A DEA-BASED APPROACH TO RANKING MULTI-CRITERIA ALTERNATIVES
KÖKSALAN, MURAT; TUNCER, CEREN - In: International Journal of Information Technology & … 08 (2009) 01, pp. 29-54
We propose a data envelopment analysis (DEA)-based approach to ranking multi-criteria alternatives. We call it "the area of the efficiency score graph" (AES) approach. Unlike the classical DEA score and Dk measure that counts the number of DMUs (alternatives in DEA terminology) that should be...

An aggressive reduction scheme for the simple plant location problem
Letchford, Adam N.; Miller, Sebastian J. - In: European Journal of Operational Research 234 (2014) 3, pp. 674-682
Pisinger et al. introduced the concept of ‘aggressive reduction’ for large-scale combinatorial optimization problems. The idea is to spend much time and effort in reducing the size of the instance, in the hope that the reduced instance will then be small enough to be solved by an exact...

Minimizing the maximum travel time in a combined model of facility location and network design
Contreras, Ivan; Fernández, Elena; Reinelt, Gerhard - In: Omega 40 (2012) 6, pp. 847-860
This paper presents a combined Facility Location/Network Design Problem which simultaneously considers the location of facilities and the design of its underlying network so as to minimize the maximum customer-facility travel time. The model generalizes the classical p-center problem and has...

The directed profitable location Rural Postman Problem
Arbib, Claudio; Servilio, Mara; Archetti, Claudia; … - In: European Journal of Operational Research 236 (2014) 3, pp. 811-819
In this paper we introduce an extension of the well known Rural Postman Problem, which combines arc routing with profits and facility location. Profitable arcs must be selected, facilities located at both end-points of the selected arcs, and a tour identified so as to maximize the difference...

True Interest Cost in Municipal Bond Bidding: An Integer Programming Approach
Nauss, Robert M. - In: Management Science 32 (1986) 7, pp. 870-877
Over $47 billion of tax exempt debt issues were sold to the public in 1982. A portion of this total was offered to municipal bond underwriters under a competitive bidding system using the criterion of minimum true interest cost (internal rate of return). The TIC bidding problem may be formulated...

Simultaneous production and logistics operations planning in semicontinuous food industries
Kopanos, Georgios M.; Puigjaner, Luis; Georgiadis, … - In: Omega 40 (2012) 5, pp. 634-650
The production and logistics operations planning in real-life single- or multi-site semicontinuous food industries is addressed in this work. A discrete/continuous-time mixed integer programming model, based on the definition of families of products, is developed for the problem in question. A...

Trade-offs Between Customer Service and Cost in Integrated Supply Chain Design
Shen, Zuo-Jun Max; Daskin, Mark S. - In: Manufacturing & Service Operations Management 7 (2005) 3, pp. 188-207
When designing supply chains, firms are often faced with the competing demands of improved customer service and reduced cost. We extend a cost-based location-inventory model (Shen et al. 2003) to include a customer service element and develop practical methods for quick and meaningful evaluation...
