We consider the optimal allocation of a resource in a single-facility production environment in the presence of capacity-based economies and diseconomies of scope. This setting generalizes the usual approach to single-facility resource allocation by allowing for the effective capacity of a...

In this paper, we develop a Lagrangean relaxation-based heuristic procedure to generate near-optimal solutions to very-large-scale capacitated lot-sizing problems (CLSP) with setup times and limited overtime. Our computational results show that large problems involving several thousand products...

The minimum spillage sequencing problem, which arises in real-time satellite signal data processing, requires a set of numbers to be arranged so as to minimize the "overflow" of the partial sums above an upper bound. We subject several heuristics to worst-case analysis, average-case analysis,...

In this paper a branch-and-bound procedure is described for scheduling the activities of a project of the PERT/CPM variety subject to precedence and resource constraints where the objective is to minimize project duration. The procedure is based on a depth-first solution strategy in which nodes...

DEA model is employed to estimate the anti-industrial pollution efficiency with constrained emission. This is a new set of DEA models with the sum of outputs of all DMUs being fixed. The developed DEA is used to compute anti-industrial pollution efficiency in all major cities of a province in China.
