Aiming at the stock problems faced by brand traders such as out-of-stock and overstock, this thesis has analyzed what leads to the stock problems of fashionable products and puts forward a demand forecast model of three stages with the help of an operation model of fashionable products' supply chain. A stock control model and an inspiring formula that fits those brand traders' fashionable products...
We study the problem of jointly determining the promotion optimizing and inventory control of multiple beer product variants in a Chinese retail supermarket based on demand forecasting. We examine the joint effect of two modes of promotional policies: price discount and inventory stimulation. Under the demand with the price sensitivity, inventory sensitivity and randomness, we formulate a more practical...
This paper introduces the concept of cluster supply chain. Cluster supply chain is a set of networks comprised of horizontal ties between firms within a particular industrial cluster, which are sequentially arranged based on vertical ties between firms in different layers. Cluster supply chain analysis integrates supply chain and network perspectives on inter-organizational collaboration with particular...
To cope with the challenges of traditional quality management system applied in supply chain, which consists of internal practices that are contained within a firm, external practices that cross organizational boundaries integrating a firm with its customers and suppliers, a collaborative quality management system model into supply chain, and corresponding functional modules and framework were all...
The supply disruption has more influences on the enterprise performance than the demand disruption, while closer cooperation with suppliers is extremely important to mitigate supply disruption risk and improve performance. After the global supply chain emergencies arising frequently, all companies should ensure that supply disruption management becomes an intrinsic part of decision-making, to deal...
This paper deals with an improved design scheme for an amphibious robot inspired by various amphibian principles in animal kingdom. Considering the propulsive features of existing amphibian modes synthetically, a novel hybrid propulsive mechanism that integrates fish-like swimming with wheel-paddle-fin movements is proposed. The robot is able to implement speedy and efficient fish-like or dolphin-like...
In order to explore the moon more effectively, it is very important to enhance the ability of navigation and localization of the lunar rover for exploration achievement of scientific goals. In this paper, an Accurate Localization in Combination with Wireless Sensor Networks and Laser localization scheme is proposed. First, the lunar rover position system consisted of the Lander, the lunar rover and...
This paper deals with the fuel optimal control for the powered descending phase of a lunar module. Firstly, in the target coordinate frame, a 3-dimensional precise kinetic model is formulated. Secondly, the fuel optimal control problem for the powered descending phase is transformed into a standard constrained optimal control problem. By using a computational method and a time scaling transform technique,...
According to the terrain features of the irregular environment, we propose a novel mobile mechanism of the transformable wheel-track robot (TWTR). The TWTR can adapt autonomously to the irregular environment by transforming the track configuration or by changing the locomotion mode between track mode and wheel mode. The TWTR mechanism consists of a control system unit and two symmetric transformable...
Considering the redundant degree of freedom (DoF) of open loop kinematic chain, the closed-loop inverse kinematics algorithm (CLIK) via pseudoinverse method is used to solve the corresponding joint trajectories if the end-effector trajectory is given and the constraints of joint limits are applied to modify the null space in order for some optimized solutions. The repetitive trajectories are tracked...
To study the calculating method of the total efficiency of the innovative multi-range hydro-mechanical continuously variable transmission (HMCVT) when factors such as the power cycle and the variation of the efficiency of hydraulic units with their input power are considered, this paper established an approximate efficiency formula of hydraulic units according to test data, given an efficiency algorithm...
In buildings, a serious waste of energy exists in HVAC, and refrigeration stations account for the most of energy consumption. Because the coupling exists between devices of refrigeration stations, the traditional evaluating indicator based on independent device can not reflect the energy consumption characteristics and the optimal energy consumption of refrigeration stations toward different load...
A novel permanent magnet motor actuator on high voltage circuit breaker is proposed. Based on the characteristics requirement of the circuit breaker, a limited angle permanent magnet brushless DC servo motor actuator is designed. By using the finite element method, the basic characteristics and dynamic simulation of starting are carried out, which the simulation results of the motor (such as electromagnetic...
This paper presents a multi-dimensional fuzzy interpolation neural network (FINN) which extends fuzzy interpolation that was developed to approximate single input single output functions to multi-dimensional space. The multidimensional fuzzy interpolation piecewise approximates multiple-input-single-output functions with small hyper-surfaces defined over fuzzy regions. The vertices of these fuzzy...
A ballroom dance is a performance between a male dancer and a female dancer and consists of its own steps. The dance is led by a male dancer and a female dancer continues to dance by estimating the following step through physical interaction between them. A dance partner robot, PBDR, has been proposed as a research platform for human-robot coordination. It dances a waltz with a male dancer by estimating...
This paper proposes a novel fingerprint matching algorithm. The matching process was divided into three stages. In first stage, local orientation structures matching was performed to evaluate the similarity of orientation information around the minutiae. In the second stage, local minutia structure matching was performed to evaluate the similarity of neighborhood minutiae distribution around the minutiae...
An emotion based spatial design technology can change some factors with which a user may affect emotion, and enable a user to design a desired space. In composing an actual space, the production period may be reduced and the quality of produced contents may also be ensured. An emotion based digital spatial design can either help a user design an emotional space by utilizing a basically constituted...
A multi-camera system is widely used for determining the poses of large objects in practice. This paper thus makes contributions to applying multi-camera systems with high accuracy and efficiency to industries, such as automotive and logistics. Some valuable approaches - pattern weight, zero measurement, pattern compensation and camera pose on-line recalibration, to solve the practical issues are...
Mixel decomposition of remote sensing images is one of valid assistance means for improving quality of feature extraction from the images. Some problems exist in normal linear mixels decomposition, for example, registration error is too large, and neighbourhood information can be took full advantage of and so on. These result in that distortion of new images generated after linear mixels decomposition...
This paper proposes a novel quick method to locate a person's eyes in an infrared image. First, we use the homomorphic filter to enhance the contrast of image, segment the human face through iterative threshold choosing algorithm and integral projection function. With the eyes and face geometry knowledge, we get the eyes region roughly. Second, we use the RAMF(Ranked-order Adaptive Median Filtering)...
