We sketch the integral transform method in a close connection with its historical development and survey newer applications to problems in production economics and finance.

It is a well-known fact that inventory research has its roots in the monetary theory. In this note we sketch the interaction between inventory theory and finance today. We consider the development from a simple deterministic model to continuous-time

This paper has a double purpose. First, it provides a historical analysis of the developments leading to the first “Stanford Studies”, a collection of papers which probably can be considered even today as the single most fundamental reference in

In this article we analyze a static urban transportation system illustrated with the problems facing the routing of a garbage-collecting fleet in the City of Leipzig taking ecological data into account. We use a conceptually straightforward approach

In multistage production systems under uncertainty as well as in local decentralized stochastic inventory control systems, there are often easily described external demand processes and a very complex internal demand depending on the structure of the

in this note we study the dependency of the Gittins index on the parameters of the diffusion and Brownian bandits. We formulate the continuous time two-armed bandit problem within the framework of the two-parameter stochastic processes. 1 o assess ex

This paper is concerned with a resetting model, where the states of the underlying dynamic system are to be kept inside a tolerance region around a standard level. Under some assumptions on the dynamic behaviour, the tolerance region and different co

This paper considers Markovian decision processes in discrete time with transition probabilities depending on an unknown parameter which may change step by step. In the case of the convergence of such a parameter sequence, a policy maximizing the ave

In this note continuous review multiproduct inventory models are considered. Conditions ensuring the optimality of simple policies which are closely related to Johnson's (σ, S) policies in the periodic review case are given.
