    Notizen: Abstract This paper discusses the rationale for the use of additive models involving multiple objectives as approximations to normative analyses. Experience has shown us that organizations often evaluate important decisions with multiple objective models rather than reducing all aspects of the problem to a single criterion, dollars, as many normative economic models prescribe. We justify this practice on two grounds: managers often prefer to think about a problem in terms of several dimensions and a multiple objective model may provide an excellent approximation to the more complex normative model. We argue that a useful analysis based on a multiple objective model will fulfill both conditions—it will provide insights for the decision maker as well as a good approximation to the normative model. We report several real-world examples of managers using multiple objective models to approximate such normative models as the risk-adjusted net present value and the value of information models. The agreement between the approximate models and the normative models is shown to be quite good. Next, we cite a portion of the behavioral decision theory literature which establishes that linear models of multiple attributes provide quite robust approximations to individual decision-making processes. We then present more general theoretical and empirical results which support our contention that linear multiple attribute models can provide good approximations to more complex models.

    Notizen: Abstract Humans are constantly making evaluations about the direction of movement in time of systems perceived as relevant, in terms of whether things are moving to the better or to the worse. The relevant system may be very small or as large as the whole planet earth; evaluations seldom go beyond the solar system. We evaluate things like health, wealth, security, justice, etc. and we have a strange capacity for putting many diverse variables together into a single rough evaluation. Accountants evaluate the state of a balance sheet or position statement quantitatively in terms of dollars; economists evaluate aggregates like the GNP. But almost everyone goes beyond quantification into rough, qualitative evaluations of the total state of a system. The evaluation of overall systems runs into the difficulty that different persons evaluate the same perceived change differently. Nevertheless, there are many processes in society by which differing evaluations are coordinated, even if they are not reconciled. The market is one, politics is another, and the moral order is a third. In large systems we are unlikely to come out with a single answer to even the question of whether things are getting better or worse. But we can identify certain instances where there is wide agreement that a movement is for the worse: the ‘cliffs’-disasters, premature deaths, losses of liberty, etc. We can furthermore specify certain dynamic systems likely to produce these dramatic worsenings, and perhaps do something about them.
