Opis:
The Complexity Index method is an approach developed to help manufacturing companies quantify complexity in production. This paper sheds light on the connection between complexity and manufacturing problems and how the Complexity Index method was used to capture the areas in a production line with high levels of complexity to determine the sources of manufacturing problems related to labour time, surplus production, and manufacturing error. The main areas perceived as complex were due to Work Instructions, Work Content, and Product Variants. The perceived complexities were assessed for proper actions to be taken to decrease their level of complexity. The correlations between complexity and manufacturing problems were used for tracking related issues and ways for improvement. This study presents data on the use of workers’ perception to uncover the areas of complexity, which could be used by the management team to pragmatically capture difficulties and issues related to manufacturing problems to improve the production system.

Opis:
Performance measurement system in supply chain management (SCM) has been receiving increasing attention by business organizations as a way to evaluate efficiency in supply chain activities. Assessing the performance of supply chain uncovers the gap between planning and actual performance as to trace the potential problems thus ascertain necessary areas for improvement. This research aims to investigate the application of performance measurement system in SCM as well as exploring its relationship with organization’s performance among Malaysian manufacturing firms. By utilizing the questionnaire method, respondents involved were requested to indicate the extent to which they use a number of 24 selected performance measures that are related to SCM. The results show that the majority of the observed manufacturing firms utilize specific performance measurement tools in evaluating the supply chain performance. The current performance measurement techniques, the Balanced Score Card is adopted by around a quarter of the total responding firms followed by Supply Chain Operations References Model – SCOR, which attracts total users of only a fifth of the total respondents. In particular, performance measures under customer service category recorded the highest number of usage followed by cost-based performance measures and operations management. The results of this investigation also unveil few major points that are important to be highlighted. Firstly, the obtained outcomes of this study bring to light the significant relationships between the utilization of supply chain performance measures under customer service, operations management and organizational performance. In addition, this study discovered a significant correlation between the size of the organization and the extent of use of supply chain performance measures and how these two variables positively correlated. Lastly, the findings also suggested that the performance measures for SCM has been playing a crucial role in enhancing the performance of the organizations and is increasingly operated as the firms grow in size. Based on the brief highlighted points listed above, it is not an exaggeration to say that this research contributes new information to the body of knowledge in performance measurement system in SCM and its associations with organizational performance.

Opis:
The objective of this study is to identify the contribution of the lean supply chain (LSC) to manufacturing firms in the Kingdom of Saudi Arabia (KSA). Out of the population of the study, 150 firms were selected from the Al-Qassim region to encompass the sample of the study. Four variables include waste elimination, cost reduction, manufacture–supplier relationship, and manufacture–customer relationships were constructed as predictors of productivity. A questionnaire-based survey was conducted to collect the study variables. A total of 75 questionnaires were distributed in the sample, of which 69 were returned. All of them were valid for the statistical analysis. The results of the study confirmed the hypotheses that the constructed predictors could predict the productivity of the manufacturing firms in the Al-Qassim region. That is, there were statistically significant impacts of LSC dimensions on the productivity. The study contributes to the body of supply chain (SC) literature by providing evidence on the positive impact of LSC on productivity in an Arabian context, particularly in KSA. However, the study was conducted in one industrial region in the KSA, therefore the generalization of the findings may not be applicable to other firms in the same country or other countries.
Artykuł przedstawia wpływ wyszczuplenia łańcuchów dostaw w regionie Al-Qassim na produktywność. Dla celów badawczych przyjęto cztery zmienne: usuwanie odpadów, redukcję kosztów, relację producenci-dostawcy oraz relację producenci-klienci. Badaniem objęto 69 firm i poddano je analizie statystycznej. Otrzymane wyniki potwierdziły sformułowaną przez autorów hipotezę. Oznacza to, że występuje znaczący wpływ stopnia, w jakim zastosowano wyszczuplenia łańcuchów dostaw na produktywność. Badanie stanowi przyczynek do dalszych badań w tym obszarze.

Opis:
Paracetamol also known as acetaminophen is a widely used antipyretic and analgesic agent. The therapeutic efficacy of pharmaceutical products depends on both microbial and physicochemical qualities of the products, hence, the need to routinely assess the pharmaceutical quality of the available brands of the tablets to ensure they conform to standard specifications. This study was done to evaluate the microbial and physicochemical qualities of 10 brands of paracetamol tablets sold in Nigeria. The purchased drug samples were evaluated for their uniformity of weight, crushing strength, friability, disintegration time, total viable aerobic count and content of active ingredient. These tests were performed by standard methods and techniques following official pharmacopoeia protocols. The investigated 10 brands of paracetamol tablets passed the standards of the British Pharmacopoea (BP) regarding microbial specifications. The tablets were uniform in weight with crushing strength 5 KgF - 12 KgF except a brand with crushing strength ranging between 15 KgF – 18 KgF and another brand which has no crushing strength. The disintegration times were within 15 minutes except a brand with a disintegration time of 27 minutes 44 seconds. Friability values were less than 1%. The % content of paracetamol as an active ingredient in the tablets ranges from 90-110%. 8 out of 10 brands of the paracetamol tablets assessed met all compendia standards. However, products of good quality can be guaranteed through quality control and adherence to the provisions of good manufacturing practices. Also, a routine sentinel market surveillance of pharmaceutical products is encouraged.

Reverse engineering (RE) aims at the reproduction of products following a detailed examination of their construction or composition. Nowadays, industrial applications of RE were boosted by combining it with additive manufacturing. Printing of reverse-engineered elements has become an option particularly when spare parts are needed. In this paper, a case study was presented that explains how such an approach can be implemented in the case of products with asymmetric mechanical properties and using replacement materials. In this case study, a reverse engineering application was conducted on a textile machine spare part. To this end, the nearest material was selected to the actual material selection and some mechanical tests were made to validate it. Next, a replacement part was designed by following the asymmetric push-in pull-out characteristic. Finally, the finite element analysis with Additive Manufacturing was combined and validated experimentally.

Present economic situation in the EU after the crisis of 2008–2010, escalating protectionism among EU Member States, voices in favour of reindustrialization of the EU economy in a traditional style of the 1970s and the 1980s, and the British leadership in services and new business models are the most important challenges for the future development of the EU Internal Market, as well as for the EU economy, as a whole. Therefore, the aim of the paper is to evaluate changes in the structure of the EU economy and intra EU trade in the context of Brexit. To this end, we will analyse changes in values and shares of selected sectors directly linked to the EU Internal Market in value added and intra EU trade in 2010–2014. Moreover, in order to grasp potential consequences of Brexit, we will compare data for the EU-28 and the EU-27 (without the UK). Our research allows us to conclude that Brexit may result in reduced supply of innovative and business services with the highest added value in favour of higher shares of regular manufacturing sectors within the internal market of the EU (both in value added and intra EU-27 trade). Therefore, after the UK leaves, the EU-27 will lose its competitiveness and a strong position in intra EU trade vis-à-vis third countries.

Opis:
This paper presents the results of experimental research regarding the determination of the flow characteristics of the compressor of an automotive turbocharger with a plastic rotor disc. The disc was manufactured using the 3D printing technology called the multijet printing, which allows complex geometries to be printed with high precision. Currently, in addition to speeding up the manufacturing processes and reducing their costs, 3D printing technologies are increasingly seen as standard tools that can be used in the design and optimization of machine parts. This article is a continuation of research on the possibility of applying additively manufactured elements in turbomachines. The experimental research was carried out at high rotational speeds (up to 110 000 rpm), using the automotive turbocharger with two different compressor rotors (i.e. one aluminum and one polymer). The first chapters of the paper discuss the preparation stage of the research (i.e. the manufacture of the rotor, the test rig). Then, the experimental research and the flow characteristics are described. The results obtained for the two types of discs were compared with each other and the area of application of the additively manufactured rotor was determined. The rotor functioned properly in the range of tested operating parameters and the results obtained showed that the technology and material applied could be used in the optimization studies of the blade systems of high-speed fluid-flow machines.
