Case Study on Numerical Calculation of a Disc Bush in the Disc Harrow in the Welding Version

The optimization of production processes in companies comes down to two main measures influencing the economic factor. The first one is the reduction of interval micro-periods between operations, and the second is to use post-production waste as much as possible. These treatments apply to virtually all industries regardless of the final product effect. This article describes the application of a special welding device for welding the workpiece with a bush type, designed for fixing the plate in the plate gun. As a result of its application, a significant reduction of time needed to produce one bush has been achieved, and thus the amount of time in a unit of time has been increased. As part of the implementation work, the bush design changes were also made, which made it possible to reduce post-production waste not suitable for current production, but allowing its use for other purposes. The results of the work were implemented in the company producing agricultural machinery in Lublin.

This article is intended to introduce the reader to the basic ways of increasing the efficiency of current production when problems arise from inaccurate planning of production. The article is based on a study that is gradually implemented as system measures in actual production. Simple and logical improvements bring efficiency improvements and production deadlines. The methods used are suitable for both production and logistics. The study is for a medium-sized company. But the authors want to extend it to small businesses. Small businesses do not fully perceive this area, nor do they accept problems in this area. As part of consultations and inspections, we find that small businesses have significant systemic shortcomings, but owners do not admit this.

Current supply chain methods are having difficulties in resolving problems arising from the lack of trust in supply chains. The root reason lies in two challenges brought to the traditional mechanism: self-interests of supply chain members and information asymmetry in production processes. Blockchain is a promising technology to address these problems. The key objective of this paper is to present qualitative analysis for blockchain in supply chain as the decision-making framework to implement this new technology. The analysis method used Val IT business case framework, validated by the expert judgements. The further study needs to be elaborated by either the existing organization that use blockchain or assessment by the organization that will use blockchain to improve their supply chain management.

AbstractFood products suitable for Muslim consumers should be halal certified, particularly when their origins or production processes are doubtful. However, there is a multiplicity of halal standards. This situation may generate confusion, particularly for producers in Western countries who would like to certify their products in order to export them to Islamic countries. This study analyzed the reasons underlying the multiplicity of standards and reviewed the attempts of harmonization over time. Then, the case study of application to slaughterhouses was considered, by comparing four different halal standards (namely GSO 993:2015, OIC/SMIIC 1:2019, HAS 23103:2012, and MS 1500:2019) representative of different geographic areas. Animal stunning was critically examined, comparing tradition with modernity. The study evidenced that the basic requirements related to slaughtering are common to all the halal standards considered, but several differences occur in more specific details. Only a close collaboration between the authorities of all the countries involved in issuing halal certifications will lead to a homogeneous regulatory framework with unified certification and accreditation procedures, increasingly required in a globalized market.

Product family (PF) design is a widely used strategy in the industry, as it allows meeting diverse design requirements. Change propagation in any PF is difficult to predict. Consequently, while numerous design change management methodologies presently exist, their application is restricted to a single artifact. This issue is overcome in the present study. The proposed framework explores effective change propagation paths (CPPs) by considering the risks associated with design changes in the PF with the aim of minimizing the overall redesign cost. The propagated risk, which would result in rework, is quantified in terms of change impact and propagation likelihood. Moreover, a design structure matrix (DSM) based mathematical model and an algorithm for its implementation are proposed to investigate the change propagation across the PF. Finally, to demonstrate their effectiveness, a PF of electric kettles is examined in a case study. The study findings confirm that the proposed technique is appropriate for evaluating different CPPs in PF.

Cheese Production

Individual entrepreneurship and social entrepreneurship may be more common both in daily life and in the research literature, but community- based entrepreneurship also plays an important role in economic development. We present a case study of community entrepreneurship in a rural area of the Andes, where the community of Chijnaya operates a successful cheese production business. Buying milk from its farmer members in the community, the business produces cheeses that are sold in regional urban markets and beyond. This account draws on decades of ethnographic research and collaboration with the community. Here, we discuss the history of the community in general and of the cheese enterprise in particular. The organizational structure of the business is outlined along with a description of the production processes. We end with an analysis of problems faced by the community in moving the enterprise forward toward a more profitable future and a discussion of the relevance of this case to entrepreneurship studies.
