What is Standard Minute Value (SMV)?



Definition: SMV means standard minute value. Time taken by a standard operator to complete any given operation with pre-determine conditions.


Standard Minute is the time value arrived at for a task based on the average rate of output which qualified workers will naturally achieve without over exertion provided that they know and adhere to the specified method and provided that they are motivated to apply themselves to their work.

SMV= Basic time + Allowance



What is IE?



·    Industrial Engineering is a branch of engineering dealing with the optimization at complex processes or systems. It is especially concerned with the optimization of man, machine, materials, equipment’s and how to utilize these resources in better method and in proper way to enhance productivity and quality of work.

 

An IE is responsible to design a way to produce a product in a quicker, easier and in better method.



What is Method study?

Method study: Method study is the systematic recording & critical analysis of ways of doing a job so as to make improvements it analyzes how a work is being done currently to find out ways to improve so that productivity increases. Method study discovers suitable and easier method of work so that the task can be completed quickly.





7 Steps of Method Study:-

1.    Select: Select the job to be study.

2.    Record: Record the all of relevant fact by direct observation.

3.    Examine: Examine the data/facts critically and in sequence.

4.    Develop: Develop the most practical, ergonomic & economic method.

5.    Define: Define the new method in detail.

6.    Install: Install the method as standard and train the operator to use it.

7.    Maintain: Maintain the new method by regular routine check.


What is Work Study?

Definition: A Systematic examination and development of operational method and standards to enhance productivity and quality of work.

How to Calculate Production Capacity of a Factory?

In garment Industry, “Production capacity” is one of the most important play role used for vendor source by the buyers. Buyer can easily understand the order capacity of the vendor. And, they allocate order proportionally to the vendor. So it is very important that marketing and planning personnel should aware about the production capacity of their production units. After read this article anyone can easily understand how to calculate the production capacity of a factory?

According to production planner express the capacity of a factory in terms of how many machines they have. And also calculate the production of a particular style produce in a day. Capacity of a factory is primarily expressed in terms of total machines factory have According to the style category, machine requirement can be change and daily average production output can also change.

A factory’s capacity is express in the terms of total minutes or hours or production per day.

  • Factory capacity in hours
  • SAM of a Product.
  • Line efficiency (Average).
  1. Calculation of a factory capacity (Hr):

Generally, need to know total machines of a factory & production runs of a day.

Let,

Total Number of machines=300

Production run of a day=10 hours

So, total factory capacity (in hours) = 300*10 hours = 3000 hours

  1. Calculation of a Product Standard Average Minute (SAM):

According to industrial Engineer calculate SAM of a particular style.

Let,

The SAM of a particular style is 30 minutes.

  1. Factory Average Efficiency%:

According to Industrial Engineering department can understand the historical data or calculate   average line efficiency.

Let,

The style average line efficiency is 70%.

Calculation of production capacity of a factory (Pcs):

Now, we can use following formula to calculate production capacity.

Production capacity (pcs) = {(Capacity in hours*60/product SAM)}*line efficiency

 Example: Let, a factory has 10 sewing lines and each line has 30 machines. Factory Production runs 10 hours per day. If factory is producing only one style (Shirt) of SAM 30 minutes and used daily production capacity at 70%.What is the production capacity of that factory?

Total machine=10 linesX30 Machines=300 Machines

Total Hour=300 Machines X 10 hours=3000 hours

Total Minutes=3000 hoursX60 Minutes=180000 Min. (1 hour=60 Minutes)

SAM=30 Minutes

Average line efficiency=70%

Production capacity (pcs) = {(Capacity in hours*60/product SAM)}*line efficiency

= (3000*60/30
= 180000/30 min.
= 6000*0.70(Line efficiency)

=4200 pcs

So, Production Capacity of a day =4200 Pcs(shirt)

Please note that Production will vary according to the line efficiency and initial days production line efficiency is lower & it will faster when start full flow of production.

Most important formula for Textile Industrial Engineering

 

Most important formula for Textile Industrial Engineering


Industrial Engineers are the heart of production based industry at present time. An industry grows up for the hard-working dedicated engineers who do everything for the industry. Because he is the mastermind person for the industry and planned how to do better and better from today to tomorrow. 


1.  Standard minute value 

SMV = Basic time + (Basic time × Allowance) 

           SMV (Standard Minute Value) = Basic Time  Allowance of Basic Time 

 = (Cycle Time  Rating of Operator)  Allowance of Basic Time

                                                                =Cycle time X rating (1+Allowance %)


 

2. Basic time  

Basic time = Observed time × Rating 

3.  Observed time 

Observed time = Total Cycle time / No. of cycle

4. Cycle Time 

Cycle Time = 60 /  Target 

5. Rating 

Rating = (Observed Rating × Standard rating) / Standard rating 

6. Available

Available minute = Work hour × Manpower 

7. Capacity 

Capacity = 60 / Capacity time in minute 

8. Capacity Achievable 

Capacity Achievable = Capacity × Balance 

9. Factory capacity 

Factory capacity = (Work hour / SMV) × Total worker × Working day × Efficiency 

10. Target setup for a line

Target = {(Total manpower per line × Total working min per day )/ S.A.M.} × 100

11. Required no. of the operator 

Required no of operator = Target daily output / Daily output per operator 

12. Daily output 

Daily output = Work hour / SMV 

13. Efficiency 

Efficiency = (Earn minute × Available minute) × 100

14. Earn minute 

Earn minute = No of Pc’s (Production) × Garments SMV

15. General sweing data

GSD = (Man power × Work hour) / Target
