Building the behavioral model for each circuit block is an efficient approach for mixed-signal system verification. If an automatic model generator is available to extract the required behavioral model from the given circuit netlist, it is useful for designers to reduce the extra efforts. Instead of modeling the relationship between circuit inputs and outputs directly, this paper proposes a divide...
The behavior of a function call statement is decided by its called function, and it is hard to judge the purpose simply from the function call statement. How to simulate the function call is the key part for the accurate symbolic execution. This paper puts forward a path-sensitive function modeling method, in which the definition of stub function is generated according to the calling context. Experiments...
PSS/E is a power system simulation and analysis software commonly used by operational department, which is mostly applied to analyze single case based on artificial operation mode model. PSS/E application mode that API secondary development is used to simulate and control full physical model is proposed in this paper. Full model of power grid is automatically created based on CIM/E model file that...
This paper discusses dynamic alliance (DA) as a form of global supply chain (GSC) and how to develop its quality risk control technology based on 5M1E analysis through fuzzy relation model. A solution method based on genetic algorithm (GA) is proposed to obtain the solution of the proposed model. Finally, a case study of a large-scale water conservancy and hydropower construction project is used with...
The mobility allowance shuttle transit (MAST) system is a hybrid transit system in which vehicles are allowed to deviate from a fixed route to serve flexible demand. A mixed integer programming (MIP) formulation for the static scheduling problem of multi-vehicle MAST (m-MAST) system is proposed in this paper. Based on the MIP formulation, we analyze the impacts of time headways between consecutive...
This paper focuses on a handling system of container port which used the technics of Quay Crane, Container Truck and Yard Crane. Then with the simulation software of ARENA, we build a simulation model for this system, and make an optimization to find the optimal allocation of equipments under the constraints of a certain equipment utilization and a minimum operation time. With the conclusion in our...
Since the cash flow information can be applied well in the evaluation of enterprise's financial situation, In this paper, the cash profit, which is the information connotation of cash flow, is a basis of financial evaluation index system and main criteria to define the distress companies. Two early warning models based on cash profit and traditional accounting profit separately are set up by logical...
Tunnel excavation design is an important content in the civil engineering, many researches are done based on the linear failure criterions by the analytical solution and numerical solution, but seldom researches are done to apply the nonlinear failure criterion in describing the surrounding rock mass after tunnel excavation, although nonlinear failure criterion shows great advantages over the linear...
Measuring multi-dimensional linear displacements in large scale range with high precision is always focused on by researchers. This paper presents the results of simulation analysis on characteristics of a planar capacitive sensor (PCS), which is proposed for X and Y direction linear displacement measurement by measuring the periodic change of capacitance between two periodic plates, one fixed (i...
The superfluous force seriously affects the dynamic load precision of the electro-hydraulic load simulator. Aiming at this question, the work principle of the electro-hydraulic load simulator was analyzed, and the bond graph models of the flow servo valve, hydraulic cylinder and load were established. These models sufficiently contain the higher-order nonlinear dynamic character of the electro-hydraulic...
The paper takes an empirical study of the cooperation of small logistics companies, its consequence, motivation and interrelationship, using structural model with the analysis of primary elements. Result shows that any input in or devotion to the cooperation among small logistics companies will influence each other in strategic value, economic benefits and intangible assets and equity, subsequently...
