Performance Availability and Anticipatory Change Planning of Intralogistics Systems: A Simulation-Based Approach

In recent years, the ability to respond to real time changes in operations and reconfigurability in equipment are likely to become essential characteristics for next generation intralogistics systems as well as the level of automation, cost effectiveness and maximum throughput. In order to cope with turbulences and the increasing level of dynamic conditions, future intralogistics systems have to feature short reaction times, high flexibility in processes and the ability to adapt to frequent changes. The increasing autonomy and complexity in processes of today’s intralogistics systems requires new and innovative management approaches, which allow a fast response to (un)anticipated events and adaptation to changing environment in order to reduce the negative consequences of these events. The ability of a system to respond effectively a disruption depends more on the decisions taken before the event than those taken during or after. In this context, anticipatory change planning can be a usable approach for managers to make contingency plans for intralogistics systems to deal with the rapidly changing marketplace. This paper proposes a simulation-based decision making framework for the anticipatory change planning of intralogistics systems. This approach includes the quantitative assessments based on the simulation in defined scenarios as well as the analysis of performance availability that combines the flexibility corridors of different performance dimensions. The implementation of the approach is illustrated on a new intralogistics technology called the Cellular Transport System.

Storage as a way to grammaticalization

This paper explores the possible contribution of various types of storage to grammaticalization processes, and the description of such processes by means of Construction Grammar(s) (CxG). The grammaticalization processes of French pas and certain complex adpositions in German and Finnish serve to illustrate that storage can background the literal meaning of elements like pas, thus enabling the constructions containing them to grammaticalize. A further form of storage, the emergence of a productive template on the basis of high type frequency, may in turn stand behind their grammaticalization. Two further assumptions about language use are also exploited in the explanation of grammaticalization: the possibility of processing complex units holistically and a human urge to interpret recurring forms as signs.

Ansätze zur Ermittlung und Reduktion nichtproduktiver Zeiten an Tiefbohranlagen

Aufgrund der hohen Kosten für Tiefbohrungen ist eine wirtschaftliche Stromerzeugung aus der tiefen Geothermie derzeit nur bedingt möglich. Da die Herstellkosten einer Tiefbohrung direkt von der Herstellzeit abhängig sind, wird eine Optimierung der nichtproduktiven Prozesse angestrebt. Vorrangig sind die Prozesse zu betrachten und zu optimieren, durch die eine Unterbrechung des Bohrens auftritt. Dies ist hauptsächlich beim Transport der Rohre zwischen Lager und Arbeitsplattform sowie bei den Verschraubungsprozessen der Rohre der Fall. Im Rahmen dieses Beitrags werden Konzepte zur Umgestaltung dieser Prozesse und Bewegungsabläufe an Tiefbohranlagen entwickelt und auf ihr zeitliches Einsparpotential untersucht.
