Description

Technical Field

[0001] The present invention relates to a production management analysis method and a production management system, and in particular to a production management analysis method and a production management system based on a work order system. Background Art

[0002] When companies undergo digital transformation, they must implement data governance for important subject matter data, such as financial statements, inventory aging, and manufacturing overhead, to standardize data formats, verify data accuracy, and trace data sources, thereby establishing a comprehensive data governance system. For example, a company's data governance process can be developed based on the principles of the IBM Data Governance solution, with relevant processes or sub-processes. A work order management system creates and executes work orders based on work items to ensure that all necessary work is completed. However, work order information only confirms and tracks the completion of data governance processes and does not reflect the progress of data governance. For example, company managers or data governance end users cannot understand the overall time and cost of project topics. Without this time and cost analysis, effective data governance progress cannot be managed, leading to costs and data governance delays due to improper manpower allocation. It is also impossible to assess the completion time of new topics and the actual data governance costs to determine whether new topics are worthwhile, thus hindering the company's digital transformation progress. Therefore, existing technologies need improvement. Summary of the Invention

[0021] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a production management system 1 according to an embodiment of the present invention. The production management system 1 includes a work order processing device 10, a processing circuit 20, and a storage device 30. The work order processing device 10 is used to generate work orders and store the work orders in the storage device 30. Each work order includes a work order identifier and relevant information of a process. Each work order uniquely corresponds to a process. The process recorded in the work order may correspond to a topic, and the process is used to complete the tasks of the corresponding topic. Each topic may include at least one process. For example, the topic may be a data governance project topic, and the process is used to complete the tasks of the data governance project topic. The work order may include a work order identifier, work order status information, process information, and topic information. The work order identifier is used to identify the work order and is unique. The work order status information indicates the work order status. The work order status includes added (creating a work order), in progress, and completed (completing the work order). The order of changing the work order status is as follows: added → in progress → completed. In addition, other work order states between the Added and Completed states (e.g., Development, Verification, Review, etc., but not limited thereto) may also be included in the In Progress state. Process information may include a process identifier for a process documented in the work order and the work schedule for that process. The process identifier is used to identify the process documented in the work order. Subject information may include a subject identifier. The subject identifier is used to identify the subject corresponding to the process in the work order.

[0022] The work order processing device 10 can modify the work order status recorded in the work order according to the execution status of the process, and store the modified work order in the storage device 30 to replace the originally stored work order. Figure 2 As shown, the process corresponding to the work order with the work order identifier WO1 is process P1, and the subject corresponding to process P1 is subject S1. The work order processing device 10 creates a work order 200_1 (the work order identifier (identification, ID) is WO1), and the work order status recorded in the work order 200_1 is "newly added". After creating the work order 200_1 (the work order identifier ID is WO1), the work order processing device 10 stores the work order 200_1 in the storage device 30. When the process P1 begins to be executed, the work order processing device 10 changes the work order status from "newly added" to "in progress", and stores the modified work order 200_2 in the storage device 30. When the process P1 has been completed, the work order processing device 10 changes the work order status from "in progress" to "completed", and stores the modified work order 200_3 in the storage device 30. As Figure 2As shown, work orders 200_1, 200_2, and 200_3 are the same work order (with work order identifier WO1), and the work order statuses recorded in work orders 200_1, 200_2, and 200_3 are different. In one embodiment, the work order processing device 10 can generate work orders using Microsoft's List or Excel software, DevOps software, or Mantis software, and modify the work order status recorded in the work orders based on the execution status of the process, but is not limited to this.

[0023] Furthermore, since the processes documented in a work order can correspond to a topic, each topic can include multiple processes. In the production management system 1 , all processes within each topic can be recorded, and the execution order of all processes within each topic can be recorded to generate a process reference table. This process reference table can then be stored in the storage device 30 for subsequent access. For example, a process reference table can be generated and stored in the storage device 30 in accordance with IBM data governance process principles.

[0024] Please refer to Figure 3 , Figure 3 FIG3 is a schematic diagram of a process 3 according to an embodiment of the present invention. Process 3 includes the following steps:

[0025] Step S300: Start.

[0026] Step S302: Obtain a plurality of work orders at predetermined intervals, each work order corresponding to a process, and each work order including work order status information.

[0027] Step S304: When multiple work orders are obtained each time, the work order status and corresponding candidate status time of the multiple work orders are determined to generate a work order change form, wherein this step includes, for each work order, checking the work order status of the work order each time the work order is obtained, and determining the current time as a candidate status time corresponding to the work order status of the work order to record it in the work order change form.

[0028] Step S306: Determine the duration of the processes corresponding to the plurality of work orders according to the work order change form to generate a process duration form.

[0029] Step S308: Create a production management visualization chart based on the work order change form, the process duration form, and the process reference table.

[0030] Step S310: End.

[0031] According to process 3, in step S302. When the production management system 1 is operating, the work order processing device 10 can generate multiple work orders and store the multiple work orders in the storage device 30. In addition, the work order processing device 10 can modify the work order status recorded in the work order according to the execution status of the process and store the modified work order in the storage device 30. Each work order corresponds to a process, and each work order includes information on a work order status. The processing circuit 20 can access the multiple work orders stored in the storage device 30 at different times. For example, the processing circuit 20 accesses the multiple work orders stored in the storage device 30 at predetermined intervals to obtain and analyze the accessed multiple work orders.

[0032] In step S304, each time a plurality of work orders are obtained, the processing circuit 20 determines the work order status of the plurality of work orders and the corresponding candidate state time to generate a work order change form and stores the work order change form in the storage device 30. For example, for each work order, each time a work order is obtained, the processing circuit 20 checks the work order status of the work order, determines the current time as a candidate state time corresponding to the current work order status of the work order, and records the candidate state time in the work order change form. For example, Figure 2 As shown, the time points are sequentially as follows: T1 → T2 → T3 → T4 → T5. At time T1, the work order stored in storage device 30 with work order identifier WO1 is work order 200_2. At time T1, processing circuit 20 reads the work order with work order identifier WO1 (i.e., work order 200_2) from storage device 30 and determines that the work order status of work order 200_2 is in progress. Processing circuit 20 determines the current time (T1) as a candidate state time corresponding to the work order status (in progress) of the work order and records the work order status (in progress), the corresponding candidate state time (T1), the subject (subject identifier S1), and the process (process identifier P1) of the work order with work order identifier WO1 in the work order change sheet.

[0033] At times T2 and T3, since process P1 is still in progress, the work order stored in the storage device 30 with the work order identifier WO1 is still work order 200_2. In this case, at times T2 and T3, the processing circuit 20 accesses work order 200_2 from the storage device 30 and determines the current time at the time of access (T2 and T3) as the candidate state time corresponding to the work order status (in progress) of the work order. Similarly, at time T4, since process P1 has been completed, the work order processing device 10 has changed the work order status from "in progress" to "completed." At time T4, the work order stored in the storage device 30 with the work order identifier WO1 is work order 200_3. At time T4, the processing circuit 20 reads the work order with the work order identifier WO1 (i.e., work order 200_3) from the storage device 30 and determines that the work order status contained in work order 200_3 is completed. Processing circuit 20 determines the current time (T4) as a candidate state time corresponding to the work order's work order status (Complete) and records the relevant information in the work order change form. In other words, processing circuit 20 continuously accesses work order information from storage device 30 at different times, resulting in multiple candidate state times for each work order status within the same work order. The work order change form can record the time information of work order status changes. Furthermore, if the work order includes a timestamp information for the work order status, processing circuit 20 can also extract the timestamp information recorded in the work order to generate the work order change form.

[0034] On the other hand, since the processing circuit 20 continuously accesses the work order information in the storage device 30 at different times, each work order status in the same work order will have multiple corresponding candidate status times. The processing circuit 20 can perform a data cleaning procedure on the work order change form based on the work order status of multiple work orders. For each work order, the processing circuit 20 determines all candidate status times corresponding to the work order status of the work order as in progress from the work order change form, and retains the earliest candidate status time and the latest candidate status time corresponding to the work order status of the work order as in progress in the work order change form. For example, Figure 4 As shown, for the work order with the work order identifier WO1, all candidate time states corresponding to the work order status being in progress are T1, T2, and T3 respectively. The processing circuit 20 can retain the earliest candidate state time T1 and the latest candidate state time T3 corresponding to the work order status being in progress for the work order with the work order identifier WO1, and remove the candidate state time T2; for each work order, the processing circuit 20 determines all candidate state times corresponding to the work order status being completed from the work order change form, and retains the earliest candidate state time corresponding to the work order status being completed in the work order change form. For example, Figure 4As shown, for the work order with work order identifier WO1, all candidate time states corresponding to the work order status "in progress" are T4 and T5, respectively. The processing circuit 20 can retain the earliest candidate time state T4 corresponding to the work order status "in progress" for the work order with work order identifier WO1 and remove candidate time state T5 to implement a data cleansing process. This will facilitate faster and more accurate generation of the process duration table.

[0035] In step S306, the processing circuit 20 can access the work order change form in the storage device 30 and determine the process time of the processes corresponding to the multiple work orders based on the work order change form to generate a process time form. Since each work order uniquely corresponds to a process, the work order status of the work order can be used as the process status of the process recorded in the work order, and the candidate state time of the work order status can be used as the candidate state time of the process. For each process recorded in the work order, the processing circuit 20 determines the start time, end time, process time and whether the process is completed of the process of each work order based on the information in the work order change form. The processing circuit 20 determines the earliest candidate state time corresponding to each work order as the ongoing work order state from the work order change form, and determines the earliest candidate state time as the start time of the process corresponding to the work order. The processing circuit 20 determines whether there is relevant information in the work order change form that the work order state corresponding to the work order is completed. If the work order change form indicates that the work order status is Completed, the processing circuit 20 determines the candidate state time corresponding to the work order status being Completed as the final time of the process. If the work order change form indicates that the work order status is Completed, the processing circuit 20 determines the latest candidate state time corresponding to the work order status being In Progress as the final time of the process.

[0036] Next, the processing circuit 20 can calculate the length of time from the start time of the process to the end time of the process to obtain a duration of the process. For example, the processing circuit 20 can calculate the number of calendar days from the start time of the process to the end time to obtain a duration of the process. In a variant embodiment, the processing circuit 20 can calculate the number of working days from the start time to the end time of the process to obtain a duration of the process. In this way, the processing circuit 20 can record the topic ID of the topic corresponding to each work order process, the process ID of the process, the start time, the end time, the duration of the process, and whether the process is completed in a process history sheet and store the process history sheet in the storage device 30. The process history sheet records the time information of each process. Since each topic can include at least one process, all processes corresponding to a topic ID can be found in the process history sheet and relevant information of all processes corresponding to the topic ID of the topic can be retrieved for subsequent analysis.

[0037] In step S308, the processing circuit 20 creates a production management visualization chart based on the work order change form, the process history form, and the process reference table. Each topic includes multiple processes. For each topic, the processing circuit 20 can access the process reference table stored in the storage device 30 to determine all the processes of the topic. The processing circuit 20 can access the time information of all the processes of the topic in the process history form and calculate a topic idle ratio index of the topic based on it. For example, for each topic, the processing circuit 20 can access the process history table stored in the storage device 30, and extract the process time of each process corresponding to the topic in the process history table and calculate the sum of the process times of all the processes corresponding to the topic. The processing circuit 20 can extract the start time of all the processes corresponding to the topic in the process history table, and determine the earliest start time from the start time of all the processes corresponding to the topic as the start time of the topic. The processing circuit 20 can extract the final time of all processes corresponding to the subject in the process duration table, and determine the latest final time from the final time of all processes corresponding to the subject as the final time of the subject. The processing circuit 20 can calculate the number of calendar days between the start time of the subject and the final time of the subject to obtain an experienced number of days for the subject. In a variant embodiment, the processing circuit 20 can calculate the number of working days between the start time of the subject and the final time of the subject to obtain an experienced number of days for the subject. The processing circuit 20 calculates a subject idle ratio index based on the sum of the historical times of all processes corresponding to the subject and the experienced number of days. The processing circuit 20 can calculate the subject idle ratio index according to formula (1):

[0038] SIR n =(1-X n / Y n )×100%(1)

[0039] Among them, SIR n represents the topic idleness ratio index of the nth topic, X n represents the sum of the process times of all processes of the nth topic, Y n Indicates the number of days experienced by the nth subject.

[0040] For each topic, the Topic Idle Ratio Index reflects the percentage of days during which no performers were working on the work order or process. A lower Topic Idle Ratio Index indicates a higher labor cost in terms of time spent, while a higher Topic Idle Ratio Index indicates a higher time cost.

[0041] Furthermore, the processing circuit 20 can access the work order change form stored in the storage device 30 to determine the status information of the last process of each subject to determine whether the last process of the subject has been completed. In one embodiment, the production management visualization chart includes a subject production management chart. The processing circuit 20 can establish a subject production management chart based on the subject idle ratio index, the number of days, the start time, the final time and the status information of the last trip of all subjects, and visually display the subject production management chart. In this way, the idle situation during the execution of the subject process can be provided and the corresponding overall execution situation can be quickly and clearly grasped. For example, please refer to Figure 5 , Figure 5 Schematic diagram of a theme production management diagram based on theme idle ratio index according to an embodiment of the present invention. Figure 5 As shown, each horizontal bar represents the execution status of the data governance process of a subject. The starting point of the horizontal bar represents the start time of the subject, and the end point of the horizontal bar represents the final time of the subject. The text C in the horizontal bar indicates that the data governance process of the subject is completed (the process status is completed), and the text P in the horizontal bar indicates that the data governance process of the subject is in progress (the process status is in progress). The numbers shown in the horizontal bar represent the number of days (calendar days) experienced by the subject, and the background color pattern of the horizontal bar represents the value of the idle ratio index of the subject. For example, taking the subject at the circle marked with number 500 as an example, this subject is a subject that has completed the data governance process, and its number of days (calendar days) experienced is 386 days. Not only is the number of days experienced longer than other subjects, but the proportion of time that the subject spends on data governance is idle. Therefore, the total human cost of this subject will be higher than that of other subjects.

[0042] In a variant embodiment, the production management visualization chart includes a theme relative production management chart. For each theme, the processing circuit 20 can calculate the percentile of the theme idle ratio index of the theme in the theme idle ratio index of all themes to obtain a theme idle relative index of the theme. In this way, the processing circuit 20 can establish a theme relative production management chart based on the theme idle relative index, the number of days, the start time, the end time and the status information of the last trip of all themes and visualize the theme production management chart based on the theme idle relative index. For example, please continue to refer to Figure 5 , the background color of the horizontal bar can be changed to represent the relative index of topic idleness, so as to indicate the relative situation of the idle status of different topics. The topic idleness relative index generated based on the topic idleness ratio index is a cost comparison between different topics. By converting the topic idleness ratio index of all topics into percentiles, topics with more abnormal idleness can be filtered out. In a mature process, the time and labor costs of each topic will be similar. If the idle status of the most abnormal topic is within an acceptable range, it means that the overall data governance process is in a healthy state. Therefore, by using the topic idleness relative index of an embodiment of the present invention to find the topics with the lowest and highest indexes and perform a difference comparison, it can be understood whether the current process is a mature process.

[0043] In one embodiment, the production management visualization chart includes a process time cost analysis chart. For each topic, the processing circuit 20 can access the process reference table stored in the storage device 30 to determine all the processes of the topic. For each topic, the processing circuit 20 can access the process history table stored in the storage device 30 and extract the process history time of each process corresponding to the topic in the process history table. The processing circuit 20 can establish a process time cost analysis chart based on the processes of all topics and the process history time, and visually display the process time cost analysis chart. For example, please refer to Figure 6 , Figure 6 FIG. 1 is a schematic diagram of a time cost analysis diagram of a process according to an embodiment of the present invention. Figure 6 As shown, each horizontal bar represents the process of a theme, and the background color pattern of the horizontal bar represents the process time. Figure 6 The process time cost analysis chart allows managers to evaluate the time cost distribution of each process. For example, the subject corresponding to process 1.3 takes more time, while the subject corresponding to process 3.3 takes less time. In comparison, process 1.3 is a process that takes more time. Therefore, when there are new subjects to be prepared for data governance, managers know that process 1.3 will take more time than process 3.3. As the number of data governance subjects increases, such as Figure 6As more and more data is used, the accuracy of the estimated time for process work orders for new topics will be strengthened, making the production management of data governance processes more mature.
