A heuristic procedure for determining the tradeoff between expediting the ordering of materials and delaying the project is presented. The heuristic procedure is a modification of the procedure taken from the literature. With the use of an illustrative example, it has been shown that the modified procedure provides schedules with lower total cost values. Experimental results performed on randomly generated problems reveal that the modification can bring a decrease in total cost values as much as 52%.

A genetic algorithm for the resource constrained project scheduling problem
Özleyen, Erdem; Sönmez, Rifat; Department of Civil Engineering (2011)
The resource-constrained project scheduling problem (RCPSP) aims to find a schedule of minimum makespan by starting each activity such that resource constraints and precedence constraints are respected. However, as the problem is NP-hard (Non-Deterministic Polynomial-Time Hard) in the strong sense, the performance of exact procedures is limited and can only solve small-sized project networks. In this study a genetic algorithm is proposed for the RCPSP. The proposed genetic algorithm (GA) aims to find near-o...
A genetic algorithm for resource leveling of construction projects
Iranagh, Mahdi Abbasi; Sönmez, Rifat (2012-01-01)
Critical path method (CPM) is commonly used in scheduling of construction projects. However, CPM only considers the precedence relations between the activities and does not consider resource optimization during scheduling of projects. Optimal allocation of resources can be achieved by resource levelling. Resource levelling is crucial for effective use of construction resources particularly to minimize the project costs. However, commercial scheduling software has very limited capabilities for solving the re...
An exploratory study on utilization of BIM for risk management
Kaya, Hazal Deniz; Dikmen, İrem; Atasoy, Güzide; Birgönül, Mustafa Talat (İstanbul Teknik Üniversitesi; 2020-11-14)
It is a well-known fact that BIM application in construction projects enables several advantages such as better collaboration and communication, effective project visualization before construction, more efficient cost estimation and scheduling, and an increase in productivity. Although many of these advantages that BIM contributes to construction projects may result in opportunities for better risk management, there are limited studies in the construction management literature that investigate this subject....
A method for decentralized business process modeling
Türetken, Oktay; Demirörs, Onur; Department of Information Systems (2007)
This thesis study proposes a method for organizations to perform business process modeling in a decentralized and concurrent manner. The Plural method is based on the idea that organizations’ processes can be modeled by individuals actually performing the processes. Instead of having a central and devoted group of people to understand, analyze, model and improve processes, individuals are held responsible to model and improve their own processes concurrently. These individual models are then integrated to f...
A decision-support tool for risk and complexity assessment and visualization in construction projects
Dikmen Toker, İrem; Atasoy Özcan, Güzide; EROL, HACI HÜSEYİN; Kaya, Hazal Deniz; Birgönül, Mustafa Talat (2022-10-01)
© 2022 Elsevier B.V.Risk assessment in projects requires the integration of various information on project characteristics as well as external and internal sources of uncertainty and is based on assumptions about future and project vulnerability. Complexity is a major source of uncertainty that decreases the predictability of project outputs. In this research, the aim was to develop a decision-support tool that can estimate the level of risk and required contingency in a project by assessment of complexity ...
