The emotional stress and uncertainties associated with foreign exchange (forex) trading due to the high risk of losing the investment capital has left most forex traders in a state of indecision on the best methodology to apply for achieving long term profit. The provision of lot sizes, leverages, take profits and stop losses in forex trading implies that very high profit can be made within a very short time with the same capital, but at the same time, very high losses can be incurred. On one hand, this provision often prompts a set of traders to become greedy by increasing their take profit levels, lot sizes and leverages, which in turn increases their probability of losing out. On the other hand, the provision creates doubts and induces the fear of losses in some other set of traders. Consequently, these set of conservative traders employ the use of relatively small lot sizes, low leverages and low values of take profit and high stop loss levels. This in turn often results in a devastating effect on the investment capital due to lost opportunities and resulting losses. The problem of losses in forex trading effort is compounded by the fact that many programmers and developers of forex expert advisors do not adopt a software life cycle, having learned only how to write codes to program the trading platform. Furthermore, software engineering professionals who understand the import of software development life cycles soon discover that conventional software life cycles are not capable of effectively handling the complexity of the forex market. This paper models the human characteristics of greed, fear and doubt as manifested by traders in forex trading using selected expert advisors’ properties. It proposes Facts, Analysis, Implementation, Testing and Hope (FAITH) software life cycle model for Forex trading profitability to tackle the problem of indecision in the development of forex expert advisors. The proposed model was implemented on a live trading platform for a period of three months and compared with doubt, fear and greed approach to trading. The results showed that while a level of greed can be profitable, FAITH software life cycle produced more profitable results and can be adopted for forex trading.

The Web

Today, the Internet and the Web are the most amazingly and dynamically growing computer technologies. The number of users accessing the Web is growing exponentially all over the world. The Web has become a popular environment for new generation of interactive computer applications called Web (or hypermedia) application. The Web applications (WAs) have special characteristics that have made them different from other traditional applications. Hence, many design methodologies for the development of WAs have been proposed. However, most of these methodologies concentrate on the design aspects of applications, and they often do not strictly follow any software development life-cycle model such as the WaterFall software development life-cycle model. In this chapter, we propose an object-oriented design methodology for the development of WAs. The main features of this proposed methodology are that it follows WaterFall model and captures the operations in objects of the applications; thus making the methodology an object-oriented methodology.

Purpose – This study aims to propose a hotel life cycle model and applies this model to examine the development of international tourist hotels (ITHs) in Taipei. Design/methodology/approach – In this study, a two-stage approach is proposed to examine the life cycles of 20 ITHs in Taipei. First, we evaluate the overall and departmental efficiencies by using a two-layer bootstrap data envelopment analysis (DEA) model. Second, we divide the phases of the hotel life cycle by incorporating two objective indicators, namely, the average efficiency change rate (AECR) and the annual average efficiency (AE). Findings – The results show not only that the efficiency scores derived from the bootstrap DEA model could help assess the performance of individual ITHs but also that the resulting AECR and AE could help to objectively classify the development of the hotels under study into the following phases: initial, growth, maturity and recession and regeneration phases. Practical implications – The method proposed in, and the results obtained from, this study can provide the stakeholders of the ITHs in Taipei with an alternative to the existing subjective enterprise life cycle (ELC) model for identifying these ITHs’ stages of development using quantitative and objective criteria. Originality/value – Existing hotel management research rarely focuses on hotel life cycle analysis, likely due to the adoption of subjective criteria by the conventional ELC model, which limits the practical application of the research. To improve on the conventional ELC model, our proposed quantitative approach involves dividing the hotel life cycle by employing two objective indicators and then empirically presenting the results.

The ten-year gap between the emergence of Software Engineering (SE) and Knowledge Engineering (KE) has led to the two disciplines developing along different methodological lines. In this paper, we point out that, after having passed through a period during which they ignored each other, followed by a competitive phase, the two disciplines have now reached a meeting point. We see the need for a life-cycle model for systems that integrate traditional and knowledge-based software. Besides, software development in the 21st century will entail open requirements and technological tools that will evolve during the life-cycle. Finally, the paper discusses a proposal for a conical-type spiral life-cycle model that seeks to meet all those needs.

Pangsa pasar yang semakin berkembang di berbagai bidang usaha khususnya pada jasa, membuat sistem pembukuan penjualan yang belum menggunakan komputer menjadi tidak efektif. Salah satu contoh bidang usaha tersebut adalah usaha rental mobil. Proses pengolahan data transaksi perusahaan tersebut semakin tidak akurat dan lambat seiring dengan meningkatnya transaksi yang dilakukan. Atas dasar tersebut digunakan Sistem Informasi Rental Mobil yang berbasis komputer sehingga lebih cepat dan akurat. Sistem Informasi tersebut dibuat dengan menggunakan bahasa pemrograman Java dan menggunakan database MySQL yang tertanam langsung pada aplikasi. Proses pembuatan dan pengembangan Sistem Informasi Rental Mobil ini menggunakan metode SDLC (Software Development Life Cycle) model air terjun. Hasil dari perancangan aplikasi ini adalah suatu aplikasi desktop yang dapat memudahkan pengguna dalam pencarian mobil yang sedang tersedia, penagihan pembayaran dan pengembalian mobil jika batas waktu pengembalian sudah tiba.
