In recent years, the technique of centralized control of complex production processes has moved from the stage of development and experimentation to widespread industrial implementation. Centralized control equipment is used in large, complex objects, and the control systems themselves are so complex that they cannot be calculated or reasonably selected using the methods used for conventional control and measuring equipment. The work undertaken recently in order to create various calculation methods for centralized control systems, at best, solved individual particular problems, often from different initial positions, and, apparently, there was a need for generalizing work that would give the system designers centralized control is an efficient settlement tool. Of the technical characteristics of centralized control systems, the most essential and most fully reflecting the effectiveness of their operation is accuracy, especially if this concept is broadly approached, including any deviation from the required system behavior in the error. Centralized control systems are used in various fields: to control production processes, for scientific research, including space objects, for testing and researching technical structures, for monitoring the health of complex equipment. These applications have a number of similarities and, however, differ in the number of requirements put forward by individual applications. When writing the article, the main attention was paid to centralized control systems for continuous production processes, which, in contrast to a number of testing and research systems, are characterized by the duration of action, since the production processes themselves in most cases run continuously for many hours, days or even months.

AbstractIndustry 4.0 (I4.0) brings together new disruptive technologies, increasing future factories’ productivity. Indeed, the control of production processes is fast becoming a key driver for manufacturing operations. Manufacturing control systems have recently been developed for distributed or semi-heterarchical architectures, e.g., holonic systems improving global efficiency and manufacturing operations’ reactiveness. So far, previous studies and applications have not dealt with continuous production processes, such as applications for Water Supply System (WSS), oil refining, or electric power plants. The complexity of continuous production is that a single fault can degrade extensively and even cause service disruption. Therefore, this paper proposes the Holonic Production Unit (HPU) architecture as a solution to control continuous production processes. An HPU is created as a holon unit depicting resources in a continuous process. This unit can detect events within the environment, evaluate several courses of action, and change the parameters aligned to a mission. The proposed approach was tested using a simulated model of WSS. The experiments described in this paper were conducted using a traditional WSS, where the communication and decision-making features allow the application of HPU. The results suggest that constructing a holarchy with different holons can fulfill I4.0 requirements for continuous production processes.

This article discusses the use of Internet architecture in centralized automated process control systems for the purpose of monitoring and managing geographically distributed objects. The hardware components of the proposed architecture are described and the required functions are formulated. The methods of implementing these functions of centralized control systems based on this architecture are proposed: using internal algorithms of SCADA systems, or using microprocessor subsystems. The difficulties that are likely to be encountered when implementing all the required functions in the system being developed are described.

The purpose of this study is to analyze the internal and external factors that influence development and provide proposals for competitive strategies which are the priority of developing CV Angkasa Jaya. This study uses Strength, Waekness, Opportunity and Threat (SWOT) methods to identify internal and external factors of the company as well as alternative strategic planning and Fuzzy Analytical Hierarchy Process (FAHP) for determining strategic priorities. The results showed that internal and external factors that affected were products, marketing, production processes, the existence of government support, fruit beverage trends, market potential, technology, competition, shifting market tastes, economy and substitute products. Alternative strategies that become priority development strategies that can be applied by CV Angkasa Jaya are to increase the use of production technology and the internet, improve and maintain product quality in order to be able to compete with other products, develop business potential by making product innovations, carry out continuous production processes, improve and maintain market share, increase production capacity and the last priority is to increase promotion.

Information communications networks, and especially their industrial versions (field networks), are an inseparable element of contemporary control systems. They enable pieces of modern industrial equipment to be coupled into a common system. In the case of older-generation equipment (universal one-stand CNC machine tools, manipulators, robots), their extension and integration in either dispersed or centralized control system is possible. As a result of modernization, it is possible to create a production line that will be built based on classic CNC machine tools and operated by manipulators or robots using network solutions and PC computers.
