Employee turnover is a major problem for many companies because it brings with new issues including hiring costs, overtime costs, low productivity. Hence, preventing or reducing turnovers is a challenging task in human resource management field. At this point, employee turnover prediction plays an important role in providing early information for highly probable turnovers in near future that enables companies to take precautions against this situation. In this thesis, we work on this problem to predict whether an employee will leave his/her company within a certain time period. We formulate this binary classification problem as a supervised machine learning problem. Our study exploits publicly available employee profiles taken from the Web and job transition graphs extracted from these profiles. Main contribution of our study on predicting turnovers is the forming and use of job transitions of employees as well as the publicly available information about employees and institutions. So far, most of the turnover prediction models are built with the statistical methods or data analysis techniques and they make use of detailed employee information like age, race, job performance in company or job satisfaction survey results. To the best of our knowledge, this is the first study on predicting turnovers using job transitions and machine learning methods. With the help of job transition graph analysis and relevant features extracted from the graphs, many machine learning models under the change of year and time period parameters are composed. Several experiments with several models on different years’ employee profiles indicate that our proposed models have considerably predictive capabilities compared to different baselines.

Operating a successful business within the construction industry has become more difficult for companies as the profitability margins decreased considerably compared to previous years. Even, global economy has created an environment in which construction firms are enforced to bid projects at or below lowest profit levels. At the same time, owners are demanding more difficult projects without increasing the quality of contract documents. This has placed an added burden on the individual contractor to constru...
Development of a decision support system for employee scheduling problem in hospitality sector: a case study in a Turkish firm
Ünsal, Emre Ber; Karakaya, Gülşah; Department of Business Administration (2019)
Employee scheduling problems arise in many environments where a group of employees works together. This study deals with the employee scheduling problem in hospitality sector where the employees are supposed to greet and communicate with the guests in the events. The content of the problem is assigning different skilled employees to the events which have different complexity and difficulty levels. We propose a solution method which aims to create better employee schedules in terms of cost and quality of the...
Job shop scheduling using fuzzy logic
Bilkay, O; Anlagan, O; Kilic, SE (Springer Science and Business Media LLC, 2004-04-01)
In a flexible manufacturing system (FMS) scheduling problems become extremely complex, even for simple breakdowns, when dynamic uncertainties such as machine breakdowns and the uncertain arrival of jobs are taken into consideration. In the first stage of this study, a fuzzy logic-based algorithm for assigning priorities to part types that are to be machined is proposed. In the second stage, an operation-machine allocation and scheduling algorithm is presented. A criteria contribution equalizer is used in de...

Developing a roadmap for knowledge management in construction industry
Erkan, Ceyhun Selim; Nielsen, Yasemin; Department of Civil Engineering (2007)
High turnover rate of employees in construction cause companies in the sector struggle against knowledge loss. Due to the high competition in the market, companies differentiate by keeping and increasing their intellectual capital generally acknowledged as the main source of competitive advantage. Knowledge Management (KM) is defined as any process or practice of creating, acquiring, capturing, sharing, and using knowledge, wherever it resides, to increase learning and performance by sustaining organisation...
