Empirical software engineering aims at making software engineering claims measurable, i.e., to analyze and understand phenomena in software engineering and to evaluate software engineering approaches and solutions. Due to the involvement of humans and the multitude of fields for which software is crucial, software engineering is considered hard to teach. Yet, empirical software engineering incr...

The development of electronic commerce systems is subject to different conditions than that of conventional software systems. This includes the introduction of new activities to the development process and the removal of others. An adapted process must cope with important idiosyncrasies of EC system development: EC systems typically have a high degree of interaction, which makes factors like er...

Constructing an accurate effort prediction model is a challenge in Software Engineering. This paper presents three Bayesian statistical software effort prediction models for database-oriented software systems, which are developed using a specific 4GL tool suite. The models consist of specification-based software size metrics and development team’s productivity metric. The models are constructed...

The complexity of federal acquisition is increasing. Our ability as humans to mentally assimilate new laws, regulations, policies, and procedures into the existing body of knowledge in the acquisition field has already been surpassed. This paper will explore an emerging technique, known as the Analytic Hierarchy Process (AHP), that promises to help acquisition managers make rational decisions i...

There is many software development methodologies exist that is used to control the process of developing a software system. No exact system was found which could help the software engineers for selection of best software development methodology. This paper present the framework of expert system combined with Likert scale. With the help of Likert scale we create a rule based model and assign som...

Introduction: Decentralized wastewater treatment facilities are an expensive approach for developing countries. Decentralized wastewater treatment plants (DWWTPs) are a flexible technology. They have low construction and operational costs. Site selection is the most significant stage in the implementation of a DWWTPS. Therefore, the present study aimed to perform a site selection among the prop...

REACTOR is an expert system under development at EG&G Idaho, Inc., that will assist operators in the diagnosis and treatment of nuclear reactor accidents. This paper covers the background of the nuclear industry and why expert system technology may prove valuable in the reactor control room. Some of the basic features of the REACTOR system are discussed, and future plans for validation and eval...
