“…From among analysed methods, four methods have outstanding results which are, consecutively, methods: [14], [19], [20] and [21]. However, the work [14] is not dedicated to hull assembly, consequently its implementation in this area would be very time and effort consuming.…”

“…The method described in [21] consists of two parts: -Hierarchical clustering of assembly unit parts. It makes use of the so-called rule-based expert system and can be used for dividing the structure into subassemblies, with further creation of assembly sequence, -Optimisation of clustering diversification degree.…”

“…The proposed method of hierarchical clustering requires defining the fuzzy similarity relationship u i,j ∈[0,1] for each pair (i,j) of structure parts. The rules to assess the quantities u i,j are defined in [21]. They are determined by an expert and their use is somewhat problematic, as the expert is expected to plan partially the assembly before assigning the value of u i,j .…”

“…Thus, this method, on the one hand, makes it possible to divide the structure into subassemblies, but on the other hand, it requires from the expert to define a priori this division. The authors of [21] also propose common consideration of identical parts which are to be assembled simultaneously or directly after each other. This refers, for instance, to parallel ribs.…”

The article characterises the sea-going vessel hull assembly processes and then reviews the existing assembly methods of mechanisms and welded ship structures. Classification of these methods is done with respect to selected criteria of their applicability to hull assembly. Selected methods are used for calculations performed on a model structure and exemplary database. The analysed aspects include the performance of calculation algorithms and the quality of the obtained solutions. Particular attention is paid to the need for reduction of experts’ participation in the planning process due to strong search space explosion effect. The performed analyses have enabled the authors to formulate assumptions for models which would be applicable in real assembly planning in shipyards, as well as to indicate areas of further research which would make it possible to better consider the specificity of production of large-size welded structures.

The specificity of the yard work requires the particularly careful treatment of the issues of scheduling and budgeting in the production planning processes. The article presents the method of analysis of the assembly sequence taking into account the duration of individual activities and the demand for resources. A method of the critical path and resource budgeting were used. Modelling of the assembly was performed using the acyclic graphs. It has been shown that the assembly sequences can have very different feasible budget regions. The proposed model is applied to the assembly processes of large-scale welded structures, including the hulls of ships. The presented computational examples have a simulation character. They show the usefulness of the model and the possibility to use it in a variety of analyses.
