Abstract
New port facilities at Punta Langosteira, on the north- west coast of Spain, involve the construction of a large rubble mound breakwater that requires thousands of concrete armour units that will have to be supplied as the construction project progresses. For that reason, a provisory plant has been built in situ where the concrete blocks are cast, transported and stacked. Due to the im- plementation of a DGPS system, the blocks life cycle can be traced and an assessment of strategies for mini- mizing the number of blocks moves became plausible. In this paper, we describe the operational analysis for the determination of a comprehensive and simple set of rules which may result in a cost-effective operation of the concrete blocks plant whilst meeting the procedural constraints. To do so, a simulation-based approach was adopted both using the commercial tool Delmia QUEST and developing our own ad hoc Java simulator.
