Industrial
Engineering: Industrial Engineering is a branch of engineering
which studies the design and operation of production and service systems and
the people who operate in these systems. Industrial engineering helps to
improve quality and productivity.
SMV: Standard minute value is the standard time, to complete any
given task by using best possible methods at standard level of performance.
TPT (Throughput time): Throughput
time is the time taken by particular volume of work to complete.
Work study: Work
study is the systematic examination of the methods of carrying on activities so as to improve the effective use of resources and to set up standards of performance for the activities being carried out.
Work Measurement:
Work measurement is the
application of techniques designed to establish the time for a qualified worker
to carry out a task at a defined rate of working.
Work Sampling: Work sampling is a method of finding the percentage
occurrence of a certain activity by statistical sampling and random
observations.
Qualified Worker: A
qualified worker is one who has acquired the skill, knowledge and other
attributes to carry out the work in hand to satisfactory standards of quantity,
quality and safety.
Time study: To
determine the time is should take for a qualified worker to perform a specific
task using a specified method by directly observing on operator.
Method study: Method study is the systematic recording & critical examination of ways of
doing thing in order to make improvements.
Observed Time: Time
recorded by observing on operator while he she is doing a task.
Loss time: Loss
time is the ineffective or useless time that spends on any activity which is
not a specified part of a job.
Performance: This
is a figure which we calculate after reducing the lost time out of the total
available time.
WIP: WIP is the number
of garments under production at a given time.
Time measurement: Time
measurement is the application of techniques designed to establish the time for
a qualified worker to carry out a task at a defined level of performance.
Rating: Rating is the
assessment of the workers rate of working relative to the observer’s concept of
the rate corresponding to standard rate.
Target: Target is the
amount of production which should be produced by an operator or a line that a
management desires.
Bottleneck: Which
are holding up production operations or a lengthy operation that consumes a
great deal of time.
Plan layout: Plan
layout is the special arrangement & configuration of departments, work
stations, & equipment used in the conversion process.
Different types of
allowances: Relaxation
allowance M/C delay allowance Contingency allowance
Operation
breakdown: In the
clothing industry operation breakdown is the separation of the making
operations so that garments can be made up quickly & cheaply using
available labor & machinery.
Production line
balancing: Production
line balancing is the allocation of the work to be done to the people available
to do it production line balancing is used.
Basic Pitch time: In industrial Engineering, Pitch time is a ratio of
total SAM of garment and number of operations to be set for the style.
Predetermined Time: A
predetermined time standard is a work measurement technique whereby times
established for basic human motions (classified according to the nature of the
motion and the conditions under which it is made) are used to build up the time
for a job at a defined level of performance.
