A plurality of trough displacement characteristics and drive signals for driving a drive unit 26 for a trough 25 are determined in association with each other and the speed of transport of the articles M transported by the trough 25 having one of the trough displacement characteristics is also determined. Accordingly, a plurality of relationships between the transport speed of the articles M and the drive signal of the drive unit 26 can be determined and, based on these relationships and merely by inputting a target speed to be attained by the articles M, the drive signal for the drive unit 26 can easily be selected which enables the speed of transport of the articles M to attain the target speed. Also, since a travel quantity characteristics indicative of a correspondence between the quantity of travel of the articles and the driving time of the trough 25 with respect to each of parameters of the plural coefficients of kinetic friction mu is determined, the quantity of travel of the articles M with respect to the driving time of the trough 25 can be grasped with respect to the plural coefficients of kinetic friction mu taken as a parameter. Based on this, the coefficient of kinetic friction mu between the desired trough 25 and the articles M can easily be obtained from the quantity of travel of the articles measured by actually driving the trough 25 for a predetermined time to transport the article M.
