In a setting support device, for the existing system groups each include multiple tags, a grouping unit groups the systems that have common tags. A rule extracting unit extracts, for each grouped group, a set rule that is used for environmental setting set in each of the systems on the basis of the environmental setting that is set in the systems belonging to a group. A tag common rule specifying unit specifies a set rule that is common in each tag on the basis of the set rule that is extracted for each group and on the basis of the tags included in the systems belonging to each group. A new rule merging unit creates, by using the set rule specified by each tag, a set rule that is associated with the multiple tags included in a new system.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A non-transitory computer-readable recording medium storing therein a setting support program that causes a computer to execute a process comprising: grouping, for a first system that includes multiple attributes, systems that have common attributes; extracting, for each group grouped at the grouping, a set rule that is used for environmental setting set in each of the systems on the basis of the environmental setting set in each of the systems belonging to a group; specifying a set rule that is common in each attribute on the basis of the set rule that is extracted for each group at the extracting and on the basis of the attributes included in the systems belonging to each group; and creating, by using the set rule that is specified for each attribute at the specifying, a set rule that is associated with multiple attributes included in a second system. 2. The non-transitory computer-readable recording medium according to claim 1, the process further comprises estimating, when a set rule that is common in predetermined attributes is not specified at the specifying, the set rule that is common in predetermined attributes on the basis of a set rule of a group that includes the predetermined attributes, on the basis of a set rule that is common in another attribute that is different from the predetermined attributes included in the group, and on the basis of a set rule that is common in all of the groups. 3. The non-transitory computer-readable recording medium according to claim 1, the process further comprises inputting manually, when a new attribute is included in the multiple attributes that are included in the second system, environmental setting related to the new attribute. 4. The non-transitory computer-readable recording medium according to claim 1, the extracting includes extracting, for each group grouped at the grouping, a set rule that indicates the condition and the definition used for the setting of the parameter that is used for the environmental setting set in each of the systems. 5. A setting support device comprising: a processor; and a memory, wherein the processor executes: grouping, for a first system that includes multiple attributes, systems that have common attributes; extracting, for each group grouped at the grouping, a set rule that is used for environmental setting set in each of the systems on the basis of the environmental setting set in each of the systems belonging to a group; specifying a set rule that is common in each attribute on the basis of the set rule that is extracted for each group at the extracting and on the basis of the attributes included in the systems belonging to each group; and creating, by using the set rule specified for each attribute at the specifying, a set rule that is associated with multiple attributes included in a second system. 6. A setting support method executed by a computer, the method comprising: grouping, for a first system that includes multiple attributes performed by a computer, systems that have common attributes; extracting, for each group grouped at the grouping performed by the computer, a set rule that is used for environmental setting set in each of the systems on the basis of the environmental setting set in each of the systems belonging to a group; specifying, performed by the computer, a set rule that is common in each attribute on the basis of the set rule that is extracted for each group at the extracting and on the basis of the attributes included in the systems belonging to each group; and creating, performed by the computer by using the set rule that is specified for each attribute at the specifying, a set rule that is associated with multiple attributes included in a second system.
