Year: 2022

Software engineering ethics has been an interest of the software engineering community for over two decades, as evidenced by the creation of the joint ACM/IEEE-CS Soft-ware Engineering Code of Ethics. When reviewing the cur-rent software engineering literature, it was found that Stack Exchange question-and-answer (Q&A) websites are particularly good means of gaining a better understanding on a given subject: what topics are addressed within a subject area, the popularity of these topics, and the difficulty of these topics. As such, this paper utilizes Stack Exchange Q&A websites to review software engineering ethics and presents a case study that aims to provide a better understanding of the presence of software engineering ethics on three popular Stack Exchange Q&A websites, which are Stack Overflow (SO), Software Engineering (SE), and Project Management (PM). The study analyzes over 2,170 posts, using Latent Dirichlet Allocation (LDA), to better understand what ethic-related topics are discussed. Subsequently, the authors analyzed the popularity and difficulty of each identified topic. The study found that users discuss six ethic-related topics, which are as follows: web scraping, software quality, software security, open-source software usage, team and employers, and software billing. Moreover, the results revealed that software security is the most popular and the most difficult topic. This study highlights ethic-related challenges that are faced by Q&A website users. Software practitioners, researchers, and educators can utilize the results presented in this study to pursue new avenues when addressing pressing issues related to software engineering ethics.

Scheduling tasks under resource constraints is essential for project success, and this research focuses on scheduling tasks efficiently to minimize completion time. To tackle this problem, two optimization techniques are employed: Linear programming (LP) and particle swarm optimization (PSO). PSO significantly reduces the duration, leading to a reduction in project duration. But the LP algorithm does not improve the project duration. Using suitable algorithms to maximize project efficiency and success is essential for successful project management. This research provides valuable information for project managers and decision makers, highlighting the importance of utilizing suitable algorithms to maximize project efficiency and success.
ESSE: an early software size estimation method based on auto-extracted requirements features
Authors: Cheng Zhang; Shensi Tong; Wenkai Mo; Yang Zhou; Yong Xia; Beijun Shen
Year: 2016

Software size estimation is a crucial step in project management. According to the Standish Chaos Report, 65% of software projects are over budget or deadline; therefore, a good size estimation method is very important. However, existing estimation methods are complicated and human-effort consuming. In many industrial projects, project technical leads (PTLs) do not use these methods but just give a rough estimation based on their experience. To decrease human effort, we propose an early software size estimation (ESSE) method, which can extract semantic features from natural language requirements automatically, and build size estimation models for project. Firstly, ESSE makes a two-level semantic analysis of requirements specification documents by information extraction and activation spreading. Then, complexity-related features are extracted from the results of semantic analysis. Finally, a size estimation model is trained to predict size of new projects by regression algorithms. Experiments in real industrial datasets show that our method is effective and can be applied to real industrial projects.

Implementing BIM for conventional tunnels - a proposed methodology and case study
Authors: A. Mitelman; Ury Gurevich
Year: 2021

The topic of Building Information Modelling (BIM) adoption by public organizations has become a central subject of research, and a significant amount of BIM documents, guidelines, and standards have been created to meet different organizational purposes. Compared to the building industry, the application of BIM tools for tunnel project management is lagging far behind. This paper proposes a methodology for integrating BIM tools for conventional tunnelling. A fundamental distinction is made between the tunnel internal architectural domain and the external structural domain. For the former, BIM methodology can be applied similarly to the building industry. For the latter, it is suggested that a BIM model be built according to the essential information generated during tunnelling excavation. The proposed methodology was put to test for an actual tunneling project. A routine was established where the supervisor on behalf of the owner was responsible for gathering and reporting essential data in tabular form. Via REVIT's Application Programming Interface (API), a code was developed so that a BIM model was built and updated automatic to data insertion. Ultimately, the final BIM model allows managing up-to-date qualitative and quantitative information visually. Thus, human understanding and interpretation are enhanced for future uses, such as maintenance, future renovations and project post-analysis.

A novel swarm intelligence approach for the constrained scheduling problem
Authors: Bidisha Roy; Asim Kumar Sen
Year: 2023

ABSTRACT The Resource Constrained Project Scheduling Problem (RCPSP) is a prevalent problem in the domains of Project Management and Operations Research. This problem demands a huge number of computational resources as the project’s complexity increases. Hence, approximate methods using heuristics and metaheuristics have proven to provide feasible solutions to the problem in acceptable time. This research adapts a prominent Swarm Intelligence (SI) metaheuristic, the Firefly Algorithm (FA), to solve the RCPSP with some modifications. By applying a 2-point crossover for the intensity-based firefly movement, a discrete framework has been provided. Further, to reduce the occurrence of the solution being stuck in the local optima, a swap-based mutation is introduced. The performance of the proposed research has been thoroughly evaluated through extensive experiments conducted on widely recognized benchmark instances. Comparison with seminal works demonstrated the competitiveness of the approach.
Improving estimation accuracy of the COCOMO II using an adaptive fuzzy logic model
Authors: I. Attarzadeh; S. H. Ow
Year: 2011

Software development time and cost estimation are the process of estimating the most realistic use of time and cost required for developing a software. It is one of the biggest challenges in the area of software engineering and project management, in the last decades. The software estimates are difficult to obtain due to incomplete software information is available in the early phase of software development process. Insufficient software information causes inaccuracy in software attributes. Thus, the vagueness and uncertainty of the software attributes is the main reason of inaccuracy of software estimates. Software cost estimation models such as regression model, expert judgment, SLIM, and COCOMO require accurate software attributes and long term estimation process, which are not completely achievable in early phase of software development process. Soft computing techniques such as fuzzy logic can reduce the vagueness and uncertainty of software attributes. Therefore, it may consider as alternative to decrease the inaccuracy of software estimates. This research aims to utilise an adaptive fuzzy logic model to improve the accuracy of software time and cost estimation. Using advantages of fuzzy set and fuzzy logic can produce accurate software attributes which result in precise software estimates. The Two-Dimension Gaussian Membership Function (2-D GMF) was used in the fuzzy model to make software attributes smoother in terms of the range of values. The COCOMO I, NASA98 data sets; and four project data from a software company in Malaysia were used in the evaluation of the proposed Fuzzy Logic COCOMO II (FL-COCOMO II). The evaluation of the obtained results, using Mean of Magnitude of Relative Error (MMRE) and PRED(25%) evaluation techniques, showed that the FL-COCOMO II produced the MMRE less than the original COCOMO and the value of PRED(25%) in the Fuzzy-COCOMO II is higher than the original COCOMO. Furthermore, the FL-COCOMO II showed 8.03% improvement in terms of estimation accuracy using MMRE when compared with the original COCOMO. Using advantages of fuzzy logic such as accurate estimation; adaption; understandability, and etc., can improve the accuracy of software estimates.
The parametric modeling and management system for boiler steel frame
Authors: Jing Chen; Shijing Wu; Xuemei Tang
Year: 2012

With the development of society, the structural steelwork tends to be larger in scale and more complicated in system. The increasing difficulties in construction ask for higher efficiency and security. Traditional 2D drawings can hardly satisfy the requirement of structural instructions, for example, the construction of boiler steel frame. This article focuses on the imperfections of 2D drawings in expressing 3D images. In order to reduce the pressures of reading drawings and dimensional analysis on engineering staffs, the use of CATIA to build 3D models by 2D drawings with the given information is suggested. Meanwhile, according to statistical methods of project management, a system managing engineering part is designed. Through the application of 3D modeling, the overall situation of the engineering structure can be known, and parts lofting and erection outfitting can be avoided. The statistical management over elements is also realized. The research focuses on the case of the boiler steel-frame owned by a thermal power plant in Hubei. 3D model is constructed by using information of 2D drawings to calculate the required mechanical equipment, human recourse and materials concerned with the project. It managed to shorten the project preparation time by one month, reduce the construction difficulties and ensure that the requirements on equipment, human recourse and materials are all satisfied.
Top Ten Behavioral Biases in Project Management: An Overview
Authors: B. Flyvbjerg
Year: 2021

Behavioral science has witnessed an explosion in the number of biases identified by behavioral scientists, to more than 200 at present. This article identifies the 10 most important behavioral biases for project management. First, we argue it is a mistake to equate behavioral bias with cognitive bias, as is common. Cognitive bias is half the story; political bias the other half. Second, we list the top 10 behavioral biases in project management: (1) strategic misrepresentation, (2) optimism bias, (3) uniqueness bias, (4) the planning fallacy, (5) overconfidence bias, (6) hindsight bias, (7) availability bias, (8) the base rate fallacy, (9) anchoring, and (10) escalation of commitment. Each bias is defined, and its impacts on project management are explained, with examples. Third, base rate neglect is identified as a primary reason that projects underperform. This is supported by presentation of the most comprehensive set of base rates that exist in project management scholarship, from 2,062 projects. Finally, recent findings of power law outcomes in project performance are identified as a possible first stage in discovering a general theory of project management, with more fundamental and more scientific explanations of project outcomes than found in conventional theory.
