This investigation studies the effect of the retail price and the technical properties of preference ordering of buyers of power saw. According to the model derived, the preference ordering of power saws is due to technical properties xj. If no such restrictions in the function are supposed that could have bearing on the preferences of the buyers, there may be N ! possible combinations, when there are N power saws. If one can presume that each price corresponds with a technical level it is possible that each buyer has an optimum price of his own. The bigger the difference between the optimum and actual price, the less preferred the actual power saw is. In this case one may notice the amount of possible orderings is much less than that based on the model. Thus, the mode may be used.
In this paper some models are presented for cases when only n pieces of the population of N power saws are studied. 16 power saws of differing ages and technical levels were investigated. It was noted that many criteria of technical goodness were positively intercorrelated. The price correlated positively with every criterium used. According to the profile analysis, it was concluded that there were many development lines. For example, the idea of a light and the idea of an effective power saw.
According to the principal component analysis, it seemed obvious that there was little room for one- or two-dimensional preference ordering by the technical properties and price.
