This paper reviews and utilizes the current body of telecommuting related research to study the costs and benefits of home-based telecommuting. Monte Carlo simulation methods were utilized to help account for costs or benefits that remain highly variable or have not been well documented by past research. This study illustrates the conditions under which the business case for telecommuting is su...

Previous studies report that truck drivers are at increased risk for illness and on-the-job mortality. It is unknown whether owner-operator truck drivers face the same risks as employee drivers, yet few studies have targeted owner-operators as a study population. This study examined the overall and cause-specific mortality ratios for a cohort with owner-operator truck drivers constituting 69% o...

In this paper, we first illustrate the state-of-the-art in timetabling research w.r.t. two important research qualities, namely measurability and reproducibility, analyzing what we believe are the most important contributions in the literature. Secondly, we discuss some practices that, in our opinion, could contribute to the improvement on the two aforementioned qualities for future papers in t...

In this paper we address the container security problem and we investigate RFID-enabled innovative solutions to confront it. To that end, initially we set the scene of the problem by reporting existing security problems in ocean container transport and container security-originated initiatives and regulations that affect seaborne containers transportation and handling. Afterwards, we accomplish...

To fix ideas, we can think of the graph as a public transportation network, where each edge represents a bus route connecting two stations. The n players can be thought of as employees that want to commute from their home stations si to a company located at station t. Assume that the operation of each route requires a fixed amount of money, say one unit of cost, which people using that route ca...

In this paper, we first discuss the level of compliance for timetabling research to two important research qualities, namely measurability and reproducibility, analyzing what we believe are the most important contributions in the literature. Secondly, we discuss some practices that, in our opinion, could contribute to the improvement on the two aforementioned qualities for future papers in time...
