Crowd Evacuation

The simulation of a crowd evacuating public buildings can be an important reference in planning the layout of buildings and formulating evacuation strategies. This paper proposes an agent-based crowd model; a crowd evacuation navigation simulation model is proposed for the multi-obstacle environment. We introduce the concept of navigation factor to describe the proximity of the navigation point to the exit. An algorithm for creating navigation points in multi-obstacle environment is proposed along with the global navigation and local navigation control algorithms of the crowd. We construct a crowd evacuation simulation prototype system with different simulation scenes using the scene editor. We conduct the crowd evacuation simulation experiment in the multi-obstacle scene, recording and analyzing the relevant experimental data. The simulation prototype system can be used to derive the evacuation time of the crowd and analyze the evacuation behavior of the crowd. It is expected to provide a visual deduction method for crowd management in an evacuation emergency.

The article deals with the preparation of simulation model of mechanism with parallel kinematic structure called hexapod as an electro-mechanical system in software MATLAB/Simulink. The simulation model is composed from functional blocks represented each part of mechanism’s kinematic structure with certain properties. The results should be used for further simulation of its behaviour as well as for generating of control algorithms for real functional prototype.

Rent Or Buy

The decision to rent or buy a home is probably the most important in family finance. Yet the analysis of this problem in the literature has been superfi cial and subject to many criticisms. This paper will develop a complete simulation model to investigate this decision and to look at many related questions such as the type of loan best suited to the family's financial policies, the price range that a given family can afford, and the type of other investments consistent with this decision. The model simulates the family income, expenses, and investment portfolio on a monthly basis over the planning period. The results are compared to a deterministic analysis based on a capital budgeting model of the family. Finally, a case study based on data obtained from a real family will be present ed. Further use of the simulation model to study many other capital budgeting problems associated with family finance will also be discussed.

Undulating Fin

Current methods of unmanned underwater locomotion do not meet stealth, robustness and efficiency. This work discuses about designing a Bioinspired UUV or Unmanned Underwater Vehicle that uses an undulating fin approximating to that of a cuttlefish fin locomotion. This propulsion method has higher maneuverability and ability to navigate while leaving its surroundings relatively undisturbed as compared to other propeller based systems. Mathematical models and control algorithms describing the complicated locomotion have been developed, and a simulation model is used to verify the theoretical results. This design of UUV can be utilized for underwater data collection and military applications without hampering the underwater wildlife.

Electric Bus

Introduction (problem statement and relevance). Currently, one of the main and promising directions in the automotive industry is the development of the electric vehicle and charging infrastructure sector. The constant tightening of environmental requirements, the development of traction batteries (TAB) and automotive electronics are the main factors in the development of wheeled electric vehicles. The operation of electric buses on urban routes in modern cities is one of the promising developments of electric buses use. But the problem is, the TAB capacity, its resource and cost are still limited, therefore a key task in the development of an electric vehicles the choice of the most effective control algorithms and components of the traction electric drive (TED). The solution to this problem requires working out a simulation model, the accuracy and complexity of which must satisfy the chosen goal.The purpose of the study was to develop and verify a KAMAZ 6282 electric bus simulation model basing on experimental data.Methodology and research methods. The article presents an experimental and calculated data analysis of the main electric bus movement modes when driving in a city: acceleration, coasting, braking, upward movement.Scientific novelty and results. Basing on comparing the experimental and calculated data results, it has been determined that the presented simulation model of the electric bus was sufficient and adequate to determine the main performance indicators of the TED.Practical significance. The presented simulation model made it possible to analyze the performance indicators, on the basis of which the selection of the optimal TED components could be carried out. The simplicity of the simulation model allowed it to be used as part of optimal control algorithms and evaluate the electric bus movement along a city route.

Plant Modelling

This paper describes the application of a computer-aided control system design (CACSD) tool known as Simulink. Simulink is a modern non-linear dynamic simulation tool and forms an extension to Matlab,* adding many features specific to dynamic systems. The application of Simulink to a water treatment works pumping station is outlined. The objective is to enable a complex simulation model of the plant (block diagram descriptions), including all relevant process dynamics, to be easily built up. Using this simulation model a control strategy is designed to maintain the water level in a two well sump within a specified operating band. The level constraint has to be met irrespective of inflow transients due to filter washes, surges, etc. Having designed the controller based upon plant model simulations, the control algorithms were coded in the programmable logic controller (PLC) to be used on the plant. The PLC was interfaced to the plant model in real time to validate the performance of the controller against the simulated plant. The application of Simulink for plant modelling and analysis proved to be successful in that a controller was easily designed and implemented, and exceeded the performance specifications.
