Description

Technical Field

[0001] The present application relates to the technical field of project process management optimization, and more specifically, to an enterprise project management optimization method and system based on an AOE network. Background Art

[0002] In project time management, the effectiveness of project time management can be improved by determining the critical path method (CPM) of the project's subprojects. The subprojects on the critical path have zero slack time (SlackTime), that is, the implementation of these subprojects cannot be delayed. Previous research has already developed a number of algorithms for determining the critical path of subproject implementation in project management, such as the exhaustive method for calculating the critical path of project management, the adjacency matrix calculation method of the activity network diagram, and the seven-grid diagram method.

[0003] In modern project management, the AOE (Activity On Edge) network is often used to describe and analyze a project. When using the AOE network for project analysis, once the duration of each sub-project is determined in the AOE network diagram of the construction project, the critical path can be calculated based on the time of each activity defined on the AOE network diagram. In actual projects, the completion time of sub-projects is often not static and may be affected by various factors, such as insufficient resources and changing requirements. Relying on static AOE network diagrams to calculate the critical path may lose actual accuracy. Summary of the Invention

[0030] In actual projects, the completion time of sub-projects is often not static and may be affected by various factors, such as insufficient resources, changes in demand, etc. Relying on the static AOE network diagram method to calculate the critical path may lose actual accuracy.

[0031] Based on the above reasons, an embodiment of the present application provides an enterprise project management optimization method based on an AOE network, which includes: constructing an AOE network diagram for project management, determining the earliest start time, latest start time and floating time of each unstarted sub-project at the current moment according to the AOE network diagram through a critical path algorithm, and determining the critical path of the AOE network diagram, wherein the earliest start time and the latest start time of each unstarted sub-project in the critical path are the same; wherein the AOE network diagram includes multiple nodes connected by multiple edges, each edge connects two nodes to represent the dependency relationship between the sub-projects corresponding to the two nodes, one node corresponds to one sub-project, and the attributes of the first node include the duration of the first sub-project ; Divide the duration of the project into multiple project time periods that are continuous and non-overlapping in time sequence, determine the project time period to which each unstarted sub-project belongs, obtain the number of dependent projects for each unstarted sub-project, and determine the unstarted sub-project with the least number of dependent projects in each project time period as an alternative sub-project; when the first unstarted sub-project in the critical path is delayed, obtain a second alternative sub-project in a second project time period subsequent to the first project time period to which the first unstarted sub-project belongs, and adjust the project resources in the first project time period to start the second alternative sub-project; and adjust the project resources in the second project time period to speed up the second unstarted sub-project in the critical path in the second project time period. The method in the embodiment of the present application can monitor the completion time of the sub-projects in each project time period after determining the critical path of the AOE network diagram. After the sub-projects in the project time period are delayed, the project resources in the sub-projects can be adjusted in time to adjust the sub-projects, and sufficient project resources can be provided to the subsequent sub-projects on the critical path to ensure the completion time of the sub-projects in the critical path, thereby ensuring the completion time of the entire project.

[0032] In some scenarios, an enterprise project management optimization method based on AOE network in an embodiment of the present application can be applied to various types of enterprise project management such as construction project management and software development project management, and can improve the management effect of the completion time of enterprise projects.

[0033] The following is a detailed description of an enterprise project management optimization method based on an AOE network provided in an embodiment of the present application with reference to specific examples.

[0034] Figure 1 A flow chart of an enterprise project management optimization method based on AOE network provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the method includes S110 to S130, and S110 to S130 are described in detail below.

[0035] S110: Construct an AOE network diagram for project management. Using a critical path algorithm, determine the earliest start time, latest start time, and float time of each unstarted subproject at the current moment based on the AOE network diagram. Also, determine a critical path for the AOE network diagram, where the earliest start time and latest start time of each unstarted subproject in the critical path are the same. The AOE network diagram includes multiple nodes connected by multiple edges, where each edge connects two nodes to represent a dependency relationship between subprojects corresponding to the two nodes. One node corresponds to one subproject, and the attributes of the first node include the duration of the first subproject.

[0036] Taking a civil engineering construction project as an example, when working, the embodiment of the present application can first construct an AOE network diagram for project management. Figure 2 A schematic diagram of an AOE network diagram provided in an embodiment of the present application is shown as follows: Figure 2 As shown, the AOE network diagram includes multiple nodes connected by multiple edges, each edge connecting 2 nodes to represent the dependency relationship between the sub-projects corresponding to the 2 nodes, and the dependency relationship between the sub-projects corresponding to the 2 nodes indicates that the start of the sub-project corresponding to the subsequent node needs to rely on the completion of the sub-project corresponding to the previous node. 1 node corresponds to 1 sub-project, and the attributes of the first node include the duration of the first sub-project. In the AOE network diagram, the start of a sub-project is usually based on the dependency relationship with the previous sub-project, and there are also some sub-projects that do not need to rely on the previous sub-project. The AOE network diagram is used to represent the dependency relationship between sub-projects to help plan and manage the schedule of the entire project.

[0037] For example, Figure 2As shown in the AOE network diagram, each circle represents a sub-project. The attributes T1, T2, and T3 on the circle represent the duration of the sub-project. The arrows between the circles represent the dependencies between sub-projects. The startup of a sub-project is usually based on the dependency on the previous sub-project. There are also some sub-projects that do not need to depend on the previous sub-projects.

[0038] For example, the conditions of the critical path algorithm can be set as follows: in the form of "head-directed edge-tail", the weight of the directed edge is the time required for the project corresponding to the original vertex. In the AOE network diagram, the starting point and end point of the AOE network diagram can be predetermined based on the actual project. Sub-projects that do not depend on previous sub-projects can be defined as sub-projects of lower importance. Sub-projects that do not depend on previous sub-projects can then be discarded in the AOE network diagram, and the critical path can be determined by discarding sub-projects that do not depend on previous sub-projects.

[0039] After obtaining the AOE network diagram, the critical path algorithm can be used to determine the earliest start time, latest start time and floating time of each unstarted sub-project at the current moment based on the AOE network diagram, and determine the critical path of the AOE network diagram. The earliest start time and latest start time of each unstarted sub-project in the critical path are the same.

[0040] In an AOE network graph, directed edges between original vertices can be retained, meaning the tail of the original predecessor points back to the head of the original vertex. These directed edges have a weight of 0. Vertices are denoted Vi (i = 1, 2, 3, ...) in topological order. Topological sorting ensures that the predecessors of any vertex are always numbered lower, and the successors are always numbered higher, thus ensuring that the AOE network graph has only one starting and ending point.

[0041] When executing the critical path algorithm, the edge can be recorded as a k (k=1,2,3,…), the corresponding weight is w(k); and the earliest start time and the latest start time of vertex Vi are ve(i) and vl(i), respectively, and the edge a k The earliest start time and the latest start time are e(k) and l(k). k Corresponding e(k)=l(k), then a k Represents key activities.

[0042] The calculation process of the critical path algorithm is as follows:

[0043] (1) Let ve(1) = 0;

[0044] (2) Traverse all vertices in topological order and set ve(j) = max{ve(i) + w(k)} (Vi is the predecessor vertex of Vj and ak is associated with both).

[0045] (3) Make the latest start time of the endpoint equal to its earliest start time;

[0046] (4) Traverse all previous vertices in reverse topological sorting, and set vl(i) = min{vl(j) - w(k)} (Vj is the successor vertex of Vi and ak is associated with both);

[0047] (5) For any given edge a k , if its head and tail are Vi and Vj respectively, then let e(k)=ve(i), l(k)=vl(j)-w(k).

[0048] Through the above critical path algorithm, the earliest start time and the latest start time of all activities can be calculated. All critical paths can be obtained by applying the depth-first search (DFS) algorithm to all key activities.

[0049] Figure 3 A schematic diagram of a critical path obtained by an enterprise project management optimization method based on an AOE network provided in an embodiment of the present application is shown as follows: Figure 3 As shown, taking the civil engineering construction project as an example, Figure 3 The AOE network diagram is part of the entire construction project. Through the AOE network diagram, the critical path can be determined, including the substation installation subproject, traction power supply project subproject, contact network installation subproject, single-machine debugging subproject and system debugging subproject.

[0050] like Figure 3 As shown, after determining that the critical path includes the substation installation subproject, traction power supply project subproject, contact network installation subproject, single-machine debugging subproject and system debugging subproject, it can be determined that there are multiple subprojects such as the ring network installation subproject, opposite-side access subproject, and evacuation platform installation subproject.

[0051] S120. Divide the duration of the project into multiple project time periods that are continuous and non-overlapping in time sequence, determine the project time period to which each unstarted sub-project belongs, obtain the number of dependent projects of each unstarted sub-project, and determine the unstarted sub-project with the least number of dependent projects in each project time period as an alternative sub-project.

[0052] like Figure 3 As shown, after obtaining the critical path of the AOE network diagram, the duration of the project can be divided into multiple project time periods that are continuous and non-overlapping in time sequence, and then time delay management and project resource principles can be performed on multiple sub-projects within multiple project time periods. Project resources include human and material resources used to promote project resources.

[0053] For example, Figure 3As shown, when the duration of the project is divided into multiple project time periods that are continuous and non-overlapping in time sequence, it can be specifically divided into three stages: day 0 to day 5, day 5 to day 10, and day 10 to day 15.

[0054] After obtaining multiple project time periods, the project time period to which each unstarted sub-project belongs can be determined, and the number of dependent projects of each unstarted sub-project can be obtained. Then, the unstarted sub-project with the least number of dependent projects can be determined within each project time period. The unstarted sub-project with the least number of dependent projects can be individually adjusted as an alternative sub-project, so that each project time period can have a corresponding unstarted sub-project as an alternative sub-project.

[0055] It should be noted that the number of dependent projects of the alternative sub-project corresponding to each project time period can be 0, 1 or 2. The embodiment of the present application does not limit the number of dependent projects of the alternative sub-project corresponding to each project time period.

[0056] It should be noted that the number of alternative sub-projects corresponding to each project time period may be 1, 2 or 3, and the embodiment of the present application does not limit the number of alternative sub-projects corresponding to each project time period.

[0057] S130. When a delay occurs in a first unstarted subproject on the critical path, obtain a second candidate subproject in a second project time period subsequent to the first project time period to which the first unstarted subproject belongs. Adjust project resources in the first project time period to start the second candidate subproject. Adjust project resources in the second project time period to expedite the second unstarted subproject on the critical path in the second project time period.

[0058] When managing project time, when the first unstarted sub-project in the critical path is delayed, it means that the progress of the first unstarted sub-project may be affected by the previous unstarted sub-project and delayed, or it may be that the first unstarted sub-project is delayed due to multiple factors during the progress process.

[0059] After the first unstarted subproject is delayed, a second alternative subproject in a second project time period subsequent to the first project time period to which the first unstarted subproject belongs can be obtained. Then, within the first project time period, project resources can be adjusted to start the second alternative subproject, thereby achieving early start of the second alternative subproject within the first project time period to adjust the project progress.

[0060] For example, Figure 3As shown, the first unstarted subproject may be the substation installation subproject, the first project time period corresponding to the first unstarted subproject may be the project time period corresponding to day 0 to day 5, the second project time period may be the project time period corresponding to day 5 to day 10, and the second alternative subproject may be the main substation line project. When the substation installation subproject is delayed, the project resources may be adjusted within the project time period corresponding to day 0 to day 5 to start the main substation line project in the project time period corresponding to day 5 to day 10.

[0061] By adjusting the project resources to start the second alternative sub-project within the first project time period, the project resources required to advance the second alternative sub-project within the second project time period are correspondingly reduced. Therefore, the project resources can be adjusted within the second project time period to speed up the second unstarted sub-project in the critical path within the second project time period to improve the execution speed of the second unstarted sub-project in the critical path within the second project time period.

[0062] For example, project resources may include human resources and material resources.

[0063] The beneficial effect brought about by the above implementation method is that by monitoring the project progress of the sub-projects in the critical path in the AOE network diagram, when the first unstarted sub-project in the critical path is delayed, the project resources are adjusted to speed up the second unstarted sub-project in the critical path, thereby achieving the advancement of the sub-projects in the critical path of the entire project and improving the project's time management effect.

[0064] The beneficial effect brought about by the above-mentioned implementation method is that when the first unstarted sub-project in the critical path is delayed, the project resources are adjusted within the first project time period to which the first unstarted sub-project belongs to start the second alternative sub-project within the second project time period subsequent to the first project time period, so that the project resources can be reasonably allocated to ensure the progress of the sub-projects in the critical path.

[0065] In some implementations, adjusting project resources to initiate the second candidate subproject within the first project time period includes determining a first project resource index for adjusting project resources to initiate the second candidate subproject within the first project time period, wherein the first project resource index includes a total number of man-hours.

[0066] When adjusting project resources, a reasonable amount of project resource adjustment is determined to improve the effectiveness of the project resource adjustment. During the first project time period, a first project resource index for adjusting project resources to initiate the second candidate subproject can be determined. The first project resource index represents the total amount of project resources adjusted to initiate the second candidate subproject.

[0067] For example, the first project resource index may include the total number of manpower hours, which may be obtained by adding up the working hours of all staff members.

[0068] Adjusting project resources to expedite a second unstarted sub-project in a critical path within the second project time period, during the second project time period, includes adjusting project resources according to the first project resource index to expedite a second unstarted sub-project in the critical path within the second project time period, during the second project time period.

[0069] During the second project time period, when adjusting the second unstarted sub-project in the critical path within the second project time period, the project resources can be adjusted according to the first project resource index to speed up the second unstarted sub-project in the critical path within the second project time period, so that the total amount of project resources adjusted for starting the second alternative sub-project is the same as the total amount of project resources used to speed up the second unstarted sub-project in the critical path within the second project time period, thereby ensuring that the total amount of project resources for the entire project remains stable without the need for additional project resource investment.

[0070] The beneficial effect brought about by the above-mentioned implementation method is that the total amount of project resources adjusted for starting the second alternative sub-project is the same as the total amount of project resources used to speed up the second unstarted sub-project in the critical path within the second project time period. The progress of the sub-projects in the critical path can be guaranteed without the need for additional project resource investment, thereby ensuring the progress of the entire construction project.

[0071] In some implementations, adjusting project resources to initiate the second candidate subproject within the first project time period further includes determining a project resource index for the first unstarted subproject on the critical path that is delayed as the first project resource index, wherein the project resource index includes a total number of man-hours.

[0072] When determining the first project resource index, the project resource index of the first unstarted subproject in the critical path that is delayed can be determined as the first project resource index, and then the project resources can be adjusted based on the first project resource index to start the project resource index of the second alternative subproject.

[0073] For example, when determining the project resource index of the first unstarted subproject in the critical path that is delayed, the project resource index required to advance the portion of the first unstarted subproject in the critical path that is delayed can be calculated as the first project resource index.

[0074] For example, the project resource index may include the total number of manpower hours, which may be obtained by adding up the working hours of all staff members.

[0075] The beneficial effect brought about by the above implementation method is that by calculating the project resource index required to advance the delayed part of the first unstarted sub-project in the critical path as the first project resource index, and adjusting the project resources according to the first project resource index to start the project resource index of the second alternative sub-project, the stability of the total amount of project resources is ensured, which facilitates efficient management of project implementation.

[0076] The beneficial effect brought about by the above-mentioned implementation method is that by calculating the project resource index required for the delayed part of the first unstarted sub-project in the critical path, the project resource index required for the delayed part of the first unstarted sub-project corresponds to the project resources that are not effectively utilized. As the total amount of project resources for the second unstarted sub-project in the critical path within the second project time period, the stability of the total amount of project resources can be ensured, which facilitates efficient management of project implementation.

[0077] The beneficial effect brought about by the above implementation method is that the total number of project resources is evaluated by the total number of man-hours, which facilitates project resource management by man-hours and improves the convenience of project resource management.

[0078] In some implementations, dividing the duration of the project into multiple project time periods that are continuous and non-overlapping in time sequence includes: obtaining a project resource index for each unstarted sub-project, and dividing the duration of the project into multiple project time periods that are continuous and non-overlapping in time sequence based on an average value of the project resource index.

[0079] When dividing the project time periods, the project resource index of each unstarted sub-project can be obtained. The project resource index can be the total number of man-hours, and the project time periods can be reasonably divided according to the project resource index.

[0080] When dividing the project time periods, the project duration can be divided into multiple project time periods that are continuous and non-overlapping in time sequence according to the average value of the project resource index, that is, the project resource indexes in multiple project time periods are roughly the same.

[0081] For example, Figure 3 As shown, the project resource index of each subproject, such as the substation installation subproject, traction power supply project subproject, contact network installation subproject, single-machine debugging subproject, system debugging subproject, ring network installation subproject, opposite-side access subproject, and evacuation platform installation subproject, can be determined. When the duration of the project is divided into multiple project time periods that are continuous and non-overlapping in time sequence, the spanning time periods of each project time period can be reasonably allocated to ensure that the sum of the project resource indices of the subprojects in each project time period is roughly the same.

[0082] For example, the project time periods can be reallocated to Day 0-Day 8, Day 8-Day 12, and Day 12-Day 15, respectively. The project resource indices in the three project time periods of Day 0-Day 8, Day 8-Day 12, and Day 12-Day 15 are roughly equal, and different sub-projects can be allocated to different project time periods according to the project resource indices, so as to facilitate subsequent adjustments to the sub-projects in the project time periods.

[0083] The beneficial effect brought about by the above implementation method is that different sub-projects are evenly distributed to different project time periods according to the project resource index, so that when the start time of the sub-projects in different project time periods is adjusted, the total amount of project resource index corresponding to the sub-projects in different project time periods can be ensured to remain stable.

[0084] The beneficial effect brought about by the above-mentioned implementation method is that by keeping the total amount of project resource indexes corresponding to sub-projects in different project time periods stable, and subsequently calculating the project resource index required to advance the delayed part of the first unstarted sub-project in the critical path, and using it as the total amount of project resources to accelerate the second unstarted sub-project in the critical path in the second project time period, the total amount of project resource indexes in different project time periods can be guaranteed to be stable, thereby avoiding an imbalance of project resources corresponding to the project resource indexes in different project time periods during project management and reducing the difficulty of project management.

[0085] Figure 4 The flowchart of the second enterprise project management optimization method based on AOE network provided in the embodiment of the present application is as follows: Figure 4 As shown, the above method further includes S210 to S220, and S210 to S220 are described in detail below.

[0086] S210: Obtain a progress status of a second candidate subproject within a time period of the first project, and determine a second delay probability value of the second candidate subproject according to the progress status of the second candidate subproject.

[0087] When the first unstarted subproject in the critical path is delayed, after starting the second alternative subproject within the first project time period, the delay probability of the second alternative subproject can be judged to facilitate the time management effect of the entire project.

[0088] During work, the progress status of the second alternative subproject within the first project time period can be obtained, and the second delay probability value of the second alternative subproject can be determined based on the progress status of the second alternative subproject. Then, the progress of the construction project can be adjusted in advance based on the second delay probability value of the second alternative subproject.

[0089] For example, when determining the second delay probability value of the second candidate subproject according to the progress status of the second candidate subproject, the project indicator corresponding to the progress status of the second candidate subproject may be analyzed and determined.

[0090] S220. When the second delay probability value is greater than the preset delay probability value, obtain a third alternative subproject in a third project time period subsequent to the second project time period, and adjust project resources in the second project time period to start the third alternative subproject; in the third project time period, adjust project resources to speed up the third unstarted subproject in the critical path in the third project time period.

[0091] After obtaining the second delay probability value, when the second delay probability value is greater than the preset delay probability value, it indicates that the second alternative sub-project may be delayed. After the second alternative sub-project is delayed, the project resources occupied by the second alternative sub-project are difficult to be used to speed up the second unstarted sub-project in the critical path within the second project time period, thereby causing the second unstarted sub-project in the critical path within the second project time period to be delayed accordingly.

[0092] When the second alternative subproject is likely to be delayed, a third alternative subproject in a third project time period subsequent to the second project time period can be obtained, and then the project resources can be adjusted within the second project time period to start the third alternative subproject, so as to advance the implementation of the third alternative subproject in the third project time period to the second project time period; accordingly, within the third project time period, since the third alternative subproject in the third project time period has been started in advance, sufficient room for project resource allocation has been reserved for the third project time period, and the project resources can be adjusted accordingly to speed up the third unstarted subproject in the critical path within the third project time period.

[0093] For example, when the third alternative subproject within the third project time period is advanced to the second project time period, the project resources corresponding to the third alternative subproject can be allocated to the second project time period, and the third alternative subproject can be started within the second project time period through the project resources corresponding to the third alternative subproject.

[0094] The beneficial effect brought about by the above-mentioned implementation method is that when the second alternative sub-project may be delayed, the third alternative sub-project within the third project time period can be started within the second project time period, and the third unstarted sub-project in the critical path within the third project time period can be accelerated by adjusting the project resources to ensure the progress of the unstarted sub-projects in the entire critical path, so as to ensure the completion progress of the entire project.

[0095] The beneficial effect brought about by the above implementation method is that, since the third alternative sub-project within the third project time period has been started in advance, sufficient space for project resource allocation has been reserved within the third project time period, which can ensure the completion progress of the entire project.

[0096] Figure 5 The flowchart of the third enterprise project management optimization method based on AOE network provided in the embodiment of the present application is as follows: Figure 5 As shown, the above method further includes S310 to S320, and S310 to S320 are described in detail below.

[0097] S310: Obtain the progress status of the third candidate subproject within the second project time period, and determine a third delay probability value of the third candidate subproject based on the progress status of the third candidate subproject;

[0098] When the third candidate subproject is started within the second project time period, the progress of the third candidate subproject within the second project time period can be monitored, and whether it has an impact on the progress of the entire project can be determined based on the progress of the third candidate subproject within the second project time period.

[0099] During operation, the progress status of the third candidate subproject within the second project time period can be obtained, and the third delay probability value of the third candidate subproject can be determined based on the progress status of the third candidate subproject to predict the delay possibility of the third candidate subproject.

[0100] S320: When the second delay probability value and the third delay probability value are both greater than the preset delay probability value, a prompt message is issued to increase project resources to speed up the third unstarted sub-project in the critical path within the third project time period.

[0101] When conducting project monitoring, when the second delay probability value is greater than the preset delay probability value and the third delay probability value is greater than the preset delay probability value, it indicates that at least two alternative sub-projects started in advance within the project time periods may be delayed, which may in turn cause delays in the unstarted sub-projects in the critical path. In order to ensure the progress of the unstarted sub-projects in the critical path, a prompt message may be issued to increase project resources to speed up the third unstarted sub-project in the critical path within the third project time period, so as to prompt the increase of project resources to improve the progress promotion effect of the unstarted sub-projects in the critical path.

[0102] For example, the preset delay probability value may be 50%, 60% or 70%.

[0103] The beneficial effect brought about by the above-mentioned implementation method is that when the alternative sub-projects started in advance within at least two project time periods may be delayed, it can be prompted to increase project resources to speed up the unstarted sub-projects in the critical path within the subsequent project time periods to ensure the progress of the unstarted sub-projects in the critical path of the entire construction project to ensure the progress of the entire critical path.
