This paper investigates an initial model for Zero Defect Manufacturing (ZDM) using a cost function where the operation and condition of a production process are reflected, and the quality of the output/product and the production process (as well as safety aspects) can be considered. The outset of the study is based on empirical data collected from five manufacturing companies, and proposes an initial model for ZDM with an Industry 4.0 perspective. The initial ZDM model has a generic setup for a real-life system and its replication as a digital twin using system models based on a representation of a generic production process with its connected control system, and potential interconnections between unit processes. It is based on concepts from system theory of dynamic systems and principles from condition monitoring and fault detection. In that way the model is deemed as highly generalizable for manufacturing and process industry companies as well as for some critical infrastructures with production and distribution systems. The proposed model with its cost function setup is analyzed and discussed in the context of ZDM. It is concluded that production processes in the manufacturing and process industry can be made more intelligent and interoperable using this approach. Improved sustainability, competitiveness, efficiency and profitability of companies are foreseen welcomed secondary effects. Finally, the proposed ZDM model further develops the ZDM by adding to it a systematic approach based on a solid mathematical foundation.

The ancient tombs in Samga, Hapcheon, are proof of an ancient unglazed stoneware culture that follows the production and distribution systems of the inland Haman style. The stoneware excavated from Samga’s ancient tombs share similar compositions and change patterns with Haman-style stoneware. Tombs built after the early 4th century’s type I-1 separate-pit wooden chamber tombs were strikingly different from the previous tombs of Samhan Period in terms of size and the artifacts buried therein. The type I-1 wooden chamber tombs belonged to the local rulers of the Samga area in Hapcheon. This discovery suggests the emergence of a small state in the area, away from the center of Byeonhan and Jinhan, and a glimpse of the social and economic background of the builders of the Samga’s ancient tombs of that period. The early 5th century saw a temporary emergence of similar stoneware types across the Yeongnam region. The ancient tombs in Samga also held a type of stoneware culture centered on mounted cups that characterized the transitional period until the establishment of the post-Gaya stoneware style. Before the establishment of the post-Gaya stoneware style in the early 5th century, the ancient tombs in Samga already featured large wooden chamber tombs with crushed stones covering their entire lengths. The overwhelming size of the chamber and the quality of the funerary artifacts indicate that the tombs belonged to the highest rulers of western Gyeongsangnam-do as well as Samga area. The emergence of the builders of the ancient tombs in Samga in the late 5th century represents the establishment of the stratified central-tomb-peripheral-tomb system and the emergence of multi-chamber tombs in the Sogaya region. Specifically, the same assemblage and stylistic changes centered on stoneware styles appeared, with the establishment of a weaponry system focused on iron helmets and war swords. The artifacts from gigantic multichamber tombs built on hills in this period confirm the introduction and spread of foreign culture. These artifacts also show the pattern of exchange among Gaya factions in the area and their expansion. The cultures of Aragaya and, in particular, Daegaya began in the early 6th century, as can be seen from the tombs of local rulers. However, the style of the tombs implies that the multi-chamber tombs built with methods unique to the area continued until the first half of the 6th century. The funerary artifacts found in the M-2, 3, and 4 tombs in Zone I—which include iron-plate ritual utensils with bird decorations, round-pommel swords with three-leaf patterns, and horse harnesses—show that the ancient tombs in Samga are the central tombs of Sogaya, which is further supported by the internal and external capabilities of the area.

Coordination of the production and distribution activities represents a significant opportunity to cut costs and limit waste in the food supply chains. In this paper, we propose two mathematical models. The first one aims to integrate the harvesting, storage, and distribution activities of an agricultural company dealing with perishable products. The second one promotes horizontal collaboration between heterogeneous agri-companies for the distribution phase, in order to achieve cost savings. Computational experiments, conducted on a set of real-life instances, confirm the effectiveness and efficiency of the proposed models, which provide multi-level support. At the tactical level, managerial insights suggest the most profitable parameter setting, in terms of harvesting frequency and quality of service. At the operational level, the use of a heuristic framework can support the decision-making of the companies, suggesting when collaboration is profitable.

Raw materials is a major requirement in the production process for manufacturing companies. in fulfilling the needs of raw materials for the production process, most manufacturing firms depends on suppliers. Supplier selection is an important part of manufacturing companies. From several supplier selection criteria, quality is one of the important criteria and it used in supplier assessment. Selecting suppliers based on the quality of their products will have a positive impact on manufacturing companies, such as increased profits through reduced operational costs and increased market share. In this study will compare two suppliers at manufacturing companies and choose one that has a higher capability value. The selection of suppliers is made using the yield index of Spk with a single characteristic. Supplier will be selected by comparing the yield ratio of two suppliers. Numerical calculations are performed on suppliers based on pH levels on the leather. The pH level on the leather will affect the color. A low pH may result color degradation earlier, whereas a high pH may result poor color matching.

The problem of evaluation and selection of parking lots is a part of significant issues of public transport management in cities. As population expands as well as urban areas, solving the mentioned issues affects employees, security and safety of citizens, and quality of life in long-time period. The aim of this paper is to propose a multicriteria decision model which includes both quantitative and qualitative criteria, which may be of either benefit or cost type, to evaluate locations. The criteria values and the importance of criteria are either precise or linguistic expressions defined by trapezoidal fuzzy numbers. The human judgments of the relative importance of evaluation criteria and uncertain criteria values are often vague and cannot be expressed by exact precise values. The ranking of locations with respect to all criteria and their weights is performed for various degrees of pessimistic-optimistic index. The proposed model is tested through an illustrative example with real life data, where it shows the practical implications in public communal enterprises.

AbstractContemporary production companies operate in a dynamically changing environment and try to strengthen their competitive position. Therefore they take action acting at implementing new ones as well as improving and maintaining existing production processes, using for this purpose knowledge and available tools and methods. For dominant activities undertaken in the scope of improving and maintaining production the pro-quality activities can be included. Quality mainly depends on the efficiency of production processes, therefore manufacturing companies should focus their activities on maintaining and improving them. The methods of technical risk analysis and assessment are effective methods of maintaining production processes, whose application makes it possible to indicate any deviations from accepted standards. Analysis and assessment of the technical risk of the production process makes it possible not only to indicate non-conformities identified in the process, but mainly taking corrective actions. The aim of the article is to formulate of the method used to identify and assessment of the technical risk of the cutting process on the organizational side. The method has qualitative-quantitative type, and is the effective tools for technical risk assessment necessary to maintain the production process. It is assumed that the quality of the cutting process is ensured by the technical condition of the machine.

Raw materials are a significant requirement in the production process for manufacturing companies. In meeting the needs of raw materials for the production process, most manufacturing firms rely on suppliers. Supplier selection is an essential part of manufacturing companies. From several supplier selection criteria, quality is one of the fundamental standards and is used in supplier assessment. Selecting suppliers based on the quality of their products will have a positive impact on manufacturing companies, such as increased profits through reduced operational costs and increased market share. The problem faced is the lack of accuracy in choosing qualified suppliers. In this study will compare two suppliers at manufacturing companies and pick one that has a higher capability value. Supplier selection is made by using multiple characteristic capability indexes. The Supplier will be selected by comparing the ratio of two suppliers. Numerical calculations are performed on leather suppliers in shoe companies based on bursting quality, tear strength, tensile strength and elongation. The result of the calculation can be seen that supplier B is chosen as a better supplier. Characteristics of quality will affect the production process and application of shoes.

Political democracy should be equivalent to the economic development of the quality of democracy, economic democracy if not upright, even the owner of the ruling power and money, which is parallel to force global corporatocracy. Consequently, the economic oligarchy preservation reinforces control of production and distribution from upstream to downstream and power monopoly of the market. The implication, increasingly sharp economic disparities, exclusive owner of the money and power become fertile, and the end could jeopardize the harmony of the national economy. The loss of national economic identity that makes people feel lost the “pilot of the state”. What happens then is the autopilot state. Viewing unclear direction of the economy, the national economy should clarify the true figure.
