One of the challenges related to the design of arctic cargo ships is that their transport capacity is dependent on a number of arctic specific design parameters (e.g., ice conditions and the availability of icebreaker support) in which there typically is a significant level of uncertainty and stochasticity. This paper addresses that challenge by presenting a design method that deals with the parameter uncertainty by integrating method of risk assessment in to the design process, i.e., by utilising the principles of Risk-Based Design (RBD). In order to obtain a holistic approach, the design method treats a ship as an arctic sea transport system that might include multiple ships, icebreakers, and port-based facilities such as cargo storages. Using the method it is possible to design an arctic sea transport system that provides a desired level of operational reliability. This provides the means to minimise costs and financial losses due to over- or undercapacity, and thereby to improve the resource-efficiency of the system as a whole.

The Right

A loading/unloading mechanism was designed using the axiomatic design method. The mechanism is a standardized part of a smart factory currently implemented at Fraunhofer Italia research institute on behalf of the DeConPro research project, and as such is specified to fit any processing station. The mechanism is used in conjunction with an automated transport system, which carries standardized transport boxes on rails. The transport systems stop at the processing stations and shall be grabbed by the mechanism subject of this publication and dragged into the processing station, where. Also, the transport boxes must be fixed onto the shuttles of the transport system avoiding drops while moving, which is also part of the design exercise. Inside the processing station, the transport boxes shall be further movable in both directions perpendicular to the direction of the mechanism movement. The mechanism shall build compact especially in depth, and shall also be optimised in cost, as it is a recurring item in all processing stations. The resulting FR/DP decomposition lead to an decoupled design matrix up to second level, which allowed for choosing the right engineering sequence of the functions. The axiomatic design procedure helped considerably in finding the best concept for holding and handling the box. The further engineering steps benefit also considerably by the anticipated trade-off between alternatives for actuator types.

The escape performance of ejection seat under adverse attitudes is the key technology for the 4th generation ejection seat, and the design of control law algorithm is the core problem for attitude and trajectory adjustment. A new control law design method was presented. Firstly, a simulation model for the entire ejecting process was established and a control parameter optimization model was designed, through which an optimum parameter set was obtained as the discrete control law. Then, by utilizing multilayer feedback of the error back propagation (BP) algorithm based neural network model, the ultimate continuous control law can be acquired under the whole ejecting conditions. The roll attitude ejecting condition was exampled to design and validate the approached method. The results indicate that the performance of ejection seat by adopting the control law designed by the proposed method is higher than the multi-mode control law and the K3JI-3.5 ejection.
