Facility layout selection guideline under dynamic demand and part variety

Assessment of shop floor layouts in the context of process plans with alternatives

“…In general, such different results found in the case of the traditional cell layout can be understood by the wide variety of parts. Similar results were found by Ramachandran & Prasad (2014). All parts in each batch were generated from 40 pre-established features, and Excel's random function resulted in high batch variability, leading to a poor performance of the traditional cell layout.…”

“…Moreover, as Ramachandran & Prasad (2014) suggest, the transition from the job shop layout to the virtual cell layout is easier when compared with the costs involved in the case of the transition to the traditional cell layout.…”

“…It is observed that the authors listed in table 1 developed mathematical models for the formation of virtual cells, using the most varied techniques. It is worth highlighting the paper by Ramachandran & Prasad (2014), which performs a comparison of layouts. Among the differences of the Ramachandran & Prasad (2014) proposal for the presented research is the design of experiments that aided in the identification of the main control factors that affect the results.…”

“…Paydar & Saidi-mehrabad (2017) cite as an advantage of virtual cells the fact that the cellular arrangement occurs virtually, which is appropriate in the case of significant variations in the demand of parts, not being necessary the physical rearrangement of machines. Ramachandran & Prasad (2014) cite the better performance of the virtual cell layout in different scenarios. It is worth mentioning the swiftness with which the system responds to demand changes.…”
