Using Social Network Analysis, this study investigates whether a board interlocking network exists among the French listed companies (we consider the French Financial Indices CAC 40 and SBF 250) and how this network differs between CAC40 companies and SBF250 companies. Moreover, this research focuses on whether a firmâs centrality is associated with its size. The results suggest that (1)...
Futures traders usually face to the uncertainties of prices and trading quantities of the underlying commodities. The hedging decision is also affected by the agency condition in the trading process. This note works on the above issues by constructing the models with proper considerations. Empirical research is implemented by using the data of fuel oil futures from Shanghai futures exchange. It turns...
This paper deals with a short-term liner ship fleet Planning (LSFP) problem with container shipment demand uncertainty. Assuming that container shipment demand between any two ports on each ship route follows a normal distribution, this paper develops an integer linear programming model with chance constraints for the LSFP problem and proposes a two-phase heuristic algorithm for solving the large-scale...
since the concept of inter-organization imitation was brought up, researchers mainly use a theory to explain the imitation behavior of internationalization of service multinational corporations, which is not enough to interpret the generating mechanism. Actually, because of the multi-reasons of the imitation of internationalization, it is not suitable to explain the phenomenon in one specific aspect...
How can the enterprise group be formed? Can it be explained by global mechanisms or models? The relationship among enterprises is described as relationship degree. Thus, correlation network is built upon enterprise group. The types of relationship among group or between groups are entitled as group inner energy and group outer energy. A 0/1 integer programming model is established for enterprise group...
Sustainable manufacturing can be expressed as the consideration of economical, environmental, and societal impact during product design for the entire life cycle. Although interest in nanomaterials and nanodevices has been growing rapidly, the uncertainty about human health and environmental impact of the nanomaterials still exits. Moreover, current nanomanufacturing techniques have negative environmental...
In the development course of smart grid, risk evaluation can be applied for smart grid to lead the decision maker to achieve scientific plan, so that blind investment and significant risk loss may be avoided. Aiming at the reasons and benefits of risk management for smart grid in this paper, firstly, different risk of smart grid can be identified from five aspects, including financial risk, security...
The main goal of Transmission Network Expansion Planning (TNEP) is determination of the number, time and location of new lines to be added to transmission network. Up to now, different methods have been used to solve the static TNEP (STNEP). In most of them, this problem is implemented regardless of power loss and the uncertainty in the load demand. With respect to the importance of these two parameters...
With the advent of power system restructuring, there is now competition on the generation activity and the generation mix changed in many countries with the incentives to induce investments in renewables, in many cases, using volatile primary resources. Given this increase of the installed capacity in wind parks and PV stations as well as in hydro stations (as a way to address the mentioned volatility),...
Current guidance for the USA's defense acquisition processes have been formalized in the Joint Capabilities Integration and Development System (JCIDS). The enhanced requirements from these policies and procedures have made system of systems (SoS) acquisitions more difficult as defense agencies try to implement the updated practices. Many of the associated challenges are a result of the fundamental...
This article proposes a novel method for comparison among interval-valued intuitionistic fuzzy values (IVIFVs). Two distinctive score functions are utilized to distinguish IVIFVs based on the boundary values of interval-valued membership and non-membership. The uncertainty included in the numerical intervals of membership and non-membership for an IVIFV is well treated as uniform potential instead...
As software houses align themselves to serve clients operating in rapidly changing business environments, they start putting more emphasis on increasing their agility. However as a precursor to this, there is a need within an organization to measure and monitor its agility. The clients also would be interested to know the level of agility of their vendors. While the need for an effective metric is...
One of the emerging sweet-spots in business intelligence (BI) and business performance management (BPM) projects is the design of metrics (dashboards) in such a way that they balance the need for "inward focused" operational management with the need for "outward-focused" strategic management. Unfortunately, hitting this sweet spot often proves to be a difficult process, particularly...
Stochastic programming and robust optimization are disciplines concerned with optimal decision-making under uncertainty over time. Traditional models and solution algorithms have been tailored to problems where the order in which the uncertainties unfold is independent of the controller actions. Nevertheless, in numerous real-world decision problems, the time of information discovery can be influenced...
In the paper, we first put forward an uncertain transportation model for transhipment permitted when the pessimistic value criterion is true. Secondly, balanced condition of an uncertain transportation model is presented. Lastly, we conduct the numerical experiments.
Organisations communicate through verbal, written and electronic channels for the free flow of information. The ability to support this free flow or quality of information impacts on organisational efficiency. Using social network analysis, the paper compares and contrasts the social networks created by verbal, written and electronic communication channels in three companies. The created social networks...
Risk is an important and ubiquitous concept that plays a crucial role in decision makings across domains. Risk is also a vague notion that carries different meaning under different domain context and perspectives. This paper aims to provide a formal generalised definition of risk based on the possible world paradigm and expected utility theory and the meanings of risk from both qualitative and quantitative...
China issued a new set of Accounting Standards for Business Enterprises (ASBE) in 2006 and this ASBE are substantially in line with IFRS. Based on the cross-cultural work of Hofstede, we figure out different results of cultural values between China and world average and these cultural factors make accounting follow different patterns in different parts of the world, so a few important differences...
Current dynamic and turbulent markets require flexible business processes that increasingly depend on fast and reliable information flows between heterogeneous companies. This relies on innovative types of integrated applications on all layers -- technological, organizational and process-related -- and a holistic managerial framework to establish a smoothly operating layer integration. Thus, we first...
The international financial crisis highlights the payment risk in exporting goods, especially overdue and bad debts by credit risk and transaction exposure by exchange risk. Although risk management against international payment risk has received great attention in both literature and corporate practice, most of them just focus on handling external technical failures rather than building an effective...
