The multiproduct production system has been applied extensively in factories worldwide due to the diverse consumption habits of consumers. However, current Overall Equipment Effectiveness (OEE) measurement methods are not suitable for it properly. With the prevailing of multiproduct production system, it is essential to measure the effectiveness accurately in this kind of production system. In order to fill this gap, based on analyzing former OEE models, we propose the multiproduct production system effectiveness (MPSE), including the calculating steps and application framework, in this paper using the heuristic method. This MPSE is verified by a case study. The principal results show that the proposed MPSE can significantly enhance overall production effectiveness and improve the measurement of indicators in the multiproduct production system, which enriches the theory of OEE at the theoretical level and proposes a novel way to measure and improve the effectiveness of the multiproduct production system effectively at the practical level.

Abstract In this paper, I discuss critically the traditional view of reanalysis, taking into account recent debates about the concept. In particular, I argue that the debate about reanalysis tends to conflate two interpretations of reanalysis: reanalysis as a type of language change among other ones, and reanalysis as the recognition or “ratification” of any kind of change. I offer a possible explanation of that potential confusion. I then illustrate this distinction using the history of the French est-ce que question as a case study. I report original diachronic research on the history of that construction. Further, I discuss implications both at a conceptual-theoretical level and at a practical level for further diachronic research. The paper concludes with a summary and discussion of the findings.

Abstract This article makes the case for viewing international organisations (IOs) as global polyarchies. Our argument is twofold: on a theoretical level, IOs often meet the criterion of philosophical coherence, as they are based on rules of membership and decision-making that are compatible with those found in democratic institutions. On a practical level, we believe the concerns of IOs about pluralism, inclusiveness and efficacy go far beyond rhetoric, and may decisively influence their activities as well as their outcomes. To this end, the first section explores Robert Dahl’s concept of polyarchy and applies this to global institutions. In the subsequent sections, we advance our empirical argument with the UN as a case study. We reach three main conclusions. The first is that, at the bureaucratic level, the UN Secretariat performs some typically democratic functions, such as multilateral representation and the constitution of international regimes, which turns it into an important channel for feasible democracy in international politics. Second, at the multilateral level, the UN General Assembly (UNGA) represents a specific kind of representative polyarchy by allowing the greatest possible number of countries to have an equal say in global affairs. And third, it also serves as a gateway for multilevelled international representation by including a diversity of non-state actors in what has been called the ‘Third United Nations.’

Abstract: The rapid development of the number of islamic banks should be balanced with the availability of infrastructure to carry out daily operational practices. The operational tools include hardware as like as representative office, computerized system, reliable human resources and software as like as method, culture and financial and islamic banking knowledge. In terms of development of Islamic finance is the paper "Alternative Calculation of Return Shahibul Mal on Mudharabah Scheme on Bank Syariah" was written. During this calculation of return shahibul mal has not been standardized in a formula, thus causing two serious effects. First, in the theoretical level, the formula has not yet created a difficulty. Secondly, in practical level, the formula is not impressive enough to recalculate the complexity of return calculations obtained by shahibul mall, causing laziness of the community using the services of islamic bank. This paper using mathematical and arithmetic equations with the help of modeling made by the author to refine and improve the method of calculation that has been available. The purpose of this paper is to create a standard formula that facilitates the calculation of return earned by a shahibul mal in a mudaraba scheme in a islamic bank.

This paper discusses a digital twin-based approach for designing and redesigning flexible assembly systems. The digital twin allows modeling the parameters of the production system at different levels including assembly process, production station, and line level. The approach allows dynamically updating the digital twin in runtime, synthesizing data from multiple 2D–3D sensors in order to have up-to-date information about the actual production process. The model integrates both geometrical information and semantics. The model is used in combination with an artificial intelligence logic in order to derive alternative configurations of the production system. The overall approach is discussed with the help of a case study coming from the automotive industry. The case study introduces a production system integrating humans and autonomous mobile dual arm workers.

Index Of Agreement

Recently, a new estimation procedure has been developed to assess bias and precision of a new measurement method, relative to a reference standard. However, the author did not develop confidence bands around the bias and standard deviation curves. Therefore, the goal in this paper is to extend this methodology in several important directions. First, by developing simultaneous confidence bands for the various parameters estimated to allow formal comparisons between different measurement methods. Second, by proposing a new index of agreement. Third, by providing a series of new graphs to help the investigator to assess bias, precision, and agreement between the two measurement methods. The methodology requires repeated measurements on each individual for at least one of the two measurement methods. It works very well to estimate the differential and proportional biases, even with as few as two to three measurements by one of the two methods and only one by the other. The repeated measurements need not come from the reference standard but from either measurement methods. This is a great advantage as it may sometimes be more feasible to gather repeated measurements with the new measurement method.
