Uncapacitated plant location under alternative spatial price policies
Article Abstract:
Facility location modelling typically is developed with an assumption of clients' fixed requirements for a company's output, while economic theory and casual observation suggest that clients' demand is price-sensitive and changes with the price set by the firm. Optimal plant locations are dependent on a firm's pricing policy and an optimization model should integrate cost and demand factors in determining the optimal locations for a firm's plants. The model must recognize the interaction of pricing and demand and specify the firm's spatial price policy: uniform mill pricing; uniform delivered pricing; or spatial discriminatory pricing. An optimization model based on an algorithm that solves the optimization problem has been developed for a generalized version of uncapacitated facility location that encompasses the three price policies.

Screening women of child-bearing age for human immunodeficiency virus: a model-based policy analysis
Article Abstract:
A cost-benefit analysis is made of a human immunodeficiency virus (HIV) screeningpolicy involving women of childbearing age. A model of the HIV epidemic provides the analytical framework, which includes time-based disease transmission and progression; behavioral changes; screening, counseling and education effects; and total population impact. The results suggest that the main benefit of such a policy lies in the prevention of adult infection throughcontact, rather than in the protection of their offspring from infection. Screening of medium- to high-risk women is found to be cost-beneficial, in contrast to screening of low-risk candidates. However, screening regardless of risk characteristics may also yield returns when screened women exhibit relatively low levels of behavioral change.

An overview of representative problems in location research
Article Abstract:
Fifty representative business location problems are reviewed with an emphasis on their formation and their relationships to each other. Most of the representative problems have had operations research-type models developed for them and many are formulated as optimization problems. The review includes an analysis of new innovative models, and traditional models, such as center, median, and warehouse location problems.
