On construction of stable project schedules

Görmez, Baran
It is a well-known fact that project activities are subject to considerable uncertainty, which may lead to multiple schedule disruptions during project execution. As a result, the random nature of activity durations has been the subject of numerous research efforts since the introduction of the initial PERT. A common problem which arises in project management is the fact that the planned schedule is often disrupted by several uncontrollable factors like weather conditions, other environmental factors, additional time that might be required for rework and correction of detected defects. As a result, project managers are often unable to meet the promised completion dates. It is therefore vital to take into account such possible disruptions and their potential negative consequences at the project schedule design stage. Hence, the ability of the pre-schedule to absorb disruptions may be very important in such settings. At this point two new criteria are used in modern scheduling literature: "robustness" and "stability". In this thesis, we propose several stability measures. These measures are embedded in a tabu search algorithm to generate stable schedules in a multi resource environment subject to random disruptions.


The budget constrained discrete time/cost trade-off problem in project networks
Değirmenci, Güvenç; Azizoğlu, Meral; Department of Industrial Engineering (2008)
The time/cost trade-off models in project management aim to compress the project completion time by accelerating the activity durations at an expense of additional resources. The budget problem in discrete time/cost trade-off scheduling selects the time/cost mode -among the discrete set of specified modes- for each activity so as to minimize the project completion time without exceeding the available budget. There may be alternative modes that solve the budget problem optimally, however each solution may ha...
A methodology for determining the cluster of a new project
Yiğit, Aybeniz; Saatçioğlu, Ömer; Department of Industrial Engineering (2005)
By definition, all projects are unique; however R&D projects have specific characteristics that make them harder to manage. The project management methodology applied to R&D projects may show differences due to the categorization of them. But if there exists a categorization of projects, one can analyze the properties of the project classes and then manage similar projects similarly. In this study, the R&D projects of a main military electronics company of Turkey, are analyzed. Tunç (2004) has developed a m...
Delay Risk Assessment of Repetitive Construction Projects Using Line-of-Balance Scheduling and Monte Carlo Simulation
Tokdemir, Onur Behzat; Dikmen Toker, İrem (American Society of Civil Engineers (ASCE), 2019-02-01)
Although the line-of-balance (LOB) method is widely used for the scheduling of repetitive construction projects, there are only a limited number of studies that deal with the issue of how to incorporate uncertainty in repetitive schedules. In this paper, a delay risk assessment method is proposed for projects scheduled by LOB. In the proposed method, a LOB schedule is prepared considering the target rate of delivery, and then risk scenarios are defined considering the sources of uncertainty and vulnerabilit...
An evaluation of the reinsepction decision policies for software code inspections
Nalbant, Serkan; Köksal, Gülser; Department of Industrial Engineering (2005)
This study evaluates a number of software reinspection decision policies for software code inspections with the aim of revealing their effects regarding cost, schedule and quality related objectives of a software project. Software inspection is an effective defect removal technique for software projects. After the initial inspection, a reinspection may be performed for decreasing the number of remaining defects further. Although, various reinspection decision methods are proposed in the literature, no study...
Investigating the Effectiveness of Certain Priority Rules on Resource Scheduling of Housing Estate Projects
Kanit, Recep; Gunduz, Murat; Ozkan, Omer (American Society of Civil Engineers (ASCE), 2009-07-01)
The heuristic method is one of the methods used for the scheduling of resource-constrained projects. This method is commonly used in programming the projects with high number of activities and resources such as construction investments. This paper investigates the effectiveness of three heuristic method priority rules applied in the resource scheduling of ten Turkish housing estate projects which were scheduled according to three preselected priority rules [maximum remaining path length (MRPL), latest finis...
