In this paper, we will use coopetitive game theory to analyze a case of real coopetition among port companies, for what concerns loading and unloading of goods, within a competitive management scenario of marine transportation activities. Our research consists of the analysis of a study case involving coopetition between two real companies from which we obtained the financial and contractual data allowing us to define two modeling payoff functions, both of them based on real agreements and tariffs. We recognize actual coopetition and an asymmetric R&D alliance in this type of agreement, where a bigger enterprise deals with a smaller competitor, in order to capture more value from their activities. In particular, our model will show a precise coopetitive bi-dimensional trajectory within which we suggest, after a quantitative analysis, different kinds of solutions: the purely coopetitive solution, a Kalai-Smorodinsky solution and, finally, a transferable utility Kalai-Smorodinsky solution. Our methods provide specific strategy procedures determining win-win solutions for both.

Taking the fact that the fire explosion is the major danger during the transportation of flammable solid into account, the paper proposes a Fault Tree (FT) model about fire explosions affected greatly by packing, loading and unloading, vehicles, management and other factors, and converts the FT model into Bayesian Network (BN) one for quantitative analysis. Finally, the paper uses the data based on the BN model to prove that the model and algorithm are feasible.

Special Case

This paper presents a mathematical model of an ecological community in which different populations of organisms with interactions involving predator-prey encounters are considered. Here, a concept of nucleolar solution is used to represent the optimal best position in the ecosystem. Some notions of game theory is applied, where the players are the populations and the benefits from the interactions are represented by means of the payoff functions.

The background of this research is the increasing of marine transportation activities. The following of the activities is the improvement of community welfare nationwide. Accordingly the utilitation of all infrastructures related to sea transportation activities, should be improved in order to make the distribution of goods less expensine. The cost of loading and unloading by using shore crane and ship’s crane are different. The problem related to loading and unloading process is the unequality of operational cost between shore crane and ship’s crane. The main objective of this research is to compare cost and time performance of each of above mentioned cranes. The research focused on general cargo ship. The analysis was done by comparing of cost and time of operational of both type of cranes. The result of the study showed the shore crane is more suitable and efficient than ship’s crane from cost and time point of view.

SummaryThis paper is a brief history of game theory with its main theme being the nature of the decision makers assumed in the various stages of its historical development. It demonstrates that changes in the “image of man” nourished the developments of what many believe to be progress in game theory. The first stage, classical game theory, is defined by John von Neumann’s and Oskar Morgenstern’s pioneering book “Game Theory and Economic Behavior” which introduced the concept of individual rational players and focuses on conflicting interests. The second stage, modern game theory, is defined by the Nash player who is not only rational but, at least implicitly, assumes that all players are rational to such a degree that players can coordinate their strategies so that a Nash equilibrium prevails. The third stage, new game theory, is defined by the Harsanyi player who is rational but knows very little about the other players, e.g., their payoff functions or the way they form beliefs about other players’ payoff functions or beliefs. The Harsanyi player either plays a highly sophisticated epistemic game on the forming of beliefs or rests content with himself by imitating the observed successful behavior of other agents.

To reach the expecting goal of lower leakage ratio and longer operation life(lower wear ratio) for finger seal, great efforts have been made continuously to obtain good structure of finger seal with advanced optimization design technology. A cooperation Nash equilibrium mathematical model of multi-objective optimization for finger seal is presented in current work based on Nash equilibrium of game theory. In this solution, the reciprocal of leakage ratio and the wear ratio value for finger seal are thought as the payoff functions and the game is solved by genetic algorithm. The numerical simulation in the paper shows that the finger seal with better performances can be achieved by using Nash equilibrium method. This means Nash equilibrium method can be used as a new multi-objective optimization method for finger seal performances optimization.

Quantitative Results

Quantitative image analysis systems have been used for several years in research and quality control applications in various fields including metallurgy and medicine. The technique has been applied as an extension of subjective microscopy to problems requiring quantitative results and which are amenable to automatic methods of interpretation.Feature extraction. In the most general sense, a feature can be defined as a portion of the image which differs in some consistent way from the background. A feature may be characterized by the density difference between itself and the background, by an edge gradient, or by the spatial frequency content (texture) within its boundaries. The task of feature extraction includes recognition of features and encoding of the associated information for quantitative analysis.Quantitative Analysis. Quantitative analysis is the determination of one or more physical measurements of each feature. These measurements may be straightforward ones such as area, length, or perimeter, or more complex stereological measurements such as convex perimeter or Feret's diameter.

An important example of intracellular particles is encountered in silicosis where alveolar macrophages ingest inspired silica particles. The quantitation of the silica uptake by these cells may be a potentially useful method for monitoring silica exposure. Accurate quantitative analysis of ingested silica by phagocytic cells is difficult because the particles are frequently small, irregularly shaped and cannot be visualized within the cells. Semiquantitative methods which make use of particles of known size, shape and composition as calibration standards may be the most direct and simplest approach to undertake. The present paper describes an empirical method in which glass microspheres were used as a model to show how the ratio of the silicon Kα peak X-ray intensity from the microspheres to that of a bulk sample of the same composition correlated to the mass of the microsphere contained within the cell. Irregular shaped silica particles were also analyzed and a calibration curve was generated from these data.
