| Niagara Mohawk's transmission system described by 4000 X 4000 sparse matrix (~12 nonzero elements in each row) |
| Use to plan and control electrical distribution and to recover from circuit damage |
| NiMo could use small parallel MIMD machine - problem not very big |
| Large teraflop machine could control nation's power? |
| NYNEX currently does not use sophisticated simulations in planning new installations. Has large databases of information to guide simulation |
| All are physical networks with mainly local connections |
