The supply problem of an integrated oil company comprises the allocation of crude oils to refineries, the calculation of refinery programmes and the transportation of finished products to the market.

5. Structure of Linear Programming Model Generally, all LP problems [3] [17] [29] [31] [32] have these three properties in common: 1) OBJECTIVE FUNCTION: The objective function of an LPP (Linear ...

An example of the quadratic assignment problem (QAP) is the facility location problem, in which n facilities are assigned, at minimum cost, to n sites. Between each pair of facilities, there is a ...

In this paper, we solve a residing combinatorial optimization problem commonly known as graph-based pairwise assignment, maximum bipartite cardinality matching, min-cut, or max-sum problem by the ...

They started their research by formulating the problem into a standard linear programming problem (LPP), therefore, slack variables are added to constraints. They used WinQSB user-tool program to ...

This course continues our data structures and algorithms specialization by focussing on the use of linear and integer programming formulations for solving algorithmic problems that seek optimal ...

The routing and spectrum assignment problem is an NP-hard problem that receives increasing attention during the last years. Existing integer linear programming models for the problem are either very ...
