Considerable efforts have been dedicated to models that describe how consumers make purchase decisions. Within this vast area of research we review stochastic approaches to consumer behaviour, i.e. probabilistic laws relating the observed strings of consecutive purchases to explanator variables. We start out by discussing the basic concepts underlying this field. Then we deal with models concentrating on brand choice, whereby we trace the development from the early ideas in the Fifties to today's sophisticated models. Subsequently we turn to the Negative Binomial Distribution, the 'classical purchase incidence model, and its extensions. Then we describe combined purchase timing-brand selection models and introduce models of store choice and purchase quantity selection. After briefing on estimation and validation methods for stochastic models we finally critically review the state-of-the-art in this field. Special emphasis is placed on empirical applications throughout the review. , Elsevier Science Publishers B.V. (North-Holland) 2 Cl. Wagner, A.

This research firstly analyzes the stakeholders' characteristics and relations in the Chinese highway freight transport market. Based on the different information requirements found and the current market situation, a framework for a Chinese highway freight transport platform

Demand and procurement planning for consumer electronics products must cope with short life cycle... more Demand and procurement planning for consumer electronics products must cope with short life cycles, limited replenishment opportunities and a willingness to pay that is influenced by past prices and decreases over time. We therefore propose the use of an integrated pricing and inventory control model with a two-period linear demand model, in which demand also depends on the difference between a pricehistory-based reference price and the current price. For this model we prove that the optimal joint pricing/inventory policy for the replenishment opportunity after the first period is a base-stock list-price policy. That is, stock is either replenished up to a base-stock level and a list-price is charged, or it is not replenished and a discount is given that increases with the stock-level. Furthermore, we use real-world cell phone data to study the differences between an integrated policy and traditional sequential optimization, where prices are initially optimized based on the expected demand and ordering cost, and the resulting demand distribution is used to determine an optimal inventory policy. Finally, we discuss possible extensions of the model.

The market situation in 2005 was highly competitive and dynamic, resulting in relatively short tariff life cycles. Excessively long lead times made tele.ring's management feel dissatisfied with their new tariff development process. Furthermore, a new competitor had entered the market, posing a major threat, and

In this paper, we discuss the practical advantages of such techniques for the selection of a software platform. First, we argue that traditional quantitative approaches to a cost-benefit analysis give only a partial picture of such decision situations: due to the long planning horizon required because of the time-consuming and resource-intensive implementation process, it is not possible to exactly predict which applications will, in fact, run on the system over time. Thus, the investor is faced with the problem of valuing "implementation opportunities." We then compare different valuation techniques for this task and discuss their respective advantages and drawbacks. The practical advantages of employing such models are demonstrated by describing a real-life case study where option pricing models were used for deciding whether to continue employing SAP R/2 or to switch to SAP R/3.
