Development of a Morphological Box to Describe Worker Assistance Systems in Manufacturing

This paper focuses on the complex selection process of worker assistance systems for human-centered manufacturing systems. Due to rising complexity of products and processes in the manufacturing sector, as well as changing work environments, the choice for suitable support systems on the shop floor becomes more difficult. The selection of worker assistance systems is yet not well studied and there is a lack in scientifically based methodologies to assist designers of manufacturing systems in this process. In this work we identify a broad variety of influencing attributes for selecting the most appropriate worker assistance systems depending on each individual field of application. These attributes are building the ground for the development of a morphological box to facilitate the selection process of worker assistance systems. The proposed procedure to use the morphological box is finally explained with a practical example.

Evaluation of the selection of proper metro and tram vehicle for urban transportation by using a novel integrated MCDM approach.

This paper presents a novel integrated multi-criteria decision-making model consists of the CRITIC (CRiteria Importance Through Intercriteria Correlation) technique and the EDAS (The Evaluation based on Distance from Average Solution) method to evaluate the selection of the urban rail vehicles operated in the public transport systems. In order to determine the selection criteria in a more realistic perspective, a board of experts consists of seven members, who perform as senior executives in the public transport institutions of the country, was constructed and many round tables meetings were organized with together the members of the board for determining the procedure to follow to reach meaningful and applicable results. At the beginning of the research, approximately fifty selection criteria were determined by the research team and some of them were eliminated during the preparation process of this study. Finally, 22 factors were determined as the selection criteria, which will be used in this research. These factors are the selection criteria directly or indirectly affecting the selection process and results. Also, rail tram types currently operated in the various cities of Turkey were determined as decision alternatives. These options were evaluated by using the proposed integrated MCDM approach. When the obtained results are evaluated, it can be seen that the proposed model has the potential to give very successful results for evaluating the selection process of the urban rail systems. Moreover, it can be implemented as a decision support system by decision-makers, who perform in the public transport authorities. Finally, it can also be applied for decision-making problems faced in the various fields.

A novel framework for optimal photovoltaic size and location in remote areas using a hybrid method: A case study of eastern Iran

Photovoltaic (PV) energy generation is one of the more promising renewable energy technologies. However, determining optimal specifications (e.g., size, location) for PV systems is a significant challenge for planners and investigators of distribution systems. In this paper, a framework is provided for integrating geographical information systems, artificial bee swarm optimization, and simulation to determine the optimal size and location for PV panels on an annual basis. A geographical information system module is developed first to determine the suitable location and capacity for a stand-alone PV system in rural areas, taking into account the technical, environmental and socio-economic criteria affecting the site selection process of stand-alone PV systems. Then an efficient heuristic approach, namely artificial bee swarm optimization, is proposed for optimum sizing of a stand-alone PV system to continuously satisfy the load demand with minimal cost and enhanced energy system reliability. For this aim, the maximum allowable loss of power supply probability is also considered. The proposed framework is applied to a real case study in eastern Iran and the results show that it can effectively be used for off-grid photovoltaic projects in rural areas considering both power quality and cost.

Hurdles in selection process of nanodelivery systems for multidrug-resistant cancer.

Most of the nanomedicines for treatment of multidrug-resistant cancer do not reach Phase III trials and many are terminated or withdrawn or are in an indeterminate state since long without any study results being presented. Extensive perusal of nanomedicine development research revealed that one of the critical aspects influencing clinical outcomes and which requires diligent scrutiny is selection process of nanodelivery system. Research papers and articles published on development of nanodelivery systems for treatment of multidrug-resistant cancer were analyzed. Observations and conclusions noted by these researchers which might shed some light on poor clinical performance of nanocarriers were collated and summarized under observation section. Further research articles were studied to find possible solutions which may be applied to these particular problems for resolving them. The inferences of these findings were composed in Result section. Plausible solutions for the observed obstacles were noted as examples of novel formulations that can yield the following: better in vivo imaging, precise targeting and dosing of a specific site and specific cell type in a particular cancer, modulation of tumor surroundings, intonation of systemic effects and high reproducibility. The angle of approach to the development of best nanosystem for a specific type of tumor needs to be spun around. Some of these changes can be brought about by individual scientists, some need to be established by collated efforts of scientists globally and some await advent of better technologies. Regardless of the stratagem, it can be said decisively that the schematics of development phase need rethinking.

Integrating building information modeling (BIM) and LEED system at the conceptual design stage of sustainable buildings

Designing environmentally friendly buildings that provide both high performance and cost savings is of increasing interest in the development of sustainable cities. Today, we are looking at not just buildings’ certification but sustainable practices that go beyond ratings to satisfy our social responsibilities. The construction industry in general will benefit from an integrated tool that will help optimize the selection process of materials, equipments, and systems at every stage of a proposed building's life. Building information modeling (BIM) has the potential to aid designers to select the right type of materials during the early design stage and to make vital decisions that have great impacts on the life cycle of sustainable buildings.This paper describes a methodology that integrates BIM with the Canadian green building certification system (LEED©). Also, it explains how this integration would assist project teams in making sustainability related decisions while accumulating the required number of points based on the applied green building rating system. The methodology depicts the implementation of a model that automatically calculates the compiled number of LEED certification points and related registration costs for green and certified materials used in designing sustainable buildings all within the concepts of BIM. Using BIM in this methodology will help designers to invent and animate sustainable buildings in 3D mode easily and efficiently at the conceptual stage. The design information of the proposed sustainable building will be produced in a timely manner by using new plug-ins, which are developed for that reason, and which will link the BIM model with an external database that stores sustainable materials and assembly groups. A real case project is presented to illustrate the usefulness and capabilities of the proposed model.

ASSESSING DISCREPANCIES IN CURRENT PRACTICES FOR SELECTING HEATING, VENTILATING AND AIRCONDITIONING SYSTEMS IN BUILDINGS

The selection process of heating, ventilating and air conditioning (HVAC) systems is a crucialprocess that irritates decision makers. In Egypt the selection process of such systems is mostlybiased by the perception of the owner, his intuition and the pre- set budget by the manager. Thenon- objective decision making and the inappropriate selection of (HVAC) systems cause severeproblems that range from changes in the space requirements to adapt with the chosen system, theprovision of accessibility for maintenance and finally affecting their cost effectiveness. Both thearchitect and the electromechanical team are the primary stakeholders concerned with the actualselection process of the HVAC system. The divergence between their views is obvious in themethods and priorities of their selection process. Thus managing good understanding between thearchitect and the electromechanical team is crucial. This study intends to access the currentpractices used in the selection process of HVAC systems in buildings, through showingdiscrepancies among both perceptions; the architect's and the electromechanical. To achievethe objective of the paper a questionnaire was conducted. The target groups included students,graduates and experts in architecture and electromechanical disciplines. The results of this studyshowed remarkably how differences between the selection processes conducted by the target groupshad a great impact on the efficiency of selected HVAC systems in buildings

CONFIGURAÇÃO DE UM PROCESSO DE SELEÇÃO, AQUISIÇÃO E IMPLEMENTAÇÃO DE ERP CONSIDERANDO OS GRUPOS SOCIAIS ENVOLVIDOS

The life cycle of ERP extended the phases of the life cycle of systems, as stated by the Systems Theory. After ERP systems were introduced in the market under the conception of “packaged products”, phases like selection and acquisition started to compose their life cycle. Since then, a larger group of stakeholders - such as software suppliers, consultants and governmental entities or partners - becomes involved in the process, looking for an ERP system that could assure efficiency, transparency, integrity and trustworthiness of the information, in order to get better performance in decision making. This paper aims to configure the selection, acquisition and implementation process of an ERP system, considering the social groups involved in each phase of this process. Through the application of grounded theory methodology (chronological arrangement, codification of categories and a continuous theoretical saturation) it was possible to configure the process of selection, acquisition and implementation of ERP systems in two case studies. These case studies allowed the emergence of organizational context elements (strategy, culture, and environment), structuring elements (phases and steps) and enabling elements of the process which arose from the social-technical lens of the involved stakeholders. The main academic contribution relies in the use of grounded theory for the composition of the selection, acquisition and implementation process of ERP systems in a systematical way. Empirically, this study contributes by highlighting the trustworthiness and transparency of the process as a whole, assuring the choice, a greater adherence of the product to business requirements and a better use of the resources.

Information retrieval with geographical references. Relevant documents filtering vs. query expansion

This is a thorough analysis of two techniques applied to Geographic Information Retrieval (GIR). Previous studies have researched the application of query expansion to improve the selection process of information retrieval systems. This paper emphasizes the effectiveness of the filtering of relevant documents applied to a GIR system, instead of query expansion. Based on the CLEF (Cross Language Evaluation Forum) framework available, several experiments have been run. Some based on query expansion, some on the filtering of relevant documents. The results show that filtering works better in a GIR environment, because relevant documents are not reordered in the final list.

The Enterprise Resource Planning (ERP) selection process: case analysis and proposed framework

This paper presents several case studies of Enterprise Resource Planning (ERP) software selection and determines different factors and criteria that influence the decision of choosing an ERP solution. It also provides an analysis of the critical success factors for a successful implementation in order to demonstrate their dependence upon the selection process criteria. The study is concluded with a proposed framework for the standard selection process of ERP systems. The study is important as it attempts to streamline one of the most important decisions in the ERP implementation process and provides an alternative framework for the ERP systems selection process.

Ergonomic Evaluation of Winegrape Trellis Systems Pruning Operation

The winegrape industry suffers from high incidence rates of work-related musculoskeletal disorders. Pruning of dormant vines is a significant task, requiring long periods of highly repetitive and physically demanding work. The purpose of this study is to quantitatively evaluate five commonly used winegrape trellis systems with regard to the risk of developing musculoskeletal injuries to the wrist and lower back while pruning. Eleven subjects participated in this study. Subjects performed a simulated pruning task as wrist and trunk postures were gathered using electrogoniometers. The results showed significant postural differences among the trellis systems. Compared to the other systems, the VSP was determined to be the optimal system in terms of decreasing relative MSD risk. These results will assist vineyards in the selection process of suitable trellis systems that will include the worker health aspect in conjunction with other trellis-related parameters such as grape quality and productivity.
