A major challenge for the European electronic industry is to enhance productivity while reducing costs and ensuring quality in development, integration and maintenance. Model-Driven Engineering (MDE) principles and techniques have already shown promising capabilities but still need to scale to support real-world scenarios implied by the full deployment and use of complex electronic components and...
The purpose of this study is to create a model of a relationship in which the dependent variable is the result of a project and the independent variables are the characteristics of human resources. We attempted a comparative evaluation of discriminant analyses with a statistical model and a machine learning model using assessments of the results of projects and team characteristics derived from questionnaire...
Recently, China economy has entered the stage of “new normal”, series of reforms and the steady growth of economy boost the rapid development of China securities industry. In this paper, we designed a Data Envelopment Analysis (DEA) Model with multi inputs and outputs, and statically and dynamically evaluated the firms and the industry. Our findings indicated that in the period of “new normal”, there...
Effective evaluation of the productivity and safety of manual operations is essential for successful planning of operations as well as for workplace design. However, actions employed by production planners to improve productivity might adversely impact the ergonomic safety of workers. To address this issue, methods and tools are required that enable simultaneous evaluation of the efficiency and safety...
We consider the Erlang A model, a queuing model often applied to analyze call center performance. While not a new model, Erlang A is becoming a popular alternative to the widely used Erlang C model. In this paper we analyze the accuracy of Erlang A predictions in high traffic environments, a situation where the Erlang C model is not applicable. Our findings indicate that in this high traffic region...
Agent based simulation modelers have found it difficult to build grounded fine grained simulation models of human behavior. By grounded we mean that the model elements must rest on valid observations of the real world, by fine grained we mean the ability to factor in multiple dimensions of behavior such as personality, affect and stress. In this paper, we present a set of guidelines to build such...
Hiring workers under seasonal recruiting contracts causes significant variation of workers skills in the vineyards. This leads to inconsistent workers performance, reduction in harvesting efficiency, and increasing in grape losses rates. The objective of this research is to investigate how the variation in workers experience could impact vineyard harvesting productivity and operational cost. The complexity...
The increasing importance of services in high-wage countries calls for a detailed examination of service productivity and complexity in current research projects. This paper describes the development of a measurement model with regard to service productivity and complexity of emergency medical services. While the measurement model of service productivity is partly literature-based, a novel construct...
This study illustrates an estimation tool for software test that provides the estimated time and the cost of any sort of software test project. There are different well-recognized estimation tools for software development process [9], however, there remains a lack of standard tools for estimation of Software Test phase. Therefore, the authors developed a web base tool (www.4beats.net/tpet/) in order...
Software reuse is the use of already existing concepts, objects or software components to build new software. The goal of software reuse research is to explore systematic procedures for developing new systems from existing ones. The systematic software reuse is the most effective way to improve software development. Domain engineering plays crucial role in Software Reuse research, which makes the...
There is considerable variation in growth and structure between individuals of Sitka spruce (Picea sitchensis). Both genetic and environmental factors contribute to this variation and an explanation for their joint effects is given based upon the dynamics of their interaction in the production and utilization of photosynthate by the growing tree. Whole tree attributes, such as high individual biomass...
Integrated circuit (IC) chip fabrication consists of hundreds of complicated and time-consuming processing steps like wafer processing, testing and packaging. However, it is hard to achieve the efficiency and output while maintaining the high product quality and reducing overall costs simultaneously in the complexity of semiconductor manufacturing. In order to achieve the low cost manufacturing via...
Performance represents the completion of activities, programs, or policies to achieve the objectives, visions, and missions of organizations. The National Library of Indonesia is a government organization which provides public services. To improve its functions, the National Library established Electronic Library (E-Library) toward Information and Communication Technology (ICT) infrastructure aspect...
We consider a two-machine-one-buffer production system with each machine's condition following a certain degradation process. An analytical model of the integration of machine condition degradation and productivity is introduced. Analytical methods based on the Markov chain approach are developed to quantify the interaction between machine condition degradation process and the overall system performance...
Telecom regulatory departments issued many policies to keep the healthy development of telecom assets market, while the governments pay little attention to the resource configuration of telecom assets, and some of the existing researches have not got verified in academia. In this paper, firstly it puts forward the evaluation model for resource configuration of telecom assets, and indicators of cause...
Colombia has survived a war for over half century, confrontation of civil society, guerrilla, paramilitary and our armed forces causing death and pain. Today we are close of achieving a peace agreement. USA President Barack Obama, The UN Office, The Catholic Church Pope Francisco and many other Governments and Organizations have expressed great support to our agreement. However, no serious studies...
The complexity of the social problems in Higher Education (HE) is derived from the dynamic nature of the same education system and how the universities evolve; they have been focused on the poor levels of quality, competitiveness and productivity, with a high incidence in quality and elevated costs in the HE in Colombia for government and families. A solution space is presented with the creative development...
Software productivity is influenced by how efficiently programmers execute tasks assigned to them. For executing a task, programmers execute several steps. How the execution of these steps is organized by a programmer is referred to as task process. While overall software process has been well studied, the impact of task processes has not been studied much. In this work, we study the impact of task...
This paper discusses models and methods for the analysis of PV systems with Distributed Maximum Power Point Tracking (DMPPT). An Energy Productivity Analysis Algorithm (EPAA) is discussed, integrating models and algorithms from component level to system level, allowing the analysis of PV systems operating in partial shading and electrical mismatched conditions. The EPAA provides realistic assessment...
Improving service quality in the banking sector is essential for customer satisfaction. Decision makers are especially concerned about the time that customers wait before receiving their service. To stay competitive, decision makers have to continuously improve their service quality, measured in terms of suitable performance indicators. In this study, we focus on modelling and analysis of bank queuing...
