PREFACE

This edition replaces the last SITRA publication ‘How to

Assess Your Mill’s Productivity (Vol.48, No.4,

October 2003)’ authored by Mr.R.Rajamanickam,

Mr.R.Ranganathan and Ms.R.Suganthi. As the norms for

spinning as well as cone winding productivity have been

revised since the last publication, the conversion factors

have been reworked and given in the report. This

publication explains with illustrations, the method of

assessing the various productivity indices – both spinning

and cone winding – that are used in the SITRA

productivity surveys.

I. UP TO RING FRAMES

This section describes the method of assessing labour and machine productivity

up to ring frames. Briefly, the method consists in adjusting the various productivity

parameters to 40s count. A mill can compare its productivity between months and also

judge its performance against SITRA standard, regardless of the differences in the counts

being produced. The standards are fixed such that they reflect the productivity levels

being attained or excelled by the top 10% of the mills in the industry. The revised

SITRA standards for HOK and OHS are given in Table 1.

Notes:

1. Level of modernisation assumed is as follows: Chute feed blow room line, cards fitted with automatic can changer, automatic waste evacuation system and auto leveller, draw frames fitted with automatic can changer for 1st passage, draw frames fitted with automatic can changer and autoleveller for 2nd passage, high speed fly frames and long length ring frames.

2. For work assignments, ancillary operatives as well as production rates assumed in various departments, reference may be made to SITRA publication ‘Norms for Spinning Mills’, 2010 edition.

Page 6: Sitra Norms 2010

3. HOK for combers and preparatory tenters and maintenance operatives may be taken as 1.0 (40s count).

4. Throughout this publication, 40s or 40s count always refer to 40s cotton carded yarn, unless otherwise qualified. Also, the phrase ‘adjusted to’ or ‘conversion to’ or ‘standardised’ or ‘conversion’ are used interchangeably.

1. Definitions of various productivity parameters

Definitions of various productivity parameters that are covered in SITRA’s inter-

mill productivity surveys are given below:

HOK : Operative hours to produce 100 kg of yarn. Adjusted HOK

: The HOK is adjusted to a common count of 40s by multiplying the actual production in ring frames in different counts by relevant conversion factors. The production so converted is termed as ‘standardised production’. Thus the adjusted HOK is calculated from: Operative hours = x 100 ∑Count-wise standardised ring frame production in kg

Conversion factors for HOK

: The conversion factors are the ratios of the HOKs of individual count to that of 40s count under given conditions.

HOK for a given count = HOK for 40s count

The count-wise HOKs are estimated taking into account count-wise production rates, work assignments, etc., that correspond to those for the standard mill. The conversion factors are different for various categories of operatives and for 40s count, they are unity for all the categories of operatives. Another major practical advantage of this method is that it is not required to obtain a break-up of the operatives according to each count (For count-wise, raw material-wise and category-wise HOK conversion factors, refer Tables A and B).

Standard HOK

: HOK for 40s count under the specified conditions. The standard HOKs for different categories of operatives are given in Table 1 and the conditions under which they can be attained are given in the footnotes to this table. As can be seen, the total standard HOK up to ring frames is 12.

Page 7: Sitra Norms 2010

3

Composite productivity index (CPI)

: A measure of productivity calculated by expressing the standard total HOK of 12 as a percentage of a mill’s total actual HOK adjusted to 40s count. It reflects the effect of both labour and machine.

P : Production per spindle per shift of 8 hours (adjusted to 40s count)

in grams. The overall production per spindle in ring frames, adjusted to 40s count, can be obtained by using the conversion factors. ∑Count-wise standardised ring frame production in kg = x 1000 Total spindle shifts (of 8 hours each) corresponding to the above production

Conversion factors for P

: These conversion factors are the ratios of the standard production per spindle in 40s count to the standard production per spindle in the given count. 110 g = Std. prodn. per spl. per 8 hrs. (g) in the given count

(for count-wise and raw material-wise conversion factors, refer Tables A and B)

OHS : Number of operatives employed per 1000 spindles adjusted to 40s

count. P x HOK = , where HOK and P are adjusted to 40s count 800

OHSAM : OHS modified to allow for a valid comparison of a mill’s OHS with the standard OHS of 1.65 taking into account the deviation of the mill’s production per spindle from the standard production per spindle. 1.65 x OHS = [1.65 – 0.0065 (110-P)]

SH : A measure of spindle utilisation expressed in terms of number of hours worked per spindle per day. It is calculated by dividing the total spindle hours worked per day by the installed spindles. The spindle utilisation is also expressed as percentage. SH ie. x 100 24

MPI : A combined measure of production per spindle and spindle utilisation. It is calculated by expressing the product of production per spindle (P) adjusted to 40s count and spindle utilisation (SH) as a percentage of 2640 (110 x 24). The index would be reduced by one-seventh if the mill works for only 6 days a week. P x SH = x 100 110 x 24

2. Operatives considered for the productivity assessment up to ring frames

A mill’s HOK - overall as well as category-wise, production per spindle and other

productivity parameters up to ring frames can be assessed based on one month data with

respect to operatives engaged in various departments, ring frame production and spindle

shifts worked in all the counts.

Operatives

Operatives actually engaged in different departments irrespective of whether they are permanent, badli and temporary are considered. The categories of operatives to be included for the calculation of HOK are as follows:

Mixing attendants, machine tenters, doffers, interval relievers and ancillary operatives such as jobbers (maistries/overlookers), fitters, fitter helpers, machine cleaners, oilers, tape stitchers, roller coverers, top arm draft zone cleaners, sweepers and materials handlers (lap/sliver cans/ bobbins/cops/ waste).

The following categories of operatives are not considered for the productivity assessment:

Contaminants removers, operatives pertain to comber and its preparatory machines, electricals, generators, humidification plant and workshop workers, watch and ward, attenders, investigators, gardeners, hostel/guest house/quarters workers, dispensary workers, canteen/mess workers, drivers, sanitary workers, civil workers, etc.

a. Spindle utilisation [hours worked per spindle per day (SH)]

The first step in the estimation of spindle utilisation is to convert the spindles

worked in all the three shifts to 8 hour shift. If the duration of each shift is 8 hours and

the mill works the ring frames round the clock, then there is no need to convert the

spindle shifts to 8 hour shift.

The shift duration of the case study mill is; I shift: 8.5 hours; II shift: 8.5 hours;

III shift: 7 hours.

8.5 8.5 7 Total converted spindle shifts = 613870 x + 617850 x + 534105 x (of 8 hours each) 8 8 8 = 1776044

Page 11: Sitra Norms 2010

Total spindle shifts of 8 hours each x 8 SH = Installed spindles x working days 1776044 x 8 = = 21.78 21744 x 30

b. Production per spindle per 8 hours (P), adjusted to 40s count

42932 x 0.889 = x 1000 1776044

= 107.7 g

c. HOK, adjusted to 40s count

Estimation of operative hours

Total number of operative hours in different categories is estimated by

multiplying the number of operatives employed in different shifts with the respective

shift duration less 30 minutes (time for meals). For example, for the shift duration of 8.5

hours, to estimate the operative hours, the number of operatives who are actually

employed, are multiplied by 8.

In the case study mill, the operatives employed during the month in mixing and

blow room are as follows:

The operative hours for the remaining categories have also been estimated on the

above lines and the same are given in Table 5.

Standardised production

The count-wise, raw material-wise and category-wise HOK conversion factors are

given in Tables A and B. The ring frame production in different counts is multiplied by

the respective category-wise conversion factors and the sum is used to estimate category-

wise HOK.

d. Operatives per 1000 spindles (OHS)

HOK x P OHS = 800 17.0 x 107.7 = = 2.29 800

The OHS figures for different categories of operatives are given in Table 5.

Modified OHS (OHSAM)

From the definition of OHS given above, it follows that OHS is a function of

production per spindle (P), although for small deviations in the production per spindle,

say, less than 5%, the workers’ complement engaged in different departments can be

expected to remain practically unchanged. However, for any large increase in the

production per spindle, the OHS would increase significantly. This is because ring frame

doffers and preparatory departments’ operatives would require to be engaged

proportionately in larger numbers to cope with the higher volume of ring frame

production.

Page 14: Sitra Norms 2010

10

The OHSAM can be worked out from the expression:

OHSAM = (1.65 x OHS) / [1.65 - 0.0065 x (110 - P)]

For the example considered,

OHSAM = (1.65 x 2.29) / [1.65 - 0.0065 x (110 - 107.7)] = 2.31

II. CONE WINDING

The standard production per tenter in conventional cone winding and automatic cone winding for different counts are given in the ‘SITRA Norms for Spinning Mills, 7th Edition, 2010. The drums per tenter, machine efficiency, winding-on speed, breakage rates, cop contents and work load taken for estimating the standard production per tenter are also given in the publication.

1. Definitions of various productivity parameters

In cone winding, only tenter HOK is estimated. The ancillary workers such as maintenance workers, sweepers, jobbers and materials handlers are not considered for the HOK calculation. The term ‘operative’ used in this section also indicates tenter.
