Optimizing a U-Shaped Conveyor Assembly Line Balancing Problem Considering Walking Times between Assembly Tasks

نویسندگان

چکیده

This research deals with a U-shaped assembly line balancing problem in which items are fixed on the conveyor. Operators execute tasks without removing from conveyor as assumed to be unsuitable for manual handling. The operators have walk beside at same speed while they tasks. If want assemble other items, may positions their normal walking speed. Therefore, cycle time of an operator should include times and between In this research, mathematical model proposed was developed. Given number operators, can optimize sequence allocation workstations using commercial software LINGO 17. Because 17 requires long computing time, simulated annealing (SA), accept worse new solutions search procedure, is proposed. experimental results show that SA efficiently.

genetic algorithms for assembly line balancing problem

there are some machineries and equipments as well as relatively fix amount of human resources involved in any production process. in many cases, by observing operational method of a process, one may see that some of these machineries are not working, but on the other hand, other equipments are continuously working, and many parts are set in front of them, waiting to be set up over machines to c...

Mixed-Model Assembly Line Balancing with Considering Reliability

This paper presents a multi-objective simulated annealing algorithm for the mixed-model assembly line balancing with stochastic processing times. Since, the stochastic task times may have effects on the bottlenecks of a system, maximizing the weighted line efficiency (equivalent to the minimizing the number of station), minimizing the weighted smoothness index and maximizing the system reliabil...

‘BALANCING AND SEQUENCING’ VERSUS ‘ONLY BALANCING’ IN MIXED MODEL U-LINE ASSEMBLY SYSTEMS: AN ECONOMIC ANALYSIS

With the growth in customers’ demand diversification, mixed-model U-lines (MMUL) have acquired increasing importance in the area of assembly systems. There are generally two different approaches in the literature for balancing such systems. Some researchers believe that since the types of models can be very diverse, a balancing approach without simultaneously sequencing of models will not yield...

Assembly line balancing problem with skilled and unskilled workers: The advantages of considering multi-manned workstations

This paper address a special class of generalized assembly line balancing in which it is assumed that there are two groups of workers: skilled and unskilled ones. The skilled workers are hired permanently while the unskilled ones can be hired temporarily in order to meet the seasonal demands. It is also assumed that more than one worker may be assigned to each workstation. To show the adv...

Balancing of parallel U-shaped assembly lines

A new hybrid assembly line design, called Parallel U-shaped Assembly Line system, is introduced and characterised along with numerical examples for the first time. Different from existing studies on U-shaped lines, we combine the advantages of two individual line configurations (namely parallel lines and U-shaped lines) and create an opportunity for assigning tasks to multi-line workstations lo...
