Abstract : Observations of the flow through the arcs in a tree graph are available, and it is required to combine these to provide estimators of the arc flows. An algorithm for estimating the root flow is presented. The algorithm gives linear, unbiased estimators. If the arc-flow observations are uncorrelated, the algorithm gives the linear, unbiased, minimum-variance estimators. The algorithm is shown to be applicable to estimate the flow through an arbitrary arc of the tree. In conclusion, various fields of application of the estimation problems are indicated. (Author)
