for better understanding of tehran ground water, samples were taken randomly from 340 out of 655 deep & semi deep wells in 1993, which dug by tehran water supply and sewage engineering company. 260 water specimens were examined chemically and physically and compared with the 1993 world health organization (who) and food and agriculture organization (fao) criteria and analyzed statistically. log...

Software engineering is the discipline which paves the road map for the development of software within the given schedule and effort with the desired quality. The process begins with estimating the size, effort and time required for the development of the software and ends with the product. In most existing research on the effort estimation, the Function Point Analysis (FPA) method is used to e...

The last decade marked the first real attempt to turn software development into engineering through the concepts of ComponentBased Software Development (CBSD) and Commercial Off-The-Shelf (COTS) components, with the goal of creating high-quality parts that could be joined together to form a functioning system. One of the most critical processes in CBSD is the selection of a set of software comp...

Software reliability deals with behaviour of a software system in operation and it is defined as the probability of working without failure for a specified interval of time. In a number of recent disasters the computer has been wholly or partially to blame. In Ref. [1] an alarm signal is given by the following message: "Sometime soon, software reliability is going to become a highly visible and...

the present article discusses and presents a new and comprehensive approachaimed at measuring the maturity and quality of software processes. this method has beendesigned on the basis of the software capability maturity model (sw-cmm) and themulti-level fuzzy inference model and is used as a measurement and analysis tool. among themost important characteristics of this method one can mention si...

quently requested by software clients, Many clients seek products that maintain themselves or can be maintained by a third party. This model required considerable effort to develop, eventually resulting in a set of quality properties that are measurable from the source code and related to the subcharacteristics of quality proposed in ISO/IEC25010 (Table 1). • The Evaluation Environment which la...

Program quality represents the most significant part of software quality control that assures all characteristics of software products to satisfy the user’s explicit and implicit needs. Though software processes have to be improve to enhance software quality. In this paper we address the problems of software products at the source code level, and deal with those problems by using a coding stand...

This study proposes quality measurement attributes for Application Service Quality Indicator (ASQI) to measure the quality of application software in the operation stage using the KJ technique and by reviewing some existing methodologies, such as ISO 25000 quality standard, BSC, EA PRM, SERVQUAL, and SLA. As during operational stages software quality is defined variedly in terms of software, ma...

In last decade, software engineering research increasingly focused on software quality enhancement and evaluation, whereas most of these researches concentrate on the internal/ development perspective. However, users mainly care in the quality of performs intended functions efficiently without knowing how the software product was developed, how it is work from inside, or it is internal quality....

The availability of networked software services is an increasingly important quality of service issue. A service user gauges service availability in terms of initial access time and subsequent service delivery time. This paper develops – from a user perspective – a quality of service framework for the availability of networked software services. The paper utilises this quality of service framew...
