A Distributed Computation Model for Marketable Quality and Profitability Considering Unfair Relationship

In this paper, we provide an evaluation method for both: the quality aspect of corporations (marketable quality) and the profitability. We define the corporation rate of operation and profitability. Based on these definitions, we present a model to identify the profitability function considering the rate of operation at the break-even point. This function is considered as the marketable quality indicator from the viewpoint of a fair relationship between producers and consumers. Then, we apply the real values of some leading manufacturing corporations in Japan to our proposed model to analyze its accuracy. From the analysis, we concluded that the theoretical and real standard values of the marketable quality indicator were both 0.6 (that is 60%). We considered the theoretical standard value of the rate of operation as a function of marketable quality indicator for the values greater than the marketable quality indicator and obtained a profitability function. In this function, the profitability gradually increases due to the increase in marketable quality by considering the theoretical standard value as a parameter. This kind of relationship is considered as a standard relationship between marketable quality and profitability. We presented a theoretical distribution of profitability by the proposed profitability function and the theoretical distribution of marketable quality indicator. We found out that the proposed model gives a good approximation of the economical trends of Japanese corporations. Finally, we verified that the proposed fair relationship is a better considered relation than the unfair relationships
