This paper studies the performance of static and real-time scheduling approaches in vehicle-based internal transport (VBIT) systems, which can be found in manufacturing and warehouse facilities. We propose three heuristic approaches for static VBIT problems (insertion, combined and column...

Over the last decade we have witnessed the rise and fall of the so-called new economy stocks. One central question is to what extent these new firms differ from traditional firms. Empirical evidence suggests that stock returns are not normally distributed. In this article we investigate whether...

We decompose the conditional expected mutual fund return in five parts. Two parts, selectivity and expert market timing, can be attributed to manager skill, and three to variation in market exposure that can be achieved by private investors as well. The dynamic model that we use to estimate the...

In this paper, we analyze the economic value of predicting stock index returns as well as volatility. On the basis of simple linear models, estimated recursively, we produce genuine out-of-sample forecasts for the return on the S&P 500 index and its volatility. Using monthly data from 1954 to...

We present an analysis of the performance of the DAX, German's major stock market index, over the last two years. Our analysis is broader than conventional benchmark approaches because we study the properties of all feasible portfolios, i.e. portfolios composed given the same investment...

Empirical research has demonstrated that a market orientation has in general a positive effect on organizational performance. The potential benefits of a market orientation have, however, not been realized because academics and practitioners do not yet understand the modus operandi that...

This paper examines the ability of balanced pension plan managers to successfully time the equity and bond market and select the appropriate assets within these markets. In order to evaluate both market timing abilities in these balanced pension plans, we extend the traditional equity market...

When delegating an investment decisions to a professional manager, investors often anchor their mandate to a specific benchmark. The manager’s exposure to risk is controlled by means of a tracking error volatility constraint. It depends on market conditions whether this constraint is easily...

Order picking has long been identified as the most labour-intensive and costly activity for almost every warehouse; the cost of order picking is estimated to be as much as 55% of the total warehouse operating expense. Any underperformance in order picking can lead to unsatisfactory service and...
