Ship and submarine production and repair have benefited significantly from more intelligently allocating resources and managing other constraints, thereby increasing efficiency, and reducing overall project duration. In complex production and repair environments, such as ship production/repair, the method of allocating resources and managing other constraints significantly affects the efficiency of progress and thus the overall project duration. Resources include human resources, equipment resources and physical-space resources. Due to the inherent complexity of resource allocation and constraint management for such complex environments, the project durations can be 25%+ longer than necessary. This paper shares the real-world results experienced by the authors as well as similar results found in the literature showing the major difference in project duration due to resource-scheduling techniques.
