Construction Crew Productivity Prediction by Using Data Mining Methods

Abstract

Ceramic tiling industry has become one of Turkey's fastest growing industries due to the outstanding achievements of Turkish ceramic producers with respect to producing high quality products with lower costs than their equivalents worldwide. Conversely high costs of the end product of Turkish building industry in general show that there is an important problem with the productivity and quality of construction crews. That's why most construction firms begin to realize the need for a detailed research on the factors affecting construction crew productivity. The purpose of this study is thus to classify the factors that affect the productivity of ceramic tiling crews by using data mining methods. To achieve the purpose of our study, a systematic time study was undertaken with ceramic tiling crews in Turkey. Daily productivity values of ceramic tiling crews were collected together with the information related with the factors like the crew size, age and experience of crewmembers. Collected data was classified by using Weka program. The outlier values were first removed from the dataset and decision tree method was used to classify the new dataset. Decision tree method was preferred due to its easiness of use and rapidness in classification. Apriori algorithm, which is the mostly preferred association algorithm in previous studies, was also used to highlight the general trend in the dataset.

Breast Cancer Prediction and Detection Using Data Mining Classification Algorithms: A Comparative Study

“…Researchers who wish to conduct data mining studies can choose from a number of computer programs, some of which require payment before use, while others are free. Examination of the relevant literature [15,[24][25][26] has revealed that Weka software, a free data mining tool, is frequently used. Weka, which was developed by Waikato University in New Zealand, applies data mining algorithms using Java.…”

“…Data mining is generally used for prediction and description. There are many data mining tools such as classification, clustering, association rule mining, attribute selection and visual interactive page (Kaya et al 2014). …”

Determination and Classification of Crew Productivity with Data Mining Methods

“…Unfortunately, too many sources were not found when the literature review was conducted in this area. Kaya and his colleagues [4] tried to estimate the productivity values with the help of data obtained from the survey of ceramic workers working in construction companies. These values, which are also used as attributes in the related study, are the number of teams, the work experience and the average age of the people on the crew.…”
