The repair and maintenance operations carried out within a shipyard are correlated with the process of ensuring and managing the resources necessary to carry out the works included in the technical specification. Resource planning is a complex issue that can be addressed from several points of view. Initially, the planning of activities is done taking into account only the analysis of the time parameter and the dependencies between activities imposed by the technological process. The practice of the activities carried out in a shipyard has demonstrated that an analysis of the necessary resources according to the existing availability is also necessary. There are many unforeseen situations that can affect both the time of work and resources (material, financial, human) thus complicating the process of planning activities. This paper proposes a way to analyze the resource requirements of a repair project based on available resources, through Critical Path Method diagrams. This provides a comparative view of the daily required profile for a particular resource associated with the project in respect to the daily available profile of the shipyard.

Production planning and control (PPC) is the heart of any manufacturing company and entails tasks such as resource planning, sequencing, or capacity control. While an increasing complexity within production makes it difficult to determine the best production plan, the advances in PHM and the emergence of predictive maintenance also offer new opportunities to optimize PPC. While there is much research on PHM and PPC, little has been done to align both disciplines. Through post-prognostics decision-making, different PPC decisions, such as continuing the production, shutting down a machine, or reducing its workload, can be elevated by a remaining useful life (RUL) estimation. However, it is unclear how exactly this prognostics information can be exploited and how processes, organization, and technology must be aligned to attain a more efficient and flexible production. Further, PHM has long been implemented beyond research, but it is unknown whether and how practitioners intertwine it with their PPC. This work aims to analyze how processual, organizational, and technological changes through PHM can lead to advanced PPC. This goal is attained by means of a multivocal literature review (MLR) in which scientific PPC and PHM literature and standards are analyzed, and an aligned PPC process proposed. The findings are juxtaposed with grey literature, revealing fits and gaps between research and practice, and a research agenda is presented.

This article focuses on various features of product data management system (PDM). A PDM system manages all forms of product data; that is, computer-aided design or text files, or anything else concerning product development. PDM systems also ensure that bills of material are generated on the design side. The bill of material describes exactly what parts will be used in each manufactured product. Using the bill of material (BOM), a manufacturing engineer determines the most efficient set of operations to manufacture a product and may request a design modification to streamline production. BOM development should logically take place in the PDM system at the same time the product is being developed and then should be released to the enterprise resource planning system—and thus to the manufacturing side—when the product design is complete. An enterprise-resource planning system is a company’s operational, planning, and control system used to manage the resources of the manufacturing part of the operation.

Automatisierung, intelligente Produktionsplanung und Monitoring sind gängige Anwendungen – daher sind Informationstechnologie (IT)-Systeme aus der Produktion nicht mehr wegzudenken. Dieser Beitrag gibt einen Überblick über die aktuellen Entwicklungen und Innovationen im Bereich der Produktions-IT (zum Beispiel Enterprise Resource Planning ERP, Manufacturing Excecution Systems MES und Computer Aided Quality Assurance CAQ), nennt Anwendungsgebiete und beleuchtet deren Potenziale anhand konkreter Fallbeispiele. Es werden darüber hinaus die Herausforderungen diskutiert, welche es im Rahmen von Industrie 4.0 zu meistern gilt.   IT systems nowadays are common in manufacturing environments for applications such as automation, intelligent production planning or monitoring. This article provides an overview about current developments and innovations in production planning and control (e.g. ERP, MES; CAQ), mentions promising areas for application and evaluates their potential referring to case studies. Based on this, challenges coming along with changes within the broad field of Industry 4.0 are discussed.

The growth in horticultural and some industrial development in selected areas of Northland has led to a need for more specific and careful planning and control of limited resources in a number of major catchments. The potential irrigation demands for horhculture comprise over 60% of Northland's potential water requirements. By contrast, farm water supply needs are only 11% of these needs. Because of their importance to the Northland economy, and in the legislation these needs are given a high priority in water resource management planning. Land uses, including pastoral farming, require careful operation to reduce diffuse sources of pollution.
