Simulation between tool and automatic tool construction operations

Abstract EN

Construction operations range from manual (tool) to automation (automatic tool) operations, which are difficult to analyze and optimize using standard mathematical methods.

Simulation is an alternative method of analysis that offers numerous benefits.

Simulation technique proves its capability of assessing productivity of any construction operation that has repetitive nature.

To design construction operations it is necessary to make decisions, including determination of crew size, selecting equipment, establishing operating logic, and selecting construction method.

This paper presents the effectiveness of applying Micro CYCLONE version 2.7 as a simulation engine in productivity improvements.

Different repetitive construction operations are selected as follows : •Mini tunnelling by TBM as automatic tool operation.

•Micro tunnelling by pipe jacking and mechanical plastering as power tool operations.

•Manual plastering as tool operation.

The simulation models of these operations were designed and validated according to actual crew design until reaching the best-fit simulation models.

Change the simulation model resources to get the optimum one, which produce maximum productivity, minimum cycle time, and minimum cost.

Sensitivity analysis was applied to the result of simulation.

the productivity improvements result increases in manual operations and decreases by applying automation in the construction operation and these improvements range from 22.75 % to 1.68%.
