The present paper proposes an analytical approach to optimise the transfer project of industrial plants, already installed and functioning, in a new productive location. From the operational point of view, to transfer a plant means to transport in a new site the same functional characteristics the plant has in the original one. Given the frequent impracticality to move the plant as formerly installed, the problem is, then, to define a valid transferring project, which should take into consideration the constraints and opportunities related to the execution of two strongly specular phases. The proposed approach is based on an algorithmic procedure which, once selected the main components of a plant according to typical criteria of the process flow analysis, is able to determine and optimise the transfer global cost, as function of the parameters characterising the three different project phases; disassembling, transporting and local reassembling of the plant. The core of the procedure is constituted by an iterative structure which, starting from an analytical description of the plant, in terms of components and modalities of breaking down, integrates the loading and transport phases and estimates, at the same time, the best level of reduction of the plant, the relative disassembly sequences and the loading efficiency. Those evaluations allow to optimise the overall cost of the three project phases.

Abstract
The present paper proposes an analytical approach to optimise the transfer project of industrial plants, already installed and functioning, in a new productive location. From the operational point of view, to transfer a plant means to transport in a new site the same functional characteristics the plant has in the original one. Given the frequent impracticality to move the plant as formerly installed, the problem is, then, to define a valid transferring project, which should take into consideration the constraints and opportunities related to the execution of two strongly specular phases. The proposed approach is based on an algorithmic procedure which, once selected the main components of a plant according to typical criteria of the process flow analysis, is able to determine and optimise the transfer global cost, as function of the parameters characterising the three different project phases; disassembling, transporting and local reassembling of the plant. The core of the procedure is constituted by an iterative structure which, starting from an analytical description of the plant, in terms of components and modalities of breaking down, integrates the loading and transport phases and estimates, at the same time, the best level of reduction of the plant, the relative disassembly sequences and the loading efficiency. Those evaluations allow to optimise the overall cost of the three project phases.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
