Opis:
This article describes the impact of a pilot’s situational awareness (SA) on the quality of decisions that are made by him or her. Situational awareness has been defined as a state and as a process. The article also refers to how the situational awareness and the decision-making process interact. The decision-making process and its components have been defined. Based on author’s own research as well as conclusions drawn from the subject’s literature, the importance of an acceptable SA level for the correct progress of a pilot’s decision-making process (and the likelihood of making a good decision) has been pointed out.
W artykule opisano wpływ świadomości sytuacyjnej pilota (SA) na jakość podejmowanych przez niego decyzji. Świadomość sytuacyjna została zdefiniowana jak stan i proces. Artykuł odnosi się również do tego, jak świadomość sytuacyjna oraz proces podejmowania decyzji oddziałują na siebie wzajemnie. Zdefiniowano proces podejmowania decyzji i jego komponenty. Przedstawiono również, na podstawie badań autora i wniosków wyprowadzonych z literatury tematu, znaczenie dopuszczalnego poziomu świadomości sytuacyjnej pilota dla poprawnego przebiegu procesu podejmowania decyzji i prawdopodobieństwa podjęcia poprawnej decyzji.

Opis:
Adaptive (or actor) critics are a class of reinforcement learning algorithms. Generally, in adaptive critics, one starts with randomized policies and gradually updates the probability of selecting actions until a deterministic policy is obtained. Classically, these algorithms have been studied for Markov decision processes under model-free updates. Algorithms that build the model are often more stable and require less training in comparison to their model-free counterparts. We propose a new model-building adaptive critic, which builds the model during the learning, for a discounted-reward semi-Markov decision process under some assumptions on the structure of the process. We illustrate the use of our algorithm with numerical results on a system with 10 states and a real-world case-study from management science.

Opis:
The problem of improving the decision-making process in highly hierarchical organizations is the subject of reflection and discussion of many authors. The aim of the paper is to signal the need to introduce changes not only in the organizational structure of the Police of the Republic of Poland, maximizing the rationality of the decision-making process in the conditions of deep civilizational transformations, but also introducing modern methods of information management. The proposed directions of changes will increase the effectiveness of the functioning of the Police organizational units in the conditions of increasing turbulence of the state environment in the 21st century.

Opis:
The introduction of a simulator of Police actions in crisis situations to police training of command skills made it necessary to know the ongoing relationship between training on the simulator and the actual actions of the Police. Visualisation of the effects of decisions taken by commanders in a virtual simulation environment, ending in most cases in the escalation of the threat, trigger off analytic mechanisms and awareness of responsibility for the life and health of people and the officers carrying out commands issued by commanders and other persons taking part in the simulation. Simulation training provides the opportunity to observe the ongoing relationship between cells of the command structure adopted by commanders, depicting among others, the sources of errors and threats of destabilisation of commanding process. There are various scenarios that are possible to play including elements such as: police riot, crowd aggression level, and weather conditions. Based on the feedback from simulation training participants, who are mostly those responsible for commanding processes while performing daily duties, it is reasonable to say that the training conducted on the Police simulator in crisis situations allows the commanding skills and abilities to be significantly shaped. What is more, as the simulator is a universal tool, it enables cooperation training to be conducted with non-police entities, the fire brigade, medical emergency, city guard, and crisis management teams.

Exploration-Exploitation Dilemma
Opis:
Balancing exploratory and exploitative behavior is an essential dilemma faced by adaptive agents. The challenge of finding a good trade-off between exploration (learn new things) and exploitation (act optimally based on what is already known) has been largely studied for decision-making problems where the agent must learn a policy of actions. In this paper we propose the engaged climber method, designed for solving the exploration-exploitation dilemma. The solution consists in explicitly creating two different policies (for exploring or for exploiting), and to determine the good moments to shift from the one to the other by the use of notions like engagement and curiosity.

Opis:
Next-generation of High-Speed Machining (HSM) systems demand advanced features such as intelligent control under uncertainty. This requires, in turn, an efficient administration and optimization of all system's resources towards a previously identified objective. This work presents an optimization system based on Markov Decision Process (MDP), where an intelligent control guides the actions of the operator in peripheral milling processes. Early results suggest that MDP framework can cope with this application, yielding several benefits, which are discussed in detail. Future work will address the full integration of the developed optimization scheme within a commercial machining center.

Legal Aspects of Lobbying in Decision-Making Processes of Public AdministrationThe process of decision-making in public administration is multifaceted, with the deci-sion being the result of complex proceedings aimed to settle a case or reach a specific goal. Public administration works in this area mainly in the legał environment, but not only. The decision-making process is determined by social conditions and includes agency of various persons whose conduct and actions lead to certain conseąuences. Due to the different tasks of public administration, its activity is not merely a result of the will of a given body but it can also be initiated by applicants interested in the attainment of defined objectives, including through lobbying. The essence of lobbying is to influence, within the confines of law, decisions of public authorities in a particular direction. In Poland, lobbying is nów an institution regulated by the Act of 7 July 2005 on Lobbying Activity in the Lawmaking Process (OJ No 169, item 1414).Lobbying is also very common in the European Union, where the phenomenon is not only acceptable, but even desirable.Lobbying is seen as bringing benefits for both parties consulted. Therefore, at the level of the European Union, certain standards have been determined defining the scope of relations between the Community Institutions

Opis:
Appropriate product categorization in distribution centres is important for business success because of the possibility of intuitive product finding by the picker and increased product movement. Both of these factors result in the operational efficiency of the distribution centre. The goal of this paper is to explore a model of shelf space dimensioning of storage location on a rack with vertical and horizontal product categorization in a distribution centre, where the aim is to increase total product movement/profit from all shelves of the rack. This is controlled by a packer who must complete orders by getting the goods from shelves and picking them to the container. In this problem, we develop two heuristics and compare the archived results to the CPLEX solver. The average profit ratios of both heuristics are high and approximately equal to 99%. In 10 cases, optimal solutions have been found by heuristics. The total number of possible solutions to be checked for the largest instance was reduced from 1.33 ·10156 to 1.19 ·107 thanks to the heuristic rules.

Opis:
Distribution centres are the important elements of modern supply chains. A distribution centre stores and ships products. In this paper, we investigate the model of the dimensioning of shelf space on the rack with vertical and horizontal product categorisation in a distribution centre, where the objective is to maximise the total product movement/profit from all shelves of the rack which is being managed by a packer who needs to complete orders selecting the products from the shelves and picking them to the container. We apply two newly developed heuristics to this problem and compare the results to the optimal solution found by the CPLEX solver. There are 8 steering parameters that allow for reducing the search space implemented in heuristics. Among them are parameters that decrease the number of prod- ucts on the shelves, the category width range for assigning most space for the most profitable products within the category, two versions of steering parameters for the number of generated product allocations, the step parameters for the intensity of solution diversification, and the movement/profit below which the solutions are not generated. The computational results are presented and indicate that higher-quality solutions can be obtained using the new heuristics. In 10 from 15 tests, both heuristics can find optimal solutions without exploring the whole solution space. For the rest test sets, the solutions received by heuristics are not less than 92.58%.

Opis:
In this paper we introduce a new modeling paradigm for developing a decision process representation called the Colored Decision Process Petri Net (CDPPN). It extends the Colored Petri Net (CPN) theoretic approach including Markov decision processes. CPNs are used for process representation taking advantage of the formal semantic and the graphical display. A Markov decision process is utilized as a tool for trajectory planning via a utility function. The main point of the CDPPN is its ability to represent the mark-dynamic and trajectory-dynamic properties of a decision process. Within the mark-dynamic properties framework we show that CDPPN theoretic notions of equilibrium and stability are those of the CPN. In the trajectory-dynamic properties framework, we optimize the utility function used for trajectory planning in the CDPPN by a Lyapunov-like function, obtaining as a result new characterizations for final decision points (optimum point) and stability. Moreover, we show that CDPPN mark-dynamic and Lyapunov trajectory-dynamic properties of equilibrium, stability and final decision points converge under certain restrictions. We propose an algorithm for optimum trajectory planning that makes use of the graphical representation (CPN) and the utility function. Moreover, we consider some results and discuss possible directions for further research.
