  • Publication number: 20110276162
    Abstract: Disclosed are a device, a system, and a method for setting standard work times that take real-world manufacturing capabilities into account. Provided is a standard work time calculation device (10), which analyzes fluctuations in production line assessment indices on a per time period basis, and computes standard work times for each region, as classified according to the degree of fluctuation. The standard work time calculation device (10) comprises a fluctuation coefficient computation unit (111), which computes coefficients of fluctuation for the assessment indices, a fluctuation region identification unit (112), which identifies regions of fluctuation with coefficients of fluctuation that are greater than or equal to predetermined thresholds, and a standard work time computation unit (113), which computes standard work times for regions of fluctuation.

  • Publication number: 20110254663
    Abstract: Although techniques for determining the positions of workers and products and displaying their tracks on a two-dimensional layout were available in the past, they were inconvenient in that work times and process shifts over time could not be grasped. A technique for grasping work contents of a worker highly accurately utilizing electronic tags was also available. However, it was also inconvenient in that the workers had to read the electronic tags intentionally while at work. The work information processor (100) is capable of showing passage of time and process shifts by specifying steps at given points in time by a position sensor (161) attached to a worker.
