The ANSI/ISA-95 (ISO 62264) standard is a key concept driving the implementation of Industry 4.0 in industry. It is a backbone of the Reference Architectural Model for Industry 4.0 (RAMI 4.0) and describes the objects, models and activities on operations management hierarchy level (Level 3). A major model described in the standard is the Planning model, in which is described that the planning activities rely on requirements of personnel, equipment and/or material. Also, a general concept in all models, described in the standard is the process segment that may refer as a combination of specific equipment/asset (with enough capability), a material (with specific quality) and/or a person (with proper qualification). In this article the Segment Dependencies impact on Capacity and Planning models is examined and some conclusions are made.
Industry 4.0 represents the newest generation of industry development. Every day the various demands in industry are getting more and more demanding. The demand for shorter production and delivery time, more efficient and automated processes has led us to the Industry 4.0. It is necessary to include and integrate the latest developments based on digital technologies as well as the interoperability process across them. The goals is to enable companies to transmit information in real time in terms of performance and behaviour. Industry 4.0 can be applied to any branch of industry. Agricultural industry is no exception. As far as agricultural machinery is concerned, it is a very important part of agricultural industry. Agricultural machinery incorporates electronic controls and it is a part of digital age, enhancing their current performance. In addition to the electronics, using sensors and drones, supports the data collection of several agriculture key aspects, such as weather, animals and crops behaviour, geographical spatialization, etc. The main tasks are how to apply the right methods and methodologies in order to support a better supply chain decision-making process, how to automate the process and how can Industry 4.0 help a person, who is in agricultural industry, in order to make effective decisions based on objective data.

Off-grid hybrid PV plants used to supply autonomuos internet base stations supporting the mitigation of GHG in Albania. Case study: Bulqiza district, Albaniapg(s) 174-178
This work is focused to an off-grid PV-Genset-battery application as one of the most feasible technology to power internet access points antennas enabling to reduce GHG-s. Solar energy is clean, infinite and environment friendly source of energy. Remote areas especially in northern part of Albania is facing difficulties to the connection to the national electricity grid. Primarily diesel generators (Genset) are used for electricity power supply leading to negative effects into the surrounding. However, hybrid energy systems, such as PVGenset-battery systems have a high potential to reduce CO2 emissions, fuel costs and total cost of the system compared to the other options applied historically in telecommunication sector in Albania. Such systems are foreseen to play a key role in a stable, costless and emissionless way especially in off-grid applications. The performance, availability, costs and carbon intensity of photovoltaic power all indicate that this technology can make a very substantial contribution to reduce carbon emissions and gain carbon credits.

The paper describes the problems faced by the company in production monitoring and gives a proposal for the application of RFID technology to monitor the production and to facilitate production management using an ERP system.
SOCIETY & ”INDUSTRY 4.0”
The bioeconomy, as a complementary segment of the circular economy, encompasses all sectors and systems that rely on biological and environmental resources, their functions and principles. It can lead to the discovery of new opportunities to provide food, goods and energy without depleting the planet’s limited biological resources. It can turn algae into fuel, recycle plastics, produce furniture or clothing from waste, and create organic fertilizers from industrial waste products. It has the potential to create over a million new “green jobs” by 2030. Bio-sector enterprises play a key role in accelerating the achievement of the UN’s global goals. They contribute to reducing climate change and waste, creating new jobs and building sustainable development in a modern society. Corporate social responsibility is a concept that reflects the quality of the relationship between an organization and society. According to the European Commission’s Green Paper, Corporate Social Responsibility (CSR) is “a concept that serves companies as a basis for voluntarily integrating social and environmental aspects into their business strategies and relationships with all stakeholders.”
The purpose of this report is to examine how the principles of corporate social responsibility affect biosector enterprises in Bulgaria and the adequacy of the country’s policy to engage them to adopt global goals for sustainable development. The results of the study show that CSR is not seen as a one-time act, but as a sustainable process, helping to balance the three pillars of sustainable development – economic growth, social development and environmental protection.
