Railroads move freight traffic on their network based on an overall operations plan that includes blocking, train formation, and train scheduling plans. The optimization of these operations over the entire network is integral to maximizing efficiency and minimizing costs. This thesis develops a simulation model for analyzing various operation plans of a railroad network along with guidelines for establishing a comprehensive operations plan. The objective is to move all freight on the network with minimal cost. With the model simulation and comparison of several operation plans can be performed to determine the 'best case' plan. The model implements a discrete state, deterministic simulation approach. The user-friendly software for implementation of the model was programmed in VBA and Excel. Application of the model is demonstrated using a hypothetical railroad network. The results show that the model is an effective tool in evaluating various scenarios and helping in determining the best plan.

Scene simulation technique has been widely used on the field of weapon developing. However, the problems such as technique intricacy and the difficulty of cooperating with work prevent it further developing. So the scene simulation approach to the complex system is put forward based on UML. It can be used to manage effectively the relation of scene simulation models with UML, the organization of models, and the maintenance or the modification of the simulation, to implement till the optimized project. Practical application showed that the approach is available for visualization of numerical calculation, simulation model, simulation interaction, maintenance and modification of scene simulation. It can improve actual operation efficiency considerable.

Abstract A realistic computerized simulation of double-bar plush fabrics can result in a time-saving development process with high quality. Based on basic analysis of jacquard principles, a fast 3-D simulation method of warp-knitted plush fabrics is proposed by using a geometry shader on GPU. Firstly, pile areas and non-pile areas are identified according to the jacquard design graphs and chain notations. According to the directions of observation and raised pile, two layered chips are formed in the geometry shader with an approach of multi-layered textures. To ensure that the simulated piles resemble the real ones, the directions of the piles are randomized with the Perlin noise method. One pile is generated along its length with numerous layers in the plush fabric model. Simulation results of piles on both the technical face and technical back are obtained via the model built above, which is confirmed with practicability and efficiency. This 3D simulation approach improves the visualization appearance of piles just as they are actually raised.

Bangladesh, India and Sri Lanka are three important South Asian economies that lie in the Bay of Bengal and the Andaman Sea (BoBAS) rim region. Considering intra-regional trade, these countries are loosely economically integrated, although they have a large potential for sub-regional trade grains. This study examines the determinants and potential of intra-regional trade among these countries. In the beginning, the study estimated the gravity model of trade with a panel random effects estimation for a set of data from 1991 to 2012. Later it investigated trade potential among the countries by a simulation approach that is based on the prior findings of the gravity estimation. The results show that major determinants of intra-regional trade in these countries are size of the domestic market, infrastructure, economic openness, real exchange rate and distance. Countries in the sub-region have high trade prospects and they have not explored the maximum potential of intra-regional trade yet.
