A GRASP algorithm is presented for solving a sequencing problem in a mixed-model assembly line. The problem is focused on obtaining a manufacturing sequence that completes the greatest possible amount of required work and fulfils the production regularity property. The implemented GRASP algorithm is compared with other resolution procedures by means of(More)
In this paper, we present an extension to the TSALB problem (Time and Space constrained Assembly Line Balancing) with ergonomic risk restrictions. This ergonomic risk is defined from the task durations and their categories regarding to the risk factor for the workers. A study is presented through a case linked to an engine assembly line in the Automobile(More)
An error has slipped in the Appendix. In the definitions of the variables z + i,t and z − i,t the right texts are: z + i,t Binary variable equal to 1 if X i,t (i ∈ I, t = 1,. .. , T) is greater than the upper limit of production mix preservation and to 0 otherwise z − i,t Binary variable equal to 1 if X i,t (i ∈ I, t = 1,. .. , T) is less than the lower(More)
