The System Approach To Making Management Decisions Under Uncertainty
Table 1: The main approaches to making management decisions in the face of uncertainty
| Approach | Characteristic |
| Deterministic | allows the manager to have almost complete and reliable information regarding the problem being solved and to know exactly the results of alternatives |
| Probabilistic | includes results that are not certain, but the probability of each result is known |
| Theory of Fuzzy Sets | increases the validity of the management decision-making process, since many of the data obtained by collecting opinions on a particular problem cannot be represented by a single number, but represent some verbal assessments |
| Systems approach | based on the following basic principles: systematicity, hierarchy, integrality and formalism, and on some combination of fundamental concepts: system, element, subsystem, external environment, factor, value, usefulness, purpose |
