It is a refo rm in the enterprise management mode, management idea and management method whi ch needs mass fund import, with long period, full of risk, hard to perform and can’t show its effects at once. The essence of the enterprise performing in ERP system is to run a "management engineering", which involves integration of opera tion process. The integration will touch business culture, enterprise system,m eans of operation and the department’s regulatioins amongst the operation conten ts, rights and responsibilities. Totally, the ERP system is the rebuilding of ma ngagement idea, method and means, which needs the common acquaintance from the t op management to the whole stuff.Meantime, it requires a perfect tactic to perfo rm an ERP system. We must confirm a cut-in spot as the right space to start bas ed on the enterprise requirement and the application environment. And to choose a right space decides that the application of ERP system is successful or not. S o, we must make it clear to build which subsystem first, to take the right seque nce for performing all kinds of function modules and the final integrated functi ons . All this prepared work for the implement of ERP system and the management, the recombination and optimization of enterprise management operation flow, ite m management and harmonization, ERP educational training and so on can not be pe rformed well without management consultancy. The effective management consultan cy can lead then implement of ERP system to shorten the executive cycle, to quik en the realization of effect and to harmonize the relationship to the client ent erprises so that to ensure the successful perform of ERP.展开更多

In order to improve it, a novel flatness predictive model via T-S cloud reasoning network implemented by digital signal processor(DSP) is proposed. First, the combination of genetic algorithm(GA) and simulated annealing algorithm(SAA) is put forward, called GA-SA algorithm, which can make full use of the global search ability of GA and local search ability of SA. Later, based on T-S cloud reasoning neural network, flatness predictive model is designed in DSP. And it is applied to 900 HC reversible cold rolling mill. Experimental results demonstrate that the flatness predictive model via T-S cloud reasoning network can run on the hardware DSP TMS320 F2812 with high accuracy and robustness by using GA-SA algorithm to optimize the model parameter.展开更多

In addition, the developed constitutive model was implemented into finite element codes in Abaqus to simulate the tensile deformation. The standard uniaxial tensile tests were carried out. The stress-strain curves from the uniaxial tensile tests show that the stress keeps decreasing after yielding and the yield stress rises with the increasing of the strain rate. It is worth noting that the craze damage is more visible with higher strain rate. The stress-whitening can be seen clearly around the fracture. The uniaxial tensile tests using specially designed specimen with circular holes weakening were performed for the validation of the developed model. The simulation results of the tensile deformation of the hole-weakened specimen suggest that the stress-whitening could be attributed to the equivalent visco-plastic strain. By comparing between the simulation analysis and the experimental results, the proposed model can describe the stress whitening phenomenon with good accuracy.展开更多

This paper presents the design principles and implementation of a layered modeling system known as General-Purpose user-defined Modeling System (GPMS) which provides the user with multiple accesses to build a simulation model at three different levels of knowledge and skills. It does this by purpose-designed GPMS simulation language, which is briefly described in this paper.展开更多
