We apply a non-classical four-valued logic in the process of reasoning regarding strategies for cops in a modified game of “Cops and Robber” played on a graph. We extend the game by introducing uncertainty in a form of random failures of detecting devices. This is realized by allowing that a robber can be detected in a node only with the given probability PA. Additionally, with the probability PF, cops can be given a false-positive, i.e., they are informed that the robber is located at some node, whereas it is located somewhere else. Consequently, non-zero PFintroduces a measurement noise into the system. All the cops have access to information provided by the detectors and can communicate with each other, so they can coordinate the search. By adjusting the number of detectors, PA, and PFwe can achieve a smooth transition between the two well-known variants of the game: “with fully visible robber” and “with invisible robber”. We compare a simple probabilistic strategy for cops with the non-parametric strategy based on reasoning with a four-valued paraconsistent logic. It is shown that this novel approach leads to a good performance, as measured by the required mean catch-time. We conclude that this type of reasoning can be applied in real-world applications where there is no knowledge about the underlying source of errors which is particularly useful in robotics.

Purpose – The improvement of routing operations performance has been of great concern for organisations. This has led to the development of alternative lean-based methods, however the literature research on the applications of lean thinking in the transportation sector is still considered rather limited. The purpose of this paper is to present a lean thinking and simulation-based approach to improve the efficiency of warehousing and routing operations. Design/methodology/approach – The paper reviews the existing literature in the area of lean transportation and then presents and applies a novel approach to improve the vehicle routing operations of a Mexican firm. The proposed approach suggests the classification of wastes into those relevant to transport operations, their identification through a transportation value stream mapping study, and the use of the transportation overall vehicle effectiveness (TOVE) index for the measure of the overall performance of the transport operations. Findings – The results obtained from the case study indicate that the proposed approach is an effective alternative for the improvement of vehicle routing operations as the number of routes decreased from 30 to 22 and the distance travelled by 32 per cent. Similarly, the average number of clients served by each route increased by 23 per cent as well as the TOVE index increased from 6.9 to 19.3 per cent. The TOVE component measures of vehicle performance and operating availability efficiencies also increased significantly while quality issues, in the form of number of customers not served per route, were reduced from six to zero. Originality/value – The improvement of routing operations performance has been traditionally addressed through operations research and mathematical modelling approaches. This paper presents an alternative and novel lean thinking and simulation-based approach to improve the efficiency of routing operations.

This paper presents a novel method for detecting locations of damages in thin walled structural components made of fiber reinforced composites (FRC). Therefore, the change of harmonic distortion, which is found by current research to be very sensitive to delamination, under resonant excitation will be derived from FEM-simulation. Based on the linear modal description of the undamaged structure and the damage-induced nonlinearities represented by a nonlinear measure, two spatial damage indexes have been formulated.The main advantage of this novel approach is that the information about the defect is represented mainly by changes in the modal harmonic distortion (MHD), which just needs to be measured in one (or few) structural points. The spatial resolution is given by the pairwise coupling of the MHD with the corresponding mode shapes.

Objective. The implementation of simulation-based training in residency programs has been increased, but the transferability of surgical skills in the real operating room is not well documented. In our survey, the role of simulation in surgical training will be evaluated. Study Design. In this systemic review, randomized control trials, which assessed the transferability of acquired skills through simulation in the real operating setting, were included. A systematic search strategy was undertaken using a predetermined protocol. Results. Eighteen randomized clinical trials were included in this survey. Two studies investigated inguinal hernia repair, six laparoscopic cholecystectomy, five gynecologic procedures, two laparoscopic suturing, and two camera navigation during laparoscopic procedures. Simulation-trained participants showed superiority in surgical performance in comparison with untrained surgeons. The operation time, accuracy, incidence of intraoperative errors, and postoperative complications were statistically better in the simulation-trained group in comparison with the conventional-trained group. Conclusion. Simulation provides a safe, effective, and ethical way for residents to acquire surgical skills before entering the operating room.
