The operations research for mechanizing transportation was performed based on results of harvesting and transporting of cucumbers and green peppers in vinyl houses. The results were as follows:
(1) The average time for harvesting cucumbers per container was 5 minutes, the standard deviation was 2 minutes and the frequency distribution for harvesting time became a normal distribution.
(2) The average quantity of harvested cucumbers per container was 6kg, the standard deviation was 3kg and the frequency distribution for the quantity was a normal distribution.
(3) As a result of the operations research, the transporting mechanization of cucumbers was necessary when the area of a vinyl house was over 20a.
It required that the carring implements would transport about 50kg of load at 0.3-0.4m/s.
(4) The transporting mechanization of green peppers was necessary when area of vinyl house was over 40 a.
It required that the carring implements would transport about 25kg of load at 0.2-0.3m/s.
