  • A fuzzy imperfect quality inventory model with proportionate discount under learning effect   Order a copy of this article
    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.

  • Tussle to Trust: Developing an Appreciative Climate for a Hydro-Power Organization in India   Order a copy of this article
    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.

    by Ravinder Kumar 
    Abstract: Due to limited reserve potential of petroleum and natural gas, eco-conservation restriction on hydroelectric projects followed by geopolitical perception of nuclear power; coal can be considered as the backbone for the present energy production scenario. From a purely economic point of view, the maximisation of overall profit of coal-fired thermal power plant is a very complex activity. In the present work, the focus is given to identify the redundancy level on various components or subsystems of the coal fired power plant using modelling, simulation and optimisation tools, so and so, that the overall profit of coal-fired plant could be maximised. Simulated annealing technique for optimisation has been used for maximisation of profit in terms of net present value (NPV) of complex coal fired power plant. At maximum NPV, the optimum numbers of redundancies on boiler sub-system, condensate extraction pump and boiler feed water pump are found to be one, three and one respectively.

  • Coordination Quality Index: A metric for measuring the quality of coordination efforts in humanitarian supply chain   Order a copy of this article
    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.

  • An Insight into Centralized Sourcing Strategy for Enhancing Performance and Sustainability of Multi-tier Supply Network   Order a copy of this article
    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   Order a copy of this article
    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.
