In recent years, there has been an increasing trend towards using robots in production systems. Robots are used different areas such as packaging, transportation, loading/unloading and especially assembly lines. One important step taking advantage of on the line is considering them while balancing line. On other hand, market conditions have increased importance mixed-model Therefore, this article, robotic problem studied. The aim study to develop a new efficient heuristic algorithm based...

The optimisation problems related to the assignment of tasks workstations in assembly and disassembly lines have been largely discussed literature. They are known, respectively, as Assembly Line Balancing Disassembly Problems. In this study, both types task performed on identical product integrated a common hybrid production system. Therefore, logistic process is simplified can supply easier with required components. considered system has layout two parallel workstations. flow conventional...

The disassembly line balancing (DLB) problem is the process of allocating a set tasks to an ordered sequence workstations in such way that optimizes some performance measures (e.g., number stations, hazardous components number, cycle time and work load). When operations are done on line, sometimes they need specific resources as robot, equipment, material, machine or qualified staff while working at workstation. This issue also raises resource constrained (RCDLB) problem. Therefore, this...

In this study, a mixed integer programming model for the parallel two-sided assembly line balancing problem is developed. Several extensions such as cost-oriented model, with time and space constraints assignment restrictions which considers characteristics of lines are also presented. The has been tested on number test problems from literature. results different objective functions analysed problems.

U-type and two-sided assembly lines are two types of design having advantages over traditional straight lines. In this paper, a new line hybrid is presented. A bi-objective 0-1 integer programming model developed to solve the balancing problem proposed design. Zoning constraints also considered for number test problems from literature with up 65 tasks solved. Benefits discussed.

This study introduces a new hybrid design for specific case of assembly lines, and proposes multi-pass random assignment algorithm to find the minimum number stations required. The also finds sequence schedule tasks assigned. is combination two-sided lines U-shaped which benefits from advantages both designs at same time. One side line arranged in U-shape allowing with crossovers, other balanced like traditional straight flow. Depending on product direction, either Left or Right can be...

In the assembly system, robots are able to provide enhancement on flexibility of system and automation. Each robot can perform different performance same tasks due their capabilities. Therefore, balancing robotic line (RALB) problem consists two main works, which assigning workstations, allocation in workstations. On other hand, cost is another important factor selection type high capital investment. this study, conflict objectives, minimizing cycle time, number workstation cost, considered....

Purpose Cycle time fluctuations in assembly lines are one of the important reasons re‐balancing. As a result re‐balancing lines, it will be necessary to change task sequences or equipment locations. The purpose this paper is find sequence which enables line balancing (ALB) with minimum number stations (NS) for different cycle times such that tasks and fixture locations remain unchanged. Design/methodology/approach In heuristic consist two stages proposed common lines. Findings It shown...

Montaj hattı dengeleme literatüründe hazırlık zamanlarını dikkate

Buyuk boyutlu otobus, kamyon, otomobil gibi urunlerin montaj islemleri hattin her iki tarafinda yapilabilmektedir. Boyle durumlarda tarafi (hem sag hem sol) kullanilarak islemi yapilir. Bu tip hatlar cift tarafli hatti olarak isimlendirilir. hacimli urunler uretilirken bazen ozellikli bir makineye veya bu makineyi kullanabilecek kalifiye personele ihtiyac duyulabilir. durum kaynak kisiti sorununu ortaya cikarmaktadir. yuzden literaturdeki modeller temel alinarak genellestirilmis kisitli...

Bu makalede, gorev zamanlarinin normal dagilimla ifade edildigi (stokastik) U tipi montaj hatti dengelenme problemi icin yeni bir sezgisel prosedur onerilmistir. Onerilen gelistirilirken, Arcus [16] tarafindan geleneksel, deterministik tek modelli hatlar sunulan COMSOAL metodundan faydalanilmistir. Prosedur, herbir istasyon yonetim belirlenen guvenlik seviyesi kisiti altinda, gorevlerin, sayisi enkucuklenecek sekilde atanmalarini amaclamaktadir. Prosedur, Pascal programlama diliyle...
