Analytical Approach to a Two-Stage Queueing Network for the Planning of Outfitting Processes in Shipbuilding Available to Purchase

As an important part of shipbuilding, outfitting can represent a major portion of the material cost as well as the construction time of a vessel. However, due to disturbances caused by unexpected delays, system variations, and technological constraints, scheduling of outfitting processes is therefore complex and can lead to major construction delays. To improve the shipbuilding system efficiency in the presence of variation, a two-stage strategic level outfitting planning model has been developed. The results of the model provide the optimal percentage of outfitting work that should be completed at each stage given the introduction of variation. The model presented can be used as a benchmark for current ship outfitting management decisions.
