Time Study: Its a method to break down any activity in detail elements and measure the time of those elements with proper rating. It is generally used for determining standards and scope of method improvement.
Work Sampling : It is a technique to determine the utilisation of either a machine or workman. It saves time of work study person as he randomly keeps monitoring process rather than spending whole of his time.

Why need to study industrial engineering?
Industrial Engineering is a extended branch of Mechanical engineering but now stands a separate entity. It involves work study, method study, time study, optimization techniques, value engineering. It focuses on improving the way a work or job is done. If one wants to improve an activity, optimize an activity either by man or machine, Industrial Engineering tools offer solution.
What are micromotion study and memomotion study?
Micromotion Study Micromotion study, which was originated by Frank B. Gilbreth, is one of the most exacting forms of work analysis available for job improvement. It is an analysis technique making use of motion pictures (or videotape) taken at a constant and known speed. The film becomes a permanent record of both the method being used and the time consumed in doing the work. Although micromotion study formerly made use of motion pictures, very few companies today are using them. As indicated earlier, videotape equipment has been developed so extensively that it has virtually supplanted the use of the motion picture camera. Further it is so cheap and easy to use that it makes the older approach archaic. Micromotion study provides a valuable technique for making minute analyses of those operations that are short in cycle, contain rapid movements, and involve high production over a long period of time. Thus it is very useful in analyzing operations such as the sewing of garments, assembly of small parts and similar activities.
What is the role of a industrial engineer in garment company?
to avoid unnecessary use of sewing machines, reduce manpower , use of folders and attachment to make garment easily with quality, make R & D , time study for bulk production. Rama
What college can you go to become a certified interior designer?

You can research colleges and universities by name, or by programs of study, or by geographical location, size, or combinations of part or all of them etc. The site will provide you with a list of institutions based on your request. It will give you the schools background, accreditation, degree offerings, programs of study, entrance requirements, tuition and fees, room and board, athletic programs etc. and a link to each institutions official web page. Make sure the college or university has a regional accreditation (most important). Practice navigating this site. It will be well worth the time and effort.
What is slack time?
Time that Lacks rigor or strictness ! Time span where an event has to occur without affecting (increasing) the project duration.
When to apply sampling?
you can use sampling when your population under study is large, expensive and time time consuming to study.... in a nut shell, when studying entire population is expensive we go for sampling...
What is the definition of time sampling?
definition of time sampling
Q1what is work sampling and what are the advantages nad disadvantages of work sampling over time study?
Work sampling involves recording activities and fixed or random intervals, these activities may or may not be rated.Work sampling is good for measuring things occurring over longer periods like the working week (e.g. contingencies like small/infrequent delays). Time study is good for measuring individual operations and operators to establish standard minute values. Work sampling can also do this and is useful for measuring groups of operators / machines at a time.
What kind of errors arise in sampling?
sampling is a waste of time
Is it sampling time and sampling interval same?
Nope. Sampling time - is the amount of time it takes to obtain the sample. Sampling interval - is the period of time between samples. For example - it may take 10 seconds to obtain a sample. Obtaining a sample once a day is a sampling interval of 24 hours.
How do sampling methods effect the rigor of a study?
A sample needs to be random and if not a simple random sample of the whole population then a stratified random sample (there are different ways to stratify). Otherwise the study is a waste of time.
Advantages and disadvantages of simple random sampling?
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming
What is the instantaneous sampling?
Instantaneous sampling is one method used for sampling a continuous time signal into discrete time signal. This method is called as ideal or impulse sampling. In this method, we multiply a impulse function with the continuous time signal to be sampled. The output is instantaneously sampled signal.
What is the Different between sampling and quantization?
Sampling Discritizes in time Quantization discritizes in amplitude
Why do ecologists use sampling?
Ecologists use sampling to gather data about populations, communities, and ecosystems without needing to study every individual or element in a given area, which can be time-consuming and impractical. Sampling allows researchers to make inferences about larger populations based on a smaller, manageable subset. This method also helps minimize disturbance to the environment and provides a more efficient way to monitor changes over time. Ultimately, sampling enhances the accuracy and reliability of ecological studies.
How sampling is carried out in water?
Sampling in water typically involves collecting water from a specific location using sterile containers to avoid contamination. The process can include grab sampling, where a single sample is taken at a particular time, or composite sampling, where multiple samples are collected over a period and mixed. Sampling depth and location are chosen based on the study's objectives, such as assessing pollution levels or monitoring aquatic life. Proper techniques and protocols are followed to ensure accurate and representative results.
What is sampling and holding time?
sampling time is the number of samples per second taken from a continuous signal to make it discrete and holding time is the time between two samples..
