Purchase contract management is an important links of purchasing and supply chain management. This paper discusses two functions of purchasing contract, i.e. management and coordination. Managerial function is through contract to control the operations of the parties to keep the supply chain stable. Coordination function is through risk sharing and benefit allocating mechanism to improve and optimize...

Yingkou City is the fastest growing region in recent years, and great potential for future development in Liaoning Province. Through analysis of the opportunities, threats, strengths and the weaknesses in the industry development in Yingkou, we should utilize...
in this paper, the association rule in Data Mining was applied to the in-warehouse assorted pallet in the three-dimensional warehouse. The extraction of the association rules between materials and the realization of the in-warehouse assorted pallet strategy are discussed in detail. The experimental result shows: This method can reduce the job number of times.
Finite Element Method (FEM) model was built and model analysis was executed for a thin-wall cylinder dynamometer with ANSYS, the natural frequencies and modal shapes of the dynamometer are obtained. The topological optimization was done with the variable-density method. The utilization rate of materials was improved, and the lower model frequencies were increased.
To extract polysaccharide of Camellia Cake, cellulase-assist method was used. The extraction conditions were: temperature 50°C; time 3h; adding amount of cellulase 0.35%. The extract rate of camellia cakes polysaccharide is 26.62%, The adequacy of this model was confirmed.
Safety for the occupants of medium-heavy truck is a prime consideration for cab structure design. Among front, rear impact and rollover accident, it is rollover that results in severe Casualty for occupants. Especially during the whole process of 180° rollover accidents,including two steps,the first step is 90° rollover, the second step is 90° rollover up to 180°. A new more legal and strict rollover...
In this paper, the topology optimization design of two-material micro compliant mechanism that allows for treating local stress constraint is investigated. A mathematical model is constructed in which the mechanical advantage of the mechanism is posed as objective function while displacement constraint, material constraint and stress constraint are considered simultaneously. The element free Galerkin...
Provide the minimum desired-short-supply mode for the equipment material for preparedness in the all second reserve stock-station on the restrain condition of limited fee. Through identify the quantity from the rear area warehouse to the stock-station, we get the optimization allot plan. Finally we give the sample and diverging configuration mode.
Friction Stir Welding (FSW) is a relatively new solid-state joining technique, which is versatile, environment friendly, and energy and time efficient. For a comprehensive understanding of the effects of process conditions, such as tool rotation speed and traverse speed, on characterisations of welded materials, it is essential to establish prediction models for different aspects of the materials'...
To study the application of rectangular ranging, this paper proposes the ant algorithm based upon the lowest contour, which makes full use of the information on rectangular and seeks for the best sequence by the ant algorithm on the basis of the lowest contour algorithm. The experiment data demonstrate that this method facilitates to find optimization in a rapid and efficient manner, and the results...
In this paper we study the path choice problem of material transportation in emergency based on the analysis of fuzzy concept. The effect of fuzzy factors on road is mainly considered to obtain an optimal calculation of path choice. A routing model with random probability for emergency rescue center is proposed with utilization of the theory of uncertain programming with fuzzy probability. The uncertain...
The task of finding crucial design interdependencies in the form of mathematical relationships (empirical or otherwise) in an engineering design problem using the Pareto-optimal front is referred to as innovization. Past studies on the subject have limited themselves to a single front. In this paper we introduce the higher-level innovization task through an application of a manufacturing process simulation...
With the growing concern about requirements of information literacy in the modern society, the needs and applications about the information resources are stronger and stronger in the Information Literacy Education. Educational audio-visual resources have a unique educational function as a dynamic resource, a way of information expression and creating, a means of information exchange and cooperation...
Synthesis of n-butyl lactate catalyzed by carbon nanotube pured liquid oxide was studied. The influence of the amount of catalyst, catalytic reaction time and temperature on the conversion rate of lactic acid was discussed. The synthesis conditions of n-butyl lactate are as follows: the ratio alcohol to acid is 2∶1, the amount of catalyst is 0.5 g/0.1mol lactic acid, the reaction time is 2.0 h and...
[Objective] The research aimed to optimize extraction process of total flavonoids from Pteridum aquilinum var.latiusculum and provide a theoretical basis for development and utilization of total flavonoids from Pteridum aquilinum var.latiusculum. [Method] Taking the yield of total flavonoids as index, the orthogonal test L16 (44) with four factors and four levels was used to optimize the technological...
With the rapid global integration of economic progress, group corporations such as capital as the link through the common wealth's economy continue to optimize the financial management processes and accelerate the management of change, in order to enhance the management performance, thereby enhancing the competitive strength. In this article, we focus on the financial management system's construction...
The mining face in the Twelve Mine belong to Pingdingshan Colliery Group Co. LTD is immerged in the depth of 1015m between 1130m. Extraction Scheme of Protective Seams was used as the key technology. So the law of mine pressure in the tunnel below should be further researched. To the actual actual conditions, the three-dimensional model was build using the FLAC3D. The mine pressure in the tunnel below...
Response surface methodology(RSM) was used for optimizing ultrasound-assisted extraction of malania polysaccharides. Based on single-factor experiments, three independent variables, namely extraction time(A), ultrasonic temperature(B), and material/water ratio(C), were selected as casual factors. The experiments were arranged according to Box-Behnken central composite experiment design. Response surface...
This experiment was an attempt on extract polysaccharide from Argopectens irradias using water and ethanol and assay its contents using sulfuric acid and phenol method. The extraction rate of crude polysaccharide from Argopectens irradias was found to be 5.419 % and its content was 16.13%. The average recovery rate of crude polysaccharide was 100.7% with 1.72% RSD. The results showed that the method...
Evaluation and selection of green sustainable development (GSD) strategies is a critical but difficult process involving many uncertain factors and affected by dynamic conditions. The decision problem is essentially multi-objective. This research proposed a simulation based method that uses simulation to capture the complicated process flow and decision logic involved, and interface the simulation...
