A planner may use simulation for in the analysis and design of construction operation processes to optimize overall performance of a construction system. Normally, the basic elements used in construction operation process simulation system such as CYCLONE (CYCLic Operation NEtworks) are activities and queues. Activity is used to model the execution of the task work which consumes resources and ...

This chapter deals with hierarchical model predictive control (MPC) of distributed systems. A three level hierarchical approach is proposed, consisting of a high level MPC controller, a second level of so-called aggregators, controlled by an online MPC-like algorithm, and a lower level of autonomous units. The approach is inspired by smart-grid electric power production and consumption systems,...

Virtualization is the cornerstone technology of cloud computing. Advancements in virtualization enable researchers to tackle key challenges in today’s cloud. The first part of this thesis delves into the emerging container virtualization and how leveraging containers we address resource management and pricing challenges in the cloud. We try calling for an end to the constant battle between publ...

When testing a set of data for randomness according to a probability distribution that depends on a parameter, access to this parameter can be considered as a computational resource. We call a randomness test Hippocratic if it is not permitted to access this resource. In these terms, we show that for Bernoulli measures μp, 0 6 p 6 1 and the Martin-Löf randomness model, Hippocratic randomness of...

Resource management is a key challenge that service providers must adequately face in order to ensure their profitability. This paper describes a proof-of-concept framework for facilitating resource management in service providers, which allows reducing costs and at the same time fulfilling the quality of service agreed with the customers. This is accomplished by means of virtualization, by pro...

introduction: human resources development is one of the most important components of any organization and detecting important factors influencing human resources management plays an essential role in the success of the firms. in this study, we investigated different factors influencing human resources productivity of shiraz university of medical sciences staff. method: the present research was ...

The studies we present investigate elementary students’ reasoning about distributions in two contexts: (a) measurement and (b) naturally occurring variation. We first summarize an investigation in which fourth-graders measured the heights of a variety of objects and phenomena, including the school’s flagpole, a pencil, and several launches of model rockets. Students noted that the measurements ...

This paper aims to determine emissions polluted directly and indirectly by an average person, for each household type, across a wide range of emissions. There are five household type categories: location, income decile, household composition, size and number of disabled residents. Ireland's Sustainable Development Model (ISus) is used which allows the analysis of direct and indirect sources of ...

As recently pointed out by the Institute of Medicine, the existing pandemic containment and mitigation models lack the dynamic decision support capabilities. We present two simulation-based optimization models for developing dynamic predictive resource distribution strategies for cross-regional pandemic outbreaks. In both models, the underlying simulation mimics the disease and population dynam...
