Mixed-model U-shaped assembly line balancing problems (MMUALBP) is known to be NP-hard resulting in it being nearly impossible to obtain an optimal solution for practical problems with deterministic algorithms. This paper presents a new evolutionary method called combinatorial optimisation with coincidence algorithm (COIN) being applied to Type I problems of MMUALBP in a just-in-time production...

The motivation of our work is from the paper by Chen et al. (2012) in which the assembly line balancing (ALB) problem in the garment manufacturing process for a single model is solved by using genetic algorithm. Out of four steps of manufacturing the product, we focus on the third step in their paper in which there is a sewing line which is to be operated by different employees having different...

Line-integrated supermarkets constitute a novel in-house parts logistics concept for feeding mixed-model assembly lines. In this context, supermarkets are decentralized logistics areas located directly in each station. Here, parts are withdrawn from their containers by a dedicated logistics worker and sorted just-in-sequence (JIS) into a JIS-bin. From this bin, assembly workers fetch the parts ...

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...

atholic health care finds itself within a rapidly changing landscape. In response, some Catholic hospitals and collaborative health systems are making structural changes. Some systems have decided to forego formal recognition by the local bishop, for example, while a few hospitals and systems have begun to explore for-profit corporate structures. These and other new models-in-the-making may hav...

Abstract Assembly lines with fractional tasks increase the throughput a better workload balancing among stations. The possibility to share between two consecutive stations can also support design of assembly redundancies tasks. redundancy allows reacting short failures or variations in processing time. This paper proposes framework and control lines. first problem concerns modified mixed-intege...

Automatic in-process data collection techniques have been widely used in complicated manufacturing processes in recent years. The huge amounts of product measurement data created great opportunity for process monitoring and diagnosis. Given such product quality measurements, this article examines the diagnosability of the process faults in a multistage manufacturing process using a linear mixed...

The recently introduced Response Time Variability Problem (RTVP) is a scheduling problem that has a broad range of real-life applications, for example, to sequence the models to be produced on a mixed-model assembly line. Previous studies include heuristic algorithms and mathematical programming models, whose practical limit for obtaining optimal solutions is around 40 units to be scheduled. In...
