Description

  The present invention relates to a project planning method, a project planning program, and a project planning system.

  The work breakdown structure is obtained by expanding a workflow, which is an entire business, into a work, which is an individual business unit, in order to support a project such as an engineering business. Standard work time (ST: Standard Time) that can complete a work unit in standard time is set individually, and resources such as people and equipment that are necessary and can be assigned to each work unit are assigned. Decide the unit man-hours and make a schedule for them.

Japanese Patent Application Laid-Open No. 2004-151867 has a proposal characterized in that a factor of interest having a correlation with man-hours is extracted based on work completion data indicating the component installation position and size, and man-hours are calculated using a prediction approximation formula. Patent Document 2 has a proposal characterized by evaluating a project risk based on qualitative ability information about the project. Patent Document 3 has a proposal characterized in that the number of man-hours is estimated based on the qualitative personnel ability and the use case difficulty of software development.

  None of the conventional techniques described above estimate man-hours without using the standard work time, and thus the estimation accuracy cannot be sufficiently increased. On the other hand, if the standard work time is used as the estimated work time as it is, the work-specific factors such as the difficulty level of the work to be worked on and the ability of resources such as workers to perform the work are not reflected in the estimate. There were variations in the accuracy of estimates.

  Therefore, the main object of the present invention is to estimate the working time of each work in the workflow with high accuracy when solving the above-described problem and planning a project for executing the workflow.

  In order to solve the above problems, the present invention calculates the estimated work time of each resource based on the work difficulty level of the work constituting the workflow executed in the project and the skill level of the resource that executes the work, A project planning method for creating a project plan by allocating the calculated estimated work time to each work, and the computer shows work correspondence information indicating correspondence between each work and the necessary skills for executing the work. And storing skill correspondence information indicating correspondence between each resource and the skill possessed by the resource in a storage device, inputting the workflow, numerical input of a work difficulty determination attribute for calculating the work difficulty, And a numerical input of a skill level determination attribute for calculating the skill level For each work of the workflow that is received and input through the above, the required skill of the work correspondence information and the skill of the resource of the skill correspondence information are collated to correspond to the resource for executing the work In addition, for the associated work, the work difficulty level is calculated by substituting the input numerical value of the work difficulty level determination attribute into a predetermined work difficulty level determination function, and the calculated work difficulty level and The work difficulty level correction value is calculated by comparing with a plurality of threshold values, and the input value of the skill level determination attribute is substituted for a predetermined skill level determination function for the skill of the associated resource. The skill level is calculated, and the skill level correction value is calculated by comparing the calculated skill level with a plurality of threshold values. The estimated work time obtained by correcting the standard work time is calculated by using the calculated work difficulty level correction value and the skill level correction value for the standard work time assigned to the work. It is characterized by that. Other means will be described later.

  According to the present invention, when planning a project for executing a workflow, it is possible to estimate the work time of each work in the workflow with high accuracy.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an explanatory diagram showing a workflow in a project. The work breakdown structure hierarchically defines the business (work) structure so that it flows from upstream to downstream. In FIG. 1, an upstream-downstream relationship is expressed by showing an arrow from the upstream workpiece to the downstream workpiece. Each work constituting the workflow is classified into basic design or detailed design. For example, the basic design is a system design, an electrical instrumentation control plan, a layout design, and a shielding design. In addition, a work ID for specifying the work is indicated in parentheses before the name of each work. For example, the system design work ID is “W1”.

  FIG. 2 is a Gantt chart showing a plan table in the project. The vertical axis of the Gantt chart is each work specified by the work ID, and the time axis on which the time elapses as the horizontal axis goes to the right. FIG. 2 (a) shows an appropriate project plan in which no contention occurs in resources for performing work. The resource here is a worker (human resource).

  For example, the resource “Reiko Niwa (R1)” performs the work with the work ID “W1” from the beginning of January to the middle of March 2007. Note that the resource ID for identifying the resource is shown in parentheses after the name of each resource. For example, the resource ID of Reiko Niwa is “R1”. The horizontal length of the rectangle indicating each resource in this Gantt chart is the estimated work time period for that resource. That is, the estimated period for implementing the work with the work ID “W1” by the resource “Reiko Niwa (R1)” is two and a half months.

  On the other hand, FIG. 2B shows an inappropriate project plan due to resource conflicts. The accuracy of the estimation period for the resource “Reiko Niwa (R1)” was poor, and it was estimated to be two and a half months. On the other hand, the resource “Reiko Niwa (R1)” was planned to implement another “W2” work from the beginning of April 2007 after implementing the “W1” work. Therefore, in April 2007, the resource “Reiko Niwa (R1)” is allocated to two works “W1” and “W2” redundantly. In this way, the same resource is assigned to a plurality of works is called resource contention.

  Thus, an inappropriate project plan is caused by resource contention, and resource contention is caused by poor accuracy of the estimated work time period. Therefore, in order to create an appropriate project plan in which resource competition does not occur and each resource is efficiently allocated to each work, it is important to realize highly accurate estimation processing. In this embodiment shown below, the standard work time for performing a predetermined work is not used as it is, but the standard work time is corrected based on the detailed information of the work and the detailed information of the resource. As a result, highly accurate estimation processing is realized.

  FIG. 3 is a configuration diagram of the project planning system 9 (computer). The project planning system 9 includes an input device 1 including a keyboard and a mouse for allowing a user to input input information, a display device 2 including a display for displaying and notifying various information to the user, and a project. It is configured as a computer including at least a storage device 3 for storing data, a memory as storage means used when performing arithmetic processing, and an arithmetic processing device for performing the arithmetic processing. The memory is constituted by a RAM (Random Access Memory) or the like. Arithmetic processing is realized by an arithmetic processing unit configured by a CPU (Central Processing Unit) executing a program on a memory.

  The project planning system 9 stores work difficulty level information 12, work difficulty level determination information 13, work reference information 15, and work difficulty level reference information 16 as information about the workflow 11 in the storage device 3. The workflow 11, the work reference information 15, and the work difficulty level determination information 13 are setting information input in advance via the input device 1.

  The project planning system 9 includes a work difficulty level reference information input unit 17 and a work difficulty level determination unit 14. First, when the input of the work difficulty reference information 16 is received via the work difficulty reference information input unit 17, a work difficulty determination attribute is obtained based on the work reference information 15. Next, the workpiece difficulty level determination unit 14 assigns the workpiece difficulty level determination attribute to the workpiece difficulty level determination function of the workpiece difficulty level determination information 13, thereby determining the workpiece difficulty level of the workpiece difficulty level information 12 for each workpiece. Ask.

  The project planning system 9 stores a resource list 21, skill level information 22, skill level determination information 23, skill reference information 25, and skill level reference information 26 in the storage device 3 as information about resources. The resource list 21, skill reference information 25, and skill level determination information 23 are setting information input in advance via the input device 1.

  The project planning system 9 includes a skill level reference information input unit 27 and a skill level determination unit 24. First, when input of the skill level reference information 26 is received via the skill level reference information input unit 27, a skill level determination attribute is obtained based on the skill reference information 25. Next, the skill level determination unit 24 obtains the skill level of the skill level information 22 for each skill of the resource by substituting the skill level determination attribute into the skill level determination function of the skill level determination information 23.

  The project planning system 9 corrects the standard work time based on the work difficulty obtained by the work difficulty determination unit 14 and the correction values corresponding to the skill levels obtained by the skill level determination unit 24. The ST information 31 is stored in the storage device 3. The project planning system 9 includes an ST correction unit 32 and a project planning unit 35. The ST correction unit 32 corrects the standard work time based on the ST information 31, thereby estimating the work time for each combination of the work and the resource in charge of the work. The project planning unit 35 creates a project plan shown in FIG. 2A and the like based on the work time estimated by the ST correction unit 32.

  Here, after the created project plan is executed, the estimated work time can be compared with the work time actually worked on by the resource. Therefore, the project planning system 9 receives from the input device 1 performance information 33 indicating the actual working time of the resource and stores it in the storage device 3. Further, the project planning system 9 provides the display device 2 with a comparison so that the performance information 33 can be compared with various information stored in the storage device 3 (mainly, the work difficulty level determination information 13 and the skill level determination information 23). An adjustment display unit 34 is provided for displaying the information, causing the user to edit the displayed various information, and updating the editing result in the storage device 3. The edit screen of the adjustment display unit 34 will be described later.

表１に示すワーク難易度情報１２は、ワークＩＤ、ワーク名称、ワーク難易度、および、ワーク難易度決定属性を対応づけて構成される。ワークＩＤは、ワークフロー１１のワーク単位のＩＤである。ワーク名称は、ワークＩＤで特定されるワークの名称である。ワークＩＤで特定されるワークのワーク難易度である。ワーク難易度決定属性は、ワーク難易度を決定するための属性である（詳細は後記）。例えば、ワークＩＤ「Ｗ１」のワーク名称「システム設計」は、ワーク難易度が「３」であるので、ワーク難易度が「１」であるワークＩＤ「Ｗ５」のワーク名称「機械設計」よりも難易度の高い（換言すると、作業時間が長くかかる）ワークである。

The work difficulty level information 12 shown in Table 1 is configured by associating a work ID, a work name, a work difficulty level, and a work difficulty level determination attribute. The work ID is a work unit ID of the workflow 11. The work name is the name of the work specified by the work ID. The work difficulty level of the work specified by the work ID. The work difficulty level determination attribute is an attribute for determining the work difficulty level (details will be described later). For example, since the work name “system design” of the work ID “W1” has a work difficulty level “3”, the work name “machine design” of the work ID “W5” whose work difficulty level is “1”. It is a work with a high degree of difficulty (in other words, a long work time).

表２に示すワーク参考情報１５は、ワーク難易度決定属性、および、ワーク難易度参考情報１６を対応づけて構成される。ワーク難易度参考情報１６は、例えば、プロジェクトのワーク単位で対象となる成果物に関連する（関連するとは、例えば、作業対象物カテゴリが互いに同じである）他の製品あるいは部品の数を示す「関連部品数」、成果物のスペックの数を示す「スペック数」、ワークをさらに詳細に手順化した際の手順の数を示す「詳細手順数」、繰り返し開発を行う回数である「リピート開発回数」、および、ワーク単位で対象となる成果物である製品を審査するときの「製品審査レベル」である。

The work reference information 15 shown in Table 2 is configured by associating the work difficulty determination attribute and the work difficulty reference information 16 with each other. The work difficulty level reference information 16 indicates, for example, the number of other products or parts related to the target product in the work unit of the project (related to, for example, the work object category is the same as each other). “Number of related parts”, “Number of specifications” indicating the number of specifications of deliverables, “Number of detailed procedures” indicating the number of procedures when the work is further procedurally, “Number of repeat developments”, which is the number of times of repeated development ”And“ Product screening level ”when a product, which is a target product, is screened for each work.

  Each work difficulty level determination attribute is quantified based on the corresponding work difficulty level reference information 16. For example, the attribute “wa1” has the same value as the number of related parts. The other work difficulty level reference information 16 includes, for example, the number of related deliverables when paying attention to the deliverable that is the target of the work, and the number of related works when paying attention to the work.

表３に示すワーク難易度決定情報１３は、作業対象物カテゴリ、ワーク難易度決定関数、および、１つ以上のワーク難易度決定属性を対応づけて構成される。作業対象物カテゴリ別に決定されるワーク難易度は、表で「○」が示されているワーク難易度決定属性の値を、ワーク難易度決定関数に代入することで、計算される。

The work difficulty level determination information 13 shown in Table 3 is configured by associating a work object category, a work difficulty level determination function, and one or more work difficulty level determination attributes. The work difficulty level determined for each work object category is calculated by substituting the value of the work difficulty level determination attribute indicated by “◯” in the table into the work difficulty level determination function.

For example, it is assumed that a work difficulty level determination function “WF1” having three levels of difficulty for the work object category “C1” is defined as follows. “200” and “1000” are examples of threshold values for classifying the calculation result of the work difficulty determination function into three stages.
WF1 (attribute wa1, attribute wa3, attribute wa4, attribute wa5) = attribute wa1 x coefficient "1" + attribute wa3 x coefficient "100" + attribute wa4 x coefficient "10" + attribute wa5 x coefficient "1"
・ Work difficulty = 1 (if WF1 <200)
・ Work difficulty = 2 (if 200 ≦ WF1 ≦ 1000)
・ Work difficulty = 3 (if WF1> 1000)
For example, the work name “system design” (see Table 1) of the work ID “W1” for the work object category “C1” has a work difficulty level determination function “WF1” of 100 × 1 + 3 × 100 + 1.5 × 10. Since + 987 × 1 = 1402 and 1402> 1000, the work difficulty level = 3.

表４に示すリソースリスト２１は、リソースＩＤ、部署ＩＤ、および、氏名を対応づけて構成される。例えば、氏名「丹羽礼子」は、「設計１課」に所属し、「Ｒ１」というリソースＩＤが割り当てられている。なお、リソースは、設計者などの人的リソースだけでなく、設備などの物的リソースを定義してもよい。

The resource list 21 shown in Table 4 is configured by associating resource IDs, department IDs, and names. For example, the name “Reiko Niwa” belongs to “Design 1 Section” and is assigned a resource ID “R1”. The resource may define not only a human resource such as a designer but also a physical resource such as equipment.

表５に示すスキルレベル情報２２は、リソースＩＤ、スキル、スキルレベル、および、スキルレベル決定属性を対応づけて構成される。リソースＩＤで特定されるリソースは、スキルレベルに応じたスキルを有しており、そのスキルレベルは、スキルレベル決定属性より計算されたものである。スキルは、リソースがワークを実施するための能力であり、同じスキルを有していてもスキルレベルが高いほど、リソースがワークをより効率的に実施する。例えば、リソースが設備の場合、スキルは設備の機能（スペックの種類）を示し、スキルレベルはその機能のスペック値を示す。

Skill level information 22 shown in Table 5 is configured by associating resource IDs, skills, skill levels, and skill level determination attributes. The resource specified by the resource ID has a skill corresponding to the skill level, and the skill level is calculated from the skill level determination attribute. A skill is an ability for a resource to perform a work, and even if the resource has the same skill, the higher the skill level, the more efficiently the resource performs the work. For example, when the resource is equipment, the skill indicates the function of the equipment (spec type), and the skill level indicates the spec value of the function.

  For example, Reiko Niwa with resource ID “R1” has three skills: “device design” with skill level 3, “modeling” with skill level 1, and “assembly design” with skill level 2. Since the skill “equipment design” has a higher skill level than the skill “assembly design”, it is understood that the skill “equipment design” is proficient (in other words, good). On the other hand, Haruki Ishuin with resource ID “R3” has “modeling” at skill level 3, so when assigning the same “modeling” job, the work time is shorter than Reiko Niwa at skill level 1. .

表６に示すスキル参考情報２５は、スキルレベル決定属性、および、スキルレベル参考情報２６を対応づけて構成される。スキルレベル参考情報２６は、例えば、プロジェクトに関わる人的リソースにおいて、スキルに関連する資格の数を示す「関連資格数」、スキルに関連する資格の種類から特定される「資格レベル」、スキルを使ってワークに携わった「経験年数」、スキルを使って担当した「担当プロジェクト数」、およびスキルを使って経験した「関連業務経験数」である。一方、スキルレベル参考情報２６は、プロジェクトに関わる物的リソースにおいて、例えば、プロジェクトに関わる設備リソースのワーク実施に関連するスペックの種類およびその定量値である。

Skill reference information 25 shown in Table 6 is configured by associating skill level determination attributes and skill level reference information 26. The skill level reference information 26 includes, for example, “related qualification number” indicating the number of qualifications related to the skill, “qualification level” specified from the type of qualification related to the skill, and the skill in the human resource related to the project. The number of years of experience involved in the work, the number of projects in charge using skills, and the number of related work experiences experienced using skills. On the other hand, the skill level reference information 26 is, for example, a specification type and a quantitative value related to work execution of equipment resources related to the project in the physical resources related to the project.

表７に示すスキルレベル決定情報２３は、スキル、スキルレベル決定関数、および、スキルレベル決定属性を対応づけて構成される。スキルのスキルレベルは、表中「○」が付いているスキルレベル決定属性を引数とするスキルレベル決定関数により計算される。

Skill level determination information 23 shown in Table 7 is configured by associating skills, skill level determination functions, and skill level determination attributes. The skill level of the skill is calculated by a skill level determination function having a skill level determination attribute with “O” in the table as an argument.

For example, it is assumed that a skill level determination function “SF17” having three levels of difficulty is defined as follows. “60” and “80” are examples of threshold values for classifying the calculation result of the skill level determination function into three levels.
SF17 (attribute sa1) = attribute sa1 x coefficient "100"
・ Skill level = 1 (if SF1 <60)
・ Skill level = 2 (if 60 ≦ SF1 ≦ 80)
・ Skill level = 3 (if SF1> 80)
For example, the skill “equipment design” (see Table 5) of the resource ID “R1” has the skill level determination function “SF17” of 15 × 100 = 150 and 150> 80, so the skill level = 3.

表８に示すＳＴ情報３１は、ワークＩＤ、必要スキル、標準作業時間（ＳＴ）、スキルレベル補正値、および、ワーク難易度補正値を対応づけて構成される。まず、ワークＩＤで特定されるワークを実施するためには、必要スキルで特定されるスキルを有しているリソースが必要となる。そのワークと必要スキルとの組み合わせでの補正前の標準作業時間が、対応づけられている。そして、この補正前の標準作業時間に対して、スキルレベル補正値を元にしたスキルレベル補正、および、ワーク難易度補正値を元にしたワーク難易度補正を行うことにより、高精度の作業時間を計算する。

The ST information 31 shown in Table 8 is configured by associating a work ID, a necessary skill, a standard work time (ST), a skill level correction value, and a work difficulty level correction value. First, in order to implement the work specified by the work ID, a resource having the skill specified by the necessary skill is required. The standard work time before correction for the combination of the work and the required skill is associated. Then, by performing skill level correction based on the skill level correction value and work difficulty level correction based on the work difficulty level correction value with respect to the standard work time before correction, a highly accurate work time Calculate

  In this way, the standard work time of a work in a project such as engineering work is not determined as a standard time, but is quantitatively corrected according to the difficulty level of the work and the skill level of the resource performing the work. can do.

  The skill level correction values are, for example, level 3, level 2, and level 1 in order from the highest level, and the intermediate level 2 is normalized as the standard correction value “1”. Then, the correction value of level 3 higher than level 2 is made smaller than 1, and the correction value of level 1 lower than level 2 is made larger than 1. This reflects a phenomenon in which the higher the skill level, that is, the more skilled the skill is, the shorter the work time (that is, the smaller the correction value).

  The difficulty level correction value is, for example, three levels of difficulty level 3, difficulty level 2, and difficulty level 1 in descending order of difficulty, and the intermediate difficulty level 2 is normalized as a standard correction value “1”. Then, the correction value of difficulty level 3 higher than difficulty level 2 is larger than 1, and the correction value of difficulty level 1 lower than difficulty level 2 is smaller than 1. This reflects the phenomenon that the work time becomes higher (that is, the correction value becomes larger) as the work has a higher difficulty level.

An example of the standard work time correction calculation performed by the ST correction unit 32 is given below. Consider a case where the “modeling” skill is exercised in order to realize the work with the work ID “W72”. It is assumed that the work difficulty level of the work ID “W72” is “3” and the skill level of “modeling” of the resource in charge of the work is “1”. This example reflects an event handled by an inexperienced person in charge of a difficult work. Then, the following calculation is performed for the standard work time “10” of “modeling” described in the ST information 31.
Work time after correction = 10 (standard work time) × 1.6 (skill level 1 skill level correction value) × 1.3 (work difficulty level 3 work difficulty level correction value) = 20.8

  As a result, the work time was corrected from 10 [days], which is the standard work time before correction, to 20.8 [days] after correction. This makes it possible to grasp a high-accuracy estimate that takes more than twice as much work time when an inexperienced person is in charge of difficult work at the planning stage before the actual work starts. . As a result, it is possible to support for taking appropriate measures such as changing the assignment to another person in charge with a high skill level or creating a project plan with a sufficient working time.

  FIG. 4 is a screen diagram showing an adjustment screen displayed by the adjustment display unit 34. The adjustment screen displays the decision function editing unit 101, the decision function display unit 102, and the reflection result display unit 103 on the same screen. The decision function editing unit 101 displays the work difficulty level adjustment 101b and the skill level adjustment 101c in association with each other with the work ID 101a.

  The work difficulty level adjustment 101 b is a work difficulty level determination attribute of the work difficulty level information 12 and its attribute value, a coefficient to the attribute constituting the work difficulty level determination function, its coefficient value, and the work difficulty level correction of the ST information 31. The value is displayed and numerical editing of each of these parameters is accepted.

  The skill level adjustment 101c displays the skill level determination attribute of the skill level information 22 and its attribute value, the coefficient to the attribute constituting the skill level determination function, its coefficient value, and the skill level correction value of the ST information 31. The numerical editing of each of these parameters is accepted.

  As a means for editing the numerical value, the adjustment display unit 34 may be input from a text box that can be input by clicking on the numerical value, or may be input by dragging a scroll bar 101d that moves up and down in conjunction with the numerical value. May be. When the adjustment display unit 34 detects an event indicating that the numerical value has been changed by editing, the adjustment display unit 34 performs control so as to recalculate the estimated work time based on the standard work time correction process based on the changed numerical value.

  The decision function display unit 102 displays a decision function (work difficulty level decision function and skill level decision function) to be edited by the decision function editing unit 101. The reflection result display unit 103 displays, for each work example, the estimated work time obtained by the standard work time correction process and the actual work time of the actual information 33 input separately in a bar chart. The smaller the difference between the two work times, the higher the accuracy of the estimation. When the estimated work time is recalculated under the control of the adjustment display unit 34, the result of the recalculation is reflected in the display content of the reflection result display unit 103.

  As described above, the user can immediately know the accuracy of the estimated work time on the graph by editing each parameter of the decision function editing unit 101. As a result, each parameter can be edited through trial and error, and a decision function that enables highly accurate estimation can be updated. The reflection result display unit 103 displays a plurality of work cases side by side. As a result, it is possible to suppress the input of a parameter that is overfitted only to a specific workpiece case.

  FIG. 5 is a flowchart showing the main process of the project plan.

  First, the input device 1 receives an input of the workflow 11 (S11). The control unit of the project planning system 9 executes a loop for sequentially selecting works of the input workflow 11 one by one (S12 to S17). The control unit of the project planning system 9 associates the selected work with a resource for executing the work (S13).

  And the workpiece difficulty level determination part 14 calculates the workpiece difficulty level of the matched workpiece | work, and acquires the workpiece difficulty level correction value from the ST information 31 (S14). The skill level determination unit 24 calculates the skill level of the associated resource, and acquires the skill level correction value from the ST information 31 (S15). The ST correction unit 32 corrects the standard work time of the associated work by using the work difficulty level correction value and the skill level correction value to obtain an estimated work time (S16).

  Further, based on the calculated estimated work time and resource constraints, the project planning unit 35 plans the work period of the resource for executing the work on the work of the workflow 11 (S21). The input device 1 accepts an input of the record information 33 that is a result of the work being performed (S22). The adjustment display unit 34 adjusts the parameter for calculating the estimated work time by comparing the estimated work time with the work time of the input result information 33 (S23). The adjusted parameter is used to calculate the estimated work time from the next time.

  FIG. 6 is a flowchart showing S13 (processing for associating a selected work with a resource for executing the work).

  First, for the selected work, necessary skills for executing the work are extracted from the ST information 31 (S101). Next, for the extracted necessary skill, a resource holding the skill is extracted from the skill level information 22 (S102). Then, it is determined whether or not the skill level of the extracted resource is appropriate (S103). The appropriate skill level indicates that the skill level of the resource is 2 or 3, for example, when the skill level of the necessary skill for performing the work is set to “2 or more”. If Yes in S103, the selected work is associated with the extracted resource (S104). If No in S103, the process returns to the main process without associating.

  FIG. 7A is a flowchart showing S14 (a process of calculating the work difficulty level of the associated work and obtaining the work difficulty level correction value from the ST information 31).

  The workpiece difficulty level reference information input unit 17 receives input of workpiece difficulty level reference information 16 related to the associated workpiece (S201). The workpiece difficulty level determination unit 14 obtains a workpiece difficulty level determination attribute based on the input workpiece difficulty level reference information 16 (S202). The work difficulty level determination unit 14 obtains the work difficulty level of the work difficulty level information 12 for each work by substituting the work difficulty level determination attribute into the work difficulty level determination function of the work difficulty level determination information 13 (S203). ). The workpiece difficulty level determination unit 14 acquires a workpiece difficulty level correction value corresponding to the calculated workpiece difficulty level from the ST information 31 (S204).

  FIG. 7B is a flowchart showing S15 (a process of calculating the skill level of the associated resource and acquiring the skill level correction value from the ST information 31).

  The skill level reference information input unit 27 receives the input of the skill level reference information 26 related to the associated resource (S211). The skill level determination unit 24 obtains a skill level determination attribute based on the input skill level reference information 26 (S212). The skill level determination unit 24 obtains the skill level of the skill level information 22 for each skill of the resource by substituting the skill level determination attribute into the skill level determination function of the skill level determination information 23 (S213). The skill level determination unit 24 acquires a skill level correction value corresponding to the obtained skill level from the ST information 31 (S214).

  FIG. 8 is a flowchart showing S21 (a process for planning the work period of the resource for executing the work on the work of the workflow 11 based on the calculated estimated work time and resource constraints).

  First, the input workflow 11 is acquired (S301). Next, a loop for selecting works in order according to the time order defined in the workflow 11 is executed (S302 to S307). And the resource which has the required skill matched with the selected workpiece | work is selected (S303). Further, the work time of the workpiece is determined for the selected resource (S304).

  Here, it is determined whether or not there is a resource conflict with another work for the selected resource (S305). As shown in FIG. 2B, the resource contention indicates that one resource is allocated to a plurality of works in duplicate at the same time. If Yes in S305, the work time of the selected workpiece is moved on the time axis so as to avoid resource contention (S306). If No in S305, the work time of the selected workpiece is confirmed.

  FIG. 9 is a flowchart showing S23 (processing for adjusting the parameter for calculating the estimated work time by comparing the estimated work time with the work time of the record information 33).

  First, a loop for sequentially selecting all works in the workflow 11 is executed (S401 to S409). The input of the record information 33 corresponding to the selected work is received (S402). The estimated work time estimated by the ST correction unit 32 is compared with the work time of the input record information 33 and displayed on the reflection result display unit of the adjustment screen (FIG. 4) (S403).

  Here, it is determined whether or not the difference time between the displayed work times is within an error range (S404). If Yes in S404, the calculation has already been completed with sufficient accuracy and there is no need to change the parameters, so the loop for the selected workpiece is terminated (S409). If No in S404, the user is inquired whether to adjust the decision function (S405). If No in S405, since it is determined that the user does not need to change the parameter, the loop for the selected workpiece is terminated (S409). If Yes in S405, the value of each parameter constituting the decision function is changed (S406). Then, it is determined whether or not the parameter value has been changed (S407). If Yes in S407, the estimated work time is recalculated based on the changed parameter value (S408).

  According to the present embodiment described above, the standard work time is corrected according to the work difficulty level and the skill level of the resource, and the work time is estimated, so that the estimated accuracy can be calculated with high accuracy and the accuracy varies. Can be suppressed. As a result, the project plan and the cost calculation for executing the plan can be performed with higher accuracy, which is effective for time and monetary adjustment with the customer who delivers the project deliverables. In other words, since it is possible to correct an error in project planning and estimation, it is possible to suppress the occurrence of enormous loss costs.
