How to be successful in imitation management?

Schewe, Gerhard - 1993

There is often a clash between the necessity to innovate and the high economic risks involved in the introduction of novelties. The technology-strategies developed in reaction to this situation aim at profiting from the technological leader's or the innovator's experience: the technological...

Multi-level, single-machine lot sizing and scheduling: With initial inventory

Kimms, Alf - 1993

This paper presents a mixed-integer program for the dynamic lot sizing and scheduling problem in a multi-level, single-machine environment. It turns out that in contrast to single-level problems the integration of initial inventory is a crucial aspect if generality should not be lost. It is...

Analysis of profit contribution variance between actual and plan

Albers, Sönke - 1993

The traditional techniques of calculating quantity and price variances for analyzing deviations of realized profit contribution (actual) from the planned profit contribution only offer the benefit of identifying areas where problems may exist, rather than diagnosing the causes of these problems....

Experiments in competitive product positioning: An equilibrium analysis

Marks, Ulf G.; Albers, Sönke - 1995

Almost all of the results on competitive product positioning derived in respective literature so far are based fimdamentally on the hypothesis that Nash-equilibria are "accurate predictions" of final market configurations. If the positioning behavior of firms differs from this assumed...

Handelsvertreter oder Reisende? Eine Überprüfung von Hypothesen der neuen Institutionenlehre zur Absatzformwahl

Krafft, Manfred - 1995

In der jüngsten Vergangenheit wird der Effizienz und Effektivität von Funktionen, die von Unternehmen selbst wahrgenommen werden, erhöhte Aufmerksamkeit geschenkt. Während diese Diskussion bisher auf den Bereich der Beschaffung und Produktion beschränkt war, wird neuerdings im Rahmen von...

A guide to complexity theory in operations research

Schirmer, Andreas - 1995

inventive and persistent researchers, it seems virtually impossible to find efficient algorithms. In this Situation, the theory … instances attempted. In this work we develop the basic concepts of complexity theory. While doing so, we aim at presenting the … formal problem classes which are studied in complexity theory. …

New insights on the complexity of resource-constrained project scheduling: A case of single-mode scheduling

Schirmer, Andreas - 1996

Complexity proofs often restrict themselves to stating that the problem at hand is a generalization of some other intractable problem, This proof technique relies on the widely accepted assumptions that complexity results hold regardless of the model formulation used to represent the problem and...

New insights on the complexity of resource-constrained project scheduling: Two cases of multi-mode scheduling

Schirmer, Andreas - 1996

NP-completeness and other complexity proofs often merely State that the problem at hand is a generalization of some other intractable problem. This proof technique relies on the widely accepted assumption that complexity results hold regardless of the model formulation used to represent the...

Lot sizing and scheduling with sequence dependent setup costs and times and efficient rescheduling opportunities

Haase, Knut; Kimms, Alf - 1996

This paper deals with lot sizing and scheduling for a single-stage production System where setup costs and times are sequence dependent. A large bücket mixed integer programming (MIP) model is formulated which considers only efficient sequences. A tailor-made enumeration method of the...
