These articles have been peer-reviewed and accepted for publication in IJSSE, but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

  • Systems Engineering and the Innovation Environment in US Defense Organizations   Order a copy of this article
    by Khaled Odeh, Rana Riad, Luis Rabelo 
    Abstract: Innovation may involve new designs and creations of products and services or improvement of existing products and services of an organization. A major element of measuring organizational strength is its innovation and ability to build on and sustain such strength. The environment of this research was comprised of the intersection of systems engineering within the context of US defense organizations. The goal was to determine the significant factors that could be used to determine innovation in projects within the specific environment using traditional statistics and data mining modeling techniques. One hundred and twelve (112) experts in the field of innovation and systems engineering from major defense organizations were interviewed and three hundred (300) projects were analyzed. Several factors were found that characterized the most innovative projects such as security and organizational leadership.
    Keywords: Systems Engineering; Innovation; Neural Networks; Classification Trees.

  • A Cause-Effect Strategy Map for Lean Process Transformation   Order a copy of this article
    by Waleed Mirdad, Chinweike Eseonu 
    Abstract: Lean process improvement has revolutionized complex global manufacturing, automotive, and healthcare systems, along with many others; however, there is a high rate of failure among organizations that attempt to implement lean. Research suggests poor lean implementation strategy and misunderstanding of lean are root causes of lean implementation failure. This study is focused on reducing the rate of lean implementation failure by identifying causal relationships that drive successful lean implementation. The Decision Making Trial Evaluation Laboratory method (DEMATEL) is used to determine cause effect relationships. Data is collected through a survey of lean practitioners, researchers, and a review of the lean literature. The resulting strategy map is a guide for principle-driven lean implementation.
    Keywords: Lean Manufacturing; Lean Strategy Map; Lean Performance Measures; Continuous Improvement.

  • Windowing Based Threshold Technique To Play The Simple Breakout Game At Neutral Attention level   Order a copy of this article
    by Gauttam Jangir, Rakesh Kumar 
    Abstract: Brain Computer Interface (BCI) applications focus on an assistive care and provide an alternative communication for the persons who are suffering from locked-in-syndrome disease. To return their autonomy BCIs gaming provides a way for entertainment. From device control, the following are the major categories of BCI i.e. user state monitoring, evaluation, education, cognitive improvement, gaming, entertainment, safety and security. In the proposed work; the famous breakout game implementation is done using neurosky mindwave headset, in which blocks movement is controlled using EEG brain signals. Concentrating on the direction will generate visual evoked potential (VEP) in brain that will be retrieved using EEG signals. This research work focuses on the windowing based threshold (WBT) development and evaluating the players attention to play at neutral level. The proposed WBT (Windowing Based Threshold) algorithm is a process of grouping stream data and applying operations on them. WBT algorithm results are compared with existing constant threshold based algorithms and low alpha channel activities are also monitored.
    Keywords: Brain computer interface; windowing based threshold; EEG; visual evoked potential.

  • Holistic Methodology for Stochastic Mission Utility Analysis   Order a copy of this article
    by JaMar Watson 
    Abstract: Preliminary design of a future mission has profound effects on its lifecycle; yet, mission engineering is a discipline without unanimous definition and implementation. Current mission design philosophies are inadequate due to disaggregated design methods, incomplete mission phasespaces, exclusion of constitutive relations, curtailed tradespace exploration, and unsubstantiated concept solutions. Presented is a new methodology for simultaneously developing, exploring, and assessing statistically validated concepts of prospective missions. Stochastic modeling and simulation, providing multivariate mission utility analysis with concurrently integrated tradespace exploration, risk assessment, and holistic design, facilitates the methodology.
    Keywords: Mission Engineering; Mission Utility Analysis; System-of-Systems Engineering; Mission Simulation; Mission Modeling; Mission Architecture; Analysis of Alternatives; Concept Development and Experimentation.

  • Investigation of design and coordination issues in outpatient chemotherapy clinics using an ontology-based conceptual model   Order a copy of this article
    by Mahmoud Heshmat 
    Abstract: Chemotherapy is one of the most common treatment options for cancer. However, the caring service design is complex. In this paper, we develop an ontological model to check the consistency in the design process for identifying potential conflicts and improving communication and coordination in Outpatient Chemotherapy Clinics (OCCs). Checking the design issues is based on the notion that ontology could be used to conceptualise and represent the coordination and communication barriers in the current design. The paper describes how potential inconsistency might be detected through a conceptual model to account for the context of OCCs using the enterprise engineering approach DEMO (Design and Engineering Methodology for Organisations), and re-engineering or modification of the inconsistencies can be accomplished. The implications of the developed model revealed guidelines for modelling an ontological representation and automatically identifying problems and conflicts in the design process of the corresponding system. The main contribution of this work is exploring and proposing a solution for the explored coordination and communication issues between actor roles, in particular between the patient appointments scheduling stage and the treatment planning stage. This observed hindrance reflects two decision makers with opposing objectives for the same patient, namely the oncologist and the appointment scheduler in the actual system. Our improving suggestion is to provide an information link between the treatment planner and the patient appointment scheduling transaction by which the two actors supply each other with information converging to one statement. This result could be input to a prospective coordination and communication platform.

  • A Decision Making Support System for Identification, Management and Assessment of Territorial Vulnerability   Order a copy of this article
    by Roger Enrique Guzmán Avendaño, Holman Bolívar, Raul Menendez, Edwin Duran 
    Abstract: This paper presents the model used to support a decision making tool for guiding interventions in a territory. After conducting a systematic review to identify multi-criterion decision models relevant to the case on hand, a system based on service-oriented architecture was implemented The developed application allowed to obtain the short-, medium- and longterm actions necessary to strengthen a region before a natural disaster. As input to the tool, we used the information that characterizes a territory, starting from indicators grouped by dimensions (environmental, urban-regional, political-institutional, economic-productive and sociocultural). The information processing generates an overall vulnerability index and, for each dimension, the system recommends the actions to take. Even though the decision making models based on multi-criteria analysis produced different results, their combination with a services oriented architecture was seen as the best strategy for developing the decision making support system.
    Keywords: Information System; Multicriteria Decision; Systems for Decision Making, Territorial Vulnerability.
