*Fixed position layout:-In a fixed position layout the project remains in one place and workers & equipments come to that one work area. Example of this type of project is a ship, a highway, a bridge, a house, and an operating table in hospital room. The techniques for addressing the fixed position layout are complicated by three factors. First there is limited space at virtually all sites. Second, at different stages of a project different materials are needed. Third the volume of materials needed is dynamic.
