Integrated FAHP-FDEMATEL for determining causal relationships in construction crew productivity modelling
Download2023-01-01
Kedir, Nebiyu, Fayek, Aminah Robinson
Construction crew productivity is affected by the motivation of the crew performing given activities and by situational/contextual factors forming the dynamic construction environment. The literature lacks a comprehensive analysis of causal relationships between crew motivation and...

Interactive allocation of mobile photo enforcement resources with multiple program objectives
Download2019-11-06
Li, Y., Kim, A., El-Basyouny, K.
Managers of mobile photo enforcement (MPE) programs must account for several road safety goals when deploying operators. However, there is no MPE design structure to systematically connect deployment decisions back to preset goals. We propose a method to aid MPE managers in using goals directly...

Li, Y., Xie, J., Kim, A. M., El‐Basyouny, K.
Agencies that manage mobile photo enforcement (MPE) programmes must decide where and when to send their limited resources to monitor compliance with speed limits. Usually, the goal is to select locations based on a number of concerns (i.e., high collision sites, high speed violation sites, school...

Raoufi, Mohammad, Fayek, Aminah Robinson
Construction crew performance is a function of both motivation and the situation in which tasks are performed. However, previous research in construction has not comprehensively investigated situational/contextual factors and their impact on the relationship between motivation and performance....

Long-Distance Airport Substitution and Air Market Leakage: Empirical Investigations in the U.S. Midwest.
Download2021-05-08
Yirgu, Kaleab Woldeyohannes, Kim, Amy M., Ryerson, M.S.
Following airline mergers and network reorganizations aimed at reducing operational costs, consolidated air services at large hub airports have encouraged air travelers to forego use of their smaller local airports to access large hub airports offering superior air services farther away. This...

Cabral, L., Kim, A. M., Shirgaokar, M.
Studies have shown that a network of safe, connected, and direct facilities can increase urban cycling levels. During summer 2017, the city of Edmonton, Canada, constructed nearly 20 kilometers of protected bicycle lanes on its core neighborhood streets. A rapid and coordinated network...

Naphthenic acids (NAs) originate from bitumen and are considered a major contributor to acute toxicity in oil sands process-affected water (OSPW) produced from bitumen extraction processes. To reclaim oil sands tailings and remediate OSPW, in-pit fluid fine tailings can be water-capped as end pit...

Seresht, Nima Gerami, Fayek, Aminah Robinson
Predicting and optimizing performance in earthmoving operations is critical, because they are essential to many construction projects. The complexity of modeling earthmoving operations remains challenging, even with several modeling techniques available, including simulation. This paper advances...

Seepage from oil sands tailings ponds (OSTP), which contain toxic naphthenic acids (NAs), can infiltrate into groundwater. Clay sediment layer beneath is a critical barrier for reducing the infiltration of NAs into the sand sediment layer, where groundwater channels reside. Biodegradation has...

The performance of construction systems (e.g., activities, operations, projects) is commonly measured using different indicators, such as productivity or production rate. The accurate prediction of performance, which is an important concern of construction researchers and practitioners, requires...
