A variety of order release mechanisms have been developed for workload control. In this paper the effectiveness of order release mechanisms in a job shop environment is assessed by studying the influence of single order release dimensions, instead of comparing different mechanisms as a whole. In particular, the paper aims at improving the basis for selecting the workload accounting over time and the workload control strategies, through the understanding of its impact on the overall system performance. The robustness of these order release strategies to environmental perturbations is also assessed through a plan of experiments based on the Taguchi method. Simulation results provide important insights for the implementation of order release mechanisms.
POLCA (i.e. Paired-cell Overlapping Loops of Cards with Authorization) is a card-based decision support system for production control, developed to support the adoption of Quick Response Manufacturing. Two variants of POLCA have been proposed in the literature to improve POLCA performance: Load Based POLCA and Generic POLCA. In this paper, we combine these two variants into a single production control system and analyse its performance for different backlog-sequencing rules. The results of a simulation study carried out for a make-to-order flow shop, support the strategy of combining these two POLCA variants and show that capacity-slack backlog sequencing based on corrected aggregate load have the potential for improving performance.
O Diagnóstico para a Sustentabilidade do Concelho de Castelo Branco tem dois grandes objectivos: - Apresentar um diagnóstico do Concelho, simples e acessível; - Apontar para as Áreas Estratégicas, em que assentará Castelo Branco Agenda XXI, posteriormente validadas pela comunidade/actores locais. Tem como propósito abranger e integrar num mesmo documento uma descrição actual e representativa dos sistemas ambientais, sociais, económicos e institucionais do concelho de Castelo Branco, resultando na identificação das suas potencialidades e fragilidades. Deste modo, obtém-se a definição das oportunidades e ameaças do concelho, de forma a assentar as grandes opções estratégicas do Desenvolvimento Sustentável, através de um modelo – Castelo Branco Agenda XXI. Assim, o Diagnóstico para a Sustentabilidade permite avaliar a realidade concelhia e efectuar uma análise prospectiva, nomeadamente no que respeita à identificação de problemas e oportunidades, em consonância com o já planeado pela CMCB, no sentido do Desenvolvimento Sustentável e da melhoria da qualidade de vida.
