- the movement time between work places is used as the first restriction condition, it is possible to make an allocation assuming that all the workers move by the same means of transportation (for example, walking).
- the travel time between work places depends on the distance between work places. Therefore, the distance between work places may be used instead of the travel time between work places.
- the allocation execution unit 105 allocates based on the linear programming problem using the time index f (x) as an objective function.

- the work places A to F are geographically separated.
- the task data includes travel time data indicating travel time between locations A and B, travel time between locations A and C, travel time between locations A and D, ..., Travel time between locations E and F, and Includes start time data indicating the start times of tasks A to F.
- the travel time exists for each of the 15 sections formed by any two of the locations A to F, but FIG. 3 shows only the travel time for the six sections.
- FIG. 3 shows only the travel time for the six sections.
- the travel time between locations A and B is 20 minutes
- the travel time between locations B and C is 10 minutes
- the travel time between locations C and A is 50 minutes
- the travel time between D and E is 30 minutes
- the travel time between locations E and F is 20 minutes
- the travel time between locations F and D is 50 minutes.
- the start time of task A is 10:00
- the start time of task B is 9:00
- the start time of task C is 9:00
- the start time of task D is 11:00
- the start time of task F is 10:00
- the start time of task F is 8:00.
- optimization is executed without considering the second limiting condition (for example, task start time).
- an allocation table may be obtained in which a plurality of tasks having the same start time are assigned to one worker.
- the worker A may be assigned tasks A, B, and C
- the worker B may be assigned tasks D, E, and F.
- the start times of tasks B and C are both 9:00, and the allocation table is not feasible. If the determination condition includes a condition that a task with the same start time is not assigned to one worker, this assignment table does not satisfy the determination condition.
- the correction unit 107 corrects the weights related to the task that causes the allocation table to not satisfy the determination condition among the weights included in the time index.
- the tasks that cause the allocation table not to satisfy the determination conditions are tasks B and C
- the correction unit 107 corrects the weight a6 in which the movement time between the locations B and C is set.
- the correction unit 107 increases the weight a6 by a predetermined value ⁇ (for example, 10 minutes). This corresponds to virtually increasing the distance between locations B and C, as shown in FIG. This makes it less likely that both tasks B and C will be assigned to one worker.
- the allocation unit 103 reallocates based on the time index in which the weight a6 is modified. By reassignment, as shown in FIG. 6, an allocation table in which tasks A, B, and D are assigned to worker A and tasks C, E, and F are assigned to worker B is obtained. In this way, the problematic task start time is eliminated.

- step S703 the determination unit 106 determines whether or not the allocation table generated by the allocation execution unit 105 satisfies the determination condition based on the second restriction condition. For example, when a task with the same start time is assigned to one worker, the determination unit 106 determines that the allocation table does not satisfy the determination condition. If the allocation table does not satisfy the determination condition (step S703; No), the process proceeds to step S704.
- step S704 the correction unit 107 corrects the weight related to the task that causes the allocation table to be determined not to satisfy the determination condition. For example, when two tasks with the same start time are assigned to one worker, the correction unit 107 increases the weight set for the movement time between the work places of these two tasks by a predetermined value. After that, the process returns to step S702, and the allocation execution unit 105 reassigns based on the time index with the corrected weight.
- step S705 the output unit 108 outputs the allocation table.
- the output unit 108 displays the allocation table on the display device.
- the allocation table obtained by allocating based on the time index with the corrected weight may be output regardless of whether or not this allocation table satisfies the determination condition.
- the information processing apparatus 100 acquires the first limiting condition and the second limiting condition, which are the limiting conditions for a plurality of tasks, and uses the time index having a plurality of weights determined based on the first limiting condition as a time index. Based on this, multiple workers are assigned to multiple tasks and the assignment result is generated.
- the information processing apparatus 100 corrects the weight related to the task that causes the allocation result to be determined not to satisfy the determination condition, and the weight is corrected. Reassign based on the time index.
- the information processing apparatus 100 obtains an allocation result satisfying the determination condition, the information processing apparatus 100 outputs the allocation result.
- the information processing apparatus 100 may generate an allocation result by solving a linear programming problem using a time index as an objective function.
- the time index is defined by a linear combination of weights. Since the time index is evaluated by the size of the value (magnitude relationship), the quality of the applied restriction condition is clearer than the quality index. Therefore, the ex-post evaluation of the limiting conditions becomes easy.
- a determination condition including an allowance such as a determination condition that the ratio of tasks that do not have a start time to all tasks is suppressed to less than a predetermined threshold value. This makes it possible to eliminate or reduce the occurrence of events for which a solution cannot be obtained in optimization.
- the assigner may wish to assign a combination of tasks that require a short travel time to one worker.
- the movement time between the places E and F is relatively short, and the start times of the tasks E and F are different.
- the correction unit 107 may reduce the weight a15 for which the movement time between the locations E and F is set by a predetermined value (for example, 5 minutes). By reducing the weight a15 , tasks E and F can be easily assigned to the same worker. In this way, the correction unit 107 may correct the weight based on a positive condition.
- the first limiting condition and the second limiting condition relate to a task.
- the first limiting condition and / or the second limiting condition may include a limiting condition regarding a worker.
- Worker data includes skill data indicating the skill level of each worker.
- Skills are classified into 4 levels: SA, S, A, and B.
- SA, S, A, B in descending order of skill.
- the first restriction condition includes the working time for each skill level in each task. For example, the working time of task A is set to 30 minutes for skill level SA, 35 minutes for skill level S, 40 minutes for skill level A, and 45 minutes for skill level B.
- the second limiting condition includes the skill level of the worker, and the determination condition includes the condition that the pair of workers having the skill level B is prohibited from being assigned to one task. For example, when two workers having a skill level of B are assigned to the task A, the correction unit 107 increases the weight in which the work time of the skill level B in the task A is set. This prevents the generation of assignment results that perform a specific task only by the trainee (worker with low skill).
- the correction unit 107 increases or decreases the weight by a predetermined value.
- the correction unit 107 may correct the weight using a tolerance value described later.

- the degree of reflection refers to the ratio at which the second restriction condition is reflected in the allocation table.
- the reflection degree refers to the ratio of the tasks that do not have the start time to all the tasks.
- FIG. 9 shows an example of an allocation table in which nine tasks are assigned to three workers. In the example of FIG. 9, tasks B and C having the same start time are assigned to the worker A, and tasks E and F having the same start time are assigned to the worker B.
- the tolerance determination unit 801 classifies a plurality of allocation tables into three classes.
- the first class classifies allocation tables with a reflection range of 0 to 30%
- the second class classifies allocation tables with a reflection range of 31 to 70%.
- allocation tables with a degree of reflection in the range of 71 to 100% are classified.
- the permissible value determination unit 801 determines the permissible value based on the allocation table classified into the class having the largest number of allocation tables (number of data). By determining the permissible value based on the allocation table classified in the class having the largest number of allocation tables (number of data), it is possible to set the permissible value close to the interval of the assigners.
- the permissible value determination unit 801 determines the largest value among the time index values for which the restriction conditions cannot be reflected in the allocation table classified into the class having the largest number of allocation tables as the permissible value.

- the largest of the allowable value candidates is adopted as the allowable value.
- the permissible value thus obtained is the upper limit of the value permissible by the assignor, and enables the allocation according to the sense of the assigner.
- the permissible value determination unit 801 notifies the correction unit 107 of the determined permissible value.
- the permissible value may be determined by a method other than the above method.
- the permissible value may be a value obtained by subtracting the average moving time of all the sections excluding the section covered by the start time from the average moving time of the section covered by the start time.
- the average travel time of the section covered by the start time is obtained by dividing the total travel time of the section covered by the start time by the number of sections covered by the start time.
- the average travel time of all sections excluding the section covered by the start time is calculated by dividing the total travel time of the sections other than the section covered by the start time by the number of sections excluding the section covered by the start time. It can be obtained by. If a negative tolerance is obtained, the tolerance may be calculated based on the above method.

- the correction unit 107 corrects the weight a6 corresponding to the movement time between the place B and the place C.
- the correction unit 107 corrects the value of the weight a6 to the permissible value. For example, when the movement time between the place B and the place C is 10 minutes and the allowable value is 20 minutes, the correction unit 107 corrects the weight a6 to 20 minutes.
- the correction unit 107 increases the weight a6 by the difference between the travel time between the place B and the place C and the allowable value. If the travel time between place B and place C is equal to or exceeds the permissible value, the correction unit 107 does not correct the weight a6 . For example, if the travel time between location B and location C is 30 minutes and the permissible value is 20 minutes, the weight a6 is maintained at 30 minutes. If neither weight is modified, the same allocation table will be obtained if the allocation is made again. Therefore, if none of the weights is modified, the output unit 108 may output the obtained allocation table.

Abstract
Description
図1は、一実施形態に係る情報処理装置100を概略的に示している。情報処理装置100は、実行すべき複数のタスクへの複数の作業者の割り当てを行うものである。図1に示すように、情報処理装置100は、タスクデータ取得部101、作業者データ取得部102、割当部103、出力部108、タスクデータ記憶部111、及び作業者データ記憶部112を備える。情報処理装置100はサーバやパーソナルコンピュータなどのコンピュータにより実施され得る。
f(x)=a1x1+a2x2+・・+anxn ・・・(1)
ここで、aiは重みであり、xiは変数である。第1制限条件がタスクの作業場所間の移動時間である場合、重みaiは2つのタスクの作業場所間の移動時間であり、時間指標は作業者の移動時間の合計を表す。第1制限条件として作業場所間の移動時間を用いる場合、全作業員が同じ移動手段(例えば徒歩)で移動することを想定した割り当てが可能となる。作業場所間の移動時間は作業場所間の距離に依存する。このため、作業場所間の移動時間に代えて作業場所間の距離が使用されてもよい。
次に、情報処理装置100の動作について説明する。
以上のように、情報処理装置100は、複数のタスクに関する制限条件である第1制限条件及び第2制限条件を取得し、第1制限条件に基づいて決定される複数の重みを有する時間指標に基づいて複数のタスクに対する複数の作業者の割り当てを行って割当結果を生成する。割当結果が第2制限条件に基づく判定条件を満たさない場合、情報処理装置100は、割当結果が判定条件を満たさないと判定された要因となるタスクに関連する重みを修正し、重みが修正された時間指標に基づいて割り当てを再度行う。情報処理装置100は、判定条件を満たす割当結果を得ると、その割当結果を出力する。
割当者は、短い移動時間を要するタスクの組み合わせを1人の作業者に割り当てることを望むことがある。上述の参照例では、場所E、F間の移動時間が比較的に短く、タスクE、Fの開始時間が異なる。この場合、タスクE、Fが同じ作業者に割り当てられることが望ましい。修正部107は、場所E、F間の移動時間が設定された重みa15を所定値(例えば5分)だけ低減してよい。重みa15を低減することにより、タスクE、Fが同じ作業者に割り当てられやすくなる。このように、修正部107はポジティブな条件に基づいて重みを修正してもよい。
