To accurately characterize and effectively control the two-echelon inventory system of a telecom operator, this paper establishes a model consisting of a distribution center with multiple warehouses, with an objective function for the optimization of average total inventory and delivery costs. And the model determines two-echelon distribution system's regular stock replenishment policy, safety stock...
Fixed-point simulation is extremely important in the design of fixed-point FPGAs. Float-point simulation is used to verify the arithmetic, while the fixed-point simulation is adopted to evaluate performance and verify the implementation. The design of high-precision system by FPGAs must focus on the fixed-point simulation to reduce the error acceptable even to zero. Based on the analysis of fixed-point...
Regional forest resource has multi attributes of global and local public good. Based on the empirical research from relative available data in China and the General Linear Mixed-effects Models, this paper finds the regional forest resource has a significant effect on the life expectancy. So the government, whose objective function is to maximize the resident social welfare, should bring the policy...
