摘要

如今,各组织和公司都充分认识到,考虑到客户需求和口味的快速变化,他们无法满足客户的需求。此外,各组织为增加产品种类和提高自身地位所做的努力似乎也不足以满足客户的需求。各组织和公司相互利用对方的专业知识和设施,以连贯高效的供应链形式满足客户的需求,这是技术不断发展的必然结果。因此,本研究采用了 "机会约束编程"(Chance-Constrained Programming)方法来弥补建设项目中的不确定性。因此,在确定与不确定性相关的参数后,这些参数将被纳入优化模型中。本研究提供的数学模型是多目标和多模式的。换言之,任何活动都假设了不同的模式和条件。此外,数学模型假设的目标之一是最大限度地减少项目实施过程中的最大延迟时间。然后,使用 GAMS 软件求解中小型数学模型,使用 Matlab 和 NSGA-II 元启发式算法求解大型数学模型。

Presenting a mathematical model for reduction of delays in construction projects considering quality management criteria in uncertainty conditions
Nowadays, organizations and corporations are fully aware of the fact that they can't satisfy their customers' needs considering the rapid change of their needs and tastes. In addition, the attempts made by organizations to add variety to their products and improving their own status don’t seem to be sufficient to meet customers' needs. Orientation of organizations and corporations to benefit from each other's expertise and facilities for satisfaction of customers'' needs in the form of a coherent and efficient supply chain was a strategy which has been the mere result of increasing technology growth. Therefore, Chance-Constrained Programming approach has been used in this study to compensate for the uncertainties resulting from construction projects. Therefore, after defining uncertainty-related parameters, such parameters will be included in the optimization model. The mathematical model provided in this study was multi-objective and multi-modal. In other words, different modes and conditions have been assumed for any activity. Moreover, one of the objectives assumed for mathematical model was to minimize the maximum delay time in project implementation. Then, GAMS software has been used to solve the mathematical model in small and medium scale and Matlab and NSGA-II meta-heuristic algorithm have been used to solve the model in large scale.

期刊介绍: Journal of Engineering Research (JER) is a international, peer reviewed journal which publishes full length original research papers, reviews, case studies related to all areas of Engineering such as: Civil, Mechanical, Industrial, Electrical, Computer, Chemical, Petroleum, Aerospace, Architectural, Biomedical, Coastal, Environmental, Marine & Ocean, Metallurgical & Materials, software, Surveying, Systems and Manufacturing Engineering. In particular, JER focuses on innovative approaches and methods that contribute to solving the environmental and manufacturing problems, which exist primarily in the Arabian Gulf region and the Middle East countries. Kuwait University used to publish the Journal "Kuwait Journal of Science and Engineering" (ISSN: 1024-8684), which included Science and Engineering articles since 1974. In 2011 the decision was taken to split KJSE into two independent Journals - "Journal of Engineering Research "(JER) and "Kuwait Journal of Science" (KJS).
