Modern Experience

Simulation is the main way for testing technologies in the field of multi-hop wireless networks (MWN). Creating a simulation model MWN - a time-consuming task associated with the use of specialized software tools, called network simulators. In this paper, the modern experience of modeling MWN and the main problems are formulated. One of the main problem is the comparative analysis' impossibility of the experiments results conducted by various researchers. This is due to the reasons associated with the models used for testing, the planning an imitation experiment and the principal differences in the network simulators. To solve this problem, authors propose a generalized conceptual model of MWN simulation and a specialized software package that automates the execution of experiment series in a heterogeneous modeling environment.

Freight Flow

This paper develops a simulation model to include the short-sea shipping (SSS) on the intermodal freight flow model the author already developed, in order to measure an impact of policy that encourages the utilization of the SSS. The developed model is applied to the real shipping network connecting the northern Kyushu area in Japan with China and Korea; as a result, the model reproduces the actual maritime shipping market well, and some implications are acquired such that in order to advance utilization of the SSS, a kind of drastic policy such as mutual recognition of chassis is needed.

One way to increase the productivity of artificial forestation is to control the density and relative position of trees. In this regard, there are tasks of finding the optimal planting schemes to obtain the maximum wood stock of a given diameter. Based on the developed simulation model, a comparative analysis of the productivity of spruce stands with different planting schemes was carried out. The optimal forest planting schemes for spruce stands, which provide the maximum stock of small, medium and large wood, are determined. It is shown that in order to maximize the stock of wood of different size classes, different initial planting densities are required. The higher the size classes of the grown wood, the lower the optimal planting density.

In this paper, a new methodology for integrated modelling of the WWTP has been used for the construction of the Benchmark Simulation Model N°2 (BSM2). The transformations-approach proposed in this methodology does not require the development of specific transformers to interface unit process models and allows the construction of tailored models for a particular WWTP guaranteeing the mass and charge continuity for the whole model. The BSM2 PWM constructed as case study, is evaluated by means of simulations under different scenarios and its validity in reproducing water and sludge lines in WWTP is demonstrated. Furthermore the advantages that this methodology presents compared to other approaches for integrated modelling are verified in terms of flexibility and coherence.
