Opis:
The development of e-commerce site operators in Indonesia is now faced with intense competition for defending the market segment, especially regarding how e-commerce sites are attracting consumers through specic marketing strategies. This study implements a decision support system approach to help marketers to determine price discount alternatives using the Elimination et Choix Traduisant la Realite (ELECTRE) method. The ELECTRE method is widely recognized for having good performance in analyzing customer behavior criteria; however, there is little information about discount analysis using the ELECTRE method. This study implements a method for consumer behavior simulation that can be aected by the criteria to make a purchase on a simulated e-commerce website. Our model estimates three parts of the matrices' analysis: (a) average value of discounted price (DP); (b) average value of pro- duct brand (PB); and (c) average value of purchase decision (PD). We used these as the main alternatives; e.g., price discounts as rst alternative (A1), brand discount as second alternative (A2), and purchase discount as third alternative (A3). Based on the results of the dominant aggregation matrix, the study found that the results are dominated by brand discount (A2). In other words, it is recommended for the decision maker to focus their discount on certain brands more precisely as a marketing strategy than price discount or purchase discount.

Opis:
A prototype for an operational ship routing Decision Support System using time‐dependent meteo‐oceanographic fields is presented. The control variable is ship course, which is modified using a directional resolution of less than 27 degrees. The shortest path is recovered using a modified Dijkstra’s algorithm. Safety restrictions for avoiding surfriding and parametric rolling according to the guidelines of the International Maritime Organization (IMO) are implemented. Numerical experiments tailored on a mediumsize vessel are presented and perspectives of development of the system are outlined.

Opis:
School is a natural context for development in which the communicative strategies used by teachers when interacting with students are essential for the development of communicative and linguistic competence. The objective of this study was to construct, implement and validate a first version of a self-assessment and decision-making tool on the teaching of oral language at school. It is an adaptation of the Oral Language Assessment in the School Context Scale (Escala de Valoración de la enseñanza de la Lengua Oral en contexto Escolar-EVALOE) (Gràcia et al., 2015) based on the use of the Conversational Methodology. This is a multiple case study focusing on four teachers (1 from an ordinary school, 2 from a rural school and 1 from a special education school). For six months, the teachers self-assessed their teaching practices with the tool, made decisions to improve it, and introduced changes in their classes. The researchers observed five class sessions of each teacher, assessed them with the same tool and each teacher-researcher pair conversed and reflected on the classes in five meetings throughout the semester. The results show that, in spite of the fact that there were important differences between teachers, the EVALOE - Decision Support System (EVALOE-SSD) is a useful tool that facilitates self-assessment, decision-making and the introduction of changes in the classes in order to promote the development of communicative and linguistic competence in the students. The analysis identified elements that can be improved and that will be considered during the review of the tool.

Situation awareness is the key element of the decision-making process. In navigation safety domain, monitoring, control, assessment of dangerous situations, support of operators of decision-making support system should be implemented in real time. In this paper we present the problem of situation awareness applied to navigation safety control. The paper considers existing models of situation awareness and ontology-based approach for maritime situation awareness. We introduce the situation concept using infons. Finally, we give an example how use these methods for design and creation of decision-support system for navigation safety control.

Opis:
A ship’s autopilot adjustment is a matter of utmost importance since it affects its safety, command as well as fuel and time efficiency. A number of methods have been developed in order to cope with this issue usually based on models that simulate the weather conditions and adjust the device accordingly. Some of them have a considerable degree of success but none dealt with the problem completely. The main obstacles are the difficulty of simulating the infinite weather and loading conditions and to properly represent them with mathematical equations or rules. This paper describes a method of selecting the best out of a pre-existing set of configurations, taking into account any weather situation, loading condition and type of ship. Moreover, the selected configuration can improve itself during the entire life cycle of the vessel, since it fine tunes its properties for better results. This approach uses Case Based Reasoning as its core technology and is a part of a hybrid system that analyses and solves prefixed problems of maritime interest.

Opis:
Ship collision risk index is the basic and important concept in the domain of ship collision avoidance. In this paper, the advantages and deficiencies of the various calculation methods of ship collision risk index are pointed out. Then the ship collision risk model based on complex plane, which can well make up for the deficiencies of the widely-used evaluation model proposed by Kearon.J and Liu ruru is proposed. On this basis, the calculation method of collision risk index under the encountering situation of multi-ships is constructed, then the three-dimensional image and spatial curve of the risk index are figured out. Finally, single chip microcomputer is used to realize the model. And attaching this single chip microcomputer to ARPA is helpful to the decision-making of the marine navigators.

Zadanie szeregowania ofert, w formie studium przypadku, zrealizowano w informatycznym systemie klasy DSS (ang. Decision Support Systems) opracowanym w środowisku akademickim Szczecina (DSS 2.0, aut.: R. Budziński, J. Becker).
In the article presented the integration of knowledge sources for the ranking of business proposals. Assumptions are that criteria may be derived from a group linguistic assessment (or mixed), de-fragmented into smaller components and evaluated altogether (through the preferences of these ingredients), and transposed to the desired output figures (such as binary form). A task of scheduling offers (in a form of case studies) was conducted in an information system of DSS class (Decision Support Systems) built in academic environment of Szczecin (DSS 2.0, aut.: J. Becker., R. Budziński).

Opis:
A multimethod approach to the multicriteria analysis and assessment of objects (rankings, grouping, econometric assessments) have been presented. This issue is a field of research and engineering associated with the construction and application of a computerized decision support system (DSS 2.0). In terms of the proposed approach, the functionality of the developed prototype has been illustrated based on a practical example of the assessment of employees and the analysis of remuneration. The Electre TRI method of grouping derived from a relational model complements ranking methods well (e.g., AHP) based on the functional model. Grouping reveals cases, where all or the vast majority of objects in a ranking were clustered within one class (e.g., in the best or the worst one).

Opis:
Decision Support Systems are powerful tools to help support making decisions. However, they are known to be customized for a specific purpose and can rarely be reused. Moreover, they do not support complex situations sufficiently. Our work addresses this challenge and consists in building a DSS that aims to help emergency managers to manage cases of crisis. The DSS is designed to be flexible and adaptive, so that it may be applied on different subjects of studies and whose behaviour may change with the change of its environment. We endowed it therefore with a multiagent layered core whose role is to represent dynamically and in real time the current situation, to characterize it and to compare it with past known scenarios. The final result of the DSS will help decision-makers to analyze the current crisis and its possible evolution. The RoboCupRescue simulation system is chosen as a test bed to illustrate and to test this approach.
