The aim of this study is to minimize the total distance travelled by the examiners of college entrance examination committee, from their homes to the designated schools, such that the examiners are assigned to each school satisfying certain criteria. A network model is used and the Out-of-Kilter algorithm is applied to solve the examiner-examinee assignment problem. The result is proved to be fairly adequate not only in this problem, but also to the similar situations encountered in, say, school-grouping of junior/senior high schools, and an administration district allocation problem, etc.

The competition for water for municipal, industrial and agricultura and agricultural uses is growing keener as the world fooe and energy crises are intensifying. It is therefore becoming important how systems engineering techniques can be used to plan effectively for the future development of water supply and waste water management systems in a regional area. The feasible direction method and the out-of-kilter algorithm enable us to find the least-cost mix of alternative allocation networks. The interaction between land use patterns and urban water resources, and the environmental impact of alternative policies are discussed.
