Abstract
We descrived the use of computerized layout model as design aids in developing alternative layout designs. Input data to the model are the following : 1) shape and size of each rectangle room. 2) types of room, movable, fixed, semimovable x, semimovable y and movable within a territory, and bar type comonent. 3) association chart of c_<ij> which denotes communication frequency between room i and j. Rooms are located adjacently by heuristic methoh so as to minimize the total of the product of c_<ij> and the Euclidian distance d_<ij>, taking into account of the site. The total force on room i in the x and y direction is given by the equations, [numerical formula] where [numerical formula] U_R is the magnitude of the repulsion force between the two rooms whose frequency of communication is 0. R_R is a constant ratio of a tension and a repulsion force. M is a number of rooms total (fixed, movable, and semimovable). L is a number of components. Following formulas present the mathematical concept of forced directed location of moveable rooms. Try to find location to these equations by the method of successive approximation. U_v is a constant to move every room qradually. [numerical formula][numerical formula] The location procedure is broken down into three phases "forced directed location phase", "room overlap resolution phase" and "convergence phase". All boundaries between rooms being regarded as potential paths are considered a circulation path network for this layout. A vertex of a room is considered a node of the network. Find paths of minimum total length between every two given rooms by the Dijkstra Method. These paths construct the path communicating every room. Rooms along the path are moved to give the dimension to the path.
