We consider a robotic flowshop model in which a single robot is responsible for the transportation of parts between machines and the amount of time that a part spends on a machine must be comprised in some predefined interval. The objective is to find a feasible schedule with minimal cycle time....

The Stackelberg pricing problem has two levels of decision making: tariff setting by an operator, and then selection of the cheapest alternative by customers. In the network version, an operator determines tariffs on a subset of the arcs that he owns. Customers, who wish to connect two vertices...

Technological innovations and growing consumer demand have led to a variety of design and expansion problems in telecommunication networks. In particular, local access net- works have received a lot of attention, since they account for approximately 60% of total investments in communication...

Wireless communication is used in many different situations such as mobile telephony, radio and TV broadcasting, satellite communication, and military operations. In each of these situations a frequency assignment problem arises with application specific characteristics. Researchers have...

We develop an algorithm that solves the constant capacities economic lot-sizing problem with concave production costs and linear holding costs in O(T³) time. The algorithm is based on the standard dynamic programming approach which requires the computation of the minimal costs for all possible...

This paper investigates the relationship between corporate culture and market orientation using a different methodology to those usually found done in empirical studies on this topic. Conventionally, one or two key informants provide information on the firm’s marketing practices in large scale...

Over de verhouding tussen overheid en markt wordt steeds vaker de grootst mogelijk onzin verkondigd. Dat gebeurt niet alleen in de universitaire (economische) wetenschap, maar vooral ook in de politieke wereld van de beleidsmakers. Dat heeft fatale gevolgen voor ons wetenschappelijk denken over...

The Internet revolution has led to significant changes in the way travel agencies interact with customers. Travel websites are used to different degrees, and for a variety of combinations of pre-transaction, transaction and post-transaction services. A better understanding of how customers...

A convenient way to find out how things are going is by taking a look at your neighbours. In this paper we develop a method for the evaluation of regional economic performance based on an input-output (IO) framework. Once we defined economic criteria for measuring this performance, such as real...

In this study we investigate whether the process of Attraction Selection and Attrition as described by Schneider (1984) is already operative prior to labor market entry, i.e., in the educational phase of careers. We focused on selection with regard to the locus of control personality trait...
