Tiivistelmä
The focus of this thesis is on development of layout and material flow plan specifically for shipyard operations. It appears that the available literature on this topic is rather limited and is missing direct shipyard layout planning instructions. The need for this thesis project is caused by the reduction of land and premises of the case shipyard and the need for updated layout plan, which in perspective would also enhance the efficiency of intralogistics and sufficiently facilitate the shipbuilding process of planned projects. Since the changes in core facilities setting are not affecting the core production process, the development project tis focused on optimization of allocation of storage areas.
The study was conducted based applied action and quantitative research and is performed in three rounds of data gathering. First of all, the first set of data was gathered during the current state analysis and examined the weak and strong points of logistics processes, current layout and material flow routing. Most importantly, the current state analysis included gathering of planned production data for further layout planning purposes, as the conceptual framework was built based on the type of available data.
The theoretical part of this thesis studies the existing practices of shipyard layout planning and material flow optimization in combination with similar practices in heavy industry, which are possible to be applied to highly constrained and regulated environment of shipbuilding.
The second set of data was gathered during development stage of this thesis and is represented by the set of improvement suggestion from the case company procurement and logistics management representatives in order to complete building of initial layout and material flow routing proposal. The last set of data was gathered at the project validation stage, and is represented by the set of final correction and improvement suggestion for the final proposal.
The layout plan is developed using the systematic layout planning approach in combination with metaheuristic shipyard facility layout planning techniques. The material flow routing optimization is performed in accordance with Intelligent Water Drop algorithm in combination with shipyard material distribution optimization approach. Both optimization procedures are performed using Python programming and results are generalised into comprehensive format to be applied as a part of operating instructions for logistics workforce of the case company. Additionally, a list of further improvement suggestions is generated in order to maximize the positive of proposed layout and material flow changes. The proposed layout and material flow plan minimize aim at minimizing the travel distances and maximizing the set of closeness importance factors for each of the links between the storage areas and shipyard’s core facilities.
