We propose and experimentally test a theory of strategic behavior in which players are cognitively imprecise perceive fundamental parameter with noise. focus on 2 x coordination games, generate multiple equilibria when perception is precise. When adding small amount cognitive imprecision to the model, we obtain unique equilibrium where use simple cutoff strategy. The model further predicts that...

A technique to perform design calculations on imprecise representations of parameters has been developed and is presented. The level of imprecision in the description of design elements is typically high in the preliminary phase of engineering design. This imprecision is represented using the fuzzy calculus. Calculations can be performed using this method, to produce (imprecise) performance par...

Geographic information systems date from the 1960s, when computers were mostly seen as devices for massive computation. Very significant technical problems had to be solved in those early days: how did one convert the contents of a paper map to digital form (by building an optical scanner from scratch); how did one store the result on magnetic tape (in the form of a linear sequence of records r...

It is argued that image measurements should satisfy two requirements of physical plausibility: the measurements are of non-zero scale and non-zero imprecision; and two required invariances, nothing is lost by expanding the image and nothing is lost by increasing the contrast of the image. A model of measurements satisfying these constraints, based on blurring the graph of the incident luminance...

An axiomatic way is given for constructing imprecision indices of lower probabilities. The algebraic structure of linear imprecision indices is described. Necessary and sufficient conditions are found when a linear functional produces a linear imprecision index. The important class of linear symmetric imprecision indices is introduced, and the investigation of its algebraic properties is carrie...
