The actual conditions of the auctions to sell fruits and vegetables were investigated in April, 1976 at the Central Wholesale Market of Gifu City. The needed time for every product to be knock down in the auction was analyzed by Hayasi's Quantification Scaling Type 1 in relations with 19 factors in number that seemed to affect the time closely. The results were as follows:
1. The coefficients of the multiple correlation, which meant the estimated accuracies of the times in factor analysis, were 0.622 in fruits and 0.539 in vegetables.
2. The factors had a great influence on the time in order of the following.
Vegetables: the day of the week, amounts of goods to be sold on the day, amounts on the day before, the number of persons taking part in the auction and the weather.
Fruits: amounts of goods on the day, the day of the week, the weather, the prefecture of production and the number of persons.
3. Amounts of goods on vegetables had an effect of making the time shorter if the amounts on the day were less than on the day before. But on fruits, that had a reverse effect.
4. The times for both fruits and vegetables to be knock down were the shortest on the cloudy day, and on the rainy day were the longest.
5. The times were the shortest on Monday, and on Saturday were the longest.
6. If the same lot of fruit was bought together within 5 persons in number, the more the number was, the shorter the time was. But in case of vegetables, the influence on the time was not clear.
7. Fruits shipped from long distance were knock down in a short time.
8. The buyer had an effect of making the time shorter than the retailer joining in the auction.
9. In the auctions of vegetables, the goods classified as the first grade on the quality were bought in a short time, but in the auctions of fruits, the times for the goods classified as the second grade were almost as short as the times for the goods classified the first. On the other hand, the times for vegetables classified as the smaller size (3S-2S) were shorter than the times for vegetables classified as the bigger size (2L, 3L), but the times for the fruits were reverse.
