Originality This is the first research article which uses the queuing theory to find the best place of the Order Penetration Point (OPP) in a production line with impatient customers. Research method Two scenarios are studied in this paper. 1- Semi-finished products are produced and stored in a buffer. No semi-finished product will be completed until a specific order comes to the system. This strategy leads to idle cost, but there is savings obtained in terms of eliminating investment in finished goods inventory and its holding cost. We can calculate the total cost of the system and find the optimal machine for the buffer of semi-finished products. 2- We use both MTS and MTO for completing the semi-finished products. When there is no customer in the system, semi-finished products are completed based on the MTS strategy and finished products are sent to a warehouse. But, when an order comes in for customization, a semi-finished product get assigned to that order and after finishing the current MTS job on each machine, this MTO job starts to complete the semi-finished product. To calculate system performance indexes, we use the Matrix Geometric Method (MGM) after modeling the systems with queuing theory concepts. Main findings Numerical examples show the convexity of total cost in terms of product completion percentage and number of customization lines after the OPP. Also, increasing the production rate leads to higher expected number of semi-finished products in the buffer. Implications for theory and practice Positioning OPP in manufacturing systems to compare different production strategies (MTS/MTO) has not been widely studied yet. This paper shows how manufacturing companies can apply the OPP to obtain benefits from both MTS and MTO strategies according to various cost parameters of the production lines. Using queuing theory concepts to model the problem under study helps to consider the external factors such as impatient customers and demand arrival uncertainty that can affect the performance measures of the system besides the internal factors such as production rate and inventory related costs. The idea of expanding the production line after a specific station and have more customization lines to improve customer satisfaction is studied in this paper as well. <![CDATA[A model-based Decision Support System for multiple container terminals hub management]]> Abstract Paper aims To develop a model-based Decision Support System (DSS) that allows identifying the best strategy of the inter-/intra-terminal flows of the containers in order to increasing the performance of the hub under economic and environmental perspective. Originality The adoption of a dry port can effectively solve the congestion problem of a terminal only if an integrated sustainable solution (dry port location and container strategy storage) is identified. Research method The model is based on a heuristic computational algorithm for non-linear programming. Main findings The application of DSS to a full-scale numerical case show the model capabilities in identifying the optimal logistic strategies ensuring a low CF and in optimizing the cost due to transport activities. Implications for theory and practice It is possible to identify different strategies allowing to obtain an eco-friendly solution reducing, at same time, the costs for a given number of containers to be handled. <![CDATA[Technological game changers: convergence, hype, and evolving supply chain design]]> Abstract Paper aims Poor supply chain design cost Boeing, Chipotle, Lego, and Toyota billions in revenues, capitalization, and reputational value.

Originality This heuristic modifies Haessler’s sequential heuristic procedure (1975) by adapting the Integer Bounded Knapsack Problem to generate cutting patterns, instead of the original lexicographic search employed. The solution strategy is to generate different cutting plans using MSHP, and then to use an integer programming model to seek even better results. Research method It is a axiomatic research, ordinary in studies of Operational Research. Main findings In the computational experiments, we demonstrate the effectiveness of the algorithm with two sets of benchmark instances by comparing it with other approaches, and obtaining better solutions for some scenarios. Implications for theory and practice The approach is suitable for practitioners from different industrial settings due to its easily coding and possible adaptation for problem extensions. <![CDATA[Statistical Thinking in quality improvement: use, difficulties and benefits of its implantation in industries of the Brazilian State of São Paulo]]> Abstract Paper aims Identify the use of statistical thinking and techniques and their main difficulties and benefits in the Brazilian State of São Paulo industries. Originality There are few empirical studies on the application of the statistical thinking and techniques which study their difficulties of implementation and their benefits in manufacturing companies. Research method A web survey of a sample of 243 manufacturing companies. Main findings The companies, in general, use some statistical principles and basic techniques for process control and improvement, however, companies that use principles and techniques more consistently have greater operational and team benefits. The main difficulties are associated to lack of culture and knowledge. Implications for theory and practice The statistical application enables effective processes improvements and it is associated with motivation for further improvements, consolidation of improvement programs and culture of quality. This finding suggests managerial implications such as to plan actions to deploy and disseminate the culture of statistical thinking in an evolutionary way, training and support for use and to overcome barriers. <![CDATA[The impact of the fourth industrial revolution: a cross-country/region comparison]]> Abstract The fourth industrial revolution stimulates the advances of science and technology, in which the Internet of Things (IoT) and its supporting technologies serve as backbones for Cyber-Physical Systems (CPS) and smart machines are used as the promoters to optimize production chains. Such advancement goes beyond the organizational and territorial boundaries, comprising agility, intelligence, and networking. This scenario triggers governmental efforts that aim at defining guidelines and standards. The speed and complexity of the transition to the new digitalization era in a globalized environment, however, does not yet allow a common and coordinated understanding of the impacts of the actions undertaken in different countries and regions. The aim of this paper, therefore, is to bridge this gap through a systematic literature review that identifies the most influential public policies and evaluates their existing differences. This cross-country/region comparison provides a worldwide panorama of public policies' durations, main objectives, available funding, areas for action, focused manufacturing sectors, and prioritized technologies. Findings of this review can be used as the basis to analyse the position of a country against the existing challenges imposed towards its own industrial infrastructure and also to coordinate its public policies. <![CDATA[Application of lean healthcare in hospital services: a review of the literature (2007 to 2017)]]> Abstract Paper aims The demand for quality health services is increasing and the efficiency in hospitals is related to the continued improvement in their processes and services.
