* Die energieintensive Industrie kann zum Ausgleich volatiler Stromeinspeisungen und somit zum Gelingen der Energiewende beitragen. * Digitalisierungsprozesse ermoglichen die Flexibilisierung der Produktion, wodurch die Stromnachfrage steuerbarer wird. * Gegenwartig sind die Anreize zur...

Up to now, demand fulfillment in make-to-stock manufacturing is usually handled by advanced planning systems. Orders are fulfilled on the basis of simple rules or deterministic planning approaches not taking into account demand fluctuations. The consideration of different customer classes as it...

Integration of production planning and scheduling is a class of problems commonly found in manufacturing industry. This class of problems associated with precedence constraint has been previously modeled and optimized by the authors, in which, it requires a multidimensional optimization at the...

In every production plant, it is necessary to have an estimation of production level. Sometimes there are many parameters affective in this estimation. In this paper, it tried to find an appropriate estimation of production level for an industrial factory called Barez in an uncertain...

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...

This contribution summarizes recent work in the field of lot sizing and scheduling. The objective is not to give a comprehensive literature survey, but to explain differences of formal models and to provide some first readings recommendations. Our focus is on capacitated, dynamic, and...

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...

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...

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...

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...
