Mobile devices have become more and more powerful with lots of embedded sensors providing sensibility of various data, which makes crowd sensing a compelling paradigm followed by emerging applications. In this paper, we design a crowd based incentive mechanism to stimulate participants joining sensing campaigns with consideration of location privacy. In our incentive, MagiCrowd, we creatively cluster...
This research examines optimal operation of microgrid systems. Microgrids are disaggregated from main transmission grid. Microgrids are able to integrate distributed renewable energy, take advantage of waste heat, provide higher power reliability, reduce electricity transmission loss, and decrease greenhouse gas emissions. The study considers solar power, wind power, biomass power, gas turbine, fuel...
Agricultural industry chains are increasingly vulnerable to natural disaster such as earthquakes or hurricanes. This paper investigates the ripple effect on the agricultural industry chain which is heavily influenced by the natural disaster. Taking the pig industry chain in the disaster area -Luzhou, Sichuan Province as an illustration, the paper was committed to the dynamics of price adjustment and...
Although competitive games have multi-fold benefits to students' learning, such as motivation, satisfaction, and effectiveness, inappropriate competitive learning activities may have some negative impacts on students. From the literature, the authors have identified three main strategies which may reduce the negative impacts in competition game. However, because these strategies target only at the...
The idle speed control is one of the most generic and basic automotive control problems. In this paper, the engine idle speed control problem comes down to optimization problem with input and state constraints. The controller based the quasi-infinite horizon nonlinear model predictive control (NMPC) methodology is designed to regulate the engine speed as close as possible to a reference value. The...
According to the basic theory of the service quality and the characteristics of highway traffic construction, this paper pointed out the conception of trunk highway service quality. Based on the theory of user satisfaction degree, the attributes were selected aim to establish comprehensive evaluation system of trunk highway service quality. At last, an example was analyzed to verify the reasonableness...
The agent-based simulation is introduced in this paper in view of the complexity of industrial cluster system. The micro-mechanism of enterprises knowledge overflow in industrial cluster is analyzed, and then the enterprises knowledge overflow is simulated based on agent. According to the simulation, the positive and negative effects of enterprises knowledge overflow in industrial cluster are analyzed.
With aggravating of market competition, the operation of supply chain coordination becomes more and more important. Therefore this paper firstly describes the capability and profit of supply chain members and the operation of supply chain coordination using multiple-objective programming and proposes a multi-product, multi-stage supply chain coordination model based on VMI ,which comprises one manufacturer...
State estimation plays the key role in real-time bulk power system reliability operation and economical market operation. Active transactions across the regional transmission systems are integrated nature of today's electricity markets. To ensure stable and adequate SE solution, EMS engineers are paying more attentions on external network models, which usually deal with real-time operation uncertainties...
Electricity markets are designed and operated based on physical constraints of modern power systems. This panel will review the practices on post-contingency congestion mitigation with market forces, from the perspectives of market design and market operation. Future challenges will be also discussed.
Differing from some past studies methods, this paper studies the question of price competition from the angle of the starting point of contesting market shares of the manufacturers between two color TV supply chains under the Stackelberg game model. By the study we succeed in getting the prerequisite of the price reduction and its equilibrium result of price competition of the two color TV manufactures...
In many countries, small and medium-sized enterprises (SMEs) are the principal generators of new jobs and economic activity. If guarantee funds are to be effective, a majority of firms can obtain financial assistance through corporate bonds market. This paper describes the mutual guarantee bond which can be a viable solution to the problem of access to credit from capital market for small and middle-entrepreneurs...
The Cellular Automaton model is applied to study the technology diffusion in industrial clusters. A cellular automaton model for technology diffusion in industrial clusters is formulated through equipping "the ability of memory" to cells and considering various influent factors in industrial clusters. Based on this model, the simulation experiments are carried on to find out the relative...
Fuel cell electric vehicle has very good application foreground for it has some advantages, such as high efficiency and little emission, etc. In order to characterize the structure of hybrid power system for fuel cell electric vehicle, the project of parallel hybrid power system was brought forward, which consisted of fuel cell, NIH battery and DC/DC converter. The power flow of hybrid power system...
The development of global economy makes the mass customization production become popular. Some of manufactures which originally used the conveyor assembly line begin to use a kind of new production system which is called cellular manufacturing system. The results prove that cellular manufacturing system is better than the assembly line under some environments. This purpose of this paper is to compare...
Ensuring power system reliability is among the top responsibilities of an RTO/ISO. Focusing on operating reliability, this panel will review the PJM's practices on reliability related risk management from the power system operations and market operations viewpoints, recognizing the interrelationship between system and market operations. On one hand, system study, outage coordination and reliability...
