This study focuses on management ways within a city multi-floor manufacturing cluster (MFMC). The application of MFMC in megapolises is closely related to the problem of urban spatial development and the problem of matching transport and logistics services. The operation of the MFMC depends on the efficiency of production and transport management considering technical, economic, end environmental factors. Therefore, conditions affecting decision-making in the field of production planning by MFMCs and accompanying transports within the agglomeration area with the use of the production-service platform were presented. Assumptions were created for the decision model, allowing for the selection of partners within the MFMC to execute the production order. A simplified decision model using the Hungarian algorithm was proposed, which was verified with the use of test data. The model is universal for material flow analysis and is an assessments basis for smart sustainable supply chain decision-making and planning. Despite the narrowing of the scope of the analysis and the simplifications applied, the presented model using the Hungarian algorithm demonstrated its potential to solve the problem of partner selection for the execution of the contract by MFMC.

According to the estimate of the EU Commission 85 percent of criminal investigations require electronic evidence, while in almost two thirds (65 percent) of the investigations where e-evidence is relevant. Investigation and prosecution of crime increasingly relies on the possibility to have access to data held by service providers, as private company. Modern criminal investigation and use of electronic evidence imposes challenges to the right to fair trial and rule of law standards. The paper identifies benefits and challenges of proposed EU instruments for facilitating e-evidence. The European Commission proposed Regulation of Production Order and Preservation Order with the aim to facilitate access to relevant data stored by service providers. The paper recognizes shortcomings of the proposed Regulation. The biggest challenge is lack of judicial oversight of orders, as a guarantee of fair trial. The paper includes recommendations and policy options for promoting judicial system for cross border access and collection of electronic data in line with EU fundamental rights standards.

This empirical study deals with integration of Analytical Hierarchy Process (AHP) with multi-item inventory management using Part-Period Algorithm. Among many variables which affects inventory systems, this study considers the variables of lot-sizing rules, sequencing, demand pattern, coefficient of variations, and change over cost. AHP is used to pick a sequencing rule and performance criteria. This study describes the application of AHP methodology in the form of multiple tables that will assist production managers in a Group Technology environment, to minimize employee and machine idleness. It will help managers make decisions on production order quantity, the sequence in which jobs should enter work centers, and in the determination of uniform production cycle times.

AbstractThe Cyber-Physical Production System (CPPS) is a concept derived from software (cyber) and hardware (physical) applications and is based on global information exchange between such systems. The CPPS is known as a trend of Industry 4.0 (I4.0) focusing on flexibility regarding new products and adaptability to new requirements. This paper focuses on two I4.0 scenarios described by the Platform Industrie 4.0 that describe challenges for the industry towards its digital future. First, it looks at the Order Controlled Production (OCP) scenario that deals with flexible and self-configuring production networks. It describes the dynamic organization of production resources required to execute a production order. Second, the Adaptable Factory (AF) application scenario is discussed, which focuses on the configuration of production resources and describes the adaptability of an individual facility through (physical) modification. This paper first provides a detailed analysis of the requirements from these scenarios. Furthermore, it analyses the current Multi-Agent System (MAS) architectures and agent-based planning and decision support systems requirements. MAS can be used to create application-independent I4.0 systems with arbitrary hardware automation platforms. To create a scalable communication network that also supports application independence and enables the semantically machine-readable description of the exchanged data, the OPC UA standard was adopted. As a result of the study, the concept shows how different and independent automation platforms can be seamlessly connected via OPC UA. The proposed MAS concept has been evaluated in different use cases, namely OCP and AF.

Industry 4.0 defines the fourth industrial revolution, a new level in the organization and management of products and production systems. This cycle consists of services that include the entire chain, including individualized customer requests, product development, production order, distribution, and recycling to the end user. One of the most important preconditions for the realization of the Industry 4.0 revolution is that companies have completed their digital transformations. New technologies and digitalization have brought a new understanding of insurance. Insurance companies are focused on four areas such as big data, artificial intelligence, internet of objects, and blockchain in the changing world. With the changing habits of consumers in their daily lives, new generation insurance needs emerged. The introduction of a new era shaped by the insurance industry with new products, services, competitors, and customer expectations will have various effects. This chapter describes how Industry 4.0 transforms the insurance sector.

Introduction: CV. X merupakan perusahaan roti Wholesaler yang memegang lisensi CJ Culinary Concept Holding dan memiliki 3 gerai (outlet) di Surabaya. Masalah yang dihadapi oleh CV. X adalah terdapatnya selisih saldo persediaan antara pencatatan dan fisik sebesar 25%. Selain itu, masalah-masalah lain yang ada dalam perusahaan adalah hilangnya bahan baku, penyusutan bahan baku segar, rusaknya adonan, sistem handling, dan keterlambatan pengiriman produk jadi ke outlet. Sistem pengendalian aktifitas dengan menggunakan pendekatan rantai nilai produksi merupakan sebuah metode yang dapat diaplikasikan untuk merancang sistem pengendalian pada setiap tahapan dalam proses produksi.Methods: Penelitian ini menggunakan metode kualitatif eksploratori untuk menganalisis sistem pengendalian yang telah diterapkan perusahaan.Results: Hasil penelitian menunjukkan bahwa masalah seperti kehilangan bahan baku dan penyusutan bahan baku segar dapat dikendalikan dengan menggunakan sistem pengendalian aktifitas yang menerapkan 3 bentuk dari pengendalian atas tindakan (Behavioral constraints, Preaction reviews, dan Action accountability) dan 3 metode dalam pengendalian personalia ( Selection and placement, Training, dan Job Design and provision of necessary resources). Kedua, adonan yang rusak dalam proses pengolahan dapat diatasi dengan mengubah sistem produksi yang manual menjadi komputerisasi. Ketiga, permasalahan dalam proses distribusi yatu sistem handling dan keterlambatan pengiriman produk jadi ke outlet dapat dikurangi dengan menciptakan sebuah proses produksi yang terintegrasi yang dapat tercermin dari Laporan Produksi per batch. Terakhir, ketidaktersediaan bahan baku di Gudang dan keterlambatan pengiriman bahan baku impor dapat diselesaikan dengan sistem persediaan yang pembeliannya dipicu oleh Order Produksi. Conclusion and suggestion: CV. X perlu menggunakan sistem pengendalian aktifitas dalam rantai nilai produksi untuk mengendalikan biaya bahan baku dan penelitian selanjutnya mengenai sistem Point of Sales (POS) dan Production Order (PO) perlu dilakukan.

Translation is never completely neutral. On the contrary, it can be used in a double ideological-social sense: to orient people toward unaware, passive acceptance of a given situation or, instead, to evidence the possibility of change. On this account, most interesting are observations made by Marcuse. He analyzes a study conducted on work conditions in a firm in the United States, evidencing how complaints originally formulated by workers as general statements about a common condition lose their “generality” when “translated”: The actual meaning of their statements changes in the “translation.” The tones of protest in accusations denouncing bad work conditions for all are reduced to the status of isolated complaints concerning the life of single individuals. Similar situations abound in social practice and translation today, in the global “communication-production” order where language usage anaesthetizes critical awareness and the common sense of responsibility. This chapter investigates the relationship between words and values, the ideological dimension of sense, and translation, whether intralingual, interlingual, or intersemiotic, either to favor passive compliance to the order of discourse, the condition of “linguistic alienation,” or to develop the capacity for interrogation and conscious awareness in a world, today’s, that, like Orwell’s, resorts to a sort of Newspeak to obtain consensus and assent to the order of discourse, the official order.

Competition among small and medium-sized enterprises has grown over the years due to the advancement of technology and the globalization of the market and operations. Production Planning, Programming and Control (PPCP) acts as a link between management and manufacturing, in these small and medium-sized enterprises. The present study, through an action research in a microenterprise manufacturer of Brooms made of PET, aimed at the implementation of a hybrid PPCP system. The model was proposed by using the concepts of Lean Manufacturing, to map and know the process eliminating wasted time and resources, Theory of Constraints to identify constraints and bottlenecks and the MRP system to act within the context of pushed production. Therefore, it is possible to obtain a Framework that presents the method used in the implementation of the work, which provided with results such as production order, security stock, and correct input definition. The model put the company in other level of organization and efficiency in the use of resources.

The review is devoted to two important quantities characterizing many-body systems, order indices and the measure of entanglement production. Order indices describe the type of order distinguishing statistical systems. Contrary to the order parameters characterizing systems in the thermodynamic limit and describing long-range order, the order indices are applicable to finite systems and classify all types of orders, including long-range, mid-range, and short-range orders. The measure of entanglement production quantifies the amount of entanglement produced in a many-partite system by a quantum operation. Despite that the notions of order indices and entanglement production seem to be quite different, there is an intimate relation between them, which is emphasized in the review.

The European Investigation Order (EIO) was supposed to offer a comprehensive solution to cross-border gathering of evidence within the area of freedom, security and justice replacing a patchwork of instruments and providing for one single standardised order for all types of evidence. However, not even a year since the deadline for its implementation had passed, the Commission proposed an instrument that would be applicable for electronic evidence: European Production Order (EPO). This initiative was born from an increasing frustration in gathering this type of evidence and the conviction that the EIO is not suitable for that purpose. The need for digital evidence (according to the estimate of the EU Commission, 85% of criminal investigations require electronic evidence) is a direct consequence of the place information and communication technology has taken in everyday life. However, electronic evidence differs in a number of ways from ‘real-life’ evidence rendering current legal framework extremely impractical for law enforcement. One of the major obstacles that law enforcement authorities encounter is the fact that the data they need are often stored abroad or by a foreign service provider. Both instruments were conceived because of the need to gather evidence across borders; however, the transnational component is different (evidence being abroad vs. service provider being foreign). Both instruments subject ‘European citizens to the investigative machinery of any other Member State’, however, in a different way. If the e-evidence package is adopted, it will create a dual system of cross-border gathering of evidence, with different philosophy, procedure, enforcement and protective framework. The goal of this article is to analyse and compare two different models of acquiring evidence that these two instruments offer as well as to delimitate their (non-exclusive) scope. The concluding part will provide a reflection on the systemic consequences of this duality of instruments and of introducing the EPO model in particular.
