Abstract
This paper describes the evaluation methods for posture analysis of materials handling in transportation and distribution with vehicle routing. Working postures are expressed with transition matrix and diagram. Signal flow graph and linear equations are also used to express the working posture. To evaluate the working posture, we proposed the fuzzy information theory. The measurements of working posture are evaluated with entropy from information theory. It is very easy to evaluate the materials handling posture. Fuzzy clustering techniques are used to classify the working postures in materials handling. Hierarchic classifications can be represented by the dendrogram which illustrates the fusions or divisions for working posture. Here is shown the relationship between fuzzy posture information theory and fuzzy cluster analysis.
