Farm Field Management Apparatus, Farm Field Management Method, and Storage Medium

A method for managing a managed area including at least one farm field by a farm field management apparatus:

• wherein the farm field management apparatus is configured to hold:
• resource information, which indicates resources, and which indicates, for each of the resources, a task carried out by the resource and per-unit time utilization cost of the resource;
• and
• farm field information, which indicates a quantity of a crop grown in each of the at least one farm field and a unit price of the crop,
• wherein the resources includes a resource that is used to carry out a harvest task in the at least one farm field, and
• wherein the method comprising:
• generating, by the farm field management apparatus, a plurality of task plan candidates;
• in the generation of each of the plurality of task plan candidates, selecting, by the farm field management apparatus, at least one task that includes harvest task in the at least one farm field from the resource information, selecting, by the farm field management apparatus, for each selected task, a resource that is used to carry out the selected task from the resource information, determining, by the farm field management apparatus, for each selected task, a task time within a predetermined period in which the selected task is carried out, include the selected task, the selected resource, and the determined task time in each of the plurality of task plan candidates;
• obtaining, by the farm field management apparatus, information about a harvest impeding factor that is predicted for a harvest time of each of the plurality of task plan candidates;
• calculating, by the farm field management apparatus, an income from a harvest of each of the plurality of task plan candidates, based on a relevant piece of the harvest impeding factor information, and on the quantity and unit price of each crop indicated by the farm field information;
• and
• calculating, by the farm field management apparatus, task cost of each of the plurality of task plan candidates based on a resource utilization period of the resource included in each of the plurality of task plan candidates, and on the utilization cost indicated by the resource information.

A computer-readable non-transitory recording medium having stored thereon a program for causing a computer to manage a managed area including at least one farm field,

• wherein the computer is configured to hold:
• resource information, which indicates resources, and which indicates, for each of the resources, a task carried out by the resource and per-unit time utilization cost of the resource;
• and
• farm field information, which indicates a quantity of a crop grown in each of the at least one farm field and a unit price of the crop,
• wherein the resources includes a resource that is used to carry out a harvest task in the at least one farm field, and
• wherein the program causing the computer to execute:
• a procedure of generating a plurality of task plan candidates;
• a procedure of, in the generation of each of the plurality of task plan candidates, selecting at least one task that includes harvest task in the at least one farm field from the resource information, selecting, for each selected task, a resource that is used to carry out the selected task from the resource information, determining, for each selected task, a task time within a predetermined period in which the selected task is carried out, and including the selected task, the selected resource, and the determined task time in each of the plurality of task plan candidates;
• a procedure of obtaining information about a harvest impeding factor that is predicted for a harvest time of each of the plurality of task plan candidates;
• a procedure of calculating an income from a harvest of each of the plurality of task plan candidates, based on a relevant piece of the harvest impeding factor information, and on the quantity and unit price of each crop indicated by the farm field information;
• and
• a procedure of calculating task cost of each of the plurality of task plan candidates based on a resource utilization period of the resource included in each of the plurality of task plan candidates, and on the utilization cost indicated by the resource information.
