What is productivity in operation management?
Productivity is defined as a total output per one unit of a total input. In control management, productivity is a measure of how efficiently a process runs and how effectively it uses resources. Output is simply the rate of which goods are being produced and readied for sale.
How do you measure productivity in operations?
It is computed as a ratio of outputs (goods and services) to inputs (labor and materials). The more productive a company is, the better it uses its resources. The equation is as follows: Productivity = output/input.
How is productivity calculated in BPO?
The call center productivity formula is:
- (Total Output / Total Input) x 100 = Labor Productivity.
- 6.5 / 8 = .8125 x 100 = 81.25% productive.
- (Abandoned Calls / Total Incoming Calls) x 100 = Abandonment Rate.
- (Total Talk Time + After-Call Work Time) / Total Number of Calls = Average Handle Time.
What is the formula of productivity?
You can measure employee productivity with the labor productivity equation: total output / total input. Let’s say your company generated $80,000 worth of goods or services (output) utilizing 1,500 labor hours (input). To calculate your company’s labor productivity, you would divide 80,000 by 1,500, which equals 53.
What is the formula of efficiency?
Efficiency is often measured as the ratio of useful output to total input, which can be expressed with the mathematical formula r=P/C, where P is the amount of useful output (“product”) produced per the amount C (“cost”) of resources consumed.
What is the SI unit of efficiency?
The term efficiency is a dimensionless measure (sometimes quoted in percent), and strictly heat rate is dimensionless as well, but often written as energy per energy in relevant units. In SI-units it is joule per joule, but often also expressed as joule/kilowatt hour or British thermal units/kWh.
How do you calculate energy from frequency?
E = h * c / λ = h * f ,
- E is the energy of a photon.
- h is the Planck constant,
- c is the speed of light,
- λ is the wavelength of a photon,
- f is the frequency of a photon.
What is the dimensional formula of energy?
Derivation. Or, E = [M] × [L1 T-1]2 = M1 L2 T-2. Therefore, energy is dimensionally represented as M1 L2 T-2.
What is the dimensional formula of work?
Or, W = [M1 L1 T-2] × [M0 L1 T0] = [M1 L2 T-2]. Therefore, work is dimensionally represented as [M1 L2 T-2].
What is dimensional formula of frequency?
| Frequency | |
|---|---|
| Other units | Baud (Bd) cycles per second (cps) revolutions per minute (rpm or r/min) solar neutrino unit (SNU) |
| In SI base units | s−1 |
| Derivations from other quantities | f = 1 ∕ T |
| Dimension | |
What is the dimensional formula of mass?
When a physical quantity X depends on base dimensions M(Mass), L(Length) and T(Time), Temperature, current electricity, luminous intensity and amount of substance with respective powers a, b and c, its dimensional formula is represented as [MaLbTc].
What is dimensional formula of density?
Therefore, density is dimensionally represented as [M1 L-3 T0].
What are the 7 fundamental dimensions?
In total, there are seven primary dimensions. Primary (sometimes called basic) dimensions are defined as independent or fundamental dimensions, from which other dimensions can be obtained. The primary dimensions are: mass, length, time, temperature, electric current, amount of light, and amount of matter.
What is the dimensional formula of viscosity?
Or, η = [M1 L1 T-2] × [M0 L2 T0]-1 × [M0 L1 T-1]-1 × [M0 L1 T0] = [M1 L-1 T-1]. Therefore, viscosity is dimensionally represented as [M1 L-1 T-1].
What is the SI unit of viscosity?
The SI unit for kinematic viscosity is square meters per second (m2/s). However, due to the viscosity values of most common fluids, square centimeters per second (cm2/s) is used more often. Note that 1 cm2/s is equivalent to 100 cSt.
What is unit of viscosity?
The unit of viscosity, accordingly, is newton-second per square metre, which is usually expressed as pascal-second in SI units. The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature.
What is the dimensional formula of stress?
Therefore, stress is dimensionally represented as [M1 L-1 T-2].
What is SI unit of stress?
This means stress is newtons per square meter, or N/m2. However, stress has its own SI unit, called the pascal. 1 pascal (symbol Pa) is equal to 1 N/m2. In Imperial units, stress is measured in pound-force per square inch, which is often shortened to “psi”. The dimension of stress is the same as that of pressure.
What is dimensional formula of surface tension?
Surface Tension (T) = Force × Length-1. Or, T = [M1 L1 T-2] × [L-1] = M1 T-2. Therefore, surface tension is dimensionally represented as M1 T-2.
What is the dimensional formula of moment of inertia?
Or, MOI = [M1 L0 T0] × [M0 L1 T0]2 = M1 L2 T0. Therefore, the moment of inertia is dimensionally represented as M1 L2 T0.
Why do we calculate moment of inertia?
Moment of inertia of a body about an axis gives the measure of resistance offered by the body when it is subjected to rotation about that axis. And more is the moment of inertia then more is the resistance offered by the body towards rotation.
What is the dimensional formula of radius of gyration?
So finally, the dimensional formula of the radius of gyration will be written as: [M0LT0]. The power of zero on the dimension of the mass and time shows that the mass and the time dimensions are zero for the radius of gyration. So, the correct answer is “Option C”.
What is the SI unit of radius of gyration?
meter
What is the dimensional formula of height?
Explanation: Height x breadth x length x dimension = mass. 1 x 1 x 1 x 1 = 1.18
What is dimensions and dimensional formula?
DIMENSIONS are the powers to which the fundamental quantities are raised to represent other physical quantities. DIMENSIONAL FORMULA is an expression in which dimensions of a physical quantity is represented in terms of fundamental quantities.30
How do you calculate dimensions?
Measure any two sides (length, width or height) of an object or surface in order to get a two-dimensional measurement. For example, a rectangle that has a width of 3 feet and height of 4 feet is a two-dimensional measurement. The dimensions of the rectangle would then be stated as 3 ft. (width) x 4 ft.
