The substations are important parts of modern electrical grids. In this sense, it is necessary to enhance the management efficiency and robustness of the substations. The one-key sequence control technology system could simultaneously control several subsystems and make use of their functions to automatically operate the substations. In this study, three subsystems, i.e., monitoring subsystems, error analysis subsystem, and decision support subsystem are designed in the one-key sequence control technology system. All the background information from the substations is monitored, checked, detected to find the potential threats. The decision support subsystem provides suggestive ways to handle these problems. Therefore, through the reasonable use of the one-key sequence control technology, the overall effectiveness and efficiency of the substations can be enhanced. With the development of artificial intelligence technologies, the one-key sequence control technology system can be further improved with more powerful functions.

The design of engineering systems involves the design of dependent subsystems and the integration of these into a whole. A typical system has the characteristics of being multileveled, multidimensional, and multidisciplined in nature. It is this complexity which causes problems for the designer in making well-founded decisions. A decision support technique has been developed which offers a structured facility for the design of the subsystems and for the modeling of the interaction which is present between subsystems. The method, employing optimization procedures, allows all aspects of the system design to be considered concurrently, to produce the "best" solution, as defined by the specifications. This is in contrast to the traditional design method, which is iterative and cyclic in nature, involving sequential reevaluation and refinement. In this paper, the effectiveness and efficiency of the decision support problem approach is demonstrated using the hierarchical characteristics of a design for a barge. The barge problem, though basic in form, is comprehensive in concept and tutorial in nature. As a formulation for "system" optimization, it uses a computer-based method for solution and illustrates the virtues of a multilevel/multidisciplinary approach to design and decision-making. It also exhibits the same characteristics and provides valuable insight into the solution of the more complex problems encountered in practical ship design.

The provisions of the arbitration procedural legislation on the pre-trial procedure for the settlement of the dispute are additional requirements to the filing to the court in comparison with civil procedural legislation. According to the legislator, on the one hand, these requirements encourage the independence of commercial organizations and individual entrepreneurs in the settlement of economic disputes, on the other hand, indicate the desire of the legislator to reduce the number of arbitration disputes and increase the effectiveness of justice. About three years have passed since the appearance of the norm in question and some conclusions can be drawn regarding its application by the courts. The authors of the article draw attention to the problematic aspects of law enforcement practice: categories of disputes when the application of pre-trial procedure is mandatory; compliance with the form, content, deadlines for submitting a claim; assessment by the court of the actions of the parties to resolve the dispute before going to court; overall effectiveness of the existing order. The authors conclude that the goal set by the legislator before the pre-trial procedure (an alternative pre-trial method for the resolution of disputes, designed to provide faster, less formalized and costly dispute resolution in comparison with the judicial process) is not achieved.

R&D activities normally require consortium formation due to the different areas of expertise involved in such activities. On the one hand, it is not trivial for a R&D entity to decide in which projects it should participate, or which are the adequate partners to form a consortium. On the other hand, acceptation of the Customer Relationship Management (CRM) Systems has become a reality for the industry and researchers in areas, such as marketing, communication, or computer science. These tools contain in their basic packages features to manage key company actives, including partners and clients. However, R&D environments involve special characteristics and traits, which require an extension of functionalities in order to be accurately covered. The increasing strength and usefulness of semantic technologies have led to innovative decision support processes and management of partners and R&D call for proposals. This work introduces an architecture that integrates R&D processes with the CRM philosophy.

Career counsellors have long known that occupational interests are often linked with abilities. We also know that if one has the ability, but not the interest, that ability will not be used. What happens, however, when one has an interest but not the right temperament or personality? I recently had the pleasure of seeing someone for career counselling who fell in this latter category. This individual (let us call her Ms S) came to my rooms with one burning question on her lips: “What's wrong with me? Why can't I keep a job? I was in my past job for 4 weeks and the one before that for 3 weeks. How do I hang on to a job?” Ms S had a secretarial background. She had been fired from her previous positions and was concerned whether she had the capacity to continue working in this field or whether she had somehow become too slow. After obtaining some background information, I asked Ms S to complete a battery of career counselling tests. Of special interest to this case was the results from both the Vocational Preference Indicator (VPI) and the 16 Personality Factor Questionnaire (16PF), which I shall discuss below.

During transports of large heavy cargo like jack-up rigs or semi-submersibles, the Motion Monitoring and Captain Decision Support system is a valuable tool to ensure a safe and economical voyage. Using the dynamic characteristics of the vessel in combination with 5-day weather forecasts and design limits like maximum accelerations at the cargo location, roll motion and/or leg bending moment, more and better information is available to the Master to choose a safe heading, speed and route. This way the best knowledge what to expect is contributing to the safety of cargo, transport vessel and crew. Besides use in heavy transport, this system is widely used on container ships, LNG carriers, all kinds of offshore vessels and many other types of floating structures. With daily communication, all important information is made available on internet to the operator’s main office, from which clients are informed with a comprehensive and concise overview of what is happening with their property. After the voyage, clients can be provided with the recorded Motion Monitoring data, which is valuable information for the lifetime assessment. The paper is presenting background information of the Motion Monitoring and Captain Decision Support system, a brief overview of methods used by the system and is describing the relations between transport vessel, main office and client and between the Transport Manual and the system. Results of two independent measurement systems are giving proof of high accuracy of the measurements. Comparison between measurements and predicted vessel response are shown and explained.

<p>Constrained target clustering (CTC) is proposed to support the targeting decision-making in the network centric warfare environment. When area targets are detected by sensors, it is required to decide the points at which a missile or bomb is aimed to achieve operational goals. CTC can determine the optimal numbers and positions of aiming points by transforming the targeting problem into clustering-based optimisation problems. The CTC formulations include objective functions and constraints in consideration of area targets, protected objects, target-level background information, lethal radius, and required damage rate. The numerical example shows how to apply the CTC formulation given a sample data set. In order to compare the effects of different constraints, the demonstration explores from an unconstraint problem to constrained problems by adding constraints. The results show that CTC can effectively decide the aiming points with consideration of both targets and capabilities of friendly weapons, and serve as a targeting decision support system in the network centric warfare environment.</p>

Recently, many security-related problems have gained increasing attention from a quantitative perspective. In this paper, we propose a game-theoretical approach to model the interaction between police forces and delinquents in public places. In the well-known Stackelberg game, a leader is faced with only one follower. However, in our application, the police are simultaneously faced with many offenders, who may be organized or act independently of each other. This application motivates the development of two games: a classical leader-follower interaction between police and organized criminals on the one hand and a novel approach between the leader and selfishly acting offenders on the other. It is of special interest that the effect of crime displacement under police surveillance be anticipated by the proposed models. Results using data from a simulated environment emphasise how these models can provide decision support for policing outperforming traditional strategies.
