Giving this from-to material flow matrix for an eight-department facility in the table below. The space requirement is given as the table below. The building dimension is given as a 10 by 13 grids, with each grids represents a 10 by 10 unit space. Give the numerical closeness ratings as: A=10,E=5,l=2,0=1,U=0 and X=10 Construct a relationship diagram based on the material flow matrix and then: Use graph-based method to construct the graph that represents the adjacency of a layout, and calculate the efficiency score. (Just need to create the graph)
