This paper presents a profit-oriented shift scheduling approach for inbound contact centers. The focus is on systems in which multiple agent classes with different qualifications serve multiple customer classes with different needs. We assume that customers are impatient, abandon if they have to...

This paper explores a single-item capacitated lot sizing problem with minimum order quantity, which plays the role of minor set-up cost. We work out the necessary and suffcient solvability conditions and apply the general dynamic programming technique to develop an O(T³) exact algorithm that is...

The paper deals with the analysis of a special dynamic production and inventory model. In this model logical restrictions to fulfill an accepted constant minimal level of the production lot size are incorporated, instead of keeping setup cost in the objective function, as it is common in many...

The most recent optimization algorithm for (s, S) order policies with continuous demand was developed byFedergruen and Zipkin (1985). This was also the first efficient algorithm, which uses policy iteration instead ofdiscretization. Zheng and Federgruen (1991) developed an even more efficient...

This paper extends a fundamental result about single-item inventory systems. This approachallows more general performance measures, demand processes and order policies, and leads toeasier analysis and implementation, than prior research. We obtain closed form expressions forthe Laplace...

This article studies specific aspects of the joint replenishment problem in a realsupply chain setting. Particularly we analyze the effect on inventory performance of havingminimum order quantities for the different products in the joint order, given a complextransportation cost structure. The...

The production planning problem of flexible manufacturing system (FMS) concerns with decisions that have to be made before an FMS begins to produce parts according to a given production plan during an upcoming planning horizon. The main aspect of production planning deals with machine loading...

Flexibilität wird im globalen Wettbewerb immer wichtiger. Viele Kunden erwarten kurze Lieferzeiten bei hoher Termintreue und die Fähigkeit, Produkte kurzfristig an ihre individuellen Wünsche anpassen zu können. In Industrieunternehmen wird daher neben entsprechenden organisatorischen...

* 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...
