Time pressure is a familiar phenomenon. The quantity of spare time people have clearly effects their satisfaction with their leisure and with their life as a whole. But so too, we show, does how much control people have over how much spare time they have. We measure this through an indicator of ‘discretionary time’, which proves to be equally or more important than spare time itself in these co...

In the book “Optimal inventory modeling of systems: multi-echelon techniques” the author Craig Sherbrooke, who has developed several important model in this area, describes a part of the model cosidered in this manuscript as follows (in “aircraft language”): “When a malfunction is diagnosed on an aircraft, the malfuncioning item is removed from the aircraft and brought into base supply. If a sp...

We analyze the integrated tactical capacity planning of spare parts supply and workforce allocation in maintenance logistics of advanced equipment. The equipment time-to-failure, spare parts replenishment time, and equipment repair time are random and independent of each other.

in this paper a new problem of three stage disassembly-assembly scheduling is introduced and reviewed. this problem, which was arisen from the aviation industry characteristics, is a generalization of the two stage assembly scheduling problem. products (helicopters) in the aviation industry return to assembler for annual overhaul repair services. in the first stage helicopters are disassembled ...

This thesis studies an inventory-location problem faced by a large manufacturer and supplier of small to medium sized aircraft and their spare parts. The sale of after market spare parts is a major source of revenue for the company, but it is a complex industry with many unique challenges. The original problem is a multi-echelon network design problem, which is decomposed into a facility locati...

This paper investigates the gap between research and practice in spare parts management, with specific reference to durable goods addressed to private or professional customers. The paper provides a critical literature review of theoretical contributions about spare parts classification and demand forecasting for stock control. The discussion of ten case studies, then, allows to analyze the rea...

Physicists love emergence. From a welter of complex details about a system's constituents, simple and universal rules sometimes emerge that adequately describe the collective behavior of the components. Even if these rules are not completely universal, they often have only a few relevant parameters, a vast simplification compared to the many that describe the constituents individually. But as V...
