- ArtigoAllocation of Improvement Strategies in a Flow Shop with Two Capacity Constrained Resources(2020-07-05) Marcel Utiyama; CORREIA, FERNANDA CAVEIRO; Dario AlliprandiniThe main goal of this paper is to identify the best strategy to allocate improvement programs in a flow shop with two capacity constrained resources. We collected data from a manufacturing company, and we used them to conduct a simulation with the System Dynamics-Factory Physics model. The main variables considered were the mean time between failures and the mean time to repair, and lead time was the output. Strategies used are mainly focused, distributed, and hybrid. Findings show the effect of the allocation of different improvement strategies on lead time reduction. We indicated that for the flow shop analyzed the focused strategies delivered the best results. When it is not possible to perform a large investment in the capacity-constrained resource, companies should use hybrid approaches. An important contribution is a hybrid approach, which is a new way of directing efforts of improvements. Results showed that both strategies, hybrid time to repair improvement and hybrid time between failures improvement, delivered better results compared to the respective distributed strategies.
- ArtigoThe impact of product variety on fill rate, inventory and sales performance in the consumer goods industry(2020-03-05) SANTOS, VICTOR; Sampaio, Mauro; Dario AlliprandiniThe impact of product variety decisions on fill rate, inventory and sales performance in a consumer goods company has been examined. From a marketing perspective, it is possible to leverage sales, reach new segments and consequently increase competitiveness when there is a greater product variety on the market. However, operations and logistics professionals indicate potential impacts on the supply chain, such as production, storage and distribution complexity. The nature of the product variety-cost-sales performance relationship is not clear, and empirical evidence about whether and how operations cost and sales performance increases with variety is inconclusive. Design/methodology/approach – The multiple linear regression and the Tobit regression techniques were applied over a seven-year horizon of data from a business intelligence platform of a consumer goods company. Findings – Our results show that sales performance is negatively associated with product variety. The total effect of product variety on sales performance has been examined, including both the direct effect and the indirect effect through inventory and fill rate. Therefore, the findings provide a comprehensive understanding of the impact of product variety on operations and sales performance. Originality/value – Several studies have researched the impact of product variety on fill rate, inventory and sales performance separately; however, the research of the impact and the relationship of these factors is scarce and limited.
- ArtigoEnvironmental assessment in the conceptual design phase of new product development(2020-02-14) RUY, MARCELO; Dario Alliprandini; Gabriela ScurMany studies have shown the importance of incorporating environmental issues into the process of new product development (NPD). However, a critical review of the literature reveals a lack of tools to evaluate environmental criteria during the initial phases of product design - specifically, the conceptual design phase and concept selection stage. The objective of this manuscript is to present a framework for the environmental evaluation of product concepts based on design for environment (DfE), with an emphasis on tangible products. The framework could enhance the effectiveness of implementing DfE strategies in the conceptual design phase. The framework was based on DfE strategies related to the physical dimension of products and the analytical hierarchy process (AHP). This is one of the very first studies to present a framework for selecting a concept that best meets DfE criteria from a product life cycle perspective and offers the potential to be expanded to multiple manufacturers.
- ArtigoRelationship between continuous improvement and innovation performance: an empirical study in Brazilian manufacturing companies(2019-08-16) LIZARELLI, FABIANE LETÍCIA; TOLEDO, JOSÉ CARLOS; ALLIPRANDINI, DÁRIO HENRIQUEThe continuous improvement programs and innovation have been stimulated and widely deployed due to the importance to the competitiveness of the organisations, being subjects of interest in several studies. However, there are few researches on the relationship between continuous improvement programs, such as Lean, Six Sigma and Lean Six Sigma, and the innovation performance. The objective of the paper is to analyse the relationship between continuous improvement on the performance of product and process innovation, both incremental and radical, aiming at comparing the results of these relationships considering the use of the different continuous improvement programs mentioned above. To improve the analysis, the continuous improvement practices were divided into four subconstructs – culture, people, strategy and top management. A web survey was applied in Brazilian manufacturing companies that carry out product or process innovations and have continuous improvement initiatives implemented. The results demonstrate that continuous improvement has positive and statistically significant relationships with the four types of innovation performance and the results remain independent of the continuous improvement program that the company applies. Besides, the use of continuous improvement practices is more relevant to innovation performance than specific programs of improvement such as Lean, Six Sigma or lean Six Sigma.
- ArtigoPlanning and organization of road port access: The case of the Port of Santos(2019-09-10) SANTOS, Murillo Caldeira dos; Wilson de Castro HilsdorfApproximately 90% of the cargo in the world is carried via maritime transport, making ports akey focus for international trade and transforming port installations into constant objects ofacademic study. One of the key aspects of port management is the issue of access. With anincrease in cargo volumes, many port cities have experienced constant bottlenecks due to the lackof adequate space for port operations. Considering that the terrestrial access problem faced byPort of Santos has not yet been analyzed, this research aims to evaluate the logistical and en-vironmental effectiveness of the organizational method adopted in Santos to address this pro-blem, having as reference the solutions adopted by ports in developed countries. The organiza-tion method of terrestrial access adopted in Santos proved to be an effective alternative from alogistics operation perspective with the implementation of the regulating yard. On the otherhand, the condition of a port of an emerging country strongly influence the approaches taken toaddress environmental issues, where cultural and economic issues hamper the adoption ofmeasures to reduce harmful emissions in Santos.
