Minimizing Resource Availability Costs in Time-Limited Project Networks

Demeulemeester, Erik - In: Management Science 41 (1995) 10, pp. 1590-1598

We consider the problem of minimizing renewable resource availability costs in an activity-on-the-node project network subject to a project due date. Project activities have fixed durations and may require the use of multiple renewable resources in constant amounts throughout their duration....

Implicit Treatment of "Zero or Range" Constraints in a Model for Minimum Cost Foundry Alloys

Hansen, P.; Hugé, J. - In: Management Science 35 (1989) 3, pp. 367-371

specified composition. We show that such problems, of realistic size, can be solved optimally by mixed-integer programming … a similar way as lower and upper bounds are treated implicitly in bounded variables linear programming. Computation …

Product Positioning Under Price Competition

Choi, S. Chan; Desarbo, Wayne S.; Harker, Patrick T. - In: Management Science 36 (1990) 2, pp. 175-199

This paper presents a consumer-based methodology for new product pricing and positioning in the face of price competition. The price competition is modelled as a Nash equilibrium for which two complementary approaches are employed: an analytical approach of duopoly provides qualitative insights...

Anti-industrial pollution efficiency using DEA with constrained emission

Wu, Dexiang; Liang, Liang - In: International Journal of Global Energy Issues 32 (2009) 4, pp. 372-379

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.

Optimal Flexibility Configurations in Newsvendor Networks: Going Beyond Chaining and Pairing

Bassamboo, Achal; Randhawa, Ramandeep S.; Mieghem, Jan … - In: Management Science 56 (2010) 8, pp. 1285-1303

We study the classical problem of capacity and flexible technology selection with a newsvendor network model of resource portfolio investment. The resources differ by their level of flexibility, where "level-k flexibility" refers to the ability to process k different product types. We present an...

The U. S. PV program: Now and the year 2000

Rannels, James E. - In: Renewable Energy 8 (1996) 1, pp. 72-76

There will be a vigorous U.S. Photovoltaic (PV) program in 2000, despite the current turmoil and debate over the size and legitimate role of nearly every aspect of the Federal government. There are two fundamental reasons why there will still be an active Federal role in PV development in the...
