Purpose This paper aims to propose an improved Moth Flame Optimization (I-MFO) algorithm to optimize the cost-oriented two-sided assembly line balancing (2S-ALB). Prior to the decision to assemble a new product, the manufacturer will carefully study and optimize the related cost to set up and run the assembly line. For the first time in ALB, the power cost is modeled together with the equipment, set up and labor costs. Design/methodology/approach I-MFO was proposed by introducing a global reference flame mechanism to guide the global search direction. A set of benchmark problems was used to test the I-MFO performance. Apart from the benchmark problems, a case study from a body shop assembly was also presented. Findings The computational experiment indicated that the I-MFO obtained promising results compared to comparison algorithms, which included the particle swarm optimization, Cuckoo Search and ant colony optimization. Meanwhile, the results from the case study showed that the proposed cost-oriented 2S-ALB model was able to assist the manufacturer in making better decisions for different planning periods. Originality/value The main contribution of this work is the global reference flame mechanism for MFO algorithm. Furthermore, this research introduced a new cost-oriented model that considered power consumption in the assembly line design.

For every manufacturing organization, price of the product primarily comprises of manufacturing cost and desired profit. If a company wishes to increase its profit, one way is to reduce the manufacturing cost with maintaining the quality of the product. Waste reduction, especially the (wait) time waste, is an important factor to shrink the manufacturing cost. The purpose of this paper is to identify and address the way to reduce idle time in the apparel manufacturing organization using various line balancing technique to improve productivity and efficiency in domestic context. Line balancing job has been done through the ‘Largest Candidate Rule’ and ‘Ranked Positional Weight Technique’. Using these techniques, a software has been developed to arrange the elemental tasks in the workstation, and to show the balancing efficiencies of each method and other important information. The overall job may be very helpful in some decision making process of the organization. At last an efficient and balanced line has been proposed through the study.

Sustainability evaluation of manufacturing technologies is a vital part of decision process in sustainable manufacturing, particularly for decisions on transfer/adoption of new sustainable manufacturing innovations. This paper highlights a study on metrics-based sustainability evaluation of technologies in manufacturing, with emphasis on the technical, economical and environmental sustainability assessments. On the basis of three types of sustainability evaluation metrics proposed in this paper, our study integrates technology assessment, cost analysis and environmental evaluation to support decision-making for selection of sustainable manufacturing processes. Case studies about sol-gel coating and powder coating are explored in the paper to test the proposed sustainability evaluation methods and metrics. The assessment results provide quantitative justifications used in technology transfer of the new sol-gel coating innovations. The results also help potential technology adopters to reduce their implementation risks of the sol-gel coating process in automotive decorative applications.

In Line Balancing principles, the total workload in the assembly process is divided as evenly as possible among the workstations, without violating the sequences and relations in the assembly operations. Line balancing is important in an assembly system as it balances the line and increases the efficiency, as well as the productivity of a system. A case study was conducted in the assembly line of an electrical accessories manufacturer in Malaysia. The cycle time for each station was recorded, and the standard cycle time was estimated. The productivity, as well as the efficiency of the current assembly line, were studied. In terms of the productivity, the performance of the current systems was 500 units/worker/day, while the expected productivity was 600 units/worker/day. An assembly line setting was proposed based on the Line Balancing Method; the productivity for the proposed line increased to 671 units/worker/day, or in rough additional increase around 34%.

Produzir mais, empregando menos tempo e menos recursos, é o sonho de qualquer empresa. Diante disso, este estudo busca resolver problemas de utilização da capacidade e de desnivelamentos de produção. Dessa maneira, o objetivo consiste em propor um formato de programação que otimize a utilização dos recursos e resulte em maior equilíbrio na produção de uma empresa do ramo metalúrgico, produtora de implementos rodoviários e localizada na região Sul do Brasil. Por meio de um estudo de caso, identificaram-se a forma de trabalho e a situação da programação da empresa. A partir disso, criou-se um modelo de um novo formato de produção, voltado à minimização das variações de volumes e fundamentado, basicamente, na utilização dos conceitos de takt time e de balanceamento das linhas. Conclui-se que o modelo proposto permitirá um ritmo continuado na produção, sendo capaz de estabilizá-la. Ademais, conforme for aplicado nas linhas da empresa, evidenciará os pontos ao longo do fluxo que precisam de melhoria, identificando gargalos e ociosidades. A soma de tais fatores proporcionará o aprimoramento contínuo dos processos da empresa e a otimização dos recursos disponíveis para a produção. Palavras-Chave: Linha de produção. Programação de produção. Takt time. Balanceamento de linha. Capacidade produtiva.   Abstract: Producing more, using less time and fewer resources, is the dream of any company. Therefore, this study seeks to solve problems of capacity utilization and production unevenness. Thus, the objective is to propose a programming format that optimizes the use of resources and results in greater balance in the production of a company in the metallurgical sector, producer of road implements and located in the southern region of Brazil. Through a case study, the way of working and the situation of the company's programming were identified. From this, a model of a new production format was created, aimed at minimizing volume variations and basically based on the use of the concepts of takt time and line balancing. It is concluded that the proposed model will allow a continued pace in production, being able to stabilize it. Furthermore, as applied to the company's lines, it will highlight the points along the flow that need improvement, identifying bottlenecks and idleness. The sum of these factors will provide the continuous improvement of the company's processes and the optimization of the resources available for production. Keywords: Production line. Production schedule. Takt time. Line balancing. Productive capacity.
