Objective: Assessment of the need to study the process of delivering a batch of containers from the rear terminal to the port to ensure uninterrupted communication between the rear terminal and the seaport and delivery a batch of containers exactly on time. As a primary task, the problem of analyzing the factors affecting the nature of the delivery process is solved. Methods: The methods of the theory of probability and mathematical statistics were applied in terms of determining the factors that affect the nature of the delivery process. The method of constructing process models was used to create a technological model for the delivery of containers by a block train to the port. Results: A technological model of container delivery by block train is presented. Diagrams were built showing the share of the main deviations from the schedule of container trains by types of operations for traffic, traction, corporate transport services. The main factors influencing the duration of individual operations with container block trains en route and the increase in the delivery time for a batch of containers from rear terminals to the seaport as a whole are identified. The random nature of the duration of the delivery of containers by block trains following the schedule has been established. Practical importance: The need to improve the methodology for choosing a method for delivering containers from the rear terminal to the port using simulation based on the identified factors influencing individual elements of the technological model of container delivery by a block train, deviations from the delivery time of containers, scheduled running of block trains is shown.

Although simulation has become a very important aspect in product development today, a study of current design methodologies by Dohr and Vielhaber has shown that there is currently no methodology fully incorporating simulation within the context of mechatronic product development. The results of this study are used to derive specific needs of a simulation-based design process. Based on these requirements a process model for simulation-based mechatronic design is developed which is based on process steps of established design methodologies. In order to integrate simulation, the process model consists of two activity streams: analysis activities are linked to the specific design activities of mechatronic systems. Based on these two streams guidance is provided on which simulation technique should be used for specific activities and how the results from the simulation have to be handled in order to improve design without macro-iterations. With regard to mechatronic interdisciplinarity as well as data and model management, the use of a system model as a platform for the exchange of information and knowledge is integrated into the process model. Finally an outlook on future work regarding the detailing of the process model as well as on the application of the process model is provided.

In this study, an integrated coastal process model was applied to assess impact of coastal flooding and sedimentation in an estuary in Taiwan and to evaluate performance of proposed engineering plans for flood prevention and sedimentation management. This in-situ validated model was used to simulate and predict hydrodynamic processes and morphological changes induced by multiple hydrological forcing such as river flood flows, waves, tides, and storms surges from rivers to the estuary and its adjacent coasts. Simulation results quantified coastal flooding risks, erosions, sedimentation, and channel refilling. Predicted dynamic responses to typhoons and monsoons were utilized for identifying the most effective engineering plan to reshape the geometry of the estuary. After the selected engineering plan was accomplished, this model was applied again to further predict morphological changes in the newly-developed estuary. This paper demonstrates effectiveness of a simulation-based coastal and estuary planning approach to manage flood and sedimentation driven by complex physical processes from river flows, waves, tides, and sediment transport.

Functional design is the essential process of product design. Aiming at the drawbacks of traditional functional design, effect in TRIZ is introduced for function modeling, solving and simulation. The improved process model of functional design is proposed, and the computer-aided functional design software system is developed. Finally, the speedy cutting off valve is taken as an example to validate the effectiveness of the above model.
