B. System flow
Figure 11 shows the flow of the automatic farm work scheduling system. After a planting/harvest date is input, Processes 1 to 3 are carried out to develop and output schedule data.
Process 1. Calculating number of days required until harvest Based on the predictive model obtained by combining two approximate straight lines, as described in Section 3.1 above,the number of days required until harvest is calculated from the input planting/harvest date.
Process 2. Calculating the harvest/planting date If a planting date is input, a harvest date is calculated by adding the number of days calculated in Process 1 to the planting date. If a harvest date is input, a planting date is calculated by deducting the number of days calculated in Process 1 from the harvest date.
Process 3. Calculating other work dates By registering other tasks and when they take place, in terms of how many days after the planting date, the work days for such tasks will be calculated and shown in the schedule data.
