Predicting Maximum Work Duration for Construction Workers

چکیده
One of the most common health problems that threaten transportation infrastructure construction workers in Hong Kong is heat stress. An effective way to reduce this problem design a proper work–rest schedule, and key issue predicting maximum working duration given different conditions surrounding environment, which research question study. Air temperature, an important input feature, also determined by itself, i.e., feature function prediction target. Therefore, model developed from ordinary models hard solve standard statistical or machine learning models. For process, trial-and-error algorithm proposed derive solution based on two theorems are rigorously proved; there exists unique solution, within certain range model. The its approach were constructed validated using simulated data; temperature data collected Observatory. results showed mean squared error (MSE), absolute percentage (MAPE), R2 test set 0.1378, 0.1123, 0.8182, respectively, showing performance was generally accurate. This study can help practitioners governments rationally schedules thus protect them risks brought about

متن کاملA Humanoid-robotics Method for Predicting Construction Work Performance
A major obstacle to the refinement of modem construction engineering practice is the inability of the industry to exactly predict (in some theoretical rigorous manner) the beforethe-event performance of construction workers in the execution of particular tasks or to account for the actual method or systems of work employed or to allow for small changes in the task or in its solution technology....
متن کاملInvestigating relationship between sleep disorders and work ability among workers in construction workshops
Introduction: Sleep is one of the important physiologic needs in daily life cycle, and a part of quality of life. Sleep disorders are considered as one of the most common health problems in work communities that can affect physical, mental performance and ability to work. Therefore, this study aimed at investigating the relationship between sleep disorders and work ability in construction worke...
