We estimate and analyse the hazard rates of members of the supervisory board in German leading companies, listed in the DAX, with a special focus on personal interdependencies with other supervisory boards and executives committees. We find fundamental differences between supervisory board...

We consider a production-inventory planning problem with time-varying demands, convex production costs and a warehouse capacity constraint. It is solved by use of the Lagrangian form of the maximum principle. The possible existence of strong decision and forecast horizons is demonstrated. When...

This paper is concerned with a generalization of classical inventory models (with fixed ordering costs) that exhibit (s, S) policies. In our model, the distribution of demands in successive periods is dependent on a Markov chain. The model includes the case of cyclic or seasonal demand. The...

Recently, the production control problem in stochastic manufacturing systems has generated a great deal of interest. The goal is to obtain production rates to minimize total expected surplus and production cost. This paper reviews the research devoted to minimum average cost production planning...

This paper is concerned with a periodic-review inventory system with three consecutive delivery modes (fast, medium, and slow) and demand forecast updates. At the beginning of each period, the inventory level and demand information are updated and decisions on how much to order using each of the...

We present a classified bibliography of the literature in the area of forecast, solution, and rolling horizons primarily in operations management problems. Each one of over 200 selected papers is categorized on five dimensions that identify the horizon type, the model type (deterministic or...

Why is understanding replacement purchases of consumer durables so important? It is the sales of replacement units that will ensure their long-term success. Replacement sales account for more than 75% of total sales for many durables (Islam and Meade 2000). Thus, the accurate modeling of...

Market orientation has evolved into a key construct in the marketing and strategy literature. While much progress has been made in empirical research, the concept lacks a coherent theoretical underpinning. This paper contributes to existing marketing research by proposing a theoretical...
