Abstract: Knowledge held by persons is accumulated by using a computer, and any person visually searches for the knowledge and utilizes a result of the search to continuously accumulate new knowledge, so that accurate, efficient work is implemented. Various types of knowledge are accumulated by describing knowledge held by persons in a coordinate system of 2D data or 3D data produced by digital techniques by using a method of a feature point representing a location of the knowledge by using a geometric shape or a position of a coordinate of the coordinate system.

Abstract: A quality control system comprises servers connected to companies having different quality control in-house systems and interconnected through networks and client devices operated by quality control managers belonging to the respective companies. In this quality control system, when the client device of one company logs in a server, according to the definition of the one company as a master and the definition of the customer company (step S1), definition of QPP data including quality information of the one company, product structure information, and production process information (step S2), definition of association of the QPP data of the one company and the customer company (step S3), and integration of the information defined at steps S2, S3(step S4), a quality control information chain linking the companies is formed.

Abstract: The invention provides a technology capable of calculating task time of for assembling a part.

Abstract: The invention vigorously supports a process of allocating tasks numbering several thousand to units numbering several hundred and allows a streamlined task assignment to be obtained in a short time.

Abstract: In order to obtain an index which generally shows the work burden extent of various works carried out in an automobile assembling factory or the like, for each work content, the maximum muscle contraction ratio is measured after the work has been continued for 5 seconds, the work burden index (L) is calculated from the measured ratio value, and the equivalent work burden in a standard work is calculated from the calculated work burden index (L) for 5 seconds. The work burden index (TVAL) of actual work is calculated from the equivalent work burden and the actual work time. Suitably, a work routine plan is corrected such that the obtained TVAL is normalized with an apparatus comprising means for storing the equivalent work burden for each work content, means for displaying an image of the work content, and means for inputting work content parameter and so forth while watching the displayed image.
