The new generation of R&D personnel has unique personality characteristics and work values, which brings challenge for the human resource management in enterprises. Based on the literature analysis and in-depth interviews, this paper puts forward a five-dimension model of work values for the new generation of R&D personnel and makes an empirical test through the questionnaire survey and statistical...
Building on our previous work, we examine the effect of role specialisation on a society using a scenario from the area of comparative economics. In connection with this our central contribution is the use of Interval Type-2 Fuzzy Sets to model emerging normative understanding, which is represented using the concept of Dynamic Deon tics. This integrated mechanism, along with a supporting visualisation...
Currently universities have faced a popular realistic subject, that is, how to construct a reasonable salary incentive mechanism based on two tasks of teaching and scientific research for teachers. This paper builds a multi-task principal-agent model based on those tasks which are delegated to teachers by universities. Then, through in-depth analysis of the model, we explore the relationships among...
The research on the business models is a hot topic in recent years. It is an interesting problem to study the business model of the service. There are three kinds of models related: classical service models, Business process (BP) models and the enterprise business (EB) models in management. However, none of them covers all the properties of the service business model. In this paper, we define the...
With the increasingly serious situation of global warming, governments all over the world have adopted various carbon emission policies to strengthen the carbon regulation to enterprises and supply chains. This paper builds a supply chain (two-echelon supply chain, one producer and one retailer) carbon emissions model based on the theory of System Dynamics. We introduce the carbon emission polices...
Gift cards are widely used by many enterprises nowadays for products promotion. Gift cards are used not only for a basket of goods, but also for some specific kinds of goods. In this paper, we characterize consumers' purchasing behavior according to descending consumers' reservation price, then develop a model to derive the optimal purchase amount threshold and gift card value. We find that offering...
We extend the expectation-based loss-averse newsvendor model according [1] by assuming that decision maker confronts deterministic demand and uncertain supply at the beginning of a selling season. We show with numerical study that the higher the penalty coefficient, the lower the optimal order quantity. Higher retail price and salvage value lead to optimally order more. However, when the wholesale...
This paper builds a simple model to analyze advertisement on a digital map. In our model consumers search for a specific firm but might be lured to nearby firms. A map owner charges a lump sum fee and controls entry. We show that the map owner has incentive to manipulate the quality of firms on the map according to the level of consumers' switching propensity and advertisement aversion. Strong switching...
Over the last fifteen years, computational intelligence applications have proliferated solutions to financial engineering problems, bringing a new fertile area of collaboration between professional engineering and financial communities. Computational systems based on machine learning techniques have become indispensable in virtually all financial applications, from portfolio selection to proprietary...
This paper proposes a new approach to conduct simulation study of housing market within a mono-centric urban land use framework. In particular, to investigate the non-equilibrium dynamics of housing market, a (preemptive) queuing system with priority to search is designed to simulate the population flow. All housing units within the market are differentiated by its location (defined by its distance...
Modeling & Simulation (M&S) studies have been widely used in industry to gain insights into existing or proposed systems of interest. The majority of these studies focus on productivity-related measures to evaluate system' performance. However, this predominant focus on productivity may need to change since sustainability has become an increasingly important consideration in managerial discourse...
In this paper, five gold stocks in Chinese Shanghai and Shenzhen A-share and Comex gold futures are chosen to be the sample, for the purpose of analysing on the impact of the fluctuation of the international gold prices on the gold stocks in Chinese Shanghai and Shenzhen A-share. Using the methods of unit root test, Granger causality test, VAR model, impulse response function to comprehensively analyse...
This paper is concerned with a forecast of propriety of FX trading by quantitative analysis. The quantitative analysis in this paper uses a Naive Bayes model and a pair wise EPDW matrix. The Naive Bayes model employs a binomial distribution for the likelihood. Both the prior and posterior probabilities are assumed to be a beta distribution, so a conjugate distribution turns into the beta distribution...
Based on the perspective of demand motive of foreign exchange reserve, this paper constructed the measurement model of moderate scale of foreign exchange reserve based on multi-level demand and selected the actual data of China for measurement. Results have shown that the moderate interval of China's foreign exchange reserve was between 900 billion, and its excess scale was about...
Abstaining from voting is widespread in a voting process. Those candidates not be approved of are generally presumed to be disapproved in approval voting with abstention votes, which may ignore some genuine and meaningful information hidden in abstention votes. This paper constructs an analyzing model for abstention votes based on incomplete information system (IIS) and vague sets, and gives a new...
Under the shadow of economic bubble (EB) threat, development of major cities in the Yangtze River Delta Urban Agglomerations (YRDUA) not only depends on the flections of world economy, but also decides on their own resilience. Influencing factors on the YRDUA was large number, even some huge urban agglomerations (UA) was so favorably than some medium-sized countries in the land area, economy total,...
The common fraud events between the public accounting firm and the audited enterprise have occurred frequently, coupled with the lack of supervision and punishment, so that the quality of accounting information is constantly seriously questioned by the public. In this paper, I establish the principal-agent model of uncertainty and without supervision between the accounting firm and enterprise by making...
This paper will focus on the spatial structure of the economic network of Central Plains Economic Zone, 231 nodes which are at county level and above in this area are considered, their intensity of economic connection were computed based on gravity model in 1996 and 2010. Then, spatial pattern and evolution characteristics of the economic network of Central Plains Economic Zone are analyzed. The result...
We empirically investigate the payoff of signaling through aggressiveness in an online auction. To address our research question, we use a unique and very rich dataset containing actual market transaction data for approximately 7,000 pay-per-bid auctions. Our research design allows us to isolate the impact of aggressive bidding, used in an attempt to signal a high valuation to deter other auction...
Quick and highly efficient warning is critical in any emergency evacuation. From the issuing of warning until action taken by people in response, the entire course is a very complex process which is restrained by social, economic, population and other factors. To study the diffusion characteristics of warning in the social network environment as well as the relevant influencing factors, under the...
