The article presents a continuous time inventory model with known time varying demand. The relevant costs are the carrying and replenishment costs; backlogs are prohibited, replenishments are instantaneous, and the planning horizon is finite and known, The problem is to find the optimal schedule...

A maximum likelihood approach for the analysis of stochastic volatility models is developed. The method uses a recursive numerical integration procedure that directly calculates the marginal likelihood. Only conventional integration techniques are used, making this approach both flexible and...

The objective of this article is to give a concise report on a project to achieve an optimal operation of a public transportation network by the application of modern mathematical programming methods and computing techniques. The paper delineates the formulation of a mathematical model of a...

The problem of allocating customers of different types to various channels of a service system is considered. Service times are assumed to be independent identically distributed random variables whose distribution functions depend on the type of customers as well as the service channel. The...
