A decision support system for design of mass production machining lines composed of stations with rotary or mobile table

Variety-oriented design of rotary production systems

“…Constraints (6) prohibit assignments of operations for machining elements located at two different sides of the part to a vertical spindle head (or turret). Constraints (7) ensure that all operations for machining elements located at the same side of the part will be assigned to the same type of spindle head or turret. Constraints (8)- (9) provide the precedence relations for the operations that require either the same type of machining module (vertical or horizontal) or different ones, respectively.…”

“…the fixtures of parts are changed and some spindles are mounted or dismounted if necessary. However, few studies published in the literature on the design of rotary production systems were mostly dedicated to the mass production case [7][8][9][10][11][12]. In difference to that previous work, this paper considers the case of the production of different variants of a product family.…”

Combinatorial techniques to optimally customize an automated production line with rotary transfer and turrets

“…The idea to use a constrained shortest path approach has already been applied to the design of transfer lines and different multi-positional machines Battaïa et al, 2012aBattaïa et al, , 2012b as well as for the design of reconfigurable manufacturing systems (Dou et al, 2009(Dou et al, , 2011. Since it is known to be efficient when solving real-world problem instances (Zhu and Wilhelm, 2013), this idea is developed here for the problem of customization of automated lines with rotary transfer and turrets.…”

“…The configuration of semi-automated systems with a multi-turn rotary table was discussed in Battini et al (2007). Mathematical models of transfer machines with rotary or mobile tables were proposed in Guschinskaya Dolgui et al (2008), ), and Battaïa et al, (2012a, 2012b. Unfortunately, the principal advantage introduced by the use of turrets, the possibility of serial-parallel machining, cannot be taken into account by these models where only machining modules activated in series or in parallel are considered.…”

Decision support for design of reconfigurable rotary machining systems for family part production

“…The design of transfer machines with rotary or mobile tables was mostly studied for mass production (Szadkowski 1971;Dolgui, Guschinsky, and Levin 2009;Battaïa et al 2012). For such machining systems, the reconfiguration process is not effortless, is costly and requires solving a specific optimisation problem as it was studied in (Makssoud, Battaïa, and Dolgui 2014).…”
