Maintenance

In view of global competition, companies need to respond flexibly to market requirement and customer demand. Key factors in this challenge are the efficient operation of production facilities and the ability to manufacture in small batches. In particular, small and medium-sized enterprises (SME) often do not have sufficient personnel and methodical resources for a systematic and sustainable improvement of manufacturing processes. The standard program “management of manufacturing resources” provides structural and methodical support in order to be able to meet these challenges.

The efficient performance of service tasks on high-value capital goods like maintenance, repair and overhaul of aircrafts and railway vehicles is influenced by a turbulent environment. In this context, excellent production logistics in maintenance shops can be a way out to cope with this turbulence. This contribution describes a bottom-up approach which is the basis for improving the logistical processes by dimensioning material flow-oriented buffer stocks.

In recent decades the maintenance has experienced a continuous change in the industry by the requirements and thus their influence has risen to the production system. But every industry and every production process is affected differently from it. In this paper, therefore, the most recent developments in the maintenance be excerpted from current studies and transferred into the automotive industry, specific into the supplier industry with screen printing products. Previously we created from current studies for the changing meaning of maintenance a cause-effect diagram. In order to raise the perception of the maintenance change in the industry, we conducted subsequently by an expert survey. From this we were able to describe deriving effects on the production system and the formulation of future research needs.

Maintenance is an important factor for the effectiveness of production processes. As the degree of automation and interoperation of production equipment is increasing, the significance of equipment availability and thus of maintenance is increasing. At the moment, maintenance and service engineers spend a lot of time in retrieving and preparing information. In many cases the data of business information systems is not or only partly available to maintenance engineers. In the future, resource-cockpits on mobile devices will provide maintenance and service engineers with all necessary information in situ. This will be realised interactively, with little effort and in the right context.

Multivendor capable service companies are facing growing challenges concerning the alignment of their technological capability portfolio to dynamic market requirements. This paper presents a method that enables practitioners from technical service companies to systematically manage their capability portfolio using both qualitative and quantitative data. Thereby decision makers are provided with a tool to help them shaping the company’s service portfolio.

Atlas Elektronik is a leading systems house for maritime electronics and stands for maritime security world-wide. Our combat and sonar systems are integrated on various naval platforms, like frigates, corvettes or conventional submarines. Besides building and integration phases for such systems, especially the operational phase of 25 or more years is a big challenge regarding reliability, maintainability and supportability. Special demands have to be fulfilled. To cope with these challenges in an early stage, the methods of Integrated Logistics Support (ILS) are implemented already in the design phase. Thus, it is possible to increase the operational availability while simultaneously reducing the life-cycle costs.

The planning and control of regeneration processes, especially those with complex investment goods, comprises a high level of requirements. In order to efficiently design capacity planning and tuning despite fuzzy load information, this paper presents a database model that serves as ascertainment of this information.

Throughout the whole lifecycle, maintenance activities generally have to be fulfilled regarding technical systems. In logistics networks the creation of value at the nodes by means of rapid turnover is important, so that the availability of the production factor “machine” is essential. The increase in efficiency of support processes encompasses among others the maintenance of machines and installations. Within the paper, a procedure model with case study is presented, which illustrates the change-over to a condition-based maintenance strategy in the seaport surrounding.

Today, the maintenance of pump systems is based mainly on either a breakdown strategy or a time-based maintenance strategy. There are several disadvantages of these strategies: the required availability often is not reached, unscheduled downtimes occur and costs increase because of necessary redundant resources. In future, the requirements of a plant for efficient and cost-effective operation can only be reached through predictive maintenance. In this context, the combined use of technologies like RFID (Radio Frequency Identification) and condition monitoring techniques is a possible solution to increase the efficiency of operation and maintenance. This is accompanied by significant technology-driven organizational changes in maintenance as simplification of work procedures, additional personnel qualification requirements and decentralization of maintenance activities, i.e. on-site maintenance of pumps. Thus, the efficiency and effectiveness potentials of maintenance will be realized ...

Enterprises increasingly seek to differentiate from competitors by offering complete solutions in form of aligned goods and services. Effectively and efficiently offering such integrated solutions (also referred to as hybrid value bundles) requires an integration of production’s and service unit’s data and processes. Supporting the required data exchanges and providing novel functionality opens up new vistas for vendors of ERP systems.
