This study proposes a simulated annealing-based approach for simultaneously solving balancing and sequencing problems of mixed-model U-lines. The proposed approach is capable of minimizing the number of workstations required on the mixed-model U-line as well as minimizing absolute deviation of workloads (ADW) among workstations. An experiment to evaluate the performance of the algorithm is also...

This paper investigates the integration of strategic and tactical decisions in the supply chain network design (SCND) considering assembly line balancing (ALB) under demand uncertainty. Due to the decentralized decisions, a novel bi-level stochastic programming (BLSP) model has been developed in which SCND problem has been considered in the upper-level model, while the lower-level model contain...

Recently Indonesian textile and garment manufacturer has experienced a problem with shop floor production. The complexities in the manufacturing process led to many problems such as inefficiency, thus prevented company from achieving its target. In fact, even though established efficiency target of 80%, production cannot realize it. Thus, this research aims increase line reach company’s At begi...

Assembly line balancing concerns the design of assembly lines for the manufacturing of products. In this paper we consider the time and space constrained simple assembly line balancing problem with the objective of minimizing the number of necessary work stations. This problem is denoted by TSALBP-1 in the literature. For tackling this problem we propose a Beam-ACO approach, which is an algorit...

The paper deals with a transfer line optimal desing. In contrast to the known assembly line balancing problem, for considered transfer lines, operations are grouped into blocks of parallel operations. Each block is executed by one spindle head. Spindle heads allocated to each station can be activated both sequentially and simultaneously, i.e. in a mixed order. The set of all available spindle h...

Assembly lines are special flow-lines production systems which are typical in the industrial production of high quantity standardized commodities. Assembly line balancing is based on evenly distribution of operations between workstations so that each idle time of the machines was minimal. It is assumed that operation times on the machines and the precedence relationship existing between the ope...

This paper deals with the use of fuzzy set theory as a viable alternative method for modelling and solving the stochastic assembly line balancing problem. Variability and uncertainty in the assembly line balancing problem has traditionally been modelled through the use of statistical distributions. This may not be feasible in cases where no historical data exists. Fuzzy set theory allows for th...
