The deployment of edge computing infrastructure requires a careful placement the servers, with an aim to improve application latencies and reduce data transfer load in opportunistic Internet Things systems. In server placement, it is important consider capacity, available budget, hardware requirements for servers underlying backbone network topology. this paper, we thoroughly survey existing li...

It is well known that optimal server placement is NPhard. We present an approximate model of content distribution network for the case when both clients and servers are dense, and propose a simple server allocation and placement algorithm based on highrate quantization theory. The key idea is to regard the location of a request as a random variable with probability density that is proportional ...

Location-allocation modeling has always been regarded as a core part of spatial analysis. A review the literature, however, reveals that, nevertheless, publications related to facility location disappeared almost completely from geographic journals in meantime. It can be assumed that one major reason for this development is limited capability location-allocation modules implemented GIS packages...

Assignment model is a powerful operations research techniques that can be used to solve assignment or allocation problem. This study applies the assignment model to the course allocation problem in Nigeria tertiary institution in order to maximize lecturers’ effectiveness. A well-structured questionnaire was used to obtain data from lecturers and solved with Hungarian method. The study revealed...

SUMMARY Purpose: study optimization location-allocation of emergency shelter for Earthquake after destructive earthquake disaster, so as to prevent or reduce the damage caused by the earthquake and its secondary disasters, to guide the resettlement and reconstruction of post-disaster. Methods: basis on GIS, by applying the location-allocation optimization of P-center model of geographical space...
