Multi-Period Production Capacity Planning for Integrated Product and Production System Design

Abstract

.Abstract -This paper presents a simulation-based method to aid multi-period production capacity planning by quantifying the trade-off between product quality and production cost. The product quality is estimated as the statistical variation from the target performances obtained from the output tolerances of the production machines that manufacture the components. The production cost is estimated as the total cost of owning and operating a production facility during the planning horizon. Given demand forecasts in future production periods, a multi-objective genetic algorithm searches for the optimal types and quantity of the production machines to be purchased during each period, which simultaneously maximize the product quality and minimize the production cost during the entire planning horizon. Case studies on automotive valvetrain production are presented as a demonstration.

Planejamento da capacidade de produção na indústria plástica: uma abordagem baseada em previsão de demanda e níveis de capacidade

“…O planejamento da capacidade é a atividade de analisar e tomar decisões visando equilibrar o nível de produção ou serviços com a demanda de mercado, decidindo também como esta deve reagir frente aos desafios provocados pela flutuação na demanda (KAZANCIOGLU e SAITOU, 2006). Para enfrentar estes problemas, Volling et al (2013) destacam as vantagens da utilização de instrumentos que propiciem flexibilidade aos sistemas de produção.…”

“…No estudo apresentado por Kazancioglu e Saitou (2006), um método baseado em simulação busca determinar a capacidade ideal, maximizando a qualidade do produto e minimizando os custos de produção.…”

An Integrated Optimization Model for Product Design and Production Allocation in a Make to Order Manufacturing System

“…A class of production systems, similar to the research of Kazancioglu and Saitou (2006) is considered in this research. The company received orders from its customers in the form of assembly products in which each assembly consists of several components.…”

“…The objective of the model was to minimize quality cost, inventory cost, and operation cost of a machine at specific work station. Kazancioglu and Saitou (2006) developed a multi-period production capacity planning for an integrated product and production system design. The model used two stages in decision making.…”

“…Their model was similar to the process selection model with one exception that the process selection needs a process sequence and consequently, the intermediate tolerance is needed in the model. Ming and Mak (2001) developed an intelligent approach to tolerance allocation and manufacturing operations selection in process planning. The model is applicable to the system in which a feature has several process sequences.…”
