An employee transporting problem is described and a set partitioning model is developed. An investigation of the model leads to a knapsack problem as a surrogate problem. Finding a partition corresponding to the knapsack problem provides a solution to the problem. An exact algorithm is proposed to obtain a partition (subset-vehicle combination) corresponding to the knapsack solution. It require...

This article is based on a study that analyzed the impacts of employer-based transportation demand management (TDM) strategies and the performance of a transportation system. The study simulated the effects of the Washington State Commute Trip Reduction (CTR) programs implemented by 189 employers on an 8.6-mile segment of I-5 in the Seattle downtown area. This comprehensive dataset included bef...

Workplace drug screening was introduced in the United States in the 1980’s. President Ronald Reagan issued an order stipulating mandatory drug testing for every safety-sensitive (i.e. transportation), civil service and executive level federal employee. In 1988, drug testing legislation was passed to permit private employers to introduce policies concerning drug testing. The primary motivation f...

Employee scheduling is a well known problem that appears in a wide range of different areas including health care, air lines, transportation services and basically any organization that has to deal with workforces. In this paper we model a collection of challenging staff scheduling instances as a weighted partial boolean maximum satisfiability (maxSAT) problem. Using our formulation we conduct ...

OBJECTIVE To investigate the correlates of job boredom in 87 Finnish workplaces (N = 11,468) and to examine the associations between job boredom, health outcomes, and job attitudes. METHODS We applied the Dutch Boredom Scale to measure job boredom. Hierarchical logistic regression analysis and odds ratio estimates were used for further examination of the variables. RESULTS Male, under-36-ye...

in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...
