| Abstract | This paper proposed a scenario manager capable of creating and editing shipbuilding production processes for multibody dynamics-based simulation. The proposed scenario manager was composed of three components: Actor, Scenario Executor, and Integrator. Actor represents a minimum unit of action in multibody dynamics kernel and it can be connected with specific component of dynamics kernel such as body, joint, wire, and so on. A shipbuilding production process can be made by combining these actors sequentially and in parallel. Including these combination of actors, Action List contains information for executing actors. Scenario Executor has this action list, and executes actors according to the execution order in the action list. Since the process of shipbuilding production is a kind of event-based sequence, all components of the scenario manager were configured using DEVS (discrete event system specification) formalism. To verify the effectiveness of the proposed scenario generator, it was applied to various shipbuilding production simulation such as lifting and erection of a block, heavy load lifting operation using multi-crane, and launching operation of an icebreaker using two floating cranes. |
