In course of the German power system transition to a higher share of renewable energy sources decentralized activities constitute a major driving force for the growth of renewable energy capacity. In this context plural activities and initiatives on the local and regional level are followed to develop concepts for an efficient and sustainable regional energy supply. To achieve these goals various objectives has to be simultaneously accomplished. Generally, these objectives contradict to each other and cannot be handled by a single optimization technique. This paper proposes a multiobjective (MO) optimization approach for identifying efficient DG generation portfolios regarding multiple objectives. The methodology presented allows the planner to decide the best trade-off between the self-supply degree, environmental impact and electricity generation cost. The proposal applies, in a study case, a MO genetic algorithm that allows identifying a set of non-inferior Pareto-optimal solutions.

The task of a capacity allocation policy is to determine the optimal quantity of capacity that has to be shared among the transmitting entities. In this work the allocation problem is modelled by the multiobjectiveprogramming (MOP) theory. In particular, an allocation criterion based on the L_p-problem is proposed to find out a capacity allocation, among Earth Stations, representative of a compromise if Packet Loss Probability and Transmitted Power are taken into account as performance metrics. The paper also discusses the existence of a capacity allocation, called Capacity Bound, on which the performance converges independently of the overall capacity available C_(TOT)- A performance analysis, carried out through simulations and under different satellite channel conditions, is finally proposed to investigate the allocation criterion performance and to show the Capacity Bound existence.

The Decision Support Systems (DSS) were widely applied to the field of multi-Criteria Decision Aid (MCDA). In fact, the most popular MCDA aggregating procedures are those supported by a DSS. Our literature review reveals that the multi-Criteria Decision Support Systems (MCDSS) have applied in several fields such as: Production and Operation Management, Finance, Education, Human Resources, Real Estate and multi Media. The aim of this paper is to provide a state-of-the Art and a classification by field of MCDSS applications.

A resource allocation model (RAM) for not-for-profit organization in the framework of Data Envelopment Analysis (DEA) was introduced by Zhang and Cui ([1]). The model is an inverse formulation to the DEA model , as pointed in paper [2], and can be transformed into a parametric linear programming problem. Also a multi-objective programming problem was introduced in [2] to solve RAM when the efficiency index of the discussed organization is strictly less than one. In this paper, inadequacy of the original RAM model is discussed and then a revised new model is presented. The new model can be transformed into a multi-objective programming problem or a linear programming problem for any efficiency index value an organization has.

Due to the economic spillover effect in Higher Education, thus higher education can not be fully market-oriented. There is market failure in the economy of higher education from the perspective of whether demand or supply, it is impossible to achieve the situation of Pareto optimal allocation for the higher education resources rely solely on fund allocation. In view of this, this paper present a multi- objectiveprogramming model for balanced allocation of resources in china regional higher education, and we used the Pareto genetic algorithm to get the solution of the model. The method does not need artificial weighting factors, it is a natural evolutionary calculation method. We explored the Pareto Equilibrium configuration for regional higher education resources. We analyzed the sensitivity of the model by using the cost-benefit approach. The results show that this paper's approach is a generally applicable and easy way for the achievement of the regional higher education resources in a balanced situation.

Firstly we make a brief introduction of the algorithm and astringency of existing model free controller and then in this paper propose two methods to improve the existing controller. On the one hand, a model free controller with dead zone is presented in order to avoid frequent movement of control action and eliminate the vibration of the system in some conditions. On the other hand, the problem of model free controller with constraints is considered. This problem is reduced to a multi-objective programming (MOP) and a multilevel ordering method is used to accomplish the programming with respect to the sense of the control problem. The effectiveness of the improved controllers is verified via two numerical examples.

Usually, there are different objectives and units of measurement related to technique, cost and time in R&D process, which make it more complicated to select R&D methods, let alone decision making with comprehensive consideration of the balance among them. The theory of multi-objective programming, mixed integer programming and critical path is herein used to establish a multi-objective programming model. In this model, constraints are based on the respective objectives of the factors and the balance among them while the objective function is minimizing the sum of the weighted relative deviation of each object. Besides being used to optimize decision making in the R&D process of complicated equipment, this model is a general form and can also be used in the development of other projects in other fields.
