The purpose of this paper is to present a maintenance study focused on total productive maintenance (TPM) and reliability-centered maintenance (RCM). Its approach is based on the first pillars of TPM, preventive and autonomous maintenance, as well as the FMEA analysis of RCM for maintenance analysis, which was conducted in this study. The implementation of TPM was successful in that various preventive maintenance (PM) policies assigned to the assets were implemented and it was demonstrated that TPM application in the construction industry could reduce the excessive accumulation of maintenance with the same effective optimization, and with support from RCM analysis and its heavy equipment systems analysis. Excessive corrective maintenance accounts for high investment and delay rates in work times of the assigned project. Traditional methods of availability guarantee, such as reactive or routine maintenance, are insufficient to satisfy a heavy equipment maintenance plan; therefore, what is called for is the systematic application of RCM and TMP because they allow the selection and application of effective PM tasks. An approach that develops and thoroughly analyzes the strategies of continuous corrective and PM is used with an atmosphere of uncertainty and with operational data limited by criticism. Results show a 90% improvement in availability. / Revisión por pares

In recent years, the giant squid processing industry in Peru exhibited a 59% increase in exports with respect to 2018. According to estimates, this industry generates approximately 30,900 jobs per year. However, some SMEs experience low productivity, such as the PECEPE company, due to plant downtime. This represents 26% of the available time, which translates into the loss of 1760 tons every year. The most constraining external factor the sector faces is uncertainty in resource availability caused by changing weather conditions and informal fishing activities. Although there is a large number of research studies on the fishing industry and resource extraction, literature on processing plant operations is scarce. Within this context, this study seeks to promote a high impact sector in Peru, as well as fostering processing plant competitiveness and productivity. Hence, to address these issues, the authors propose a maintenance management model under the TPM approach. As part of the results from model implementation, a 39% decrease was reported in plant downtime, while maintenance costs also decreased by 16%, which, in turn, increased machine availability and production by 784 tons per year.

Syftet med denna uppsats är att undersöka vad den horisontella kommunikationen har för roll inom systemförvaltning, och att undersöka vad en effektiv sådan har för påverkan på förvaltningsarbete. Då systemförvaltning är kostsamt är det viktigt för organisationer att det sker effektivt. Effektiviteten i organisationers arbete påverkas av kommunikationen och för att uppnå en effektiv kommunikation krävs en förståelse för horisontell kommunikation. Men inom styrning av systemförvaltning ligger inte fokus på kommunikation. Undersökningen genomfördes med hjälp av kvalitativa semistrukturerade intervjuer. Förvaltningsledningar på en organisation vars förvaltningsarbete styrs av förvaltningsmodellen pm3 studerades. Uppsatsens resultat visar på att en horisontell kommunikation utspelar sig inom förvaltningsarbete, det krävs en kommunikation mellan vissa arbetsroller. Den horisontella kommunikationen har också en betydande roll, då den kan hjälpa till att upprätta enhetliga arbetssätt. Resultatet visar dock att den horisontella kommunikationens funktion inte alltid utnyttjas till fullo. När den inte är effektiv kan det bidra till duplicerat arbete, förlorad och utelämnad information, samt att medarbetares kunskap förbises. Allt detta påverkar i slutändan arbetets produktivitet. Uppsatsens resultat visar att desto effektivare den horisontella kommunikationen är inom förvaltningsarbete, desto effektivare blir arbetet. / The purpose of this thesis is to examine what role lateral communication within the work in software maintenance has, and to examine how an effective lateral communication influences the maintenance work. Software maintenance is costly, therefore it is important for organizations that it is efficient. Organization’s efficiency is influenced by their communication. To attain an effective communication there needs to exist an understanding for lateral communication. Within the guiding of software maintenance there is a lack of regard to the importance of communication. The thesis was conducted using qualitative research. The research is based on semi-structured interviews with solution managers at an organization that has their software maintenance guided by the swedish maintenance management model pm3. The result of this study shows that a lateral communication occurs within the work with software maintenance, communication is required between certain roles. Lateral communication also has a significant role since it can help to uniform the work. However, the results show that the potential of lateral communication is not always used to its full extent. When it is not effective it can result in duplicated work, lost and excluded information, and coworkers’ knowledge can be overlooked. In the end the productivity of the work is affected. The study shows that the more effective the lateral communication is within the work in software maintenance, the more effective the work will become.

The maintenance management model (Pm3) is a management model whose goal is to contribute to the collaboration between the business and IT. An implementation of pm3 involves applying the model, it must be implemented with the business existing governance and work methods. The purpose of the study is to investigate to be able to describe and evaluate the use of pm3 as a management model in a state agency. The study is carried out at the Swedish Transport Administration and their implementation of pm3. The aim of the study is to answer the research question which is “how pm3 can be implemented and applied to be more effective?”. The strategy that has been applied is a case study. The data collection methods are interviews and document studies where qualitative data has been generated. The results of the study show a number of different positive effects that implementation of pm3 can have on a business such as better collaboration, cost effectiveness and clearer overall picture. Some challenges and problems are also identified and a lot of them can be linked to the lack of implementation of the model at the Swedish Transport Administration. To maximize the implementation of pm3, this study has come to the conclusion that it is important with internal education in the management model. This to increase the chance of a successful implementation. Taking external help from the pm3 license is also a way to improve the implementation, as it offers external help and support from external experts. After implementation, it is also important to have an active management of the model, so that the business receives support to work properly over time. Recommendations for future studies is how to follow up on your implementation and establish your governance with pm3 over time.
