by NAVEEN VIRMANI, Rajeev Saha, Rajeshwar Sahai
Abstract: Leagile manufacturing has emerged as an innovative strategy in the last two decades. In this paper, critical success factors (CSFs) affecting leagile manufacturing have been identified through literature review and discussion with industrialists and academics. Fuzzy DEMATEL (Decision Making Trial and Evaluation Laboratory) technique have been applied to divide the CSFs in to cause and effect categories. It has been found that critical success factors 1 (Collaborative relationship), 3 (Strategic Management), 5 (Customer and Market sensitiveness), 7 (Human resource management), 11 (flexible manufacturing system), 12 (knowledge and IT management), 14 (Availability of funds), 15 (Benchmarking) falls under cause group while critical success factors like 2 (Management support towards Implementation of policy), 4 (Training and development programs), 6 (Design and Engineering), 8 (Virtual Enterprises), 9 (Use of advance manufacturing technologies), 10 (Supply chain Management), 13 (Rapid Reconfiguration) falls under effect group. The research will help the managers to identify the key factors and work accordingly in proper directions to implement leagile system in their organizations. Leagile system results in increased profitability, better quality of products, better customer satisfaction, better sales, increased productivity, increased sales, reduced manufacturing lead time etc.

A Systemic Approach to Applying Asset Orchestration Theory.
by Hamdan Mansoor, Richard Weston, Rohana Abdullah, Steven King, Peter Jackson, Paul Foley
Abstract: The paper proposes and uses a reference model of asset orchestration which characterises common organising relationships observed between the resource-based view and the dynamic capabilities view of firms. This reference model helps to visualise and communicate alternative common decision-making contexts needed to sustain competitive responses in firms through their lifetime, and thereby through the lifetime of the products and the services they realise. Little present literature describes the practical application of emergent asset orchestration (AO) concepts. Hence the present authors use their reference model to capture actual AO data within two case study firms. The captured data shows how AO theory can be deployed to direct strategic decision making towards sustainable configuration and deployments of a firms resource portfolio. Essential characteristics of the new reference model and of how it can be applied are reported in this paper.

Application of Response Surface Methodology in Evaluating the Performance of Conventional, Wiper, Cryogenically Treated and Coated (TiN, TiAlN And TiCN) Carbide Inserts in Turning of AISI 52100 Steel
by Venkat Pradeep Allu, Lingaraju D, Ramakrishna S
Abstract: The performance of untreated/uncoated, wiper, deep cryogenically treated, and coated (TiN, TiAlN and TiCN) carbide inserts using response surface methodology in turning of AISI 52100 steel, was evaluated in this study. Type of insert, cutting speed, feed and depth of cut were the factors investigated. The response variables analyzed were tool flank wear and surface roughness. Basing on RSM central composite design, an experimental plan (L18 OA) was developed. The ANOVA results signify that the suggested mathematical models could adequately elucidate the performance indicators within the range. The generated regression equation reveals that the flank wear is mainly influenced by the type of insert followed by cutting speed. The surface roughness was majorly affected by the type of insert followed by feed rate. Machined surface topographies and tool flank wear mechanism were analyzed by examining the SEM micrographs. RSM multi-response optimization was executed so as to optimize the turning parameters.

Improving logistics performance for One Belt One Road: A conceptual framework for Supply Chain Risk Management in Chinese third party logistics providers
by Michael Wang, Ferry Jie, Ahmad Abareshi
Abstract: Chinese government recently launched one belt one road to reform and speed up the development of Chinese economic in the world. One Belt One Road (OBOR) strategy heavily relied on the traditional logistical trade routes including terrestrial and oceanic Silk Road. Logistics performance may play a vital role for implementing the One Belt One Road plan. Especially, third party logistics providers as supporting members to carry out value-adding supply chain activities in one belt one road. According to literature review, supply chain risk is an issue to obstruct the development of logistics performance. The purpose of this paper is to present a conceptual framework for managing supply chain risks and improving logistics performance under the OBOR initiative in Chinese third party logistics service providers. There are very few studies on risk management in the OBOR initiative. We focus on the innovation, customer response and flexibility in the third-party logistics providers. This would provide a guide for both academics and practitioners to manage supply chain risks and improve logistics performance and enlighten them to pay attention to supply chain risk management in the Chinese third party logistics sector. In addition, this contributes to the supply chain and logistics management in One Belt One Road literature.
Keywords: logistics performance; supply chain; risk management; China.
Forecasting of traffic flows at ferry terminals. A hybrid model
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
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
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.

Application of Reconfigurable Machine Tools in the Capacity Control of Job Shop Systems
by Ping Liu, Qiang Zhang, Jürgen Pannek
Abstract: In today's market, demand fluctuation is a big challenge for manufacturers. They have to respond quickly and flexibly to satisfy customers' demands to improve the competitiveness. Moreover, it renders the production systems complex and dynamical. In this paper, we use capacity adjustment to deal with the fluctuation in demand. We derive an extended mathematical model of a typical job shop manufacturing system by introducing Reconfigurable Machine Tools (RMTs) to analyze the impact of this new class of machine tools on the dynamic behavior of the system. To improve the ability of capacity adjustment, we include the operations of RMTs into the classical Proportional Integral Derivative (PID) controller. Simulation results of a four-workstation job shop system demonstrate the proposed method can adjust the capacity effectively and show the potential of RMTs in the context of Industry 4.0.

Heuristic and Fuzzy Scheduling Synergy with Knowledge Acquisition of Resource Selection System Development for Home Healthcare Service
by Thepparit Sinthamrongruk, Jirawit Yanchinda, Keshav Dahal
Abstract: Home healthcare service provides daily medical services at patients homes. The service aims to satisfy the patients requirements which must be done by one or more qualified staff visiting them in right time. This paper proposes a new framework integrating the heuristic search and fuzzy logic with knowledge acquisition to develop reliable and effective decision to match qualified staff to offer homecare services with the minimum cost and better preference consideration under feasible time-slots. The framework is designed based on the hierarchical approach which divides the staff selection system into two layers: high and low level. The high level is responsible for retrieving information, such as patients locations, service distance and operation cost as well as dealing with constraints such as patients requirement and working time-slots. This information is passed to the lower level which is employed with fuzzy logic to estimate a set of the level of staff selection before returning results back to the higher layer to create the service plan.
Our empirical study shows that the proposed framework has a potential to provide improved solutions with minimized operating cost and improved patients satisfaction. The case study for the experiment comprises of 40 medical tasks with 8 service routes and 8 carers under time-slot windows.

Towards the measurement of Enterprise Information Systems agility to support EIS improving projects
by Jannik Laval, Chantal Cherifi, Vincent Cheutet
Abstract: Enterprise information systems (EIS) are directly implied in the global performance of an organisation. Nevertheless, their potential rigidity in comparison with the required fast evolution of the supported organisation remains an important open research question. The proposed research work aims to define and evaluate the agility of an EIS, in order to assist both software engineers and business managers in EIS improvement projects. In particular, a framework is proposed to structure the different existing metrics on agility according to the improvements needs and the intrinsic characteristics of an information system.
Keywords: Agility; enterprise information system; metrics; improvement project.
ICT enabled collaborative e-health for Cleft Lip/Palate treatment
by Noppon Choosri
Abstract: Sophisticated medical treatment often requires a multidisciplinary approach and a number of follow ups. This can limit the opportunity of patients who live in the remote areas to access quality and proper treatment due to the fact that healthcare services in Thailand are relatively centralized. The study proposes a collaborative framework to empower local healthcare clusters to service patients in their area of residence more effectively to minimize patient referral to their hub hospital. Several common features and constraints are identified. The investigation is to develop a practical ICT solution based on a case study of Cleft-Lip/Palate treatment using a network in Northern Thailand. Initial implementation of this enterprising project is outlined in this paper. The current progress includes two applications that have been developed to address the high priority issues of collaborative networking. One is to support data sharing for medical teams and the other is to facilitate patients to access better medical services.
