Flexibilitätsbasierte Gestaltung der logistischen Auftragsabwicklung – Anwendung am Beispiel von Produktionsdienstleistern

Teich, Enrico 10 October 2014 (has links)
Zur Bewältigung von Belastungsschwankungen in der industriellen Produktion – der systematischen Regelung von Kapazitätsangebot und -bedarf – existieren Methoden in der logistischen Auftragsabwicklung, deren Anwendungserfolg von den im Produktionsbereich vorhandenen Kapazitäts- und Belastungsflexibilitätsmaß abhängig ist. Die Entwicklung geeigneter Verfahren zur Messung dieser Flexibilitätstypen als auch von Ansätzen zur Nutzung der Messwerte bei der Gestaltung der logistischen Auftragsabwicklung sind die Zielsetzungen dieses Forschungsvorhabens. Vor allem Produktionsdienstleister sind aufgrund ihrer unternehmenstypspezifischen Merkmale für die Validierung der Entwicklungsarbeit sowie die spätere Verwertung der Forschungsergebnisse prädestiniert.

Softwarová podpora plánování výroby / Software Support of Production Planning

Vaculková, Petra January 2018 (has links)
This Master´s thesis analyzes the software support of production planning in 2VV Ltd., which deals with manufacturing and suppling air conditioning systems as are air curtains, ventilation units and ventilation products. This thesis is divided into three parts. The theoretical part describes the theoretical base of manufacturing, production planning process and its software support. The analytical part contains global analysis and critical analysis of the current status of order processing and production planning with software support and its results. The last part lists possible improvements of production planning in the company.

Um problema de corte de peças integrado à programação da produção - uma abordagem por relaxação lagrangiana / A cutting stock problem integrated to the production programming. An lagrangian relaxation approach

Biehl, Scheila Valechenski 20 March 2008 (has links)
O problema de planejamento da produção integrado ao problema de corte de estoque surge em várias indústrias de manufatura, tais como indústria de papel, móveis, aço entre outras, e consiste em um problema de otimização combinatória bastante complexo, devido ao fato de integrar dois problemas conhecidos na literatura de difícil resolução. As aplicações práticas deste problema vêm aumentando em muitas empresas que buscam tornar seus processos produtivos mais eficientes. Neste trabalho, estudamos o problema de otimização integrado que surge em pequenas indústrias de móveis, em que placas de MDF disponíveis em estoque devem ser cortadas em itens menores, de diversos tamanhos e quantidades para comporem os produtos demandados. O modelo matemático de otimização linear inteiro proposto permite que alguns produtos sejam antecipados e estocados. Essa antecipação da produção aumenta os custos de estoque, porém com o aumento da demanda de peças é possível gerar padrões de corte melhores e diminuir os custos com a perda de material. Consideramos no modelo dois tipos de variáveis de antecipação, uma de estoque convencional para atender uma demanda em carteira e outra para aproveitar a produção e atender uma demanda prevista, chamada variável oportunista. A função objetivo consiste em minimizar os custos dos processos de produção e de corte. Para resolver a relaxação linear deste problema, propomos um método lagrangiano e utilizamos a estratégia de horizonte rolante. Alguns testes computacionais são realizados e os resultados apresentados / The integrated problem of cutting stock and production planning arises in a several manufacturing industries, such as paper, furniture, steel among others, and it is a complex combinatorial optimization problem, due to the fact that it integrates two well-known NP problems of the literature. The real world applications of this problem have increased in many industries that search for more efficient production process. In this work, we studied an integrated optimization problem that arises in small furniture industries, where MDF boards available in inventory must be cut into enough quantities of items to compose demanded finish-goods. The model of integer linear optimization proposed allows anticipating some products and keeping them in inventory. This production anticipation makes increase the inventory costs, although makes it possible to determine better cutting patterns and decreases the costs of the cutting process. We consider in the model two types of anticipation variables, the first one to the ordinary inventory to meet ordered products and an other one, called chance variables, to meet a forecasting demand. The objective function is to minimize the costs of production process and waste of material. To solve a linear relaxation of this problem, we proposed lagrangian approach and used a rolling horizon strategy. Some computational tests are performed and results shown
