With the continual demand for effective manufacturing performance, proper maintenance of production facilities and systems has become the standard of good manufacturing practice. In response, industrial plants, machines, and equipment are becoming more technically advanced, thus more complex and difficult to control and maintained. This paper is focused on a methodology for assigning relative criticality to production equipment in order to optimise a preventative maintenance program. As a case study, the authors examine equipment used in plastic production plants. Generic factors deciding the criticality were considered using a scoring system. With the use of cumulative percentage of scores, an Always Better Control (ABC) analysis was carried out and the critical equipment identified. An effective maintenance programme for the case study shows a 23%reduction of down time and also a 12.7% of equipment durability and about 96% criticality equipment factor, with optimum output. The result of this study will be significant to manufacturing company in minimizing incidences and stoppages not only on critical equipment but production facilities.

Abstract This paper is comprised of three sections and outlines the outcome achieved from instituting an effective preventative maintenance program; specifically, highlighting a steam surface condenser application that was originally equipped with a stainless-steel metal bellows type expansion joint system. In the first section of the paper, a general overview of steam inlet type expansion joint systems will be presented to provide an understanding of the specific application, typical design parameters and conditions, system components, varying expansion joint designs, configurations, and installation methodologies. The second section will outline types of inspections that typically support preventative maintenance programs within the power generation industry. Lastly, the case study will examine the account of an actual project and the practice of implementing a preventative maintenance program; outlining inspection types, how those measures supported a root cause analysis, and ultimately developing a unique solution to address the issues identified during subsequent inspections and analyses. The case study focuses on developing a retrofitted rubber ‘dog bone’ expansion joint system to replace the failed metal bellows expansion joint. Various points within the overall project life cycle will be reviewed; from the point of initial inspection that identified the root cause and defined loss in performance, evaluation and engineering to support the replacement design, onsite execution and installation methodology, and post-maintenance testing and operation.

This paper deals with state of the art risk and resilience calculations for industrial plants. Resilience is a top priority issue on the agenda of societies due to climate change and the all-time demand for human life safety and financial robustness. Industrial plants are highly complex systems containing a considerable number of equipment such as steel storage tanks, pipe rack-piping systems, and other installations. Loss Of Containment (LOC) scenarios triggered by past earthquakes due to failure on critical components were followed by severe repercussions on the community, long recovery times and great economic losses. Hence, facility planners and emergency managers should be aware of possible seismic damages and should have already established recovery plans to maximize the resilience and minimize the losses. Seismic risk assessment is the first step of resilience calculations, as it establishes possible damage scenarios. In order to have an accurate risk analysis, the plant equipment vulnerability must be assessed; this is made feasible either from fragility databases in the literature that refer to customized equipment or through numerical calculations. Two different approaches to fragility assessment will be discussed in this paper: (i) code-based Fragility Curves (FCs); and (ii) fragility curves based on numerical models. A carbon black process plant is used as a case study in order to display the influence of various fragility curve realizations taking their effects on risk and resilience calculations into account. Additionally, a new way of representing the total resilience of industrial installations is proposed. More precisely, all possible scenarios will be endowed with their weighted recovery curves (according to their probability of occurrence) and summed together. The result is a concise graph that can help stakeholders to identify critical plant equipment and make decisions on seismic mitigation strategies for plant safety and efficiency. Finally, possible mitigation strategies, like structural health monitoring and metamaterial-based seismic shields are addressed, in order to show how future developments may enhance plant resilience. The work presented hereafter represents a highly condensed application of the research done during the XP-RESILIENCE project, while more detailed information is available on the project website https://r.unitn.it/en/dicam/xp-resilience.

The Impact

Transformation of digitalization in large industries has an impact on the automation of production equipment, including the replacement of production machines from conventional machines (manual) to digital machines. Meanwhile, automation of production equipment requires workers with higher skills, in fact the existing workforce does not have expertise in carrying out all-digital equipment. The impact is a reduction in labor (layoffs). Machine replacement is done in stages so that the reduction of workforce (PHK) in bulk is not visible. However, the inconsistency between the preparation in the world of education and the needs in the world of work continues to occur today. Until now, vocational development based on local resources has not been operating optimally and needs serious attention from the local government. The government on various occasions mentioned four leading sectors that will be strengthened in the development of vocational institutions, namely maritime, tourism, agriculture (food security), and the creative industry. In addition, the government is also developing a policy scheme for Skill Development Funds (SDF), which is a skills improvement program for workers affected by automation (PHK), including through Vocational Training Center (BLK).

However, data on the characteristics of crafts are not yet available comprehensively. This study aims to explore the characteristics of Gorontalo water hyacinth craft to uncover the potential and problems. The study used qualitative methods of case study models. The data were collected through observation, interviews, testing, and literature study. Data were analyzed interactively through selection and coding, categorization, data display and discussion, and conclusions. The results showed that Gorontalo water hyacinth craft has characteristics in aspects: crafters, production technology, products, and distribution that reflect the potential and problems. The characteristics of the crafters are experts in production skills but weak in design innovation. The characteristic of production technology is the potential in the availability of raw materials and systematic work methods. However, it is problematic in the modernization of production equipment and the division of labor. A characteristic in terms of products is its potential in product diversity but problems in standardizing size and ergonomics. The characteristics of the distribution aspect include the potential in marketing products in various ways but problems in the promotion and improvement of the social image of the product. This finding can be used as a reference to formulating the concept of developing Gorontalo water hyacinth craft appropriately or other similar crafts.

Purpose The ability to operate global distribution channels of products is commonly considered a critical determinant of a manufacturer’s competitiveness. Nowadays, many products are often complemented with value-added services challenging the efficacy of the status quo of distribution channels. Investigating this rather new phenomenon, the purpose of this paper is to provide an initial understanding of the implications of servitization for manufacturers’ global business-to-business (B2B) distribution. Design/methodology/approach The aim is to elaborate service-dominant logic (SDL) in the context of global B2B distribution. The study builds on case study data collected from a medium-sized European manufacturing company offering production equipment and solutions, and three of its global distributors. Findings The results indicate that the co-producing customer value, the increasing role of operant resources of both a distributor and a manufacturer, and triadic co-creation between a manufacturer, a distributor and an end customer have increasing importance in the indirect distribution network. Research limitations/implications Data are limited to data collected from a single in-depth case study. The results of this study should be investigated by collecting more data in a broader context in the form of surveys. Practical implications Several guidelines related to global distribution are developed for managers, and current distributor selection criteria are completed to meet the needs of this servitization approach. Originality/value Empirical research on servitizing manufacturers with global B2B distribution is scarce. This paper employs SDL to provide an in-depth understanding of the implications of servitization for distribution.

Purpose – The purpose of this paper is to uncover the significance of quick changeovers in the packaging line of a pharmaceutical company. Using an integration of different lean practices, the study aims to reduce the batch change and changeover time up to 50 per cent, increasing overall equipment effectiveness by 25 per cent. Design/methodology/approach – The paper gives setup instructions and guidelines for preparing the standardized setup procedure without ignoring the actual constraints in a pharmaceutical company. It uses a case study to generate an integrated setup reduction approach, utilizing single-minute exchange of die tools (SMED) in combination with suppliers, inputs, process, outputs and customers (SIPOC), Kanban, 5S techniques and Total Productive Maintenance (TPM) indexes to achieve faster setups. Findings – The SMED approach helps the pharmaceutical company to eliminate unwanted activities and to externalize and reduce the internal activities by simplification or standardization. The application of other tools, such as 5S and Kanban tool-kits, allowed the company to optimize the process and reduce the standard deviation of the changeover times. Good manufacturing practice (GMP) procedures of the pharmaceutical sector limit the conversion of internal setup elements to external setup elements. Originality/value – The paper demonstrates the practical application of SMED, showing how it can bring real breakthroughs in productivity to a pharmaceutical company. Moreover, in this work, we highlight the importance of an integration of different lean practices to reduce variation in the changeover time. In particular, the standardization of setup tasks and the increased reliability in the material supply chain, in addition to reducing the changeover mean time can also reduce the standard deviation of the setup process time.
