Otimização do processo de MRP (Material Requirement Planning) de embalagens: uma aplicação da metodologia lean six sigma em uma indústria de agronegócios

There is a growing search for continuous improvement within the companies which creates an obligation of reducing and when it is possible eliminating waste. Production Planning and Control Department (PCP) is not out of this question, making necessary the application of methods and creation of tools that eliminate steps which do not add value to the planning process. This paper aims to develop a tool which concentrates in just one place all the necessary information to make the packaging material requirement planning (MRP) in a agribusiness company. Besides, it also aims, in a more visual way and using devices that prevent mistakes (Poka-Yoke), to reduce the number of reviews and mistakes made by analysts. As a result, an Excel spreadsheet was developed. This spreadsheet shows what happens with the status of planning and receiving of packaging, giving some advices when some critical situation happens. The use of Lean Manufacturing Method and the action research method helped to well define the problem and to reduce the number of steps, spreadsheets and time of process in 80%, 60% and 75%, respectively

Aplicação do DMAIC em uma indústria farmacêutica

In an industry, being a big one or small one, the process improvement is always a focus for it to increase in the market. The improvement, if searched in a simple meaning, brings the unique meaning of change to better. However the meaning of process improvement can take much more than a superficial point of view. Kaizen, Process improvement, Continuous improvement, they are some denotations much more comprehensive of a such a term carried of so many meanings. A good concept of improvement if to search inside processes a more appropriate way, a more succinct, a more economic way to realize it. The idea is to make the process in a better way.

Ecocentro Despertar

Diante dos preocupantes problemas ambientais causados ao nosso planeta, sabe-se que a sua maioria está relacionada ao uso abundante e inconsequente dos recursos naturais, e que estes problemas são consequência direta da intervenção humana nos diferentes ecossistemas da Terra, causando desequilíbrios no meio ambiente e comprometendo a qualidade de vida. No Brasil, aproximadamente 40% da extração de recursos naturais têm como objetivo a indústria da construção. Sabe-se que 50% da energia gerada é para abastecer somente o funcionamento das edificações e 50% dos resíduos sólidos urbanos vêm das construções e demolições, os chamados “entulhos”. Frente a isso, profissionais começaram a pensar em alternativas para utilizar cada vez menos energia proveniente de combustíveis fósseis não renováveis, como os arquitetos que passaram a estudar os princípios bioclimáticos para reduzir as necessidades energéticas das edificações e assegurar o conforto com métodos construtivos ecológicos. Tendo em vista a importância da Sustentabilidade para o mundo em que vivemos, este trabalho consiste no projeto de uma edificação independente do uso de combustíveis fósseis e de energias geradas por fontes que agridem o meio ambiente. A proposta se baseia no projeto sustentável de um Centro Comunitário para os bairros Morada do Sol e Belo Galindo, em Presidente Prudente, SP
