The paper studies the interaction between the monetary and fiscal authorities in the Euro area and the block of outside countries during the Third Stage of EMU. Restraints on fiscal policies and outside monetary policy are introduced as utility costs related to the use of the tax instruments...

Following up on the suggestions of Adolph Lowe, the paper investigates the potential contribution of pragmaticist philosopher Charles Sanders Peirce's concept of "retroduction" (and especially Norwood Hanson's elaborations of that concept), mathematician George Polya's work on heuristics,...

We consider here a NP-hard problem related to the Routing and Wavelength Assignment (RWA) problem in optical networks, dealing with Scheduled Lightpath Demands (SLDs). An SLD is a connection demand between two nodes of the network, during a certain time. Given a set of SLDs, we want to assign a...

In this paper, we consider the combined distribution and assignment (CDA) problem with link capacity constraints modeled as a hierarchical logit choice problem based on random utility theory. The destination and route choices are calculated based on the multi-nominal logit probability function,...

Curriculum design is a highly important activity for the academic institutions. It is discussed in literature as a balancing academic curriculum problem (BACP). The BACP schedules courses to different semesters, while balancing the total workload per period. BACP model involves precedence...

In this work we consider scheduling problems where a sequence of assignments from products to machines – or from tasks to operators, or from workers to resources – has to be determined, with the goal of minimizing the costs (=money, manpower, and/or time) that are incurred by the interplay...

We prove existence of envy-free allocations in markets with heterogenous indivisible goods and money, when a given quantity is supplied from each of the goods and agents have unit demands. We depart from most of the previous literature by allowing agents' preferences over the goods to depend on...
