    Definitions Related ro Productivity

    Productivity is the ratio of output to some or all of the resources used to produce the output.

    Types of productivity

    We can mention the following types of partial productivities:
    · Labor productivity: units produced / hours worked
    · Capital productivity: output / capital input
    · Material productivity: output /material input

    What is the productivity index?

    We can calculate a type of partial productivity as labor productivity as output per man hours for a complete year. These figures obtained from year to year can be indexed and can be related to a base year so that output per man our comparisons can be made.

    Definition of total productivity

    It is the ratio of tangible output and tangible input.
    Differences among partial productivity, total factor productivity and total productivity
    Men, materials, machines, methods, money, energy, etc. are inputs.

    · Partial productivity: output / one class of input
    · Total factor productivity: net output / (labor + capital)
    · Total productivity : sum of all tangible outputs / sum of all tangible inputs

    Industrial engineering functions

    Industrial engineering plays an important role in any organization. Organizations are usually set up with selected industrial engineering functions best suited to their requirements. For example a company manufacturing standardized products may not have operation research functions whereas a manufacturer of precision instruments may heavily rely on quality control functions.

    Traditionally, industrial engineering involves different functions, which support manufacturing and service operations in order to improve productivity, safety and workers welfare. These functions, as in the past, are otherwise neglected by many entrepreneurs who are only motivated by profit. Developed countries have long ago realized the physiological needs of their citizens as their life style has improved with the abundance of material resources. Further, with an increase in educated workers, the demand for improved working conditions and better treatment from the owners of enterprises increased. The owners adopted many of the industrial engineering functions to satisfy the employees demand while still maintaining profitability.

    Industrial engineering functions can be grouped in different ways to suit an organization’s need. The major groupings, which provide a profile of its involvement, are:

    · Methods engineering
    · Work measurement
    · Planning of facilities and handling of materials
    · Statistical quality control
    · Production planning and control
    · Operations analysis and computer simulation
    · Human resources
    · Safety at work
    · Equipment engineering
    · Advanced concepts and strategies
