“…A major application of robots in manufacturing involves the loading and unloading of production machines in manufacturing cells. A robot in such a cell performs repeated sequences of pick-up, movement, loading, unloading and dropping operations, and thus, the performance of the cell strongly depends on the sequence of robotic activities and on the sequence of the different parts produced in the cell [4][5][6][7][8].…”

Mixed model production system means that various products are manufactured alternately in a line, and it has become a popular system in the era of multi-product small-quantity production. However, in the mixed model production system using flow line, the unbalance among stations is not inevitable because the workloads of stations cannot be the same. Thus, flow line system has been replaced to cellular manufacturing system for reducing the loss of waiting due to the unbalance of stations. In this paper, we introduce the simulation case study of an automated welding line which produces the parts of excavator. The factory has considered replacing the mixed model flow line to the cellular manufacturing system based on FMC concept. The increase of production quantity is estimated about 26.7%, and the lead time is reduced more than 55%. Furthermore sensitivity analyses are conducted considering the changes of product-mix.

“…The buffer allocation problem is a well-known problem and is widely discussed in literature [16][17][18][19][20]26]. However, specifically on buffer dimensioning, the focus in literature concerns rigid production systems [16,17,26] or generic automated flexible production systems [18].…”

“…However, specifically on buffer dimensioning, the focus in literature concerns rigid production systems [16,17,26] or generic automated flexible production systems [18]. These approaches, such as those by Senanayake et al [18] and Drobouchevitch et al [26], cannot be used to modelize and analyze robotized flexible production systems in applications where industrial robots must interact with a feeding system and a working station.…”

Automation is a powerful way to reduce production costs. The growing market demand for a wide set of models and small batch production make flexible automated production systems an emerging need in several industries. The aim of this paper is to analyze and to maximize the performance of robotized flexible production systems consisting of a robot, feeder, working station, and unloading station, where the operations of the working cycle are scheduled using a sequencing algorithm based on priority rules. Since the working cycle is not predefined, the cycle time is strongly influenced by the parameters characterizing the workcell such as the workcell layout, the robot transfer movements, the feeder, the working operations, and the presence of a buffer between stations. In this work, we modeled the working cycle of a simple but representative layout of an industrial robotized flexible production system with and without buffer, and we implemented a recursive algorithm to estimate the cycle time. The analytical model derived was compared to the experimental results, obtained by using a prototype of the flexible production workcell. The results show that the analytical model is a powerful tool to estimate the performance of the workcell and to identify the design variables or their combinations that maximize the throughput
