An application of multiple regression analysis to the greek beer market

The object of this paper is to present a quantitative analysis of the Greek beer industry, through the use of various single regressions. The first part presents the relationship between advertising and sales through disaggregating advertising outlays, media and firm advertised, while a number of indices referring to advertising effectiveness are also estimated. The second part extends the discussion by presenting an illustrative example with regard to the implied duration interval and its importance in advertising. © 1985 Operational Research Society Ltd

Production planning of seasonal demanded products

This paper presents an attempt to find the optimum production rate by factories using seasonally produced raw material. To this effect the Aggregate Production Planning Model suggested by Holt et al. [12], has been applied to a real world case of a factory industrializing agricultural products. Finally, among the feasible solutions applied to this case, the optimum production policy determines the quantities which are forecasted to be sold after the termination of the period of operation of the plant. © 1980, All rights reserved

A quantitative analysis of new car sales and advertising in Greece

The purpose of this paper is to investigate empirically the sales-advertising relationship in the Greek car market which operates in an environment characterized by high inflation and depreciating currency. Car manufactures were grouped for this study in three broad categories according to the cars' country of origin. The results of the analysis suggest that car manufacturers need to reconsider their present advertising strategy by taking into consideration both the effects of advertising on rivals' sales and the customers' attitudes to car sales pricing. © 1990
