A Value-Driven Approach to Capture Unintended Consequences Impacting Mission Success

The Relationship Between Goal-Function Trees and Value Models

“…[66] True preference(s) of the stakeholders. [59] An intrinsic property of the engineering system related to an organization's philosophical or technological model and may consist of more than simple economic metrics such as cost. [64] Value Model…”

“…[3] (objective function) a function of attributes, which in turn are functions of design variables; used to aid in the decision-making process to reflect the true preference of the stakeholders. [59] value function that represents the true preference of the stakeholder(s)... formed from multiple attributes, that represents the preferences of a DM a priori and then uses computational means to generate alternatives. [64] Objective Function…”

“…[3] Where the preference of system design is reflected, and the constraints represent design requirements. [59] An aggregation function that forms from many lower-level attribute functions. [64] Attribute Lowest level criteria that serve to explicate and operationalize higher level values and concerns.…”

“…[38] Contribute in some way to value to the system value through some equation [62] Functions of design variables. [59] Are of concern to a decision maker, whose preferences are captured using a value model. [60] Functions of design variables (X) and behavior variables (Y).…”

“…[66] Value is captured through a value function (objective function), which is a function of attributes, which in turn are functions of design variables. [59] Parameters. [3] Table I above demonstrates the unique elements of value models, as well as inconsistencies in definitions by the value model communities.…”
