No-wait hybrid flowshop scheduling: models and solotion algorithms

Bahman Naderi

Volume 14, Issue 43 , January 2017, Pages 53-77


  In this paper hybrid flowshop scheduling problem where some jobs, not all, have to follow no-wait restriction (that is, the operations of that job must be processed with no stop) is examined. In the literature, all papers assume that all jobs of the shops have to follow no-wait restrictions. First, this ...  Read More

Fuzzy multi-objective preventive maintenance and replacement scheduling using integer non-linear programming

Reza Alikhani; Mahmoud Saremi

Volume 14, Issue 43 , January 2017, Pages 79-108
