JapanJournal Article20160316This paper presents an optimized diamond structured automobile supply chain network towards a robust Business Continuity Management model. The model is necessitated by the nature of the automobile supply chain. Companies in tier two are centralized and numerically limited and have to supply multiple tier one companies with goods and services. The challenge with this supply chain structure is the inherent risks in the supply chain. Once supply chain disruption takes place at tier 2 level, the whole supply chain network suffers huge loses. To address this challenge, the paper replaces Risk Analysis with Risk Ranking and it introduces Supply Chain Cooperation (SCC) to the traditional Business Continuity Plan (BCP) concept. The paper employed three statistical analysis techniques (correlation analysis, regression analysis and Smart PLS 3.0 calculations). In this study, correlation and regression analysis results on risk rankings, SCC and Business Impact Analysis were significant, ascertaining the value of the model. The multivariate data analysis calculations demonstrated that SCC has a positive total significant effect on risk rankings and BCM while BIA has strongest positive effects on all BCP factors. Finally, sensitivity analysis demonstrated that company size plays a role in BCM.Kharazmi UniversityInternational Journal of Supply and Operations Management238313592420160201Green Supply Chain Management Practices’ Effect on the Performance of Turkish Business Relationships9821002265210.22034/2015.4.02ENMohammad HosseinZavvar SabeghDepartment of Industrial Engineering, Faculty of Engineering, Kharazmi University, Tehran, IranYucelOzturkOgluFaculty of Economics and Administrative Sciences, International Logistics Management, Yasar University, Izmir, TurkeyTaebokKimSchool of Logistics, Incheon National University, Incheon, South KoreaJournal Article20160416The main aim of the study is to examine the influence of both external and internal actors on green supply chain management (GSCM) practices. By the way, this paper is to provide a first-hand understanding about the procedures taken by Turkish business firms and their logistics providers and supply chain business firms to operate in an environmental friendly supply chain.

We collect data from 2014 May to 2015 July through the Turkish companies. More than 180 companies have contributed in this great research. We analyzed data by statistical methods. One of the important results is the third party logistics service providers influence firms have a proactive green behavior.Kharazmi UniversityInternational Journal of Supply and Operations Management238313592420160201Capacitated Windy Rural Postman Problem with Several Vehicles: A Hybrid Multi-Objective Simulated Annealing Algorithm10031020261910.22034/2015.4.03ENMasoudRabbaniCollege of Engineering, University of Tehran, Tehran, IranSafouraFamil AlamdarSchool of Industrial Engineering, College of Engineering, University of Tehran, Tehran, IranHamedFarrokhi-AslSchool of Industrial Engineering, Iran University of Science & Technology, Tehran, IranJournal Article20151112This paper presents the capacitated Windy Rural Postman Problem with several vehicles. For this problem, two objectives are considered. One of them is the minimization of the total cost of all vehicle routes expressed by the sum of the total traversing cost and another one is reduction of the maximum cost of vehicle route in order to find a set of equitable tours for the vehicles. Mathematical formulation is provided. The multi-objective simulated annealing (MOSA) algorithm has been modified for solving this bi-objective NP-hard problem. To increase algorithm performance, Taguchi technique is applied to design experiments for tuning parameters of the algorithm. Numerical experiments are proposed to show efficiency of the model. Finally, the results of the MOSA have been compared with MOCS (multi-objective Cuckoo Search algorithm) to validate the performance of the proposed algorithm. The experimental results indicate that the proposed algorithm provides good solutions and performs significantly better than the MOCS.Kharazmi UniversityInternational Journal of Supply and Operations Management238313592420160201Power Imbalance in Collaboration Relationships10211034265610.22034/2015.4.04ENDrissEssabbarMoroccan School of Engineering Sciences, Marrakech, MoroccoMariaZrikemTIM Laboratory-ENSA, BP 575 Abdelkarim Khattabi, Marrakech, MoroccoMarcZolgadriPhenics-LISMMA Laboratory EA2336 Supmeca, 3 rue Fernand Hainaut, Paris, FranceJournal Article20160117Power plays a significant role in many organizational theories such as resource dependency theory and transaction cost economics. It allows the strong companies to win more than others, or more broadly, to coerce others to do what they would not otherwise do. Power can seriously affect the confidence and commitment between parties. This paper aims to analyze the power concept in inter-organizational relationships. We discuss some formal results modeling power and the set of elements and property necessary to understand these concepts. We also proposed a "power generation process" that allows to describe how power is developed in a relationship according to dependency. As far as we were able to browse the scientific literature, these are the first attempts to suggest a robust foundation of the power theory.Kharazmi UniversityInternational Journal of Supply and Operations Management238313592420160201A Model for Cooperative Advertising and Pricing Decisions in Manufacturer-Retailer Supply Chain with Discount: A Game Theory Approach10351063265010.22034/2015.4.05ENAbolfazlKazemiFaculty of Industrial and Mechanical Engineering, Qazvin Branch, Islamic Azad University, Qazvin, IranZohrehSaeedMohammadiFaculty of Industrial and Mechanical Engineering, Qazvin Branch, Islamic Azad University, Qazvin, IranJournal Article20150822Coordinating the supply chain is among the most important subjects that is extensively addressed in the related literature. If a supply chain is to be coordinated, it is equivalent to say that we must solve a problem related to competition and cooperation. The game theory is obviously one of the most effective methods to solve such problems, in which the players of the supply chain are assumed to engage in cooperative and non-cooperative games. The current study aims to coordinate a two-level supply chain consisting of a manufacturer and a retailer. This will be achieved using cooperative advertisement along with pricing decisions such that the manufacturer offers a price discount to the retailer and the demand is affected by pricing and advertisement. Cooperative advertisement is a coordinated effort made by all the members of the supply chain to increase the customer demand, in which the retailer does the local advertisement and the manufacturer pays for a portion or all the costs of the retailer advertisement. We consider two models for manufacturer-retailer relation using the game theory: the manufacturer-Stackelberg and the retailer-Stackelberg games with asymmetric power distribution.Kharazmi UniversityInternational Journal of Supply and Operations Management238313592420160201Inventory Model for Deteriorating Items with Quadratic Time Dependent Demand under Trade Credits10641078262010.22034/2015.4.06ENRakeshTripathiGraphic Era University, Dehradun (UK) IndiaDineshSinghHead

SGRRPG College Dehradun (UK) IndiaJournal Article20141107In this paper, an EOQ model is developed for a deteriorating item with quadratic time dependent demand rate under trade credit. Mathematical models are also derived under two different situations i.e. Case I; the credit period is less than the cycle time for settling the account and Case II; the credit period is greater than or equal to the cycle time for settling the account. The numerical examples are also given to validate the proposed model. Sensitivity analysis is given to study the effect of various parameters on ordering policy and optimal total profit. Mathematica 7.1 software is used for finding optimal numerical solutions.Kharazmi UniversityInternational Journal of Supply and Operations Management238313592420160201Supplier Selection in Three Echelon Supply Chain & Vendor Managed Inventory Model Under Price Dependent Demand Condition10791101265110.22034/2015.4.07ENMohammadSohrabiDepartment of industrial engineering, PNU University, Tehran, IranParvizFattahiDepartment of Industrial Engineering Bu Ali Sina University, Hamadan, IranAmirKheirkhahDepartment of Industrial Engineering Bu Ali Sina University, Hamadan, IranGholamrezaEsmaeilianDepartment of Industrial Engineering PNU University, Isfahan, IranJournal Article20160316This paper, considers the supplier selection in three echelon supply chain with Vendor Managed Inventory (VMI) strategy under price dependent demand condition. As there is a lack of study on the supplier selection in VMI literature, this paper presents a VMI model in supply chain including multi supplier, one distributer and multi retailer that distributer selects suppliers. Two class models (traditional vs. VMI) are presented and we compare them to study the impact of VMI on supply chain and supplier selection. As the proposed model is a NP-hard problem, a meta-heuristics namely Harmony Search is employed to optimize the proposed models. We show that how the VMI system can effect on supplier selection and can change the set of selected suppliers. Finally the conclusion and further studies are presented
