This paper presents a nonlinear mixed-integer programming model to minimize the stoppage cost of mixed-model assembly lines. Nowadays, most manufacturing firms employ this type of line due to the increasing varieties of products in their attempts to quickly respond to diversified customer demands. Advancement of new technologies, competitiveness, diversification of products, and large customer ...

The ANTARES Collaboration is building a neutrino telescope 2400 m below the Mediterranean sea close to the Southern French coast. The site is already linked to the shore station by a 40 km-long electro-optical cable (EOC) which transmits power and data. A prototype line and an instrumentation line for monitoring environmental parameters have been successfully deployed and connected to the EOC v...

Electrical companies routinely inspect their overhead lines by helicopter. Current detailed aerial inspection approach uses trained inspectors who fly aboard helicopters to inspect the lines with binoculars and cameras, while recording the data in a logbook. The procedure is performed while the helicopter hovers over and around power lines and structures, creating an element of danger for the p...

This research addresses the mixed-model assembly line (MMAL) by considering various constraints. In MMALs, several types of products which their similarity is so high are made on an assembly line. As a consequence, it is possible to assemble and make several types of products simultaneously without spending any additional time. The proposed multi-objective model considers the balancing and sequ...

Background: Work-related musculoskeletal disorders (WMSDs) may involve all parts of the body, and have been a worldwide problem. Employed women are two to five times more likely to report such problems, and assembly lines suspected to induce more WMSDs because of high rate of repetitive motions. Methods: The aim of this study to determine the prevalence of WMSDs in women workers of an automobi...

Carbon Dioxide Removal Assembly (CDRA) is one of the most important systems in the Environmental Control and Life Support System (ECLSS) for a manned spacecraft. With the development of adsorbent and CDRA technology, solid amine is increasingly paid attention due to its obvious advantages. However, a manned spacecraft is launched far from the Earth, and its resources and energy are restricted s...
