“…This assumption is absolutely unrealistic for a wide range of manufacturing systems where the production process is subject to quality deterioration (Rivera-Gomez et al, 2013a). In addition, while several studies have shown the strong interdependencies between quality, maintenance and productivity (Ben-Daya and Duffuaa, 1995;Lee et al, 2007;Colledani and Tolio, 2009;Rotab Khan and Darrab, 2010), almost all of the existing CSP-1 models do not consider any interactions with production, inventory and maintenance aspects. An exception is Cao and Subramanian (2013), who provided an analytical framework to evaluate the effects of the CSP-1 design parameters on the Work-In-Progress (WIP) inventory and manufacturing throughput.…”

Standard continuous sampling procedures and tables are conventionally applicable only to continuous production processes that are statistically 'in-control'. Consequently, these standards cannot be used to control quality in deteriorating production processes. Moreover, existing continuous sampling models do not consider interactions with production, inventory and maintenance aspects. In this paper, we attempt to fill these gaps in the literature. We investigate the joint design and optimization of a type-1 continuous sampling plan (CSP-1), make-to-stock production and preventive maintenance of a stochastic production system subject to both quality and reliability deteriorations. Two models of CSP-1 are considered and compared: the classical CSP-1 as in the standard procedures, and a CSP-1 plan with a stopping rule that is combined with condition-based maintenance. For both models, the optimization problem is to minimize the total incurred cost under a constraint on the outgoing quality. A combination of mathematical formulation, simulation and optimization techniques is used to solve such stochastic and constrained problems. Numerical examples are given to illustrate the resolution approach and to highlight some interesting aspects in the interactions between production, inventory, quality, maintenance and reliability. The results obtained demonstrate that sampling inspection plans realize significant cost savings compared to the 100% inspection which is commonly used in the literature of integrated models, and that using the CSP-1 with an inspection stopping rule for deteriorating processes is more costeffective than the classical CSP-1.

“…Neste trabalho, para aferir o desempenho organizacional foram escolhidas as variáveis qualidade e produtividade, próprias do ambiente de manufatura, alvo deste estudo. Medidas de qualidade e produtividade permitem maior generalização e possibilidade de comparação considerando tratar-se de empresas fabris (Shingo, 1996;Paladini, 1990;Lee et al, 2007). Tais medidas relacionam-se à perspectiva de processos internos de Kaplan e Norton (1997).…”

Este estudo teve por objetivo analisar a relação entre atitudes e percepções dos funcionários e o desempenho organizacional, avaliado em termos de qualidade e produtividade, em empresas de manufatura. Como base teórica, assume-se pressupostos da Visão da Empresa Baseada em Recursos (VBR) e discussões sobre Sistemas de Trabalho de Alta Performance (High Performance Working Systems-HPWS) que investigam como variáveis de gestão de pessoas influenciam o desempenho empresarial. Aplicou-se uma survey a 11 empresas de manufatura do sul do Brasil que possuíam práticas de HPWS, com uma amostra de 294 respondentes. As variáveis de percepção e atitude foram submetidas à análise fatorial, sendo que a percepção foi categorizada em três construtos e a atitude em dois. Foram então construídas hipóteses relacionando os construtos das variáveis atitude e percepção com as variáveis qualidade e produtividade. Os resultados evidenciaram que tanto atitudes quanto percepções dos funcionários afetaram a qualidade e a produtividade organizacionais. A percepção negativa do trabalho em relação ao apoio está inversamente relacionada com a produtividade e a atitude de comprometimento com relação à empresa está diretamente correlacionada com a produtividade. Já a percepção negativa do trabalho em relação à pressão está inversamente proporcional à qualidade e à atitude de orgulho com relação à empresa está diretamente correlacionada com a qualidade. Porém, a variância explicada nas regressões foi baixa, o que sugere que outras variáveis influenciam essa relação. De fato, atitudes e percepções influenciam qualidade e produtividade, porém, há que se levar em conta fatores organizacionais como processos e tecnologias adotados pelas empresas, além do próprio efeito direto das HPWS, o que reforça constatações da VBR, mediante as quais o desempenho resulta da articulação de um conjunto de recursos, e não de recursos isoladamente considerados.

“…Due to the emphasis on quality management in recent years, quality has become one of the key performance indicators for many industries (Gerold, 2004). Past research has demonstrated that quality is highly coupled with other quantitative performance factors such as throughput and WIP (Lee et al, 2007). It is necessary to integrate quality modeling into the analysis of manufacturing systems in order to improve both quantitative and qualitative performance simultaneously (Inman et al, 2003).…”

Continuous sampling plans are commonly adopted in various manufacturing industries to improve quality. Quantitative performance measures such as throughput and Work-In-Process (WIP) are highly coupled with quality and are also affected by sampling plans. However, quantitative and qualitative issues have long been studied separately in the literature. This article proposes an integrated quantity and quality model for manufacturing systems with sampling plans. A continuous-time and discrete part flow Markov model is first proposed for a single-stage system. Unlike previous Markov models, this model is capable of calculating various performance measures; e.g., throughput, quality, average fraction of inspection and WIP. A method for performance analysis of twostage systems is presented. The method's satisfactory accuracy is demonstrated with experimental results. Additionally, quantitative analysis is performed to investigate the effect of sampling fraction and clearance number (parameters of a sampling plan) on the various performance measures. Industrial practitioners may benefit in improving the performance by varying sampling plans. Finally, a decomposition model of multistage systems is studied based on which a method to determine the best sampling plans for manufacturing systems is developed. Numerical experimental results demonstrate the effectiveness of the proposed method in finding appropriate sampling parameters for profit improvement.
