In operations research, there are methodological tools included in decision theory that can help decision-makers understand and systematize the decision-making process. Decisions can be classified either as mono-criterial, when only one criterion or goal is considered to evaluate its performance or multicriterial, which takes into account the interaction between two or more goals or criteria that can be in conflict. Natural resource management and finance are some important examples where the implementation of this type of tools has benefited the decision-making process because they allow a number of criteria or objectives to be weighted in a transparent manner to assist when one or more decision-makers are involved. Despite this, its application was not common in aquaculture;however, in recent years, efforts have increased exponentially. This work seeks to identify opportunity areas for development of new aquaculture-related research through the implementation of multicriterial decision-making methods (MCDM). To achieve this, a comprehensive bibliometric analysis was performed to detect MCDM applications that have been implemented in aquaculture industry (24 documents that were grouped into eight applications). Later, this information was complemented through the analysis of selected applications in natural resources management, specifically in fisheries, animal husbandry and agriculture. We propose 23 research topics relevant to the aquaculture industry that can be addressed by the methodologies in MCDM.

The development of technology accelerates the life cycle of products and the rate of product substitution. Dynamic random access memory (DRAM), which is characterized by generation substitution, is an innovation in technology development that enhances competitive capabilities. In this study of the DRAM industry, the Gompertz model, traditional logistic growth model, Norton and Bass model, and fuzzy piecewise logistic growth model are applied to predict the growth trends of eight generations of the DRAM market. The results show that only the fuzzy piecewise logistic growth model and the Norton and Bass model can effectively forecast the growth trends of coming generations in the DRAM industry. Of these two models, only the fuzzy piecewise logistic growth model that detects change points can be used to reasonably explain the phenomenon and status of generation replacement in the DRAM industry at particular times, and provide an overview of the market situation.

In the real world we are confronted with many cases where the ratio of input/output data is so important for managers, so in this regard we cannot use traditional Data Envelopment Analysis (DEA) models to evaluate the efficiency of decision -making units (DMU) and we should use DEA models based on ratio data. To get the corresponding benchmark for each inefficient decision -making unit, we need to reduce and increase the inputs and outputs, respectively, and get the unified projection of the decision maker unit on the efficiency frontier. In this paper we present a multi -objective linear programming (MOLP) model for evaluating efficiency based on defining the production possibility set in the presence of ratio data and to get the corresponding benchmark to each decision -making unit DMU. We use the Zionts and Wallenius (Z-W) interactive method to solve the MOLP model presented. Using the target setting by manager among the solutions resulting from the MOLP problem, we choose best solution according to the managers' preferences as benchmark and at the end we present the results of the research.

During the flight, the crew might consider modifying their planned trajectory, taking into account currently available information, such as an updated weather forecast report or the already accrued amount of delay. This modified planned trajectory translates into changes on expected fuel and flying time, which will impact the airline's relevant performance indicators leading to a complex multiple-criteria decision-making problem. Pilot3, a project from the Clean Sky Joint Undertaking 2 under European Union's Horizon 2020 research and innovation programme, aims to develop an objective optimisation engine to assist the crew on this process. This article presents a domain-driven approach for the selection of the most suitable multiple-criteria decision making methods to be used for this optimisation framework. The most relevant performance indicators, based on airline's objectives and policies, are identified as: meeting on-time performance, leading to a binary value in a deterministic scenario;and total cost, which can be disaggregated into sub-cost components. The optimisation process consists of two phases: first, Pareto optimal solutions are generated with a multi-objective optimisation method (lexicographic ordering);second, alternative trajectories are filtered and ranked using a combination of multi-criteria decision analysis methods (analytic hierarchy process and VIKOR). A realistic example of use shows the applicability of the process and studies the sensibility of the optimisation framework.

In order to resolve non-protruding-multi-programming, a new direct algorithm of multi-programming optimization is presented in is paper. A new prior-order number is put forward and the genetic algorithm is used to select resolutions that possess maximal prior order. In this way the algorithm can resolve the multi-programming possessed that the feasible region is indefinite aggregate. The algorithm offers a feasible method to resolve non-protruding-multi-programming.
