Modelling of a solar project network for time improvement

Sammanfattning: This thesis is written for the Finnish company Wärtsilä and looks into the project processes of an EPC solar project and an EPC Engine power plant project to find similarities, by looking into both qualitative and quantitative aspects. This is done so that Wärtsilä may use the information gained from the engine power plant projects to further their solar projects by cutting down the total project time. These comparisons are done by collecting data from interviews and from constructing a project network for both projects, which is then remade into a linear program, solved, and then evaluated by sensitivity analysis and looking into the critical paths and slack times of both networks. This data is then used to present a recommendation to Wärtsilä on which activities should be prioritised when trying to improve the project time. These recommendations include looking into container usage, the installation process of posts and photovoltaic panels, as well as allocation of manpower for civil work.
