Manufacturers undergoing servitization resort to an increased number of suppliers to deliver services. Although managing upstream relationships is particularly critical in servitized contexts, theory development on this topic is still at an early stage. This study analyses the linkages between...

Intermittent demand items account collectively for considerable proportions of the total stock value of any organization. Forecasting the relevant inventory requirements constitutes a very difficult task and most work in this area is based on Croston’s estimator that relies upon exponentially...

This study compares three different scheduling policies in the Master Surgical Scheduling context with respect to three performance criteria: efficiency, i.e. the capability of scheduling a large number of surgeries; balancing, i.e. the capability to distribute workload fairly among the...

We study the multi-item economic lot scheduling problem (ELSP) with two sources of production: manufacturing of new items and remanufacturing of returned items. Manufacturing and remanufacturing operations are performed on the same production line. Tang and Teunter [2006. Economic lot scheduling...

In this paper, a capacity allocation problem is discussed based on a more complex supply chain than has been typically considered in previous quantitative modelling studies. This study analyses an integrated supply chain operation from raw material purchasing to final product distribution. The...

The Croston (1972. Forecasting and stock control for intermittent demands. Operational Research Quarterly 23, 289-303) method is the standard method for forecasting intermittent demand. It has been shown to perform well in various studies and is available in most commercial forecasting packages....

We analyze the classical inventory model with backordering, where the inventory position is controlled by an order level, order quantity policy. The cost for a backorder contains a fixed and a time-proportional component. Demand can be driven by any discrete process. Order lead times may be...
