This paper concerns a class of maximum covering location problems in networks in uncertain environments. It is assumed that: (a) relative weights of demand nodes are either deterministic or imprecise, described by linguistic expressions, (b) potential facility site locations are limited to network nodes. The concept of coverage is extended to include a degree of node coverage which means that t...
There exist various service systems that have hierarchical structure. In hierarchical service networks, facilities at different levels provide different types of services. For example, in health care systems, general centers provide low-level services such as primary health care services, while the specialized hospitals provide high-level services. Because of demand congestion in service networ...
From the mid-1980s to the mid-1990s, the proportion of non-elderly Americans with employment-based health insurance declined. Roughly 80% of this decline was due to the loss of coverage by dependent family members. During this period, workers became increasingly responsible for the costs of family coverage, while expanded Medicaid coverage provided low-income working families with an alternativ...
In this paper, we introduce a new generalization of the classical planar maximum coverage location problem (PMCLP) in which demand zones and service zone of each facility are represented by two-dimensional spatial objects such as circles, polygons, etc. In addition, we allow partial coverage in the foregoing generalization, i.e., covering only part of a demand zone is allowed and the coverage a...
This paper empirically assesses the selection effects and determinants of the demand for supplemental health insurance that covers hospital and dental benefits in Germany. Our representative dataset provides doctor-diagnosed indicators of the individual’s health status, risk attitude, demand for medical services and insurance purchases in other lines of insurance as well as rich demographic and...
We use the German Socio-Economic Panel (GSOEP) to analyze determinants of the demand for supplemental health insurance covering hospital and dental in Germany. The GSOP dataset provides doctor diagnosed indicators of the individual’s health state, risk attitude, and demand for medical services and insurance purchases in other lines of insurance as well as rich demographical and socioeconomical ...
The work reported here assesses the coverage achieved by two sales-based approaches to distributing a complementary food supplement (KOKO Plus™) to infants and young children in Ghana. Delivery Model 1 was conducted in the Northern Region of Ghana and used a mixture of health extension workers (delivering behavior change communications and demand creation activities at primary healthcare center...
We study the planar maximum coverage location problem (MCLP) with rectilinear distance and rectangular demand zones in the case where “partial coverage” is allowed in its true sense, i.e., when covering only part of a demand zone is allowed and the coverage accrued as a result of this is proportional to the demand of the covered part only. We pose the problem in a slightly more general form by ...
