Abstract: The research of this paper is based on the domestic airline operational control that exist variety of factors under the state of emergency, such as emergent meteorological conditions, flight flow and alternate airport security conditions, the potential human factors and organizational management operation, in order to establish the correct hierarchy model, we analyzing the inherent correlation of these explicit and implicit factors which impact on the dispatch release work, then apply these factors to the Bayesian network structure and use Gaussian normal distribution to solve mean value and mean square error to determine the weight for influence factors so that run a aviation safety assessment for dispatch operation, it can help the company to propose targeted security operating strategy.

Abstract: This paper focuses on the human resource allocation problems in multi-projects.The model of multi-project human resource allocation was established.Dynamic programming and matching game theory was adapted,a real-time dynamic game algorithm was proposed.the algorithm has adapted multidimensional state variable input method.In the stage 0, input A1, A2, A3,…,An and get the optimal variables’et by the filtration of the optimal function set.These variables enter the stage 1 by the help of the state transition function.Under the limit of B, these variables are filtrated by the optimal function to get the optimal strategies.As variables, these strategies enter the stage 2, and so on.Finally,the optimal scheme of the resource allocation between each other has been formed.Through the practical example test,the model and algorithm was found feasible and valid.

Abstract: This paper focused on selecting and developing the optimal new products in the environment of complex constraints. Selection models of new products development plans in the complex environmental constraints have been established. The models were designed by designing five variables, defining the four basic model’s initialization and analyzing variable structures of models. Based on the model and the actual problems, the optimal selection algorithm models of new product development’s plan in the complex environmental constraints have been designed. First of all, new product’s evaluation was evaluated by using the environmental factors to calculate the weight of related factors in this environment. Secondly, the data’s table of algorithm and the iterative process were designed. Finally, the optimal new product by iterative algorithm was employed to prove the optimal solution of in the algorithm. The model and algorithm in the specific implementation process has good flexibility, high efficiency and optimality.

Abstract: Spare inventory optimization is one of the important problems for a maintenance facility to repair equipment in a high efficiency and low cost manner. In this paper, a model is developed to solve the problem of spare parts decision for complex system maintenance with mixed multi-echelon spare inventory. Spare parts are categorized into three types in terms of number of inventory echelon. Spare support availability and costs are analyzed respectively for each type.

Abstract: Location of logistics distribution center is affected by many factors, so choosing an appropriate method to evaluate is extremely important. Location problem of logistics distribution center by using the method of AHP and grey theory is analyzed and evaluated, and the corresponding model is put forward. Finally, the examples show that the model can effectively deal with the location problem of logistics distribution center.

Abstract: In the study of complicatedly mechanical system, the conventional model of single reliable grow is only used to study time function relation of lapse moment and system reliable grow .In order to study the affect of different lapse modes and mend measures to reliable grow of system, the model of mix reliable grow is proposed with the maximal forecast time of complicatedly mechanical system. The project background and learn algorithm of model is in detail discussed, the mimic example of reliable model of the maximal forecast time of complicatedly mechanical system is showed.

Abstract: With the development of modern logistics system, the automatic logistics distribution centers have been built in most tobacco enterprises. The packaging system plays important role in the distribution center, it is necessary to construct a set of scientific method to evaluate the packaging system mode. According to the real situation of tobacco logistics distribution center, the cost and benefit are set to the general goal. For these three modes of packaging system, packaging by hand, automatic packaging and packaging by heat-shrinkable material, the evaluation index system and hierarchical structure are built. Refer to the hierarchical chart and the principle of AHP, the weight of each index is calculated. On the basis of weight that worked out by AHP, the final evaluation result can be found and analyzed follow the principle of fuzzy comprehensive evaluation. Finally, reference the consequences of the FCE, the DEA model based on FCE is used to enhance the integrality and systematic of the evaluate result.

Abstract: With increasing awareness of environmental protection, electric vehicle becomes more and more important in daily life. The electric vehicle sales forecast can occupy a favorable position in the unpredictably market. The grey theory is mainly applied to single exponential growth of data sequence, as well as the linear regression model needs to collect a large quantity of data. For these problems, this paper puts forward the grey linear regression model to predict the electric vehicle sales and result is calculated by using Matlab programming. Matlab is software which can carry out numerical calculation. The feasibility of this combination model is verified through the example. It can obtain higher prediction accuracy by collecting relative little data. The combination model has a lot of advantages in the electric vehicle sales prediction.

Abstract: When the device is inspected only once, there are only two possible statuses either functioning or failed at the time of inspection. In this paper, we consider a series system consisting of two components with lifetimes following weibull distributions and a competing risks model is used to study the series system for quantal-response data. Based on the quantal-response data, the maximum likelihood estimates of parameters of weibull distribution are derived. The model is illustrated using a practical numerical example of two-component series products, and the statistical properties of the maximum likelihood estimators were studied via Monte Carlo simulation under three-stage inspected scheme for various sampling sizes. This study verified that the model is practical. This research results can be applied to the reliability analysis of one-shot products with Weibull components lifetime distribution and the stockpile storage performance test.

Abstract: We encountered many obstacles in the implementation process of Activity-based Costing. But the new accounting standards fully embody a new accounting concept, coinciding with the concept of Activity-based Costing, and it brings a new opportunity to implement Activity-based Costing. The paper discusses the content.
