This is an idealized environmental condition in which the magnitudes of all the consequences of the decision and all the system parameters are distinctly known (deterministic). There is only one possible environmental state, the system response will also be one and unique for a particular decision (e.g. the system has single attribute or dimension) and the decision making is simple and direct. If more than one attribute exists the various attributes have to be weighed against each other.
One example of such decision making could be construction scheduling. The objective is to absorb the demand fluctuations by some combination of hiring (or lay off), subcontracting, overtime and incentives etc. Even when the demand environment (resource requirement) is known with certainty (deterministic), there can be infinite strategy options which combine different levels of hiring, fixing overtimes etc. The objective is to select a strategy which minimizes the operation cost.
