One of the basic combinatorial optimization problems is the assignment problem that deals with assigning jobs to individuals. In traditional assignment problems, n jobs usually assign to n individuals such that the total cost is minimized or the total profit is maximized. However, in numerous real-life applications, various attributes could be considered in assignment problems while data (obj...

intentional assignment of entitlements (as opposed to debts) is a legal institution which is based on the possibility of separation of entitlements from the personality of creditor and of its assignment to a third party. in the voluntary assignment of entitlements, the creditors may assign their rights to a third party. after long discussions, voluntary assignment of rights has been accepted in...

This paper describes a polynomial transformation for a class of unit-demand vehicle routing problems, named node-balanced routing problems (BRP), where the number of nodes on each route is restricted to be in an interval such that the workload across the routes is balanced. The transformation is general in that it can be applied to single or multiple depot, homogeneous or heterogeneous fleet BR...

The paper presents experimental results on quadratic assignment problem. The “scanning area” method formulated for radioelectronic equipment design is applied. For all more complex tests ours results are better or coincident with the ones known in literature. Conclusion concerning the effectiveness of method are given.

Assignment of aircraft types, each having different seat capacity, operational expenses and availabilities, critically affects airlines’ overall cost. In this paper, we assign fleet types to paths by considering not only flight timing and passenger demand, as commonly done in the literature, but also operational expenses, such as fuel burn and carbon emission costs associated with adjusting the...

Although air transport contributes to globalization, airline emissions have attracted focus in green logistics. In this work, we investigate the airline-fleet assignment problem from a risk-averse perspective which uncertain demand and fuel price are considered simultaneously. The objective is maximise total profit fashion, i.e., weighted sum of expected conditional value at risk profit. An app...
