      • SUPPLY CHAIN RESILIENCE – A SYSTEMATIC LITERATURE REVIEW

        Sonia Irshad Mari,Young Hae Lee(이영해),Muhammad Saad Memon 한국경영과학회 2013 한국경영과학회 학술대회논문집 Vol.2013 No.5

        Supply chain today are more vulnerable than ever. Serious financial losses to organizations due to supply chain disruptions requires development of resilient supply chains. There is broad evidence by both the researchers and practitioners, that there is a great need to make more resilient supply chains due to the increasing complexities and in order to face and compete in this unstable, unpredictable and turbulent business environment. Due to importance of topic, the aim of this paper is to provide systematic literature review that provides comprehensive knowledge from dynamic and static perspective. Our research follows the systematic literature network analysis (SLNA) methodology for developing evidence informed knowledge management process. The present literature review gives a brief look at supply chain resilience and the emerging trends and issues in this area. The identified research directions can be helpful for the development of models for handling supply chain resilience issues.

      • Analyzing Traceability Optimization for Enhancing Product Safety in Supply Chain

        Muhammad Saad Memon,Young Hae Lee(이영해),Sonia Irshad Mari 한국경영과학회 2013 한국경영과학회 학술대회논문집 Vol.2013 No.5

        Recent severe product recalls stimulate the manufacturers to limit risk associated with products in order to save consumer health and increase the consumer trust. Therefore implementing efficient safety management system from raw material purchasing to delivery of final product to its customer is major concern of all industries. Effectual traceability system is now major concern of all supply chain partners. Effective design of traceability system may turn out to be significant tool for managing product safety issue in batch production system. Traceability associated literature only focus on technological perspective, however traceability and its implications on product safety is rarely available in literature. The aim of this paper is to analyse the traceability phenomena for enhancing product safety by reducing the batch dispersion.

      • A Grey System Theory Based Approach for Supplier Evaluation and Selection

        Muhammad Saad Memon,Young Hae Lee(이영해),Sonia Irshad Mari 한국경영과학회 2014 한국경영과학회 학술대회논문집 Vol.2014 No.5

        It is extremely difficult to successfully maintain the performance of manufacturing firm without considering a suitable set of suppliers. The effective estimation of supplier’s capabilities are real arduous tasks for managers. The objective of this paper is to develop framework for reducing the risks associated with suppliers. Supplier selection decision consist of stochastic and recognitive uncertainties and to deal with these uncertainties we use grey systems theory based approach. We first identified the important criteria which affect the supplier selection decision and then proposed a grey goal programming based approach to select suitable set of suppliers and optimal order allocation to each selected supplier.

        New circle clustering algorithm for vehicle routing problem

        Jingzhe Li(이경철),Young Hae Lee(이영해),Sonia Irshad Mari(소니아 이르샤드) 한국SCM학회 2015 한국SCM학회지 Vol.15 No.1

        Vehicle routing problem has been widely solved by the various algorithms. The sweep algorithm is one of the frequently used algorithms in which the fan-shaped area is calculated after the grouping considering vehicle’s capacity and polar-angle routes in one plane. In this paper, a circle algorithm is proposed which can be used in the particular situations where stops are scattered in a lantern ring area. The proposed circle algorithm considers stops and depot on 2D plane and the plane is divided into ring-shapes with its center of weight. Mathematical models for calculating of vehicle routing distance for both algorithms are derived. Both algorithms are compared based on the derived mathematical models and simulation experiments. The result shows that circle algorithm performs better than sweep algorithm. In order to take advantage of both algorithms, the combined circle and sweep algorithm is suggested for practical use.
