Comprehensive assessment of sustainable utilization of regional water resources, including three subsystems: social economy, water resources and eco-environment, is a large complicated and systematic evaluating problem. The selection of the index system for the regional sustainable development of water resources was discussed herein. Furthermore, a neural(More)
We consider split panel design efficiency in analysis of variance models, that is, the determination of the cross-sections series optimal proportion in all samples, to minimize parametric best linear unbiased estimators of linear combination variances. An orthogonal matrix is constructed to obtain manageable expression of variances. On this basis, we derive(More)
