In order to achieve effective cooperation of the engineering project team, this paper constructed the cooperation model of the engineering project team and analyzed the cultural regulating, profit regulating and institution regulating in the engineering project team form the viewing angle of system theory based on existing research results. Furthermore, this paper proposed four kinds of management...
We research conducted the strategic purchase model of the the home appliances enterprises based on revenue-sharing contract in this paper. Under such a contract, a manufacturer pays a supplier a wholesale price for each unit purchased, plus a percentage of the revenue generated by manufacturer that is determined by manufacturer's purchase quantity and price. Finally, a numerical instance is used to...
Considering the impact of the objective environment on the economic system, this article introduces gray elements to a dynamic input-output model which is based on variable structure control, and proposes the methods of determining the important parameters of the model. This model can reveal the relationship between propensity to consume, propensity to invest, the structure of consumption and investment,...
Quick and accurate response to the relief demand is vital to an emergency logistics network under disaster spreading. In this paper, we first characterize the disaster spreading process to forecast the time-varying relief demand, by using an epidemic model to analyze the relationships among three groups of affected individuals. Then, a new three-tiered emergency logistics network equilibrium model...
Aiming at the reverse bullwhip effect in reverse supply chain (RSC), a non-cooperative stackelberg model is set up with agreed collection volume. The centralized, decentralized and coordinated systems are brought out successively and the operation mechanism is analyzed afterwards. With the developed expense-sharing contract as the object of the study, the fact is proved that the RSC with collection...
Demand forecast of emergency material is the precondition and foundation of planning emergency material storage strategy. Because of the emergency logistics have the characteristic as follows: sudden, uncertainty, non-conventional, the weak economy, complexity and so on, On the basis of defining the fuzzy condition and fuzzy transfer probability, the paper divides the emergency material demand into...
The problem of the layout of NEMLCs (National Economic Mobilization Logistics Centers) is one of the most important long-term decision-making issues. The result of NEMLCs's layout directly impacts many aspects of mobilization, such as time, reliability, quality, efficiency, cost, and so on, consequently affects the effect of the mobilization. Under the restriction of mobilization time, the paper establishes...
With deepply research thunderbolt's critical materials safeguard working rule, the paper has analyzed our country critical materials reserve present situation, proposed based on the AHP critical materials taxonomic approach. In view of the critical materials safeguard's characteristic, has constructed the cross time critical materials inventory control model and the critical materials information...
Against the issue about revenue maximization of cycle project product, apply ideas of game balance, base on a single product manufacturers and retailers in closed-loop system, study when recycling waste products, decentralized decision-making model and a joint pricing strategies of enterprises; In considering the environmental costs of products, proposed differential pricing policy model in product...
In this paper, analyzing Hebei University of Engineering Stadium project, judging the qualification of the tenders by using AHP based on the thoroughly analyzing of the indicators of the index system, establishing the evaluation model, testified the efficiency and science of the model, summarizing the prerequisite of the reasonable lowest bid, formulating the reasonable lowest bid of bid in construction...
Implant-abutment connection plays an important role in the long-term success of dental implant. It should be able to resist bacterial leakage. Colonization of bacterial in microgaps along implant-abutment interfaces will lead to inflammatory reaction. One of the factor which have been identified to produce microgaps is micromotion. This study was conducted to analyse micromotion and stress distribution...
Among factors to contribute for the primary implant stability are implant design parameters as well as implant body surface condition. Through this study, the stress distribution within bone around implant will be investigated under variation of implant lengths and surface conditions by using three dimensional finite element analysis. Six finite element models involving three different zygomatic implant...
By applying the theories of the PSR and coupling the PSR model with the green marketing competence, this paper puts forward three models for the green marketing competence promotion: PSR filter green promotion model of government macro-dominance, PSR integration practice green model of production system elements, PSR green-driven model of 4P strategy combinations. And it draws the conclusion that...
By using of the symbiotic theory in population ecology, this article describes three symbiosis patterns between logistics enterprises in logistics park, parasitism, commensalism and mutualism. And then it analyzed the economic benefits of symbiotic logistics enterprises in the park by using the logistic model of ecology.
In this paper, we consider a manufacturer-supplier chain situation in which the manufacturer coordinates, e.g., supports, its supplier's innovation that can eventually lead to supply cost reduction. Developing some mathematical models, we show that sharing innovation cost has a better coordination effect, and manufacturer can share a part of innovation cost when the innovation coefficient is lager,...
Data Mining can find out the hidden important information in mass data, whose main purpose is to help decision-makers to look for the potential relevance between the data, to find out neglected elements, and make decision based on these models automatically. This paper, based on the discussion of data mining, analyzes the framework of enterprise decision support system, designs the enterprise decision...
As a new developing economy in the 21st century, there have always been concerns about the scientific evaluation of a recycling economy. Based on the principle of material flow analysis and resource value accounting models in enterprise(s), through defining and tracking the value information of resource inputs, consumption, output and disposal in the production process, this paper builds a new evaluation...
This paper makes a detailed analysis of purchasing management, pointing out the existing problems and optimizing the process, to improve the quality and reduce the cost of purchasing. Inventory management is also studied by elaborating the quantitative ordering method and its application in engineering; analyze the inventory cost control of construction enterprises with respect to supplier and inventory...
Viscoelasticity is an inherent property of the soft biological tissue and is increasingly used as a diagnostic parameter, e.g. in characterizing liver fibrosis and breast tumors or tissue-mimicking phantoms preparation. MR elastography (MRE) enables the noninvasive determination of the viscoelastic behavior of human internal organs. In this study, multifrequency magnetic resonance elastography was...
As a key unrenewable energy, coal plays an importantly strategic role in national economy. With the increasing of the depth of coal mining, there is more difficulty in mine construction. Risk management has become more and more important to mine construction project. the paper uses entropy and unascertained measure model and risk matrix to assess the risk of mine shaft construction project. It is...
