Manufacturing Execution Systems: An Accelerated Enablement Protocol
by Arnesh Telukdarie
Abstract: Production facilities deliver value as subsets of larger corporate entities with a key enabler being systems, inclusive of Enterprise Resource Planning (ERP) and supplementary systems. The enterprise requires operational data for strategic and operational management. Interdependent, upstream and downstream units are also data dependent for optimal operations. The efficiency of top floor to shop floor communication and vice versa, is highly dependent upon the technological maturity of the middle layer or Manufacturing Execution Systems (MES). This research focuses on the development of an evaluation toolset for Manufacturing Execution Systems maturity, specifically determining a Business Units system maturity relative to best practice. The core purpose of this research is to deliver a toolset that expedites the evaluation of a current business specific system, relative to a best practice scenario providing key data to maximize business.
The methodology includes hierarchical segregation of the business together with focused, internationally referenced, questions facilitating system maturity evaluations. The Likert association methodology facilitates data gathering. The toolset development is approached on a tiered basis with a business process specific focus. Results analysis focus on current maturity, required maturity and gap emphasis.

A fuzzy imperfect quality inventory model with proportionate discount under learning effect
by Rojalin Patra, Milu Acharya, Mitali Madhusmita Nayak, Srikanta Patnaik
Abstract: The present article establishes both crisp and fuzzy Economic order quantity (EOQ) models with proportionate discount for items with imperfect quality under learning effect. In this proposed model, first we developed the crisp inventory model for the items with imperfect quality where the defective items follow a learning curve. Finally, we discussed on two different cases of fuzzy inventory models. Case -1: Defective rate follows a learning curve and the demand rate assumed to be a triangular fuzzy number. Case -2: Defective rate, fixed ordering cost and holding cost follow the learning curve and the demand rate taken to be a triangular fuzzy number. The aim of this study is to defuzzify the total profit function by using signed distance method. Numerical examples are provided to demonstrate the developed models. Sensitivity analysis is conducted to examine the effect of number of shipments on the order quantity and total profits of the models.
Keywords: Inventory; EOQ; Imperfect quality; Proportionate discount; Triangular fuzzy number; Signed distance; Learning effects; Defuzzification.rn.

A Multi-Criterion based Integrated Methodology for the Selection of Expert System Shell
by Yashpal Singh, Rahul Mishra, S.S. Bedi, H.C. Yadav
Abstract: Expert Systems (ES) applications are being designed using Expert System Shell (ESS). Various ESSs are commonly available nowadays to design and develop the expert system in various fields. The options range from the choice of hardware platforms to the choice of computer languages and software interfaces. This study illustrates a method to select the most appropriate ESS where multiple criteria exist not only from functional requirements but also from technical and vendor-support perspectives. In the present study, an integrated approach is presented to help Expert System developers to select most suitable Expert System Shell among a set of existing alternatives for their current and future needs. For this purpose, a fuzzy TOPSIS integrated with entropy method is proposed to carry out ESS selection. The applicability of the proposed approach has been illustrated through a case study.

Tussle to Trust: Developing an Appreciative Climate for a Hydro-Power Organization in India
by Hardik Shah, Shilpa Surana
Abstract: Many large organizations are often concerned with issues of conflicts (constant tussle), building trust and engagement at workplace. Conflict between two managers, groups, or departments is commonly witnessed in organizations as a grab for power, position, or pay/budget. The conflict seeps into the groups and departments and its visible outcomes become manifested in groups and organizations--people dont see eye to eye, miscommunicate, hold resources, misinterpret communications, disobey, play politics, display low level of trust, become disengaged etc. In view of this, department heads, project heads and team leaders have been trying to answer questions like Can conflict be functional?; Can conflict help to have better decisions?; Can conflict be transformed into trust & engagement? This is critical since employee engagement is becoming an important indicator of organizational success. This research paper describes how Appreciative Inquiry (AI) has been used and applied to transform the tussle into trust & engagement. The paper illustrates use of experiential workshop methodology for different groups of managers selected based on their designation (Managers to DGM levels) and years of experience. Firstly, various conflict experiences for selected midlevel managers (Sample of 55) were discovered (in story form) as a starting point. Various themes were identified out of these stories. In the next step, they were divided into groups of 6-8 people and dreamed about the most engaging climate using visualization activities. Following this, the groups worked on action plans or mechanisms for managing tussle and developing appreciative climate of trustworthiness and engagement.
Keywords: Conflict; Appreciative Climate; Trust; Engagement.

A Framework for Sustainable Supply Chains: Evaluation of Implementation Barriers
by Bikram K. Bahinipati, Swayam S. Panigrahi
Abstract: Sustainable supply chain Management (SSCM) identifies and integrates a set of key business processes to provide products, services and information for value addition through collaborative and sustainable efforts of supply chain members. In order to accomplish this objective, sustainable supply chain practices need to be implemented to ensure a strong and healthy society without compromising the performance limits and governance, while attaining the environmental, economic, and social goals. The literature and industry experts have identified the critical inhibiting indicators for the successful implementation of SSCM practices. The sustainable supply chain evaluates different alternatives against multiple sustainable practice attributes which should be considered simultaneously to arrive at an appropriate implementation decision. The focus of this paper is to develop a framework for implementation of sustainable practices in Indian Small and Medium Enterprises (SMEs) for competitive advantage. An analytic hierarchy process (AHP) framework has been proposed for SMEs to resolve the conflicts and quantify the impact of critical inhibitors on SSCM implementation. The assessment of the priority weight of these inhibitors would help the decision makers to prioritise the action plan for implementation of SSCM practices. A sensitivity analysis is conducted to identify the sensitive points in the decision process.

An Insight into Centralized Sourcing Strategy for Enhancing Performance and Sustainability of Multi-tier Supply Network
by Avinash Bagul, Indrajit Mukherjee
Abstract: In a multi-tier supply network, sourcing strategy, consisting of supplier selection (SS) and order quantity allocation (OQA) to selected supplier(s), is a critical and challenging task for practitioners. Every player, in every tier of sourcing network, attempts to select quality conscious suppliers and optimize its own inventory cost per unit time for OQA. However, this may results in sub-optimal solution(s) for overall multi-tier supply network. Considering centralized sourcing strategy for SS and OQA may provide global best solution and sustainable supply network. This paper attempts to quantitatively illustrate inventory cost saving for coordinated centralized sourcing strategy for all tiers compared to independent decentralized sourcing strategy at individual tier in the supply network. Suitable mathematical models (single and multi-tier) and corresponding solution framework is used to determine local optima and global best solution for a comparative analysis. A real life electric goods manufacturing industry case study is used to demonstrate significant cost advantage for a centralized as compared to decentralize sourcing strategy. Sensitivity analysis with varied unit material price is also illustrated in this study.

Developing the preferred supplier relationships A case study
by Sunil Kumar C V, Srikanta Routroy
Abstract: The manufacturer-supplier relationships along the manufacturing supply chains have become the rich sources for generating the sustainable competitive advantages. Consequently in developing these relationships, often the manufacturers are inclined to have preferred supplier relationships established so as to cater their long term requirements. In this regard, a manufacturer must adopt a scientific process to favourably associate with few selected suppliers and eventually choose to develop the right suppliers in order to generate the supply base advantages over the other manufacturers. However, in practice often the right suppliers are not systematically promoted and thereby the opportunities for achieving the potential growth of manufacturing supply chains are greatly lost. Considering this issue, the current study is focused on proposing a systematic approach for establishing the preferred supplier relationships. By implementing the proposed process, a manufacturer can ensure that the right suppliers are professionally endorsed and the manufacturer-supplier relationships are optimally flourished.
Keywords: Preferred supplier concept; fuzzy analytical hierarchy process; fuzzy TOPSIS; manufacturer-supplier relationships; preferred supplier status.

Coordination Quality Index: A metric for measuring the quality of coordination efforts in humanitarian supply chain
by Anand Gurumurthy, Lijo John
Abstract: Coordination challenges in humanitarian supply chain (HSC) have plagued logistician for long in the humanitarian domain. Since coordination requires deployment of resources in terms of manpower, material and money, it is a cost center by (Balcik et al., 2010; Stephenson, 2005) all the associated members of the HSC. The effectiveness of the coordination practice has a direct consequence on the performance HSC operations. Therefore, it becomes imperative for the managers to quantify the effectiveness of the coordination activities for improving the operations of HSC. This study aims to address this gap and provide humanitarian agencies with a decision support tool to measure effectiveness of its coordination strategies in achieving the related benefits such as improved resource utilization, better information sharing, improved perception of value of coordination, streamlined organizational mandates, etc. Coordination Quality Index (CQI) is introduced to address this need. CQI is an aggregate measure of the degree of implementation of various coordination practices carried out by the humanitarian agencies. Furthermore, the application of the proposed methodology is demonstrated in the setting of Chennai Flood relief activities.The results indicate that the overall quality score obtained for coordination during the Chennai floods was moderate to low. Though, the perception of value for coordination and effectiveness of resource utilization was from moderate to high, the major reason for the poor coordination was due to the poor information sharing, large diversity of actors and lack of streamlined organizational mandates. It was also found that, though there were efforts to improve coordination between the stakeholders in HSC during the relief operation of Chennai floods, benefits of the coordination were not achieved.

A Practical Quality Management System Implementation Framework for Small-Sized Companies
by Om Prakash Yadav
Abstract: An effective quality management system is critical for having a smooth and efficient supply chain system. Establishing and maintaining quality systems is more challenging for smaller companies compared to larger organizations. This paper presents a cost effective and do-it-yourself approach to design and implement a quality management system for smaller organizations. It proposes a quality system implementation framework for small-medium sized companies to enable their transition from a no-quality system to having a more effective quality system. The study also proposes an effective continuous improvement and system maintenance plan after implementing the quality system. The proposed framework is validated using a case study of a small door manufacturing company. The findings of this study reveal several setbacks during quality management implementation and suggest means to overcome them. Benefits and results achieved by implementation of proposed framework will be useful for quality practitioners, quality managers, consultants, and engineers, especially in small companies.
