A B S T R A C TIntroduction: Although decision-making processes have become a principal target of study among addiction researchers, few researches are published according to effects of different treatment methods on the cognitive processes underlying decision making up to now. Utilizing cognitive modeling method, in this paper we examine the effects of Methadone maintenance treatment (MMT) on ...
In this paper, the authors have focused on the stochastic analysis of an internet data center (IDC), which consists of a database main server connected to a redundant server. Observing the different possibilities of functioning of the system, analysis has been done to evaluate the various reliability characteristics of the system. The system can completely fail due to failure of redundant serve...
This paper aims to propose a modeling framework for subway operation and maintenance system (SOMS), which analyzes the train condition data based on both train sensor network data and basis train maintenance plan. The system is formulated into five function modules, and the research problem is to determine one auxiliary maintains plan, including the time allocation and frequency of maintenance....
In this paper, a comprehensive mathematical model for designing an electric power supply chain network via considering preventive maintenance under risk of network failures is proposed. The risk of capacity disruption of the distribution network is handled via using a two-stage stochastic programming as a framework for modeling the optimization problem. An applied method of planning for the net...
Objective: The present study aimed at the structural modeling of family function and drug craving in addicted people under methadone maintenance treatment with the emphasis on the mediator role of self-compassion. Method: This research is a correlational study in which path analysis method has been used to examine structural connections between the variables. The statistical population of this...
The proliferation of Mobile P2P systems made a next generation mobile BitTorrent client an appropriate target to compare two different development approaches: the traditional manual coding and domain-specific modeling languages (DSMLs) accompanied by generators. We present two DSMLs for mobile communication modeling, and one for user interface development. We compare the approaches by developme...
In this article, the intricacies involved in the maintenance of the industrial repairable systems are analyzed. Based on the practical requirement, the mathematical models for repairable system maintenance which are using point process theory are listed and reviewed. The available estimation, inference and prediction methodologies are also listed. The future issues which are to be addressed in ...
Long lasting systems like airplanes have a cost structure where the maintenance costs are larger than the purchasing costs. Besides, the growing amount of electronics leads to a much higher sensitivity with respects of failures in the electronic system. Testing is required, both for preventive maintenance as well as repair. Previously we have looked at the impact of test and design for testabil...
We present the application of software process modeling and simulation using an agent-based approach to a real case study of software maintenance. The original process used PSP/TSP; it spent a large amount of time estimating in advance maintenance requests, and needed to be greatly improved. To this purpose, a Kanban system was successfully implemented, that demonstrated to be able to substanti...
A discontinuity exists between modeling and objectoriented programming languages. This discontinuity is a consequence of ambiguous notions in modeling languages and lack of corresponding notions in objectoriented programming languages. It hinders the transition between software implementation and design and hampers software maintenance. This discontinuity is particularly acute for binary class ...
