Lot-sizing problems of manufacturers and transportation planning problems of forwarders are presented and analyzed in this thesis. These problems represent crucial planning tasks in supply chain management. Due to high fluctuations and competitive markets, companies within supply chains use...

In this paper we consider the following problem: a Company wants to sell consecutive time slots on a single machine. It wants to maximize the revenues, whereby market prizes are not known. Additionally, consider a number of potential buyers of those time slots providing each at least one job....

Production planning and scheduling is one of the most important business processes that significantly influence the performance of manufacturing companies. There are many information systems supporting production planning and scheduling and some of them are based on very sophisticated planning...

Batch availability model, Batching and Scheduling, Completely-Knocked-Down. - This doctoral thesis introduces the problem of batching and scheduling non-permutation flow shops with m=2 batch processing machines in sequence and stage specific incompatible job families. Batches are builded at each...

This contribution presents an efficient solution method for solving the major short-term planning problems which occur, if lot production has to be managed. In our focus are the two most important aspects, i.e. lot sizing and scheduling. Since both problems heavily interact, we propose an...

Digitalisierung und Globalisierung führen für produzierende Unternehmen zu einer stetigen Verkürzung der Produktlebenszyklen und zunehmend intensiven Wettbewerb. Um diesen Herausforderungen gerecht werden zu können, müssen Produkt und zugehöriges Produktionssystem bereits in der...

In this paper, we develop a new mathematical model that integrates layout configuration and production planning in the design of dynamic distributed layouts. The model incorporates a number of important manufacturing attributes such as demand fluctuation, system reconfiguration, lot splitting,...

Production planning and control in remanufacturing are more complex than those in traditional manufacturing. Developing a reliable forecasting process is the first step for optimization of the overall planning process. In remanufacturing, forecasting the timing of demands is one of the critical...

The work is about fundamental parallel machine scheduling problems which occur in manufacturing systems where a set of jobs with individual processing times has to be assigned to a set of machines with respect to several workload objective functions like makespan minimization, machine covering...
