1. A production management system for a production unit for which a schedule of tasks to be accomplished is set up and stored in a memory in a central management device, the system comprising:
- individual electronic devices each associated with an operator;
control stations comprising a computer and a control screen;
an operation screen displaying the schedule of tasks to be accomplished by a plurality of operators and being visible to each of the plurality of operators; and
a network linking the individual electronic devices, the operation screen, and the control stations to the central management device, whereintasks accomplished and problems encountered during an implementation of the tasks by the operator are input by a respective operator into each of the individual electronic devices and transmitted to the central management device,the central management device compares data inputted into the individual electronic devices by the operators and the schedule of tasks to be accomplished,the central management device generates a warning when the central management device detects a discrepancy based on the comparison between the data inputted by the operators and the schedule of tasks to be accomplished that exceeds a predetermined and memorized threshold, and transmits the warning to the individual electronic devices, the operation screen, and the control stations,at least a part of the individual electronic devices, the operation screen, and the control stations display the warning involving the respective operator associated with one of the individual electronic devices and other operators,the operation screen displays a two-dimensional graph of the schedule of tasks, and a variable scale is used for one axis of the graph in which successive values incrementing the one axis are not equally distributed,the variable scale is used for a time axis and present tasks are displayed larger than tasks performed in the past or future, andsides of the variable scale are compressed based on a logarithmic function.

Abstract
A production unit for which a schedule of tasks is to be accomplished is prepared and stored in a central management device. The unit includes individual electronic devices, control stations, and a network linking the individual electronic devices and the control stations to the central management device. Each individual electronic device includes a device to input the tasks accomplished and problems encountered and further includes a transmission device for information input. The central management device compares data received with the schedule of tasks, generates a warning signal when the comparison detects a gap or discrepancy between the data received and the schedule of tasks, and transmits the warning signal to the individual electronic devices and control stations. The individual electronic devices and the control stations include a device to display the warning signal.

13. A production management system for a production unit for which a schedule of tasks to be accomplished is set up and stored in a memory in a central management device, the system comprising:
-
individual electronic devices each associated with an operator;
control stations comprising a computer and a control screen;an operation screen displaying the schedule of tasks to be accomplished by a plurality of operators and being visible to each of the plurality of operators; and a network linking the individual electronic devices, the operation screen, and the control stations to the central management device, wherein tasks accomplished and problems encountered during an implementation of the tasks by the operator are input by a respective operator into each of the individual electronic devices and transmitted to the central management device, the central management device compares data inputted into the individual electronic devices by the operators and the schedule of tasks to be accomplished, the central management device generates a warning when the central management device detects a delay based on the comparison between the data inputted by the operators and the schedule of tasks to be accomplished that exceeds a predetermined and memorized threshold, and transmits the warning to the individual electronic devices, the operation screen, and the control stations, at least a part of the individual electronic devices, the operation screen, and the control stations display the warning involving the respective operator associated with one of the individual electronic devices and other operators, the operation screen displays a two-dimensional graph of the schedule of tasks, and a variable scale is used for one axis of the graph, the variable scale is larger in a center of the screen and smaller towards edges of the screen such that tasks performed during an entire duration of the scale are all displayed on the operation screen, the variable scale is used for a time axis, the edges of the variable scale are compressed based on a logarithmic function, the control stations belong to at least two levels of a production hierarchy, and a warning generated at one level of the hierarchy is forwarded by the system to a higher or lower level of the hierarchy. - View Dependent Claims (14)
