مدیریت ساخت و ساز تکراری در یک محیط پروژه در حال تغییر در دینامیک: مفهوم سازی مدل سیستم سیسکو نکسوس

This paper presents a methodology for modeling repetitive construction projects by introducing a modeling procedure based on the system–model–simulator nexus, with the aim of developing an intelligent tool to facilitate decision-making in the construction implementation phase. The study offers a conceptualization of the construction processes designed for the monolithic construction computer-aided system (MoCCAS) that enables a flexible approach to managing repetitive projects within a dynamically changing construction environment. The discussion deals with the art of modeling the construction process and introduces a repetitive construction process formulated as (1) a dynamic construction process model in a temporal perspective (DCPM-TP), which is a construction process representation in a three coordinate system; and (2) a managing assumed goals (mag_811) module, designed to simulate process behavior and to create execution strategies. Both models are capable of handling variability during the construction process execution and address the complexity of the relations among the production system components, including resource mutual constraints. A case study is discussed which involves the execution of construction processes by means of a slip formwork system, which exhibits a large degree of repetition and, therefore, is a particularly useful example for illustrating the effectiveness of the modeling approach proposed. The original contribution of this research lies in (i) representing construction process by acknowledging the specificity deriving from the nature of repetitive projects and technological regime; (ii) developing flexible structures (DCPM-TP and mag_811) that enable the construction process complexity to be addressed; (iii) designing a representation of the construction process within the system–model–simulator nexus developed for MoCCAS. A significant outcome of the overall study is the development of a system capable of harnessing the cyclic nature of the repetitive processes and converting the repetitiveness into a vital asset in the construction management.
