The issue of adapting enterprises to operate in accordance with the assumptions of the Industry 4.0 concept now requires performing highly complex and responsible analyses in manu-facturing enterprises. Based on the Industry 4.0 concept, maintenance services and also the imple-mented IT solutions in a production enterprises are now a significant factor in their development process. The article presents an analysis of the degree of use of the Manufacturing Execution Sys-tem (MES) in the maintenance department based on an example of a manufacturing company in the automotive sector of this industry. The analysis was performed in terms of the degree of ex-ecution of specific business processes in the maintenance department with the help of MES. The results of the analysis allow to confirm the possibility of adapting the enterprise to the Indus-try 4.0 concept.
Modern technical environments require a high degree of reliability both in machinery and in equipment. Technological progress has, on the one hand, increased this efficiency but on the other hand, it has changed the way in which this equipment and these machines have traditionally been maintained. The authors have set the following assumptions. In order to survive in the market and develop, modern production enterprises realize the assumptions of Industry 4.0, wherein the optimization of maintenance processes is important because of the financial situation. This includes the profits made by the production company and differs from traditional maintenance, by shifting towards new trends such as predictive maintenance; as such, it is crucial for the development of the company. The article is devoted to the most modern predictive maintenance strategy, in the maintenance department of a manufacturing company. The publication describes the meaning of the method, its potential and the theory of action.
Railway maintenance especially on infrastructure produces a vast amount of data. However, having data is not synonymous with having information; rather, data must be processed to extract information. In railway maintenance, the development of key performance indicators (KPIs) linked to punctuality or capacity can help planned and scheduled maintenance, thus aligning the maintenance department with corporate objectives. There is a need for an improved method to analyse railway data to find the relevant KPIs. The system should support maintainers, answering such questions as what maintenance should be done, where and when. The system should equip the user with the knowledge of the infrastructure’s condition and configuration, and the traffic situation so maintenance resources can be targeted to only those areas needing work. The amount of information is vast, so it must be hierarchized and aggregated; users must filter out the useless indicators. Data are fused by compiling several individual indicators into a single index; the resulting composite indicators measure multidimensional concepts which cannot be captured by a single index. The paper describes a method of monitoring a complex entity. In this scenario, a plurality of use indices and weighting values are used to create a composite and aggregated use index from a combination of lower level use indices and weighting values. The resulting composite and aggregated indicators can be a decision-making tool for asset managers at different hierarchical levels.
Buildings are designed with the intent of lasting for a certain period of time. Building maintenance in different building typology is described as multi-faceted activities which involve planning, directing, controlling and organizing resources for the sustenance of the building’s physical, functional and operational performance. The research focused on ways cost of maintaining a building was done, effectively or efficiently with the influence of the design approach used. Literatures of works pertaining to building maintenance were reviewed to identify the various impacts, influences that a building design would have on the cost of maintaining any building type. Maintenance departments of educational institutions were surveyed and data analyzed. The study revealed that maintenance culture of buildings could either be positive or negative, based on the quality of design approach used. The study recommends a proper review of building codes and regulations by organizations intending to erect building structures with a view of designers to specified standards and prevent excess maintenance cost in the future.
try to cut the nail at the fracture site, and extract the 2 segments separately. No specialized instruments were available, so we decided to use tools from our maintenancedepartment. A 30 mm diameter, diamond tipped cutting disk ( Figure 2 ), made in China and unbranded, was purchased at a local market for USD 1.50. This disk could be mounted on a regular orthopedic Stryker 2102 drill. A 100 mm diameter diamond-tipped cutting disk ( Figure 3 ), also made in China and unbranded, was purchased at the market for USD2.50. This disk could not be mounted on any of our
