چکیده

A major financial expense for any military is the acquisition, operation, and maintenance of assets (e.g., vehicles, ships and aircraft), as well as training systems for those assets (e.g., combination of vehicles, vehicle simulators and other training systems). Even slight improvements in force structure efficiency can save governments large amounts of money or, using the same budget, can buy more capable or greater quantities of equipment. The uncertainty, multi-objectivity, and temporal dependence of military missions increase the complexity of military force structure problems. This complexity, coupled with high equipment costs, has driven the development (and application) of capability-based models using a spectrum of methods – from force structure computation to force structure evaluation. Models are capability-based, in that capabilities provided by assets are matched to capabilities required by scenarios (representing a variety of military missions) to be carried out by those assets (e.g., cargo and passenger capacities for airlift; anti-submarine warfare, anti-air warfare or surveillance for maritime fleets). In this paper, the merits of various models on the simulationoptimization continuum developed at Defence Research and Development Canada’s Centre for Operational Research and Analysis (DRDC CORA) are discussed, and how those methods can be useful for detailed asset mix evaluations or broad asset mix computations. Furthermore, given the huge computational complexity of using simulation models or simulation-based models within optimization frameworks (i.e., simulation within single-objective or multi-objective optimization), the use of approximate or surrogate models in optimizationbased asset mix computation and how optimization can be used to narrow down solutions to be more thoroughly analyzed within a simulation-based model are presented. Models used in past research will be described and relationships between these models will be outlined.

Design and Evaluation of a Method for Partitioning and Offloading Web-based Applications in Mobile Systems with Bandwidth Constraints

Computation offloading is known to be among the effective solutions of running heavy applications on smart mobile devices. However, irregular changes of a mobile data rate have direct impacts on code partitioning when offloading is in progress. It is believed that once a rate-adaptive partitioning performed, the replication of such substantial processes due to bandwidth fluctuation can be avoid...
