One of the most important problems in the petroleum industry is the well-known petrol station replenishment problem with time windows, which calls for the determination of optimal routes by using a fleet of tank trucks to serve a set of petrol stations over a given planning horizon. In this...

We study the two-staged fixed orientation constrained two-dimensional two-staged cutting stock problem. We solve the problem using several approximate algorithms, that are mainly based upon a strip generation procedure (HESGA) already developed in ([13)]. We evaluate the performance of these...

This paper solves the binary single-constrained Knapsack Problem (KP) and undertakes a sensitivity analysis of its optimum solution. Given a knapsack of capacity c, and a set of n items, with each item j, j = 1,…,n, characterised by a weight wj and a profit pj, the binary...
