Abstract Implementing an ERP system has become the primary consideration for many enterprises during processing E-commerce. It has also become the data platform of information foundation construction in many enterprises. Among these implementation cases, however, some are facing failures due to the following reasons: the organization business flow is unable to make changes coordinately, the consultant companies lack of experience, or the user sites are being resisted while implementing an ERP system. All the mentioned reasons have caused their ERP project delay by deadline. This, therefore, results in the huge increase of the cost and even an abnormal operation system during the implementation. Eventually the enterprises would have to make an announcement to fail. The management and control of implementing an ERP system decides the success of the system. The subject of this study is to probe into the process of implementing an ERP system. Beginning with the sort-out of Chinese and foreign documents to find out the key success factors during the process of implementing an ERP system and then collecting the realistic data from the software company¡¦s viewpoints to understand the concrete methods of key success factors. The software consultant company, therefore, plays an important role during the process of implementing an ERP system. We, hereto, generalize the viewpoints of high-level administrators, the project manager, the senior consultants and the technicians about the key success factors during the process of implementing an ERP system from the software consultant company¡¦s angle. After that, the practical perspectives of the software consultant company are being discussed and analyzed to verify if there is any difference with the results which were generalized from probing the documents. Results of this study have shown that the most important key success factors are ' the commitment and support of high-level administrators ', ' the integration degree of other systems' and ' the procedure innovation'. The secondary key factors are ' the production operation characteristic 'and ' the interdepartmental characteristic '. The key factor that is not important is ¡¥the methods of systems implement¡¦. In spite of the existing large number of researches about ERP, the ones discussed from the software consultant company¡¦s point of views are quite few. This study probes into from software consultant company¡¦s viewpoints and to collect related key success factors while hoping to be a reference for other consultant companies and relevant units in implementing ERP system.

Then there is described active and passive stress state of the silo and their influence on filling and emptying. The thesis deals the possibility of the formation of buckling vault (bridging) during emptying and ways to solve it. There are also described various possibilities of modifications and equipment of the silo in relation to the type of material.
