Machines are a key element in the production system and their failure causes irreparable effects in terms of cost and time. In this paper, a new multi-objective mathematical model for dynamic cellular manufacturing system (DCMS) is provided with consideration of machine reliability and alternative process routes. In this dynamic model, we attempt to resolve the problem of integrated family (par...

BACKGROUND Health-care costs for hand and forearm injuries in young children are poorly documented. We examined costs in 533 children injured years 1996-2003. METHODS Health-care costs and costs for lost productivity were retrospectively calculated in children from three catchment areas in Sweden. Seven case categories corresponding to alternative prevention strategies were constructed. RES...

In a variety of real world problems from robot navigation to logistics, agents face the challenge of path optimization on a graph with unknown edge costs. These settings can be generally formalized as the Canadian Traveler Problems (CTPs) [13]. Although in many applications the edge costs have dependencies resulting from world dynamics, CTPs with such structure have received considerably less a...

In this paper, we present a single-shift workforce planning tool: the Head Count Allocation Solver (HCA) for a high volume manufacturing facility with several machine groups at each operation. Each machine group at a given operation requires a number of workers with specified skill levels and qualifications, and each qualified worker has a preference for operations and machine groups based on h...

Combine harvesters have a very important task in grain crop harvesting. Combine harvesters must fulfil lot of technological requirements regarding the field conditions, crop type, as well as the quality performance and optimal costs. The problem is that it is the main harvesting technology of cereals in the world and it has seasonal character of work, which has to be done in a relatively short ...

In e-commerce systems, customer reviews are important information for understanding market feedbacks on certain commodities. However, accurate analyzing reviews is challenging due to the complexity of natural language processing and informal descriptions in reviews. Existing methods mainly focus on studying efficient algorithms that cannot guarantee the accuracy for review analysis. Crowdsourci...

conclusions accidents resulting in death, total disability, and partial disability impose a huge cost burden on society, whereas the employer will bear a relatively low cost. this is because of society’s health, treatment, and welfare systems available for treatment and rehabilitation of injured employees and their families. background occupational accidents represent one of the major problems ...

Machine fault diagnostic and prognostic techniques have been the considerable subjects of condition-based maintenance system in the recent time due to the potential advantages that could be gained from reducing downtime, decreasing maintenance costs, and increasing machine availability. For the past few years, research on machine fault diagnosis and prognosis has been developing rapidly. These ...

One of the goals of augmented cognition is creation of adaptive human-machine collaboration that continually optimizes performance of the human-machine system. Augmented Cognition aims to compensate for temporal limitations in human information processing, for instance in the case of overload, cognitive lockup, and underload. Adaptive behavior, however, may also have undesirable side effects. T...
