In order to promote knowledge sharing and knowledge reuse of scientific research achievements, this paper proposes a knowledge network model which acts as a direct access to the knowledge existed in the achievements. As knowledge network can be treated with a kind of complex networks, this paper then optimizes the primitive knowledge network model by analyzing its network characteristics. Figures...
Assembly sequence planning plays an important role in the product development process. It is an important factor that determines quality and cost of the product assembly. Cost in assembly can be reduced by the implementation of generating automatic product assembly sequences, and selecting the optimum sequence in product assembly process. Assembly sequence planning (ASP) is combinatorial problem....
Using the thought of the value -chain to represent the valuable activities of information management, also importing the concept of the important contribution of the knowledge activity , thus lays the foundation on the theory for the performance prism to evaluate information management, pointing out the framework of the performance prism. Point out the concrete indices of every panel. Calculate the...
There are some problems in China's technical innovation activities. Such as the elements can not flow smoothly among the subjects of technical innovation activities, the objectives of technological innovation activities are not consistent and the efficiency of transformation and utilization is low. Building a target system of the cycle in a technological innovation chain is proposed in this paper...
Supplier management is an important problem with strategic meaning in the automotive supply chain of China. However, the complexity of the auto product makes difficulty of the supplier management in the auto industry. From the view of cooperation and collaboration, the essence of the supplier management is analyzed and the concept of supplier service optimization is proposed in this paper. Also, the...
After analysis of the data from Dalian bus IC card database, the paper propose an optimization algorithm for bus scheduling. By introducing an artificial immune algorithm based on information entropy, the optimal or the quasi-optimal solution to this multi-variable and non-linear problem of bus scheduling can be found efficiently. The experiment results demonstrate that the optimal bus departure intervals...
The vehicle routing problem (VRP) is an important problem occurring in many distribution systems, which is also defined as a family of different versions such as the capacitated vehicle routing problem (CVRP) and the vehicle routing problem with time windows (VRPTW). The ant colony optimization (ACO) is a metaheuristic for combinatorial optimization problems, and the max-min ant system (MMAS) is a...
In this paper, we study the newsvendor model with profit re-distribution. It is different from classical model that sale process is distinguished normal sale and promotion stages. Vendor can select to sales promotion for increasing their return when real demand is lacking. We get two mathematical expressions of traditional optimization order quantity q* and new optimization market size N*. At the...
This paper proposes a new supernetwork model of a three-tier supply chain which consists of manufacturers, retailers, and ultimate consumers. In this model, the manufacturers who produce a homogeneous product can sell product not only to retailers but also directly to consumers by Internet, and only the retailers can return the unmarketable products to the manufacturers. The model gets equilibrium...
This paper proposed an improved ant algorithm with feedback function extension and dynamic pheromone design (dynamicAnt) for the network traffic management issue. The scheme first mapped the network traffic path delay and bandwidth metrics into the parameters of the basic ant algorithm. And then extended the network feedback function to the basic ant algorithm by simulated it as the food smell. By...
Evolutionary particle swarm algorithm is proposed for blindly identifying the communication channels. The channel coefficients vector candidates are evaluated by scoring positions of a swarm of particles flying through the multimodal problem space based on their values of the higher order cumulant cost function. The flying is constituted by the interaction of these particles and the alteration arrangement...
In order to tackle the shortage of existing research on coalition formation, where one agent only can take part in a coalition, this paper introduces overlapping coalition, and presents a novel way to settle the problem of overlapping coalition formation with Subagent. Then a particle swarm algorithm with dynamic weight value based on the similarity calculation is applied to solve overlapping coalition...
This paper makes researches on optimization of the curriculum scheme and teaching procedures in AIS. The main characteristics of it are: (1) optimizing the internal structure of curriculum scheme based on traditional classification, such as offerring "basics of industrial technology" and "computer basics" in elementary courses, setting up "accounting theory topic " in...
On the basis of the enactment data and information in workout plan, there are some traditional time-cost tradeoff methods, which optimize time-cost in the practice projects. It is difficult for these methods to achieve anticipate purpose as a result of the changes of construction conditions. Aiming to the above shortage, on the basis of discussion relative between time and cost, some problems of relative...
End-to-end resource planning (EERP) is an attention field of software engineering in recent years. But the question most persons concern with is how to connect different of value activities, by which could bring profits with enterprises. After analyzing the production value chains and service requirements of power enterprise, it attempts to design and accomplish the end-to-end resource planning by...
Integrated circuits generally involve many layers of metallization as semiconductor devices require different functions; otherwise, the devices' density increases. The inter-metal dielectric (IMD) is deposited between metal layers to provide isolated capability to the device and separate the different metal layers, which are not necessary in conducting electricity. A good isolated capability will...
A portfolio optimization with downside risk based on benchmark is investigated. The expected relative terminal wealth is maximized under a new risk constraint, RVaR, which is defined by a relative wealth process. In a Black-Scholes setting, stochastic analysis method and nonlinear programming theory are used to obtain explicit solutions of the optimal strategies, which include the riskless asset,...
In metal cutting, optimal cutting parameters are greatly preferred to achieve the trade-off between cost, efficiency and quality. The cutting parameters for both rough machining and finishing of titanium alloy were optimized with fuzzy comprehensive evaluation. The orthogonal experiments were designed with four factors at four levels. A multiple objective model considered for material remove rate,...
The purpose of this paper is to use the Analytic Hierarchy Process to build up a model on identifying the strategic risk. The new model is based on Baird and Thomas' Contingency model which is in accord with the strategic management of the traditional mode of thinking. At the same time, on the basis of systematology we use the multi-objective fuzzy optimization theory as strategic risk measurement...
In order to effectively deal with randomness and fuzziness in multi-objective optimization, according to the advantages of cloud model in dealing with the two phenomenon, it is combined to multi-objective optimization problem. In addition, for genetic algorithm, because of the inherent of parallel mechanism, it can ensure to obtain numbers of possible Pareto optimal solution at the same time, and...
