Description

  The present invention relates to a work plan management apparatus, a work plan management method, and a work plan management program.

In recent years, CCPM (Critical Chain Project Management) has attracted attention as a project management method. This CCPM applies the basic principle of TOC (Theory of Constants) to a project management method, and aims at managing the deadline of the entire project or improving work efficiency in a project work with many uncertainties. In CCPM, work efficiency is improved by eliminating as many multi-tasks that the same worker has multiple tasks during the same period, and the number of days or time (buffer) in each process of the managed project is eliminated. Instead, a CCPM plan that is a project schedule that secures a buffer common to the entire project, called a project buffer, is generated. Then, the progress of the project is grasped and managed based on the consumption of the project buffer in the CCPM plan.
Patent Document 1 describes that work is allocated to a worker by matching a work deadline and a margin calculated from past results, work contents, and a worker's skill.

The input unit 11 is a device having a function for inputting information from a user, such as an input key, a mouse, and a touch panel. The input unit 11 receives input of resource information and project information from an administrator. The resource information is information regarding workers (resources) who perform work in a project to be managed (hereinafter also referred to as PJ). The resource information includes, for example, the worker's name and identification information.

The project information is a work plan generated based on the CCPM. FIG. 2 is a diagram illustrating a data example of project information. The project information includes a project name, task name, start date, end date, preceding task, resource name, priority, and the like. The priority is information indicating the degree to which the corresponding task is given priority over other tasks, and is indicated by a numerical value, for example. Here, the larger the priority value, the higher the priority, and the smaller the priority value, the lower the priority.
FIG. 2A is an example of first project information input to the input unit 11. This project is composed of a plurality of task groups in which work periods are connected. FIG. 2B is an example of second project information input to the input unit 11, and each project information is associated with a task ID as in FIG. This project includes one task, and this task is, for example, a task that is suddenly added. Such a project is hereinafter referred to as a maintenance project. Here, the maintenance project is, for example, inspection work, business trip, meeting, failure handling, etc. that occur suddenly. FIG. 2C is an example of third project information input to the input unit 11, and each project information is associated with a task ID as in FIG. This project is a maintenance project. FIG. 2D is an example of the fourth project information input to the input unit 11, and each project information is associated with the task ID as in FIG. This project is a maintenance project.

  The control unit 13 controls each unit included in the administrator terminal 1. For example, the control unit 13 causes the output unit 12 to display resource information and project information input from the input unit 11. Further, the control unit 13 transmits information to other computer devices connected via the network, and receives information from the other computer devices. In addition, the control unit 13 transmits the resource information and project information input to the input unit 11 to the work plan management apparatus 2.

The work plan management device 2 is a work plan management computer device that manages a project to be managed, and includes a resource information storage unit 21, a project information storage unit 22, a CCPM plan generation unit 23, and a CCPM plan update unit 24. CCPM plan storage unit 25.
The CCPM plan generator 23 outputs the CCPM plan a to the CCPM plan updater 24, and stores the updated CCPM plan b from the CCPM plan updater 24 to the CCPM plan storage unit 25.

The resource information storage unit 21 stores the resource information transmitted from the administrator terminal 1. The project information storage unit 22 stores project information transmitted from the administrator terminal 1.
The CCPM plan generation unit 23 generates a CCPM plan by adding a CC attribute or a non-CC attribute, setting a project buffer, and setting a merge buffer based on the project information stored in the project information storage unit 22. Here, the CC attribute is information indicating whether or not the task is a critical chain in the project. For example, if the task is a critical chain, “○” is associated and stored. Is not remembered. The non-CC attribute is information indicating whether or not the task is not a critical chain in the project. For example, if it is not a critical chain, “○” is associated and stored, and if it is a critical chain, nothing is stored. . The CCPM plan is a project plan using CCPM. Further, although the project buffer is half the total number of days of each task of the CC attribute project (rounded up), it may be set in half-day units or in time units. The CCPM plan generation unit 23 outputs the generated CCPM plan to the CCPM plan update unit 24 and stores it in the CCPM plan storage unit 25.

FIG. 3 is a diagram illustrating a data example of a CCPM plan generated by the CCPM plan generating unit 23 based on the project information illustrated in FIG.
The CCPM plan is composed of task ID, project name, task name, work start date, work end date, predecessor task, resource name, CC attribute, non-CC attribute, project buffer consumption, merge buffer consumption, and priority. ing. The task ID is 1 to 7, and the project name is A-project and maintenance system. The task name consists of tasks A, B, C, D and tasks X, Y, Z. As the start date and the end date of each task, each task is executed on September 1 and 2011, one or two days from September 7, 2011. In the case of a task having a preceding task, the task starts after the preceding task ends. In this embodiment, the maintenance project having a high priority is given priority and the CC attribute task is executed thereafter. However, the CC attribute work may be executed ahead of the maintenance project.

  In FIG. 3, the CC attribute and the non-CC attribute are set, and the project buffer and the merge buffer are set. There are task A, task B, and task C having a CC attribute based on the CCPM plan, and task D having a non-CC attribute based on the CCPM plan. The project buffer consumption and the merge buffer consumption are 0, that is, the project buffer and the merge buffer are not consumed, but the tasks performed by the same resource on the same work day are duplicated.

  The CCPM plan update unit 24 performs an update process based on the CCPM plan read from the CCPM plan storage unit 25. Here, the update process refers to a process in which the CCPM plan update unit 24 determines whether each of the plurality of tasks is a CC and a work buffer of a task that has been determined to be a CC. This is a process for calculating the project buffer consumption. Specifically, it is a process of determining whether there is a duplicate task in each resource and allocating resources so that a task with a high priority is preferentially executed, and details will be described later. The CCPM plan update unit 24 stores the updated CCPM plan in the CCPM plan storage unit 25. The CCPM plan updating unit 24 overlaps the work period of the task with the higher project buffer consumption with the work period of the work with the lower project buffer consumption among the plurality of tasks for which the project buffer consumption is compared. The work periods not to be associated are stored in the CCPM plan storage unit 25 in association with each other. The CCPM plan update unit 24 reads the updated CCPM plan from the CCPM plan storage unit 25. The CCPM plan update unit 24 determines whether the CCPM plan is progressing as planned based on the updated CCPM plan read from the CCPM plan storage unit 25 and the work progress information input from the worker terminal 3. Then, the CCPM plan is updated based on the determination result.

FIG. 4 is a diagram illustrating a data example of a CCPM plan updated by the CCPM plan update unit 24 based on the project information illustrated in FIG.
The CCPM plan is updated to the data example of the CCPM plan generated by the CCPM plan generation unit 23 shown in FIG. 3, so that the project buffer consumption becomes 2/3 (about 67%), and the project buffer is consumed. Yes. However, the tasks that are handled by the same resource on the same work day do not overlap and are one task.
In the present embodiment, a positive real number is used for the priority, but a ratio, a decimal number, a rank, or the like may be used, or a flag indicating the priority may be used.
The CCPM plan storage unit 25 stores the CCPM plan generated by the CCPM plan generation unit 23 and the CCPM plan updated by the CCOM plan update unit 24.

The worker terminal 3 is a computer terminal of a worker who manages a project to be managed, and includes an input unit 31, an output unit 32, and a control unit 33.
The input unit 31 accepts input of work progress information for each resource that is working based on the updated CCPM plan, for example, on a daily basis, and manages work progress information for each task of each input resource. The data is transmitted to the device 2 and stored in the CCPM plan storage unit 25. Here, the work progress information is, for example, information indicating whether a scheduled task is delayed, for example, the number of remaining days for each task.
The output unit 32 outputs work progress information of each task of each resource received by the input unit 31.

  The control unit 33 controls each unit included in the worker terminal 3. For example, the control unit 33 causes the output unit 32 to display work progress information input from the input unit 31. Further, the control unit 33 transmits information to other computer devices connected via the network, and receives information from the other computer devices. In addition, the control unit 33 transmits work progress information input to the input unit 31 to the work plan management apparatus 2.

FIG. 5 is a schematic block diagram illustrating an example of the configuration of the CCPM plan update unit 24 according to the present embodiment.
The CCPM plan update unit 24 includes a task duplication determination unit 241, a CC attribute duplication determination unit 242, a project buffer consumption detection unit 243, a work plan change unit 244, a buffer processing unit 245, a project buffer comparison unit 246, and a merge buffer comparison unit 247. , A priority comparison unit 248, and a CC attribute change determination unit 249.

  Based on the CCPM plan a input from the CCPM plan generation unit 23, the task duplication determination unit 241 determines whether or not a plurality of tasks are assigned to the same resource in the same period in the order of close schedule. Judge task duplication. When it is determined that there is a duplicate task, the task duplication determination unit 241 outputs a determination result to the CC attribute duplication determination unit 242. On the other hand, when it is determined that a plurality of tasks are not assigned to the same resource in the same period, the task duplication determination unit 241 stores the updated CCPM plan b in the CCPM plan storage unit 25.

  The CC attribute duplication determination unit 242 determines how many CC attribute tasks exist for each resource and each task. When it is determined that each task of each resource has two or more CC attribute tasks, the CC attribute duplication determination unit 242 outputs the project information of each CC attribute to the project buffer consumption detection unit 243. On the other hand, when it is determined that the number of CC attribute tasks is less than two, that is, when the number of CC attribute tasks is one, the CC attribute duplication determination unit 242 generates a CCPM plan that prioritizes the CC attribute tasks. The result is output to the comparison unit 248. When there is no CC attribute task, that is, a non-CC attribute task, the CC attribute duplication determination unit 242 outputs non-CC attribute project information to the merge buffer comparison unit 247.

  When there are two or more CC attribute tasks input from the CC attribute duplication determination unit 242, the project buffer consumption amount detection unit 243 compares each project buffer consumption amount with the number of remaining days in each CC attribute task, Determine whether the project buffer consumption is the same. When the project buffer consumption amount detection unit 243 determines that the project buffer consumption amounts are the same, the project buffer consumption amount detection unit 243 outputs the project information to the priority comparison unit 248. On the other hand, when each project buffer consumption is not the same, each project buffer consumption and project information are output to the project buffer comparison unit 246. In this embodiment, the remaining days are used in the comparison of the project buffer consumption. However, a percentage or a ratio may be used, or the consumption may be compared in units of time.

The project buffer comparison unit 246 compares the project buffer consumption based on the project buffer consumption and the project information input from the project buffer consumption detection unit 243, and ranks the task of the CC attribute based on the project buffer consumption. To do. The project buffer comparison unit 246 outputs the project buffer consumption amount and the project information to the work plan change unit 244.
The work plan changing unit 244 is changed in the task work plan ranked in the project buffer comparison unit 246, the task work plan ranked in the priority order by the priority comparison unit 248, and the CC attribute change determination unit 249. The update process is performed on the CCPM plan based on the CC attribute.

  The buffer processing unit 245 performs consumption processing of each of the merge buffer and the project buffer based on the updated CCPM plan input from the work plan change unit 244. The buffer processing unit 245 consumes the buffer, and stores the updated CCPM plan b in the CCPM plan storage unit 25. The buffer processing unit 245 outputs the CCPM plan subjected to buffer consumption processing to the CC attribute change determination unit 249.

  Based on the non-CC attribute project information input from the CC attribute duplication determination unit 242, the merge buffer comparison unit 247 determines whether or not the remaining number of days of consumption of the merge buffer for each task is the same amount. When the merging buffer consumption amount of each task is the same amount, the merging buffer comparison unit 247 outputs the CCPM plan to the CC attribute change determination unit 249. On the other hand, when the consumption amount of the merging buffer of each task is not the same amount, the merging buffer comparison unit 247 outputs the project buffer consumption amount of each task and the merging buffer consumption amount of each task to the priority comparison unit 248. In the present embodiment, the remaining number of days is used in the comparison of the merging buffer consumption, but a percentage or a ratio may be used, or the consumption may be compared in time units.

  The priority comparison unit 248 includes the project information input from the CC attribute duplication determination unit 242, the project buffer consumption input from the project buffer consumption detection unit 243, and the merge buffer consumption input from the merge buffer comparison unit 247. Based on the above, the priority is determined, and each task is ranked. The priority comparison unit 248 outputs the CCPM plans ranked based on the priorities to the work plan change unit 244.

The CC attribute change determination unit 249 determines whether or not to change the CC attribute based on the CCPM plan input from the merge buffer comparison unit 247, the project buffer consumption of each project, and the merge buffer consumption of each task. . As a result of consumption of the merge buffer, when the period becomes longer than the work period of the CC attribute task, that is, when it is determined to change the CC attribute, the CC attribute change determination unit 249 changes the CC attribute and adds Consume the project buffer for tasks. The CC attribute change determination unit 249 deletes the CC attribute for the conventional CC attribute task, and changes the non-CC attribute. The CC attribute change determination unit 249 stores the CCPM plan b based on the changed CC attribute in the CCPM plan storage unit 25 via the work plan change unit 244 and the buffer processing unit 245.
On the other hand, if the result of consumption of the merging buffer is not a period longer than the work period of the CC attribute task, that is, if it is determined not to change the CC attribute, the CC attribute change determination unit 249 performs the updated CCPM plan b Is stored in the CCPM plan storage unit 25.

FIG. 6 is an example of a flowchart showing the resource allocation logic according to the present embodiment.
The task duplication determination unit 241 reads the CCPM plan stored in the CCPM plan storage unit 25 (S1). The task duplication determination unit 241 checks task duplication for each resource based on step S1 (S2). When the work for each resource is not duplicated (S2-No), the CCPM plan is stored in the CCPM plan storage unit 25. When the work for each resource is duplicated (S2-Yes), it is output to the CC attribute duplication determination unit 242.

  The CC attribute duplication determination unit 242 determines whether there are two or more CC attribute operations based on Step S2-Yes (S3). When there are two or more CC attribute works (S3-Yes), the CC attribute duplication determination unit 242 outputs the CC buffer to the project buffer consumption amount detection unit 243. When the number of CC attribute operations is less than two (S3-No), the CC attribute duplication determination unit 242 determines the CC attribute again.

  Based on step S3-Yes, the project buffer consumption detector 243 detects the project buffer consumption of each work of each resource, and determines whether or not each project buffer consumption is the same amount (S4). Based on step S3-No, the CC attribute duplication determination unit 242 determines whether there is no CC attribute work (S9). When each project buffer consumption is the same amount (S4-Yes), the project buffer consumption detection unit 243 outputs the priority to the priority comparison unit 248. If the project buffer consumption amounts are not the same (S4-No), the project buffer consumption amount detection unit 243 outputs the project buffer consumption amount to the project buffer comparison unit 246.

  Based on step S4-No, the project buffer comparison unit 246 compares the project buffer consumption, and generates a plan to be implemented from a project with a small project buffer consumption (S5). Based on step S4-Yes, the priority comparison unit 248 compares the priorities of the tasks and generates a CCPM plan to be implemented from the high priority tasks (S6). Based on step S5 and step S6, the work plan change unit 244 determines whether or not the project buffer is consumed (S7). When the project buffer is consumed (S7-Yes), the project buffer is consumed (S8), and the work plan change unit 244 stores it in the CCPM plan storage unit 25. When the project buffer is not consumed (S7-No), the work plan change unit 244 stores it in the CCPM plan storage unit 25.

  When there is no CC attribute task (S9-Yes), the merging buffer comparison unit 247 detects each merging buffer amount and determines whether or not each merging buffer consumption amount is the same (S10). When there is one CC attribute task (S9-No), the CC attribute and the priority are confirmed (S15), a high priority task, or a CCPM plan that implements the CC attribute task with priority is generated, and the CCPM It memorize | stores in the plan memory | storage part 25. FIG.

If the merging buffer consumption amounts are the same (S10-Yes), the task priorities are compared, and a CCPM plan that prioritizes and executes the high priority tasks is generated (S11). If the merging buffer consumption amounts are not the same amount (S10-No), a CCPM plan that preferentially implements the task with the smaller merging buffer consumption amount is generated (S12).
Based on step S11 and step S12, it is determined whether the additional task has a longer work period than the CC attribute task (S13). When the additional task has a longer work period than the CC attribute task (S13-Yes), the attribute of the task having the CC attribute newly and the task having the new CC attribute is changed (S14). Further, the project buffer is consumed and stored in the CCPM plan storage unit 25. When the additional task has a shorter work period than the CC attribute task (S13-No), the work plan is stored in the CCPM plan storage unit 25.

  FIG. 7 is a schematic Gantt chart showing an example of a CCPM plan optimized based on the maintenance project according to the present embodiment. As shown in FIG. 5, the work period is a work plan scheduled to start on September 1, 2011 and end on September 9, 2011, for example.

  The CCPM plan is a CC attribute project by resource 1 (R1), and is composed of tasks A, B, and C that are sequentially operated, and task D that is a non-CC attribute project that is operated by resource 2 (R2). Is done. The CCPM plan also includes a merge buffer provided at the task merge point of R1 and R2, and a project buffer provided after the final task of the CC attribute project.

The maintenance project is composed of a task X and a task Y that are worked by R1, and a task Z that is worked by R2.
The priority of the maintenance project is input as the maximum value (100), and is the highest priority operation.

  In the present embodiment, the work process is divided in units of one day, but may be managed in units of time or may be managed in units of half a day. In this embodiment, the CCPM plan and the maintenance project are used. However, a plurality of CCPM plans may be used, or a plurality of CCPM plans and a maintenance project may be used. In addition, the resource is implemented by two people, but it may be one person or a plurality of others.

  In FIG. 7, R1 is scheduled to perform task A as a project in the CC attribute plan of CC attribute on September 1, but task X is generated as a maintenance project on the same day. That is, R1 performs a plurality of tasks on the same day. Similarly, R2 is scheduled to perform task D as a project in the CCPM plan, but on the same day, task Z occurs as a maintenance project. That is, R2 performs a plurality of tasks on the same day. R1 is scheduled to perform task C as a project in the CC attribute based on the CCPM plan on September 4, but task Y is generated as a maintenance project on the same day.

FIG. 8 is a Gantt chart showing an example of task work period reallocation in each task of the first resource, which accompanies the CCPM plan update processing step according to the present embodiment.
In FIG. 8, the task of R1 is changed to a plan for executing task X, which is a maintenance project having a high priority, on September 1. The task A, task B, and task C that are CCPM plan tasks are changed to CCPM plans that are sequentially operated after the task X that is a maintenance project ends. It can be seen that the project buffer is consumed for one day as the work process is changed.
However, on September 4, R1 has a duplicate task and needs to perform the update process again.

FIG. 9 is a Gantt chart showing an example of a change in work period accompanying the work resource reallocation of the first resource and each task in the CCPM plan update process according to the present embodiment.
In FIG. 9, the task of R1 is changed to a plan for executing task Y, which is a maintenance project with a high priority, on September 4. As a result, the task B and task C that are CCPM plan tasks are changed to CCPM plans that are sequentially operated after the task Y that is a maintenance project ends. It can be seen that the project buffer is consumed for one more day due to the change of the work process, and is consumed for a total of two days.
However, there are no duplicate tasks and each task can be executed smoothly.

FIG. 10 is a Gantt chart showing an example of the work period reallocation of each task in each task of the second resource, accompanying the CCPM plan update processing step according to the present embodiment.
In FIG. 10, the task of R2 is changed to a plan for executing task Z, which is a maintenance project having a high priority, on September 1st. The task D that is a CCPM plan task is changed to a CCPM plan that is sequentially operated after the task Z that is a maintenance project ends. The project buffer is not consumed because the R2 task has a non-CC attribute.

  By performing the update process in FIG. 7, R1 is changed to a plan to execute the highest priority task X as a maintenance project on September 1st. Similarly, R1 has been changed to schedule the highest priority task Y as a maintenance project on September 4. Task A, task B, and task C are executed after the work of the highest priority task Y is completed by the update process. That is, the CCPM plan has no duplicate tasks due to the change of the start date on the 1st or 2nd. As a result, the project buffer is consumed for the number of days of the maintenance-type project of R1, but the project can be smoothly performed because there are no duplicate tasks. Similarly, R2 also performs update processing, so that R2 eliminates duplicate tasks and can smoothly perform a project.

As described above, according to the present embodiment, the work included in the project to be managed, the worker performing the work, the work period indicated by the start time and the end time of performing the work, and the work are compared with other work. A work plan storage unit (CCPM plan storage unit) that stores a plurality of work plans in which a priority indicating a priority level and a project buffer indicating a margin period set in advance for the project are associated with each other. 25) and a plurality of work plans stored in the work plan storage unit (CCPM plan storage unit 25), and whether or not there are a plurality of operations in which the worker and the work period overlap in the plurality of read work plans. The duplication judgment unit (task duplication judgment unit 241) and the duplication judgment unit (task duplication judgment unit 241) determine whether the worker and the work period overlap. When it is determined that there are a plurality of tasks, the priority comparison unit 248 that compares the priorities associated with the plurality of tasks and the duplication determination unit (task duplication determination unit 241) overlap the worker and the work period. When it is determined that there are a plurality of operations to be performed, the project buffer comparison unit 246 that compares the project buffer consumption amounts of the plurality of operations and the project buffer comparison unit 246 determine that the project buffer consumption amounts are the same. In the case where the priority is compared, the work period of the work with the lower priority among the plurality of works whose priorities are compared by the priority comparison unit 248 is associated with the work period that does not overlap with the work period of the higher priority work. Work plan update unit (CCPM meter) for performing work plan update processing to be stored in the work plan storage unit (CCPM plan storage unit 25) Further comprising an updating unit 24), and characterized. Thereby, the work plan which eliminated the worker's multitasking can be generated.
