The article discusses the methodology for assessing the degree of cyclical use of resources, during the determination of the residual resource of engineering systems during the operation of buildings. The proposed key performance indicators measure various parameters that are not directly related: energy, materials, social impact, and are both quantitative and qualitative indicators. Consequently, the proposed methodology performs the procedure for calculating indicators independently, which in turn allows the effective use of materials at the design stage of buildings, as well as during their operation. In this article, a methodology for calculating the recycling index of materials is obtained.

Performance measurement is crucial for achieving business success. Moreover, such success is also related to the fulfillment of the organizational strategic objectives. Hence, an adequate determination of relevant performance indicators—or key performance indicators (KPIs)—and their relationships to organizational objectives is needed. Even though several approaches for treating KPIs and objective-KPI relationships have been proposed, they exhibit some drawbacks associated with the lack of reusability and traceability. We attempt to fill this gap by proposing a set of patterns based on pre-conceptual schemas for supporting the systematic derivation of KPIs and their relationships to organizational objectives. In this way, the proposed patterns guarantee a reusable and traceable derivation process of a set of candidate KPIs from organizational strategic objectives. Lastly, we provide a lab study in order to illustrate the usefulness of this proposal.

The efficient use of water resources is one of the main challenges of the steel sector, according to the European Union water policy. On this subject, monitoring and optimization systems, linked to the innovative water treatments, represent important tools to improve water management and the related energy use. The present paper describes a part of the work developed in the early stage of the project entitled “Water and related energy Hub Advanced Management system in steelworks – WHAM”, which is co-funded by the Research Fund for Coal and Steel. The project aims at optimizing water consumption in the steelworks through a holistic combination of on-line monitoring and optimisation and innovative water treatment technologies. As different aspects affect water use in the steelmaking processes, in the first part of the paper, the main technical barriers and factors, that can impact on reuse and recirculation of wastewater and energy efficiency, are analysed. The main constraints on water management in the steel sector, such as fresh water availability, its quality and local legal requirements, were considered in order to maximise the water reuse and recycling. Furthermore, the main barriers, such as environmental issues and several costs, were investigated. In the second part of the paper, a set of Key Performance Indicators are listed. They aim at assessing and monitoring the water management sustainability in a holistic way, both in terms of environmental and economic performances, as well as of new water treatments efficiency and their economic viability. Key Performance Indicators will be used to monitor the efficiency of water management, aiming at achieving significant increase of performances. On the other hand, some of these indicators will be used as objective functions for problems optimization. The computation of the selected Key Performance Indicators will take into account both industrial data and results from simulations that will be carried out after the development of suitable tools in order to assess the feasibility of some relevant process modifications or the applications of new technologies.

The article highlights the theoretical approaches for determination of a performance indicator as a tool for management accounting and internal control of a business, on the basis of which various decisions regarding business strategy and personnel motivation may be made. The analysis showed that it is important not only the approach of their definition, but also the data for determination of these indicators. The article provides recommendations for the preparation of accounting policies for revenue accounting in accordance with IFRS 15, which may significantly affect the performance indicators of the company.

Each sugar factory needs appropriate guidance to produce the desired white sugar product and co-products in their installed process equipment from the received sugar beet in a cost-effective way. Based on the generally known principles of sugar technology and supported by the extensive experience in beet sugar processing, this paper provides an overview of important key performance indicators (KPIs) which a factory could use as targets to optimize their beet processing. The recommended technological process set-points, which are required to fulfil the defined KPI targets, will be covered too. The theoretical background of sugar process technology is at the basis for the determination of the recommended process control parameters and will be used to explain the preferred choices of KPIs and process set-points.

Buildability seeks to improve efficiency of the overall building process by developing construction sensitive designs. The objective of this study is to investigate the relative importance of the key performance indicators of construction projects with respect to buildability at the design stage in the Malaysian construction industry. To achieve this objective, a questionnaire survey was distributed among key construction personnel to identify the most common buildability attributes in Malaysia. Then, an interview with eight construction professionals was conducted to compare the common buildability attributes with project performance criteria such as time, cost, quality, safety, and environment. The results reveal the equal importance of time and cost for buildability of the building, followed by quality, safety, and the environment.
