Based on the above study, a program is developed which calculate the modeled subgrid stresses, and is applied to simulate the turbulent flow in a plane channel. The computational result is compared with the data extracted form a DNS database, and the agreement is satisfactory. A numbers of physical phenomenon has been reproduced in the simulation, including hairpin vortex and counter-rotating rolls in near wall region, intermittent vortex structure, the maximum of pressure clustering in wall area and the high-speed fluid sweep into the low speed fluid, and the ability of the LES to simulate turbulent flow is well shown.

Then, it studies the supply chain management system as a complex system to confirm the state existing during operating of the system. After that, it conducts a probability analysis on the state which the system located by applying supplement variable method, and establishes the model of distributed parameter system in a form of partial differential equations. Combining C0 ? semigroup theory in the functional analysis, it conducts a dynamic analysis on the established mathematical model. Using this method, it obtains the mathematical expression of the dynamic solution and the steady state solution, and proves the uniqueness, non-negativity and the asymptotic stability of the system solution. This dissertation applies the Matlab tool and uses two-step, three-step Simpson integral equation to imitate the condition of system solution. Then, it adds possible mode of failure and the optimization adjustment state to the system, based on which it has established the distributed parameter system model which is described by partial differential system of equations. Combining the functional analysis C0 ? semigroup theory, it studies the established mathematical model, and obtains the mathematical expression of the dynamic solution system and the steady state solution. It has proven the existing of uniqueness of the system solution, the asymptotic stability of system solution and the system solution. In addition, it has lying the theory rationale for further analysis and the research on the optimization of system.
