  • Forecasting of traffic flows at ferry terminals. A hybrid model   Order a copy of this article
    by Iñigo L. Ansorena 
    Abstract: This paper presents an agile approach for managing ferry terminals. We propose a double-stage model that forecasts traffic. The hybrid model is based on quantitative tools. First we search for associations in data and then we develop a time series analysis. The specific objectives of the study are firstly to survey and collect data at a disaggregated level in terms of passenger and vehicle flows, and time periods; and secondly to develop forecasts on short term using a combination of the proposed techniques. We think that the simultaneous application of historical analogy and time series forecasting is a powerful tool to predict the future traffic. Additionally, the methodological procedure proposed in this paper is general enough to be applied to other traffics and ports.

  • Effect of Enterprise Social Media and Psychological Safety on Employees Agility: Mediating Role of Communication Quality   Order a copy of this article
    by Abdul Hameed Pitafi, Shamsa Kanwal 
    Abstract: Enterprise social media (ESM) is an open and public platform that facilitates employee discussions on work-related issues. However, researchers and practitioners are vague about the advantages of ESM usage in the workplace to handle the work related uncertainties. This study investigated whether and how ESM usage, psychological safety can be positively associated with employees agility. Employees agility is the ability of the employee to react and adopt environmental changes more promptly and appropriately. Based on information processing theory, this study examines employee agility by considering the mediating effect of communication quality. Data was collected from 167 employees who adopted ESM in the workplace, the existing study supports our proposed hypotheses and mediating effect. The findings confirm the significant role of ESM usage and psychological safety in improving employee agility through communication quality. This research study contributes to the existing ESM literature by investigating communication quality and its role in developing employees agility in the context of ESM and suggesting managerial implications of ESM usage in improving the employees agility.
    Keywords: Enterprise Social Media; Employee’s Agility; Psychological Safety.

  • Effect of machining parameters over surface roughness in contour milling of Aluminium 2024-T351 using 5-axis Parallel kinematic Machine   Order a copy of this article
    by Suryam LV 
    Abstract: Surface roughness is reduced by optimizing the machining parameters. This research analyzes the effect of machining parameters on surface quality of Aluminum 2024 T351 in milling of semi-circular pocket with carbide tool on 5-axis Hybrid Parallel Kinematic Machine (HPKM). Three different segmented surfaces were selected on semi-circular pocket and investigated the influence of machining parameters. The selected parameters are spindle speed, feed rate and depth of cut. Investigation of this study results in the optimum parameters that could produce good surface finish. The effect of these cutting parameters is evaluated using L9 Taguchi orthogonal array, s/n ratio, analysis of variance (ANOVA). Based on the result analysis, good surface finish can be obtained at high cutting speed, low feed rate, and low depth of cut. Also, the maximum influence of feed rate among the selected surface segments was ascertained.
    Keywords: 5-axis PKM; Contour milling; Surface roughness; Taguchi method; s/n ratio;.

  • A multipath methodology to promote ergonomics, safety and efficiency in agile factories   Order a copy of this article
    by Silvia Ceccacci, Marco Matteucci, Margherita Peruzzini, Maura Mengoni 
    Abstract: An important area of risk management practice for manufacturing companies relates to the prevention of injuries and musculoskeletal disorders (MSDs). The greater benefits can be achieved where a preventive approach is used, based on ergonomic design of workplaces and attention to human requirements and limitations as well as human-machine interaction principles. The research aims at providing a pragmatic approach to support the application of ergonomic risk management in practice. It defines a multipath methodology to investigate human factors impacting on safety by considering the specific workspace, the adopted tools, the overall production environment and the workers activity. An industrial case study is described to illustrate the methodology and demonstrate the benefits for companies. Results suggest that the proposed multipath methodology allow to effectively assist analysts in the definitin of crucial risk factors and selection of proper ergonomics assessment and measurement tools accordign to the specific context of application.

  • A comparative analysis of factor analysis Model for Pinpointing Agile Developers   Order a copy of this article
    by Alok Khatri, Dixit Garg, G.S. Dangayach 
    Abstract: Agile manufacturing is an emerging approach of engineering to deal with dynamic demand of customer and market. The Prime factors that influence agility are agile developers and enablers. Agile developers are mainly less investment factors that are basically governed by managerial power. To find out most important agile developers, a survey based study was conducted with the aim to develop model for agility developers and measure its level in Indian manufacturing industries. It was hypotheses that sensitiveness to change, relationship with customer, relationship with supplier, flexibility and competency and responsiveness is not significant with agile manufacturing. The data were analyzed by ANNOVA test, different factor analysis techniques and a complete regression model for agile developer was prepared with the help of Analytic hierarchy process. It was found that design excellence and decision flexibility variables have highest importance among all components and developers are being used almost at their 50% level.
    Keywords: Agile manufacturing; agility developer; principal component analysis; linear regression model; Artificial neural network (ANN); Analytic hierarchy process (AHP).

  • Modelling the Factors of Agility of Humanitarian Operations   Order a copy of this article
    by Suresh M, Ganesh S, Raghu Raman 
    Abstract: The commercial concept of agility, when responding to humanitarian operations, has strong potential for increasing efficiency and effectiveness. The aim of this paper is to explore the concept of agility in the context of humanitarian operations, particularly cart festivals in India. This responds to the increasing pressure on festival organizers and public administrative officials to manage the festival and to control the crowd and other supporting facilities in a particular time window. Agility plays a major role in accommodating the unpredicted changes in cart festivals. Attempts are made to identify the factors which influence the agility of humanitarian operations. In this study, Interpretive Structural Modelling (ISM) approach is applied to find the interrelationships among the factors. Finally, it is found that the most influential factors are multi-skilled and flexible people, Informal learning and development, completeness and change of culture.
    Keywords: Humanitarian Operations; Agility; Change Management; Event Flexibility; Interpretive Structural Modelling.
