However, CLP model development remains a challenge, as the complex impact of multiple subjective and objective influencing variables have to be examined in various project contexts while dealing with limited data availability. On the other hand, lack of a framework for adapting existing or original models from one context to other contexts limits the possibility of reusing existing models. Such challenges are addressed in this paper through the development of a context adaptation framework. The framework is used to transfer the knowledge represented in fuzzy inference (FIS) based CLP models from one context to another, by using linear and nonlinear evolutionary based transformation of the membership functions combined with sensitivity analysis of fuzzy operators and defuzzification methods. Using four context-specific CLP models developed for concreting activity under industrial, warehouse, high-rise, and institutional building project contexts, the framework was implemented, and the prediction capability of the adapted models was evaluated based on their prediction similarity with the original models. The results showed that linearly adapted CLP models for industrial and institutional contexts and nonlinearly adapted CLP models for warehouse and high-rise contexts provide a similar prediction capability with the original models. The proposed context adaptation framework and findings from this paper address the limitations in past context adaptation research by examining a practical context-sensitive application problem and further examining the role of fuzzy operators and defuzzification methods. The findings assist researchers and industry practitioners to take full advantage of existing FIS-based models in the study of new contexts, for which data availability might be limited.<\/jats:p>","DOI":"10.1155\/2018\/5802918","type":"journal-article","created":{"date-parts":[[2018,5,14]],"date-time":"2018-05-14T19:33:58Z","timestamp":1526326438000},"page":"1-16","source":"Crossref","is-referenced-by-count":6,"title":["Context Adaptation of Fuzzy Inference System-Based Construction Labor Productivity Models"],"prefix":"10.1155","volume":"2018","author":[{"given":"Abraham Assefa","family":"Tsehayae","sequence":"first","affiliation":[{"name":"School of Civil and Environmental Engineering, Addis Ababa Institute of Technology, Addis Ababa University, Room 206, AAiT Main Building, P.O.
