Implementation of lean manufacturing techniques in the bakery industry in Medellin

Abstract

The bakery industry has great economic and social importance in the city of Medellin; most of the companies are small with high levels of informality, low value added and productivity. Lean Manufacturing has become one of the most popular paradigms of waste disposal in the industrial sector and services, with great benefits of their practice on the improvement of the quality and organizational productivity. This work evaluates the level of implementation of the lean manufacturing techniques in the micro and small enterprises in Medellin, in the food sector. It was using diagnostic and follow-up tools with questionnaire to the production chief, which include 9 techniques or tools, and a variable of administration that allow organizations to a guide, to improve the current conditions of productivity. The main results show that the outstanding Lean practices are: PokaYoke, Kaizen and visual factory. However, for which the sector is considered to be of world class, the practices must be strengthened: VSM (generation of value), JIT (Production Flow) and ADMON (Administration). In addition, organizations must increase sales least 139, 20% to increase the level of efficiency of the sector, without changing the number of employees.

Proposta de melhorias no processo de produção de uma panificadora a partir de ferramentas do lean manufacturing

“…Os autores identificaram a melhora de produtividade em 7 pães na produção a partir da utilização do 5S e alteração do layout de fábrica permitido por meio da sugestão observada no diagrama de desperdícios. Castro & Posada (2019) 3 Procedimentos metodológicos O presente trabalho é classificado como um estudo de caso pois promove um melhor entendimento de eventos empíricos e as suas investigações provocam observações e oportunidades de pesquisas futuras (Yin, 2004). Além disso, a pesquisa apresenta caráter exploratório uma vez que envolve o levantamento bibliográfico, entrevistas com pessoas envolvidas no problema e análise de exemplos (Gil, 2002) pois realiza-se uma investigação, permitindo amplo e detalhado conhecimento (Miguel, 2012).…”

“…Castro & Posada (2019) eCosta et al (2018) destacaram o fator de perecibilidade, manuseio e manutenção dos equipamentos específicos dos materiais envolvidos nos processos da indústria alimentícia como agentes que diferenciam a aplicabilidade do lean nessas organizações para os outros segmentos. Estes fatores podem sugerir os motivos relacionados à carência de investigação por meio de pesquisas neste setor.…”

Sustainable Lean Manufacturing model to reduce waste in a dairy company in Peru

“…For example, food processing industries may present various seasonal patterns or patterns of raw materials and processing equipment [20]. Currently, Lean practices have become essential in various manufacturing sectors, including electronics, plastics, textiles, food, dairy, foundry, and maintenance [5,6]. Today, Lean practices have become essential.…”

“…Therefore, new approaches are needed for the management of food waste in its processing [5]. Waste management is sustainable when material resources are used efficiently to reduce the amount of waste produced and sustainable development goals are promoted [19].…”

“…Lean Manufacturing has been proposed as a solution to the various existing production chains in the market because each tool helps to eliminate one of the eight wastes: [7]. (1) defects, when something goes wrong; (2) overproduction, doing more than is required; (3) wait, wait for something to happen; (4) not using the talent of the staff; (5) transportation; (6) inventories, product without continuous flow; (7) movement, that the operator moves from his workstation; (8) extra-processing [13,14]. On the other hand, the milk processing industry presents a series of difficulties, some such as surplus milk, inefficient production systems, reprocessing, food waste and contamination, acid, and pH measurement errors.…”
