We have developed a hardware detour path selection facility for the Hitachi SR2201 parallel computer, which uses a multi-dimensional crossbar as an inter-processor network to ensure operating efficiency and high reliability when a part of the network is faulty. When this hardware facility is used, packets are transmitted to their destination along alternative paths to avoid the fault. However, ...

In this paper we formalize and initiate the study of heterogeneous k-facility location without money, a problem akin to the classical k-facility location problem but encompassing a richer model and featuring multi-parameter agents. In particular, we consider truthful mechanisms without money for the problem in which heterogeneous (i.e. serving different purposes) facilities have to be located a...

Capacitated p-median problem (CPMP) is a well-known facility-location problem, in which p capacitated facility points are selected to satisfy n demand points in such a way that the total assigned demand to each facility does not exceed its capacity. Minimizing the total sum of distances between each demand point and its nearest facility point is the objective of the problem. Developing an effic...

In this paper, a mathematical model for the strategic planning and design of supply chains in the globalization context is proposed. A multi-objective function is used to address decisions about capacity sizing, sourcing, and facility location, with the scope of maximizing supply chain profits. The model is dynamic and is applied to a multiechelon, multi-facility and multi-product supply chain ...

We propose an explanation facility for a qualitative preference representation framework. We show how an explanation can be provided for qualitative, multi-criteria preferences based on the criteria that are used to decide preferences between outcomes. Such a facility provides an important tool for a user to understand how preferences are determined. We show that this facility can also be used ...

In this paper a new evolutionary approach for solving the multi-level uncapacitated facility location problem (MLUFLP) is presented. Binary encoding scheme is used with appropriate objective function containing dynamic programming approach for finding sequence of located facilities on each level to satisfy clients’ demands. The experiments were carried out on the modified standard single level ...

BACKGROUND Master facility lists (MFL) maintain an important standard (unique identifier) in country health information systems that will aid integration and interoperability of multiple health facility based data sources. However, this standard is not readily available in several low and middle income countries where reliable data is most needed for efficient planning. The World Health Organiz...
