Multiobjective Optimal Control

In the present paper a problem of optimal control for a single-product dynamical macroeconomic model is considered. In this model gross domestic product is divided into productive consumption, gross investment, and nonproductive consumption. The model is described by a fuzzy differential equation (FDE) to take into account imprecision inherent in the dynamics that may be naturally conditioned by influence of various external factors, unforeseen contingencies of future, and so forth. The considered problems are characterized by four criteria and by several important aspects. On one hand, the problem is complicated by the presence of fuzzy uncertainty as a result of a natural imprecision inherent in information about dynamics of real-world systems. On the other hand, the number of the criteria is not small and most of them are integral criteria. Due to the above mentioned aspects, solving the considered problem by using convolution of criteria into one criterion would lead to loss of information and also would be counterintuitive and complex. We applied DEO (differential evolution optimization) method to solve the considered problem.

Tourism shows a significant contribution to foreign exchange and regional income in Indonesia. Defined as a priority and leading sector in the RPJMD, tourism development in the Regencies and the Province of Gorontalo must measure the results, benefits and impacts for all stakeholders. Contribution to regional income (PAD) and the composition of internal and external factors in each of the leading destinations is needed for the purpose of determining the strategy and policy of sustainable tourism development. The study concluded that tourism sector was relatively small in its contribution to each PAD total by Regencies in Gorontalo Province. The low of PADsp is relevant to the low occupancy rate (TPK) of the hotel and the length of stay (LoS). The lack of retribution income from recreation and sports spot is relevant to the lack of activities to support the attractiveness such as art and cultural attractions and local products that can be souvenirs for tourists. Infrastructure facilities at leading tourism objects are relatively incomplete or do not meet tourism standards. The low of PAD, TPK LoS can also explain that the increase in tourists to Gorontalo is only a transit to the other tourist objects outside of Gorontalo Province.Keywords: Tourism, Leading Sector, Gorontalo, Income, Swot Analysis

On the Mutual Compatibility of Democracy and Marxian Socialism

Much of the high politics of our time is affected by the hostility and suspicion that pervade relations between the Western democracies and the socialist world. Is it possible that the hostility and suspicion are misplaced, and that the two world systems can find a common ground on which to acknowledge each other as compatible co-denizens between whom there is no difference so potent that the being of one must be a reproach to the being of the other? With a view to this question, I wish to ask whether it is possiblefor a Marxist society to be democratic or for a democracy to elect Marxism or to elect to remain Marxist. Putting the question in the form, “Is it possible …” would enable us to answer it by pointing to even one example of a Marxist democracy, thus to dissolve what seems like a theoretical matter in an empirical medium.

Asian History

Since the end of World War II the study of Southeast Asia has changed unrecognizably. The often bitter end of colonialism caused a sharp break with older scholarly traditions, and their tendency to see Southeast Asia as a receptacle for external influences—first Indian, Persian, Islamic or Chinese, later European. The greatest gain over the past forty years has probably been a much increased sensitivity to the cultural distinctiveness of Southeast Asia both as a whole and in its parts. If there has been a loss, on the other hand, it has been the failure of economic history to advance beyond the work of the generation of Furnivall, van Leur, Schrieke and Boeke. Perhaps because economic factors were difficult to disentangle from external factors they were seen by very few Southeast Asianists as the major challenge.

Based on the strong coupling and interval requirement of multiple quality indices, the interval-index-oriented optimization method is proposed to effectively realize the optimal control of alumina blending process. Firstly, the lexicographic interval goal programming model is built to describe the process requirements for quality indices. Then, based on the characteristics of the programming model, a kind of classificatory knowledge base is constructed by using the empirical knowledge accumulated in long-term production and the expert reasoning strategy is proposed to realize the optimal control of quality indexes with interval constraints. The results of industrial application shows that the proposed method can realize the optimal control of quality indices. It provides a good optimization mode for other blending processes of nonferrous metal production.

Many optimization problems in applications can be formulated using several objective functions, which are conflicting with each other. This leads to the notion of multiobjective or multicriterial optimization problems. Here, we investigate the application of the Euclidean reference point method in combination with model-order reduction to multiobjective optimal control problems. Since the reference point method transforms the multiobjective optimal control problem into a series of scalar optimization problems, the method of proper orthogonal decomposition (POD) is introduced as an approach for model-order reduction.

Novel Approach

Abstract The classic win-win has a key flaw in that it cannot offer the parties with right amounts of winning because each party believes they are winners. In reality, one party may win more than the other. This strategy is not limited to a single product or negotiation; it may be applied to a variety of situations in life. We present a novel way to measure the win-win situation in this paper. The proposed method employs the Fuzzy logic to create a mathematical model that aids negotiators in quantifying their winning percentages. The model is put to the test on real-life negotiation scenarios such as the Iranian uranium enrichment negotiations, the Iraqi-Jordanian oil deal, and the iron ore negotiation (2005-2009). The presented model has shown to be a useful tool in practice and can be easily generalized to be utilized in other domains as well.
