Dislocation is defined as the change between discrete sequential locations of critical materials such as special valves or fabricated items, on a large construction project. Dislocations of construction materials on large sites represent critical state changes. Detecting these dislocations in a noisy information environment where low cost Radio Frequency Identification tags are attached to each piece of material, and the material is moved sometimes only a few meters, is the main focus of this study. We propose in this paper a method based on the Transferable Belief Model (TBM) to estimate materials locations and detect dislocations. This method has been implemented and real experiments were carried out. The results of these experiments show the ability of the proposed method to track the materials.
