP
Availability of Reports as Structured
Develop Alert Sytems
Deviation Levels to be attacked then and there
SWOT analysis Create Management Vision and Mission
Break up of Mission into Performance Objectives
Develop Suitable and Effective Performance linked Wage structure
Mock Implementation and Nodal wage increase-Communicate to employees and get feedback
Apply suitable corrections and Implement
Review periodically and revise targets in comparison to Benchmarked levels
Develop Customer Satisfaction Index
Implement essential pillars of TPM
Use Techniques of FMEA for reduction of Breakdowns in Machines and Quality
Training and Retraining of Employees with proper Communication tools
for Retention form the foundation of any System towards
MANUFACTURING EXCELLENCEThrough
PRODUCTIVITY BENCHMARKING
