Workforce information is important in production planning because production planning requires matching a production unit's capacity to loads of assignments. However, tracking and managing workforce information such as skills and accident history is not an easy job. This paper describes a prototype database system for a workforce database system that employs RFID technology. This system tracks daily workforce production capacity on sites. A pilot project is described to explore the benefits and possibility of using radio-frequency identification (RFID) to track and manage workforce information, and is followed by the results of a survey to identify benefits. In addition to the survey identifying the benefits of the database system, the paper also presents a list of challenges through a series of interviews.

The lacks of local workforce supply become a problematic in Malaysian construction industry. Meanwhile, HRP is important during workforce supply to help organizations in order to appoint the right people in the right job. This paper reports on the use of factors influencing HRP towards local workforce supply in the construction industry in general, and Malaysian construction in particular. Semi structured interviews were conducted to 10 interviewees from the government and non-government organizations to investigate current issues of local workforce and the practices of HRP in the construction organization. The analysis methods were based on descriptions of previous tested research. The findings reveal that the lack of local workforce is due to low wages system, safety issues, educational changes, low status and unsecured work, environment in construction industry, developments and technologies changes in Malaysia. The internal factors of HRP were practiced among construction organization are organization strategy, organizational culture, organization changes, leadership and experience, nature of work and empowerment of labor. Meanwhile, the external factors are technology changes, economic changes, legislation and demographic changes. The paper provides valuable information on the practices of factors influencing HRP for local workforce supply in Malaysian construction industry.

It has been pointed out that the shortage of the Korean science and engineering workforce is a key issue in enterprises' competitiveness. The Korean government has conducted various surveys and research projects to determine the current situation and its causes. Nevertheless, the surveys report different results, and, to date, very few in-depth studies have been conducted on the factors that lead to such a shortage. This study aimed at investigating the factors that cause the shortage of the science and engineering workforce by looking at a recent survey on the actual employment conditions in manufacturing and major service industries. The study also estimated the determinant factors, based on the results of a survey conducted on 5,967 enterprises. Particularly, the probability of the workforce shortages are defined as a logistic probability function, which includes a diverse number of explanations that represent the characteristics of an enterprise and its internal demand conditions on workforce. The findings showed that key determinants include not only the factors that have been recognized by previous studies, but also research propensity and competitiveness aw well as the enterprises' internal demand conditions on human resources. In other words, an enterprise is more exposed to the problem of workforce shortage when it performs its R&D more proactively and its innovative activities are more organized. It has been further analyzed that the R&D and internal demand variables are more eminent to the shortage problem on skilled workers, which proves the shortage of workforce is not only caused by the quantitative aspect but also hold qualitative aspect characterized by skill obsolescence and mismatch in the labor market.

A large number of employees shifted to Work from home (WFH) due to the COVID-19 pandemic, including the construction workforce. The changes in workload and productivity due to WFH impact the work performance and economic outputs of companies. However, there are mixed results about the impacts of WFH on workload and productivity. In particular, limited studies focused on specific types of work of different occupations in the construction workforce. This study aims to explore the impacts of WFH on workload and productivity considering different types of work for the construction workforce in the U.S. After identifying three main occupations and five types of work, an online survey (N = 69) was distributed. Descriptive analysis showed that participants had less workload (0.82 hours/week) and lower productivity (9.69%) during WFH. Three occupations had varied changes due to the different types of work. Analysis of Variance (ANOVA) indicated that there was no significant difference in workload, while productivity was decreased during WFH. In particular, the productivity of project-related work and communication and documentation decreased significantly. Overall, participants finished 2.85% less workload per week during WFH. The findings provide an insight into WFH in the construction workforce, which improves future remote or hybrid work arrangements in the construction industry.

This paper considers the workforce assignment problem to minimize both the deviations of workloads assigned to workers and to maximize the total preference between each worker and each machine. Because of the high expense of technology education and the difficulties of firing employees, there is no part time workers in semiconductor industry. Therefore, multi-skilled workers are trained for performing various operations in several machines. The bicriteria workforce assignment problem in this paper is not easy to obtain the optimal solution considering the aisle structure and it is belong to NP-class. The proposed heuristic algorithms are developed based on the combination of spacefilling curve technique, simulated annealing technique and graph theory focusing on the multiple-row machine layout. Examples are presented for the proposed algorithms how to find a good solution.

In the United States, the Safety Rest Areas (SRAs) were introduced as highway roadside infrastructures in the early 1900s. The State Departments of Transportation (DOTs) operate/maintain their SRAs using different methods. The Washington DOT used the in-house workforce method for over 20 years, whereas some states moved to Performance-Based Contracting (PBC) from the in-house workforce to save cost primarily. Several existing studies claimed that using the PBC approach saved costs on several highway assets. Thus, the principal objective of this study is to compute and compare the unit operating/maintenance cost of SRAs using the in-house workforce method (in Washington state) with the PBC approach (in other states). The findings of this study show that the average annual cost using the PBC approach was much more than the average annual cost using the in-house workforce approach. The findings also show that in Washington state, the 'Labor Cost' category was a key expenditure, which is statistically higher than other categories. The 'Labor Cost' was followed by the 'Other Services', and then 'Materials and Supplies' and 'Equipment.' The study's findings indicated that outsourcing does not always save costs for agencies. The study findings may help transportation construction/maintenance professionals select a cost-effective approach for their future planning.

The purpose of this study is to analyze the influence of the economic and workforce factors on the annual number of occupational accident fatalities occurring at the construction sites. The considered variables of the economic factor are the amount of economic losses caused by industrial accidents, the GDP, and the total monthly wage for each economically active population. And, the variables related to the workforce factor are the number of economically active population, the number of female economically active population, and the number of labor union members. The multiple regression analysis was conducted to determine the effect of two factors on the total number of occupational fatalities in the construction industry. The results show that GDP among considered variables in the economic factor had a statistically significant negative relationship with the number of the construction accident fatalities in the construction industry. Among variables related to the workforce factor, economically active population showed a statistically significant negative relationship with the number of the construction accident fatalities.
