The relationships between customer requirements and technical measures are typically resolved by a cross-functional team with
the assumption that the relationships are able to be identified objectively. However, due to the limited knowledge and experiences,
determining the appropriate relationship could be difficult since the decision makers might not have enough information to
evaluate the actual relationship. Moreover, the importance of technical measures is typically expressed in the current time
period. It would be of interest to trace the future trends of technical measures since customer needs are fulfilled by technical
measures. Under such circumstances, a Markov chain model could be an approach to model the relationship and monitor the trends
of technical measures from probabilities viewpoints. With the needed probabilities, the dynamic relationships as well as the
trends of technical measures can be performed by different time periods. Finally, the relationships and future trends of technical
measures can be updated when the new information is available. 相似文献

This paper sets up an endogenous-growth model in which the consumer's preference is subject to habitual consumption, and examines how consumption habits will govern the rate of sustained growth. It is found that the habitual behavior may be either growth-enhancingor growth-reducing, depending upon whether the substitution between intertemporal consumption is inelastic and whether the consumption experience is harmful or beneficial to the agents. It is also found, given that the elasticity of intertemporal substitution is less than unity, that the learning speed of consumption habits has a positive (negative) impact on the balanced-growth rate if the consumption experience is harmful (beneficial) to the agents. 相似文献

This note re-examines two important propositions in the Clarke and Shrestha linear space model. We provide a complete analysis of designing and locating a secondary energy generation facility in the Clarke and Shrestha linear model and clarify two of their propositions. 相似文献

There is a significant positive relation between Tobin's q-ratio and the magnitude of stock market reaction to capital investment announcements. The findings have the following implications for capital investment theory: (i) The results provide evidence substantiating the link between the q-ratio and real investment for industrial firms. For public utilities however, no such link exists, (ii) The study finds that average q and marginal q are correlated but the relation is somewhat more complicated than simple equality as assumed by numerous empirical studies. (iii) The findings suggest that investors can use average Tobin's q-ratio to identify companies with profitable real capital investment opportunities. 相似文献

This note re-examines the stabilities of government financing by (a) treasury bills, and (b) perpetuities. In contrast to Currie and Gazioglou, it is shown that the wealth effect on expenditures plays the same role in the financing by treasury bills and by perpetuities. 相似文献
