Become.

Component a 'first converted rating data a representing the evaluation of the _k' Category C _'k is the category C' of the first evaluation data a representing the evaluation of the first evaluation item A _i belonging to _k When the first evaluation item A _i belongs to the category C ′ _k and includes the component a _i as a factor, the first evaluation data a representing the evaluation of the one first evaluation item A _i a component _{a i} constant multiple alpha _i a _i of the category C _'k into two or more first endpoint _a i1, · · _·, the two or more first endpoint _{if a im} belongs a _i1, ···, components _a i1 of the first evaluation data a representing each of evaluation of the _{a im,} ···, is a linear combination _{α i1 a i1 + ··· + α} im a im of _{a im.} Category C _k 'component b of the second converted evaluation data representing evaluation for _k' is the category C 'component of the second evaluation data representing evaluation for the second evaluation item B _j belonging to _k b _j hints as a factor, the category C 'where one second endpoint B _j belongs to the _k-component b _j of the second evaluation data representing evaluation for the one second endpoint B _j a constant multiple beta _j b _j, category C 'second evaluation of two or more _k item _{B j1,} ···, a second evaluation two or more such of _{if B jn} belongs items _{B j1,} · _.. , B _jn are linear combinations β _j1 b _j1 +... + Β _jn b _jn of the components b _j1 ,..., B _jn of the second evaluation data b respectively representing the evaluations.

For example, the first evaluation items A ₁ , A ₂ , A ₃ , A ₄ , A ₅ and A ₆ , and the second evaluation items B ₁ , B ₂ , B ₃ , B ₄ , B ₅ and B ₆ are categories. C ′ _k (k = 1, 2, 3), and the first evaluation items A ₁ , A _2, and A ₃ , and the second evaluation item B ₁ , as shown in Expression (1). , B ₂ and B ₃ belong to category C ′ ₁ , and the first evaluation item A ₄ , and the second evaluation items B ₄ and B ₅ belong to category C ′ ₂ as shown in equation (2). Let us consider a case where the first evaluation items A ₅ and A ₆ and the second evaluation item B ₆ belong to the category C ′ ₃ as shown in Expression (3).

In this case, as represented in Equation (4), components a category C 'first converted evaluation data a representing the evaluation of _{1' 1,} category C 'first evaluation belonging to _a It is a linear combination α ₁ a ₁ + α ₂ a ₂ + α ₃ a ₃ of the components a ₁ , a ₂ and a ₃ of the first evaluation data a representing the evaluations of the items A ₁ , A ₂ and A ₃ respectively. Component a 'first converted evaluation data a representing the evaluation of _2' Category C _'2 is the category C' of the first evaluation data a representing the evaluation of the first endpoint A ₄ belonging to the ₂ it is a constant multiple alpha ₄ a ₄ component _{a 4. 3} 'components a first converted evaluation data a representing the evaluation of the _3' category C is first evaluated respectively representing evaluation for the first endpoint A ₅ and A ₆ belonging to the category C _'3 is a linear combination _{α 5 a 5 + α 6 a} 6 component data a _{a 5} and component _{a 6.} However, the weighting factor α _i multiplied by the component a _i of the first evaluation data a satisfies α _i > 0 (i = 1, 2, 3, 4, 5, 6).

Moreover, as represented in Equation (5), ₁ 'component b of the second converted evaluation data b representing the evaluation of _1' category C, the second evaluation belonging to the category C _'1 Item B ₁ , B _2, and B ₃ are linear combinations β ₁ b ₁ + β ₂ b ₂ + β ₃ b ₃ of the components b ₁ , b _2, and b ₃ of the second evaluation data b representing the evaluations, respectively. The component b ′ ₂ of the second converted evaluation data b representing the evaluation for the category C ′ ₂ is the _second evaluation representing the evaluation for the second evaluation items B ₄ and B ₅ belonging to the category C ′ ₂ respectively. This is a linear combination β ₄ b ₄ + β ₅ b ₅ of the components b ₄ and b ₅ of the data b. Category C ₃ 'component b of the second converted evaluation data b representing the evaluation of _3', the components of the second evaluation data b representing the evaluation of the second endpoint B ₆ belonging to the category C _'3 is a constant multiple β ₆ b ₆ of b _6. However, the weight coefficient β _j multiplied by the component b _j of the second evaluation data b satisfies β _j > 0 (j = 1, 2, 3, 4, 5, 6).

  In the following step S113, the compatibility calculator 172 determines the first and second workers based on the passed first and second converted evaluation data a 'and b'. Computation is performed to calculate the compatibility between the human relationships, and compatibility data representing the calculated compatibility is passed to the compatibility data storage unit 172. The compatibility data storage unit 172 receives the passed compatibility data and stores the received compatibility data.

  The compatibility is represented by, for example, an inner product a ′ · b ′ of the first converted evaluation data a ′ and the second converted evaluation data b ′, which is calculated by Expression (6).

  The compatibility between the first worker A and the second worker B is considered to be better as the inner products a 'and b' are larger. For this reason, the compatibility between the first worker A and the second worker B is determined by the vector of the first converted evaluation data a ′ and the vector of the second converted evaluation data b ′. The smaller the angle is, the better it is. The larger the vector of the first converted evaluation data a 'is, the better it is. The vector of the second converted evaluation data b' is Larger sizes are considered better. As a result, the compatibility between the first worker A and the second worker B is such that the first worker A and the second worker B make a positive evaluation of each other. Considered to be good.

However, when having a first converted evaluation data a 'component a k-th' _k, and any negative values of _k 'component b of the k' of the second converted evaluation data b is the the product of the _k 'component b of _k and the k' component a k, -1 is multiplied. For example, when k = 1, the product of the first component a ′ ₁ and the first component b ′ ₁ is multiplied by −1, and the inner product a ′ · b whose compatibility is calculated by Expression (7) '. Thereby, the compatibility between the first worker A and the second worker B is such that the first worker A and the second worker B make a negative evaluation of each other. Considered not good.

  Here, the evaluation items of "like", "interesting", "respect" and "trust" belong to the category of "emotion", and the evaluation value representing the evaluation of each evaluation item is a perfect score of 10 points. The first evaluation data a representing the evaluation of the worker A with respect to the second worker B is (like, trust) = (5,5), and the evaluation of the second worker B with respect to the first worker A Is assumed to be (respect, interesting) = (4, 1). In this case, since the evaluation items of “like”, “interesting”, “respect” and “trust” belong to the category of “emotion”, when the weighting coefficient multiplied by each evaluation value is set to 1, the first The converted evaluation data a ′ and the second converted evaluation data b ′ are expressed by Expressions (8) and (9), respectively.

  From the first converted evaluation data a 'and the second converted evaluation data b' represented by the equations (8) and (9), it is derived that the inner product representing the compatibility has a value of 50. Since the best value of the inner product representing compatibility is 400, if the inner product representing compatibility has a value of 50, the compatibility between the worker A and the worker B cannot be said to be good.

To the unit 202. Further, the combination assigning unit 204 receives the combination evaluation values of all the passed combinations. Further, the combination assigning unit 204 selects one combination from all the selected combinations based on the received combination evaluation values of all the combinations, and evaluates the combination evaluation value of the selected one combination and the property on which the work is performed. Then, a work schedule is created based on the travel time to the server and the existing work schedule, and the created work schedule is passed to the work schedule storage unit 203.

12 Operation of Work Schedule Creation Unit FIG. 11 is a flowchart illustrating the operation of the work schedule creation unit provided in the work schedule creation device according to the first embodiment.

  In step S131 illustrated in FIG. 11, the combination assignment unit 204 reads the work data from the execution work storage unit 181 and assigns the highest priority to a plurality of work IDs included in the read work data. Select an ID. Further, the combination assignment unit 204 receives the passed combination data, and selects a combination in which the worker is combined with the work identified by the selected work ID included in the received combination data. Thereby, the combination assignment unit 204 selects all combinations in which the worker is combined with the work having the highest priority. Further, the combination assignment unit 204 passes all the selected combinations to the combination evaluation value calculation unit 202.

  In the following step S132, the combination evaluation value calculation unit 202 reads compatibility data from the compatibility data storage unit 173, reads work time data from the work time storage unit 200, and receives all passed combinations. Further, the combination evaluation value calculation unit 202 calculates the combination evaluation values of all the passed combinations based on the read compatibility data and the operation time data, and combines the calculated combination evaluation values of all the combinations into the combination assignment unit 204. Pass to.

  The combination evaluation value of each combination is, when a plurality of workers are combined in the work in each combination, the total work time required for the plurality of workers to perform the work, Is the corrected work time corrected by the compatibility between. Therefore, in the combination evaluation value of each combination, compatibility between the plurality of workers is considered.

When a plurality of workers constituting the set M are combined with the work w in the combination, the combination evaluation value I _{w, M} is an individual required for the worker m∈M belonging to the set M to perform the work w. Is expressed by equation (10) using the working time T _{m, w} of

The work time T _{m, w} is, as represented by the equation (11), the individual work time t _{m, w} required for the worker m to perform the work w, which is included in the work time data, compatibility data s _m representing the compatibility between the workers m'∈M other than m and workers _{m, m '=} s _m', obtained by correcting the _m. The parameter μ appearing in the equation (11) is an arbitrary parameter for scaling the working time tm _{, w} and the compatibility data sm _{, m ′} . The above-mentioned inner product can be used as the compatibility data sm _{, m '} .

  In the following step S133, the combination allocating unit 204 receives the passed combination evaluation values of all the combinations and, based on the received combination evaluation values of all the combinations, determines the minimum combination evaluation value from all the selected combinations. Select the combination that has.

  In the following step S134, the combination assignment unit 204 reads the travel time data from the travel time storage unit 201, reads the existing work schedule from the work schedule storage unit 203, and based on the read travel time data and the existing work schedule. Then, it is determined whether or not there is a vacant time zone to which the work can be assigned to the worker combined with the work in one selected combination. If it is determined that there is a free time zone, step S136 is executed. When it is determined that there is no free time zone, step S134 is executed again after step S135 is executed.

  In step S135, the combination assignment unit 204 selects a combination having a combination evaluation value next to the combination evaluation value of the most recently selected combination from all the selected combinations.

  By executing steps S134 and S135, the combination having the minimum combination evaluation value is selected from the combinations in which there is a free time zone in which the work can be allocated to the worker combined with the work. Therefore, under the constraint that the work can be assigned to the worker combined with the work in the combination, the smaller the combination evaluation value of each combination, that is, the shorter the corrected work time of each combination, Each combination is easier to select.

  In step S136, the combination allocating unit 204 creates a work schedule in which the work is allocated in the idle time zone of the worker combined with the work in the most recently selected combination, and stores the created work schedule in the work schedule storage unit. Hand over to 203. The work schedule storage unit 203 receives the passed work schedule, and stores the received work schedule.

  The work IDs “W001” and “W002” included in the work data described in the table 210 are associated with priorities “80” and “60”, respectively. In addition, in the combinations “W001 $ (M001, M002)”, “W001 $ (M001, M003)” and “W001 $ (M002, M003)” included in the combination evaluation value data described in the table 211, A worker is combined with the work identified by the ID “W001”, and in the combinations “W002 @ M001” and “W002 @ M002” included in the combination evaluation value data, the work identified by the work ID “W002” Workers are combined.

Therefore, one combination having the minimum combination evaluation value “54.45” is the combination “W001⇔ (M002, M003)”. Therefore, the combination assignment unit 204 selects one combination “W001 @ (M002, M003)”.

  Further, in the existing work schedule described in the table 213, there is a free time zone common to the workers identified by the worker IDs “M002” and “M003” in the afternoon of August 2. The length of the free time zone is longer than the total of the combination evaluation value “54.45” of one selected combination “W001 @ (M002, M003)” and the travel time data. Therefore, the work identified by the work ID “W001” can be assigned to the idle time zone. Therefore, the combination assignment unit 204 assigns the work identified by the work ID “W001” to the worker identified by the worker IDs “M002” and “M003”.
