Financial returns to household inventory management
Baker, Scott; Johnson, Stephanie; Küng, Lorenz - 2020
Households tend to hold substantial amounts of non-financial assets in the form of inventory. Households can obtain … this inventory management. We demonstrate that households earn high returns from inventory management at low levels of … inventory, though returns decline rapidly as inventory levels increase. We provide evidence using scanner and survey data that …

Assigning orders to suppliers with linear piecewise concave costs
Corominas, Albert; Lusa, Amaia - In: Journal of Industrial Engineering and Management (JIEM) 12 (2019) 3, pp. 421-431
Purpose: Once a set of suppliers has been determined, according to criteria of quality, price and reliability, among others, there remains the problem of assigning orders to the selected suppliers, in order to cover the needs at the lowest cost. We consider the case in which the needs of a...

Fleet based schedule optimisation for product tanker considering shipʼs stability
Rizvanolli, Anisa; Haupt, Alexander; Müller, Peter Marvin - 2019
Purpose: Scheduling a fleet of product tankers in a cost effective and robust way to satisfy orders is a complex task. A variety of constraints and preferences complicate this attempt. Manual solutions as common in tramp shipping are not sufficient to deliver optimal and robust schedules....
