The aim of the article is presenting a mathematical model of the assembly process of large-size marine structures. Numerical encoding approach of essential features of the structure and welding methods is proposed. The model takes into account information about the geometry of the connections between elements and their orientation in space during the assembly process. Welding processes are characterized by positions range of their application. The assembly process is shown as a matrix form. Assembly planning is based on the allocation of welding processes into stages and the selection of welding method and assembly position for each stage. It is shown that a lot of such plans can be generated and many of them are unacceptable. Space of feasible plans is defined by set of constraints. These conditions verify that the assembly plan performs a task of welding of all joints and whether it is feasible for particular methods. The methods for calculating the impact of all conditions . an accurate deterministic and randomized approximate are proposed. It is shown that assumed conditions dramatically reduce the set of assembly plans. Moreover, the method of including additional conditions into the model according to the connections making sequence is presented. Sample calculations are shown in two examples . first that is extremely simplified, allowing for a full deterministic analysis of the problem, and a second that is more complex, requiring a partial approximate approach. The article indicates the possibility of using the optimization of the assembly plan. Furthermore, the set of applicable criteria is proposed.(original abstract)
