[0001] The present invention relates to the technical field of Gantt chart data processing, and in particular to a steelmaking Gantt chart plan intelligent updating method and system based on a time calculation model. Background Art

[0002] Gantt chart, also known as bar chart, is a bar chart that shows the internal relationship between projects, schedules and other time-related system progress over time. In the steelmaking scheduling and production planning, the Gantt chart presents the steelmaking plan in two dimensions: time and unit. At the same time, it can display some conventional data according to user needs. In terms of component design, it has good openness and scalability, and can customize information presentation according to different management needs. It provides a variety of plan editing auxiliary functions, simplifies the plan editing method, and improves the efficiency and accuracy of plan management.

[0003] At present, the traditional method of updating the steelmaking Gantt chart plan is manual refresh. Under dynamic abnormal conditions, there is a situation where the plan display and actual performance do not match.

[0032] Other features, objects and advantages of the present invention will become more apparent from the detailed description of non-limiting embodiments made with reference to the following drawings:

[0033] Figure 1It is a structural schematic diagram of the steelmaking Gantt chart plan intelligent update system based on the time calculation model of the present invention;

[0034] Figure 2 A schematic flow chart showing the processing logic details of updating the steelmaking Gantt chart plan for the time extrapolation model of the present invention; DETAILED DESCRIPTION

[0035] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0036] After the steelmaking scheduling plan is saved and issued, the present invention regularly updates the plan information on the Gantt chart panel through an intelligent time calculation method, so that planners can track the real-time situation of the plan operation and update the plan signals that have been produced in real time. At the same time, for the plans that have not been produced, the reasonable production rhythm of the plans can be timely calculated according to the current production requirements, so as to realize dynamic, timely and accurate updating of the plans.

[0037] Embodiment 1

[0038] According to the present invention, a steelmaking Gantt chart plan intelligent updating method based on a time calculation model is provided. Figure 1 and Figure 2 As shown, including:

[0039] Step S1: Obtain the current steelmaking Gantt chart plan. The acquisition method includes obtaining the current Gantt chart plan information by querying the database, and the plan information is converted into data in the format required for plan update after being processed by the program and cached in the plan data set.

[0040] Step S2: Determine whether the steelmaking Gantt chart plan is in the editing state. If so, only query the database performance information and update the information of the performance part according to the performance information; if not, execute step S3.

[0041] Step S3: When updating, the overall update is performed, the actual performance part is updated and displayed according to the actual performance information, and the plan part is updated and displayed according to the plan information through the time calculation model. The step S3 includes:

[0042] Step S3.1: Determine whether the unit is currently in production based on the actual performance start time and the planned end time. If so, execute step S3.2; if not, determine whether the planned start time of the first furnace of the unproduced furnace of the unit is greater than the time of the current time axis. If so, the unproduced furnace of the unit does not move backward along the time axis; if not, the planned start time of the first furnace of the unproduced furnace of the unit is equal to the current time axis time, and all unproduced furnaces of the unit move backward along the time axis. Specifically, determine whether the unit is currently in production when there is a furnace of the unit that has a production performance start time but no production performance end time, and the current time is greater than or equal to the production performance start time, and less than or equal to the planned end time of the furnace.

[0043] Step S3.2: Determine whether the subsequent process of the current unit's planned furnace has actual performance. If so, no optimization update is performed; if not, determine whether the furnace has an actual production end time. If so, no optimization update is performed; if not, execute step S3.3. Among them, the process information of the furnace can be locked by the manufacturing order number. The manufacturing order number can be used to lock the process, process plan and actual performance information of the furnace, and then determine whether there is actual performance.

[0044] Step S3.3: Read the current planned end time of the furnace, compare it with the current time of the system to determine whether the planned end time of the furnace is less than the current time. If not, no optimization update is performed; if so, the planned end time of the furnace is modified to the time of the current time axis, and moves backward following the time axis.

[0045] Further, the steelmaking Gantt chart plan intelligent updating method of the present invention is specifically described as follows in conjunction with the accompanying drawings:

[0046] For the Gantt chart plan, it is distinguished whether the current plan is in the editing or unedited state. For the plan in the unedited state, the whole plan is updated when updating, the actual performance part is displayed according to the actual performance, and the plan part is updated and displayed through the time calculation logic; if the plan is in the editing state, only the database actual performance information is queried, and the actual performance change value is partially updated. In order to prevent the loss of plan editing information, the plan information in the Gantt chart remains unchanged for the unproduced plan information, and the actual performance is updated according to the operation signal. For example, when the operation signal of the production start and end of a certain process is uploaded for the scheduled furnace, the actual production start and end time of the furnace in the process is updated according to the operation signal.

[0047] For the planning information time calculation and update logic, first determine the unit production status:

[0048] When one furnace is in production at the current unit: the production start time of the subsequent unproduced furnace is greater than the current time axis time, and the unproduced furnace of the unit does not move backward along the time axis; the furnace before the currently producing furnace is an unproduced furnace, and the planned start time of the previous furnace is less than the start time of the furnace in production. The planned start time of the previous furnace must be equal to the time axis and move backward along the time axis; the production start time of the subsequent unproduced furnace is less than or equal to the current time axis time, and the start time of the first furnace of the subsequent unproduced furnace of the unit is equal to the current time axis time and moves backward along the time axis;

[0049] The current unit is not in production: the planned start time of the first furnace of the unproduced furnace of the unit is greater than the time of the current timeline, and the unproduced furnace of the unit does not move backward along the timeline; the planned start time of the first furnace of the unproduced furnace of the unit is less than or equal to the time of the current timeline, the production start time of the first furnace of the unproduced furnace of the unit is equal to the current timeline time, and all unproduced furnaces of the unit move backward along the timeline.

[0050] Then determine the status of the furnace on the planning panel: if there are actual results in other subsequent processes of the furnace, the furnace is considered to have been completed in the process, that is, the process is displayed according to the database planning information, and the planning information is considered to be the actual results, and the planned information of the furnace will not be changed; if a furnace has an actual production end time but no actual production start time, the furnace also needs to be treated as a completed furnace, and the default planned start time is the actual production end time.
