What is idle time and what are its causes?

Generally idle time means that time for which the employer pays, but from which he obtains no production. Otherwise it is the difference between the time for which workers are paid but the workers do not work. So it is a loss to the organisation. It can be minimized but, cannot be controlled during idle time, the workers remain due and contribute nothing towards production. It is the difference between actual hour and actual hour worked. There are two types of idle times:

  1. Normal idle time: The normal idle time is that idle time which cannot be fully avoided but effective effort should be made to reduce it.
  2. Abnormal idle time: Abnormal idle time arises due to various causes which can be avoided. Abnormal idle time can be avoided if proper precautions are taken. Thus the factors which are responsible for controlling and avoiding idle time must be taken care of.

Normal idle time is permitted but abnormal idle time should be avoided.

ANSWER:

Idle time indicates that time for which wages are paid to the workers but no production is obtained during that time. Following are the causes of idle time:

- Due to machine break down

- Power failures

- Waiting for instructions

- Waiting for tools or raw materials to start the production

- Economic Causes includes: Seasonal, cyclical or industrial nature

this is unproductive time spent by employees due to factors beyond their control

The above explanation is true as far as an industry or business centre is concerned.

The true definition of idle time is the time utilized for non productive action. This has of two effects. One is useful effect, as certain engines/machines/equipments are advised to run a particular time idle immediately after its first start of a day, before putting in to full pludged utilization. To attain certain safe operating condition an idle time running is essential. The second is counter productive idle time which financially, ethically, functionally and ideologically negative to its envisaged scope.

Do you need to plug in a diesel engine?

diesel need not have a spark plug to ignite, just high compression will heat it up since its density is higher than of normal petrol or gasoline. gasoline having a lower density needs can't heat up well after compression and thus needs a spark to ignite it. You may need to plug in the block heater depending on the outside temperature Some older trucks need to be plugged in if the temperature is near freezing.

What are the uses of white cement?

What is D gear?

In vehicles with an automatic transmission, the letter D often denotes the driveposition, as opposed to N (for neutral), R (for reverse) or P (for park).

What is the Equation for finding G-force of a spinning object?

Say I have a ring that is of "R" radius and I need "X" number of Gs on the side of the ring.

how do I find how fast it needs to go?

What is an American tool post?

An American style tool post is a square tool post designed for a center lathe. It can be rotated, is square and dove-tailed on all four sides. The dove tails allow tool holders with cutting tools clamped in it to be inserted and locked in place. This style of tool post decreases production time due to its ease of function and preset tool center heights.

What are the best pre med universities in upstate ny?

How does a stealth plane works?

Stealth technology was invented about ten seconds after radar. There are several approaches to making a craft invisible to radar: 1) Absorbing the beam: This is what the microwave absorber patches on popcorn bags do to heat up their oil. But more sophisticated materials are layered on the vehicle's skins. It is even possible to etch "reflective-holograms of empty space" onto aluminum or stainless steel. Projected electron beams have been used but the technology is complicated. 2) Deflecting the beam: This was a Russian invention that the Lockheed Skunkworks people found and used to build stealth aircraft (F117). If reflecting surfaces don't allow the radar beam to return to the receiver...they can't detect the airplane. The airplanes look a little strange, but computers fly them well. 3) Passing the beam: Some materials just pass microwaves with little reflection or absorption. This is not practical for large structures.

How is the term six figures defined?

We see or hear this term in several places. One might refer to the amount of money someone makes or that something costs. The "six figure" number is one that has six digits. There are a number of them, but the first one is 100,000 and it comes right after the last five figure number, 99,999. The last six figure number is, of course, 999,999, which is just before 1,000,000. Now that we have that out of the way, let's jump. The term is tossed out there usually to indicate that something just breaks into the hundred thousand units range. We need examples. "He graduated from college and went to work pulling down six figures in his first year." That's an example of the "threshold" use meaning that the person specified started working for a bit over $100,000 per year. Here's another example that is similar. "The website was so popular that hits in the first year went into the six figure range." There were over 100,000 hits on the site in the first year. But there is another use other than the "near" end of the scale. Let's look at the other end of the six figure range. "The darn building project for the new church extension rocketed over budget and went into the high six figures." There's a suggestion here that the project mentioned cost something roughly in the $700,000 to $900,000 range or anywhere in there. That's the "high six figures" we mentioned. "Foot traffic in the new mall went into the high six figures in the first six months they were open." The number of people in the mall is being expressed here, and the ball park figure is 700,000 or a bit less, or on up to 800,000 or a bit more. The "high six figures" here is a chunk under a million, but not close enough to say "nearly a million" and be "clear" about it. And what about mid six figures? That around 500,000 or about half a million. We usually call that "half a mill" for short. Sometimes it's hard to be "specific" about something so "general" in nature.

How many feet are in 1 degree of latitude?

One degree of latitude is 69.06 miles. With this information, and knowing that there are 5,280 feet in a mile, this becomes a simple arithmetic problem.

What do you mean by lean six sigma?

Lean is a body of knowledge and tools organizations use to remove all non-value-added time and activity (more simply waste) from their processes. Whether you work for a government agency, small business, large corporation, hospital, or whatever it maybe, your company exists to provide value to customers. You may feel that the term customer may not be appropriate for a hospital or a government agency, nonetheless, the term customer refers to that broad category of people who utilize the services. So, practically speaking, the patient is the customer for a hospital.

For some, Lean is a set of methods and tools for improving a process. For others, Lean is an improvement system, like the Toyota Production System, that sets the framework for how the whole enterprise operates. As much as Lean is a tool used to improve processes, it's also a philosophy and system by which to run an organization or company.

While all organizations are different, they are all the same in that they exist to fulfill some human or societal need. In fulfilling that need, all organizations take a certain set of inputs and transform them into certain outputs, called "products," "services," "transactions," etc. A school, for example, takes curriculum and course materials and, through the functions of teaching and administration, injects this knowledge into students' heads. At least that's what's supposed to happen, with the students' help!

Where can you find a bridge rectifier?

Bridge rectifiers are used in alternators and other electronic equipment that needs full DC current and can be bought at local electronic stores as well as the internet. Radio shack sells them also. A bridge rectifier is a 2 or 4 rectifiers that rectify AC current into DC. A full wave bridge usually consists of 4 diodes that rectify both the negative and positive swings of the AC current into DC. With the proper center wound transformer, only 2 diodes are needed.

Search Google for a "full wave rectifier" diagram!!!
