In this paper we report on the results of an interview research about new product development (NPD) processes and planning in 15 Japanese mechanical and electrical engineering companies. We asked the companies to describe one successful and one less successful project. All in all, we collected...

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...

Heuristische Optimierungsverfahren sind universell einsetzbare Verfahren, welche mit realitätsverträglichem Rechenaufwand hochwertige Lösungen ermit-teln und damit zur effektiven Bewältigung realer Entscheidungsprobleme beitragen können. In dem Beitrag werden Herausforderungen für die...

In our competitive world, companies need to adapt their processesquickly in order to react, for instance, to changing customerdemands. Process models, as means to support processmanagement, are nowadays often created and adapted in a timeconsuming,widely used manual manner. Semantic...

Die Beteiligung einer breiten Masse von Personen an einem kommunikativen Planungsverfahren benötigt ein Medium, in welchem Meinungen geäußert wie gehört werden können, welches Zugang zu Informationen gibt und für jedermann erreichbar ist. Moderne Informations- und Kommunikationstechnik...

In diesem Beitrag wird zunächst eine ausführliche Definition des Begriffes "Unternehmenskultur" geliefert und anhand von Beipielen erläutert.

A general model for job shop scheduling is described which applies to static, dynamic and non-deterministic production environments. Next, a Genetic Algorithm is presented which solves the job shop scheduling problem ...
