The BOCIM method (bottleneck-focused continuous improvement) has been designed to support the optimum adaptation of a local water resources management depending on regional conditions to ensure a sustainable supply of water. Being an interdisciplinary approach, the BOCIM method tries to take into account all the factors affecting the water supply. Geared to solving water problems, it is used to: identify and solve whatever the core problem happens to be in a regional water system by applying the bottleneck-concentrated strategy (Mewes in Orell Füssli Management, 112 p, 2000); replace the fragmented project-based approach with continuous improvement; run a management system-orientated quality management standard (e.g. ISO 9001).  相似文献

The development of methods for the construction of stochastic, dynamical models for intra-year irregularity of the Earth’s rotation is considered. A correlational model based on harmonically additive and parametrically random, colored and broadband, gravitational-tidal perturbations from the Sun and Moon is developed. One-dimensional and multi-dimensional characteristic functions are found for the case of Gaussian and non-Gaussian colored and broadband fluctuations in the irregularity of the Earth’s rotation. Examples of computer modeling of the irregularity in the Earth’s rotation based on a priori and a posteriori IERS data are presented.  相似文献

Some current methods for the calculation of the geogenetic depth are based on the hydrostatic model, it is induced that the depth in certain underground place is equal to the pressure divided by the specific weight of rock, on the assumption that the rock is hydrostatic and overlain by no other force but gravity. However, most of rock is in a deformation environment and non-hydrostatic state, especially in an orogenic belt, so that the calculated depth may be exaggerated in comparison with the actual depth according to the hydrostatic formula. In the finite slight deformation and elastic model, the relative actual depth value from the 3-axis strain data was obtained with the measurement of strain including that of superimposed tectonic forces but excluding that of time factor for the strain. If some data on the strain speed are obtained, the depth would be more realistically calculated according to the rheologicai model because the geological body often experiences long-term creep strains.  相似文献
