Determination of spool fabrication priority in industrial piping using simple weighted sum

With considering the accessibility limitation of industrial units piping and with the aim of accelerating pipes installation, spool pre-fabrication perform a process. As a simple definition, the spool is a complex of parts and the related joints. Spools priorities determination in the piping process is one of the most important stages of the project. On the other hand, using the complicated sequencing models, since their effortful and time-consuming nature, make solving the problem so difficult. Therefore, providing a decision-making approach to increase accuracy and comprehensiveness is necessary. In this paper, we used the simple weighted sum and complex proportional assessment method as the simple, understandable and fast decision-making methods in the industrial numerical example and, By the way, we reviewed and introduced the important priorities in spool pre-fabrication. Finally, the obtained results and the related comparisons with the intuitive values represent reasonability and practicality.
