To optimize the urban public transport network, the paper systematically researches the multifactor analysis and thought about the urban public transport, proposes six binding indexes together with their threshold on the purpose of minimizing the general cost and maximizing the service, and also establishes the quantitative objective functions for the optimization of transport network on the basis...
Establishment of the optimal objective function is the first and a vital step for optimum design. The foundation pit engineering design is a procedure of multi-objective optimization and multi-objective decision. Some of these objectives can be quantitatively calculated, while others cannot. In order to make a comprehensive analysis of the effects of various factors on the optimum design of foundation...
An extended evaluation method for the decision-making problems of alternatives is introsuced by means of extension theory. The extended evaluation method can carry out the decision-making problems of the alternatives based on matter-element models and extended relational degrees. The matter-element model of the desired alternative (ideal alternative) and the matter-element models of alternatives are...
Programming for personnel quota is an important part of Human Resource Management of Enterprise. The configuration of various categories of personnel will have a direct impact on the reasonableness of economic efficiency of enterprises. Generally Programming for Personnel quota was more considered from the point of labor quota. It can basically meet the requirements of the job quantity, but it often...
The goal of this research is to identify the significant factors affecting the firm performance and estimate the system behavior in different operating conditions. By determining the statistical relations of the productivity and effectiveness of the firm with these factors, a decision-making framework can be provided to improve the system performance within the competitive strategy of the whole supply...
According to economic ideas of Gary s. Becker, this paper builds the decision-making model of rural highway scales from the perspective of farmers under funds constraint, and gets the equilibrium condition of rural highways scales. Then with the figure analysis, the paper discusses impact mechanism of the several factors such as the financial structure of rural highway, rural urbanization, rural economic...
Rationally determining the scale of production is one of the key technical problems of the mining from open-pit to underground. In this paper, technical, economic and social factors on the production scale of Daye Iron Mine are considered comprehensively, and the theory and method of fuzzy comprehensive evaluation are used to select. Then, verified by the gray system theory, the optimal scale of production...
The paper makes analysis of the optimal currency composition of international reserves based on Markowitz mean-variance model using Monte Carlo simulation for solution. We calculate US dollar and Euro as the two major reserve currencies for 2007 through 2009, which is also the financial crisis stage. The model suggests to decrease US dollar in late 2007 and to increase US dollar in mid 2008. Our findings...
Most EOL electronic products come from industrial by-products and consumer goods as solid waste. Recycling the EOL electronic products is a complex and long term process. This paper focuses on the location and routing problem of electronic products recycling center. Firstly this paper applies AHP method to select the locations of electronic products recycling centers, and sort various elements by...
Because that transport links are not being considered enough in the existing decision making optimization model of manufacturers' order fulfillment, linear optimization model of manufacturers' order fulfillment is built according to factors as transporter, transport mode, type of line, model, and transportation of goods, transport origin and termination which have combined effects to transportation...
Based on the analysis and description of the problem related to the optimization and integration of the industrial railway sidings, it establishes the evaluation factors set according to the impact factors of the optimization and integration of the industrial railway sidings. It has proposed the decision-making evaluation set which adapts the optimization and integration of the industrial railway...
Lose aversion refers to the psychological phenomenal that losses and disadvantages have greater impact on preferences than gains and advantages. While to a considerable extent, risk aversion as it is commonly observed is caused by loss aversion. This paper integrates Markowitz's efficient frontier theory into lose aversion function, and the portfolio decision of lose averse investors has been discussed...
Fuzzy optimum methods can scientifically define relative importance degrees of sample index. In order to optimize different materials configuration of the C100 high performance concrete, combine with different weight of batch mixture gained through AHP, build evaluation function of high performance concrete configuration process referred to fuzzy optimization theory on the orthogonal test. It makes...
The goal of process design is the construction of a process model that is a priori optimal w.r.t. the goal(s) of the business owning the process. Process design is therefore a major factor in determining the process performance and ultimately the success of a business. Despite this importance, the designed process is often less than optimal. This is due to two major challenges: First, since the design...
Recently, wireless sensor networks are used in an expanded bulk of utilizations. In this research, a lighting control system is proposed on basis of wireless sensor networks named LACS (Lighting Automatic Control System). This system with the ability of explaining the users' activities, in addition to providing the needed lighting which provides the satisfaction of users, will provide energy saving...
When emergency occurs, a reasonable and efficient resource scheduling system is urgently needed to deal with influences caused by emergency. In regard to the scheduling problem of single one-time consumption resources in the emergency logistics system, this paper establishes a resource response decision model with the goal of minimum emergency response time, least saving points, highest reliability...
This paper focuses on the hybrid multiple attribute decision making problem with weight information unknown and defines some new operations of 2-tuple linguistic firstly. Then, an optimization approach based on maximizing deviation theory is proposed to determine the weights of the attributes which they can be used to aggregate the estimated values of different attributes into a collective 2-tuple...
From the avoiding collision angle of multi-ships encounter, this paper applies target decomposition- coordination method of large-scale systems theory to decompose the anti-collision turning into multiple independent sub-problems of optimization between the ship and multi-ships, and by use of coordinator we can calculate this ship's optimal turning angle to avoid collision. The simulation result shows...
In this paper, we analyze performance of cooperative spectrum sensing under counting rules when exponential model involving the spectrum usage (SU) is utilized to characterize the burst nature of primary user (PU) link. Considering both the reliability and the efficiency performance of sensing, we use the average error probability (AEP) in final decision making as metric. We derive a closed-form expression...
This paper firstly defined what tacit knowledge is and analyzes its network characters in an organization. Then, taking a small high-tech enterprise as a case, we constructed its tacit knowledge transfer network with methods of SNA by using software Ucinet6.237 and Pajek2.0, and make quantitative research of the whole network, individual networks and clique analysis. Finally we put forward some optimization...
