Abstract

Nowadays, the problem of scheduling and executing projects with the least cost and time has become one of the main concerns of project managers. In this regard, researchers have used different methods and patterns. One of these methods is to use concurrent engineering in projects. Simultaneous engineering means the creation of a project schedule for projects based on existing units and human resources so that a synchronous rule can be applied to the project so that the project can be completed in less time. Modeling time and cost in large-scale construction projects is actually complicated and complicated. These complexities actually increase the risk of time and cost in the project. In this research, a new method called Chouquet integral algorithm is used to analyze time and cost equations. The Chouquet integral is a method used to analyze and linearize complex equations. The proposed method is implemented on an executable model in 2017 and analyzed and analyzed in MATLAB software. The results show that the error rate of time and cost in the construction model resulted in a reduction of 27 and 14%, respectively. Commonly, the structure developments will take an extended period to broad. In this background approximating structure costs are main stages for plan estimators, independents. The evaluating procedure is a stimulating occupation owing to variations in building features and that trend rising over the extended period. The movement time-cost association has for the most portion been presumed to be lined, but, a rare revisions have recommended that this is not essentially the situation in exercise. These prototypes carefully represent the most public circumstances happening throughout construction developments. The benefits of these models are that they tolerate for together separate and constant, in addition to deterministic outlines. Moreover, the amount of possessions needed for deafening the movement can be measured. Contrasts amongst the models and additional new fast-following model from the procedure are debated and a Chouquet integral algorithm is applied for a fictional usage instance including together density methods.

利用线性Chouquet积分算法设计大型建设项目的最优时间成本模型
如今,如何以最少的成本和时间安排和执行项目已成为项目经理关注的主要问题之一。在这方面,研究人员使用了不同的方法和模式。其中一种方法是在项目中使用并发工程。同步工程意味着为基于现有单位和人力资源的项目创建一个项目时间表,以便同步规则可以应用于项目,以便在更短的时间内完成项目。大型建设项目的建模时间和成本实际上是复杂而复杂的。这些复杂性实际上增加了项目中的时间和成本风险。在本研究中,采用了一种名为Chouquet积分算法的新方法来分析时间和成本方程。Chouquet积分是一种用于分析和线性化复杂方程的方法。该方法于2017年在一个可执行模型上实现,并在MATLAB软件中进行了分析和分析。结果表明,该模型的时间和成本错误率分别降低了27%和14%。通常,结构的发展将需要一个较长的时期才能广泛。在这种背景下,估算结构成本是独立计划估算者的主要阶段。由于建筑物特征的变化和在较长时期内不断增加的趋势,评估程序是一项令人兴奋的工作。大多数情况下,运动时间-成本的关联被认为是不存在的,但是,罕见的修订建议,这并非运动中的基本情况。这些原型仔细地代表了整个建筑开发过程中发生的最公共的情况。这些模型的好处是,除了确定的轮廓外,它们还可以容忍分离和恒定的轮廓。此外,震耳欲聋的运动所需的财产的数量是可以衡量的。讨论了模型之间的对比以及该过程中附加的新的快速跟踪模型,并将Chouquet积分算法应用于包括密度方法在内的虚拟使用实例。
