A network planning model for offshore structures

Stochastic models can be used efficiently in order to model the Stochastic models can be used efficiently in uncertainties in the activity cost and schedules of the offshore platform have some disadvantages. For example, construction projects. However, they have some disadvantages. For example, the Program Evaluation and Review Technique (PERT) which is a Level 2 model, will introduce additional bias problems in the estimation of the activity duration. Level 3 stochastic models (e.g. Monte Carlo simulation), which are developed to avoid the bias problems of the PERT require lost of computational efforts. In this study, the available stochastic models used in the determination of the optimum time and cost trade-off of the offshore construction projects are compared with respect to their efficiencies. Monte Carlo simulations of the network are performed and a network planning model is suggested. These models are applied to Gulf of Mexico offshore platform (Bullwinkle) project
