Software enhancements and the maintenance phase is generally the crucial phase of a software application lifecycle. The enhancements and maintenance consume about 20% of the overall software lifecycle effort. Enhancement and maintenance phase of modern digital projects involves many activities such as incident management, application enhancements, generic maintenance, quality improvements such as automation, preventive maintenance, continuous improvement, and such. State-of the-art estimation models and frameworks fall short of factoring all the dynamics involved in the enhancements and maintenance phase. The article proposes a digital project maintenance estimation framework to estimate various activities of a digital maintenance project. The proposed estimation framework provides comprehensive coverage of maintenance activities including incident management, application enhancements, generic maintenance, and quality improvements. The proposed estimation framework was used to predict effort estimate of 5 digital maintenance projects with MMRE of 0.255 and predicted (0.3) of 80%.

Production Target

Petlin (Malaysia) Sdn Bhd was incorporated in March 1999 and has a Low Density Polyethylene plant that was commissioned in February 2002. The plant has a capacity of 255,000 tons per annum. The aim of the plant is to generate a reasonable return by manufacturing top quality products. To realize this aim, it’s important for the operators of the plant to operate the machines in accordance to the parameters set by the original equipment manufacturer. This will also ensure the availability and reliability of the plant. It is also important to regularly monitor the performance of the plant in relation to the operation and maintenance activities in order to prepare a better plan for continuous improvement. The Hyper-Compressors are the most fragile component in the system as they’re running under fatigue conditions and high operating pressures. It is essential to have the right processes and procedures in place to ensure that safety is not compromise in meeting the production target.

The purpose of this project is to design a knowledge management application as a media to document knowledge and facility that supported a knowledge sharing culture in Oracle Financial subdivision in Orang Tua Group. The researcher uses 7 first steps method which defined by Tiwana in doing knowledge management application prototype. The knowledge management prototype application modules consist of Wiki page, document library, discussion board, blog, picture library, knowledge base, help desk, frequently asked questions, and surveys. In using knowledge in knowledge base, user will get knowledge through business process, how to use the application, or how to finish some cases. Knowledge management prototype application design as a whole could fulfill user’s needs in sharing knowledge, but still needs continuous improvement for maximal usage.Keywords: prototype design, knowledge management application, knowledge

Colorectal Cancer Patients

Prediction in health care is closely related with the decision-making process. On the one hand, accurate survivability prediction can help physicians decide between palliative care or other practice for a patient. On the other hand, the notion of remaining lifetime can be an incentive for patients to live a fuller and more fulfilling life. This work presents a pipeline for the development of survivability prediction models and a system that provides survivability predictions for years one to five after the treatment of patients with colon or rectal cancer. The functionalities of the system are made available through a tool that balances the number of necessary inputs and prediction performance. It is mobile-friendly and facilitates the access of health care professionals to an instrument capable of enriching their practice and improving outcomes. The performance of survivability models was compared with other existing works in the literature and found to be an improvement over the current state of the art. The underlying system is capable of recalculating its prediction models upon the addition of new data, continuously evolving as time passes.

The recent advancements in information and communication technology (ICT) have inspired all the operational domains of both public and private sector enterprise to endorse this technology. Software development plays a crucial role in supporting ICT. Software effort estimation serves as a critical factor in software application development, and it helps application development teams to complete the development process on time and within budget. Many developmental approaches have been used for software effort estimation, but most of them were conventional software methods and therefore failed to produce accurate results when it came to web or mobile effort estimation. This chapter explains different types of software applications, software estimation models, the importance of software effort estimation, and challenges faced in software effort estimation.

Ship Repair

The costs in shipbuilding and ship repair and maintenance activities are massive and need several materials in the same production phase. Construction without planning is not rational, and any mistake in the planning phase will cause major loss of time, quality, and financial resources. Planning in ship repair and maintenance yards is more complicated than new building shipyards because the duration time is limited. In this study, 200-m-long tanker’s repair and maintenance period has been planned by program evaluation and review technique analysis in light of the data acquired from X shipyard in Turkey to reflect critical activities that affect the total duration time.

One of the main goals of the Software Engineering discipline is to find higher abstraction levels and ways to reuse software in order to increase its productivity and quality. Ontologies, which are typically considered as a technique or an artifact used in one or more software lifecycle phases, may be used to help achieve that goal. This paper provides a systematic literature review of the proposed solutions for applying ontologies in automatic and generative programming. The paper aims to identify ontologies and software development tools, frameworks, prototypes, design patterns and methodologies that use them as development artifacts for source code generation or product derivation. The review provides researchers with the state of the art, while also identifying challenges and gaps that require further exploration and development.
