This note provides an alternative proof of a known result on the existenceof collections of orderings generating intersection quasi-orderings. Instead of proving theresult from rst principles, it is illustrated how it can be obtained by making use of ananalogous relationship between partial...

This paper presents a new algorithm for the dynamic Multi-Level Ca-pacitated Lot Sizing Problem with Setup Carry-Overs (MLCLSP-L). TheMLCLSP-L is a big-bucket model that allows the production of any num-ber of products within a period, but it incorporates partial sequencing of theproduction...

This paper presents an optimization-based solution approach for the dynamicmulti-level capacitated lot sizing problem (MLCLSP) with positive leadtimes. The key idea is to solve a series of mixed-integer programs in an iterativefix-and-optimize algorithm. Each of these programs is optimized over...

Die Leasingbranche zeichnete sich in den vergangenen Jahren durch die vermehrte Nutzung innovativer Refinanzierungsformen aus. Insbesondere die Technik der Verbriefung von Forderungen (Assetsecurization), die zur Behebung so genannter Leasebacked-Securities führt, hat sich für große...

Nowadays, managers are forced to excel competition on a global scale. Efficientbusiness processes have become a basic requirement to meet this goal. However,the design of efficient business processes and the improvement of existing ones is adifficult task that regularly overburdens human...

We consider the single item lot-sizing problem with capacities that are non-decreasing overtime. When the cost function is i) non-speculative or Wagner-Whitin (for instance, constantunit production costs and non-negative unit holding costs), and ii) the production set-upcosts are non-increasing...

Ein "Mehr" an Automatisierung bedeutet in der Regel ein "Weniger" an Flexibilität und umgekehrt. Standardisierte Prozesse wie sie bei der Massenproduktion vorkommen, lassen sich am einfachsten automatisieren und erfordern zudem eine geringe Flexibilität. Ganz im Gegensatz dazu steht die...
