In this paper, the approach of Demand Driven Distribution Resource Planning (DDDRP) is proposed in order to optimize the distribution flow in the supply chain. The purpose is to manage all sources of variability "operational, management, supply and demand", while improving the traditional methods as Distribution Resource Planning (DRP). A literature review is presented about the impact of variability on distribution flow, and the solutions proposed in this context. Then, a general study of distribution industries is investigated in order to apply the DDDRP method; we show the buffer positioning in the distribution network, and the profile and levels for these buffers. After the dynamic adjustment, we present the Demand Driven Planning and the execution based on the net flow equation. The results discuss the approach and the steps of the implementation in the distribution industry. http://www.ijsom.com/article_2774_85a4efc7d0e65528f1dd198437ecc1f1.pdf Supply Chain Management DRP, DDDRP Inventory management Bullwhip effect eng Kharazmi University International Journal of Supply and Operations Management 23831359 23832525 2019-02-01 6 1 11 29 10.22034/2019.1.2 2775 مقاله پژوهشی Integration of P-hub Location Problem and 3M Supply Chain M.B.

The problem is formulated as a mixed integer programming model and solved using GAMS software. As the developed model is a mixed integer non leaner programming and NP-hard, a new algorithm for re-formulation is proposed to change it to a mixed integer leaner programming and also a new heuristic algorithms is proposed to solve it in a reasonable time. To prove the applicability of the model, the well-known real CAB data set is used. Numerical examples show the benefit of the proposed model in both solution time and result quality. http://www.ijsom.com/article_2775_f0eba795316cdd9a040b97db37616426.pdf Multi-level Multi-period Supply chain performance elements P-hub median problem Production planning eng Kharazmi University International Journal of Supply and Operations Management 23831359 23832525 2019-02-01 6 1 30 50 10.22034/2019.1.3 2778 Integrated Production and Distribution in Milk Supply Chain under Uncertainty with Hurwicz Criterion Achraf Touil achrafchen@gmail.com 1 Abdelwahed Echchatbi echchatbi@gmail.com 2 Abdelkabir Charkaoui charkaoui.a@gmail.com 3 Industrial Management and Innovation Laboratory of Engineering, Faculty of Sciences and Technology, Hassan 1st University, Settat, Morocco Industrial Management and Innovation Laboratory of Engineering, Faculty of Sciences and Technology, Hassan 1st University, Settat, Morocco Industrial Management and Innovation Laboratory of Engineering, Faculty of Sciences and Technology, Hassan 1st University, Settat, Morocco In this paper, we propose a credibility-based fuzzy mathematical programming model for integrating the production and distribution in milk supply chain under uncertainty. The proposed model is a mixed integer linear programming, which takes into account technological constraints and aims to maximize the total profit including the total costs such as production, storage, and distribution. To bring the model closer to real-world planning problems, the objective function coefficients (e.g. production cost, inventory holding and transport costs) and other parameters (e.g., demand, production capacity, and safety stock level), are all considered fuzzy numbers. In the uncertain environment, the most known criteria widely employed are optimistic and pessimistic value criterions. Both criteria present some deficiency. For the optimistic criterion, it suggests an audacious who is attracted by high payoffs (low cost), while for the pessimistic criterion, it suggests a conservative decision-maker who tries to make sure that in the case of an unfavorable outcome (loss), there is at least (in most) a known minimum payoff (loss maximum). To overcome these problems, the Hurwicz criterion is used for the concerned problem. By varying the value of θ, it can balance the optimistic and pessimistic levels of the decision makers. Moreover, the different property of the credibility measure is used to build the crisp equivalent model, which is a MILP model that can solve, by using a commercial solver such as GAMS. Finally, numerical results are reported for a real case study to demonstrate the efficiency and applicability of the proposed model. http://www.ijsom.com/article_2778_2e0f2f7c3e958f03c36b8339977f53b9.pdf Milk supply chain Production-Distribution Credibility theory, Hurwicz criterion eng Kharazmi University International Journal of Supply and Operations Management 23831359 23832525 2019-02-01 6 1 51 56 10.22034/2019.1.5 2777 مقاله پژوهشی The Effect of Green Supply Chain Practices on Operational Performance: Bench-marking between Shell and Co-operation Petroleum Company in Egypt Yasser Said yasseressam30@yahoo.com 1 Department of Foreign Trade Logistics, International Transport and Logistics Institute for Postgraduates Studies, Arab Academy For Science, Technology, and Maritime Transport, Cairo, Egypt This study aimed to determine the applicability to which green supply chain practices employed by Shell and Co-operation Petroleum Company in Egypt. Additionally, the impact of Green Supply Chain practices on the operational performance of each company. The results, based on benchmarking, were statistically analyzed by Fischer analysis. Concerning the company's practices of green procurement, the results revealed highly significant differences (p<0.0001) in requiring Suppliers to have ISO 14001, purchasing materials that contain green attributes, suppliers on specific environmental criteria and procure products that are made using recycled packages between both companies. Concerning the company's green manufacturing practices, the results revealed highly significance differences (p<0.0001) in produce products that have packages, use life cycle assessment to evaluate environmental load, replacing hazardous substances with that are environmentally friendly, minimize the use of materials in packaging, encourage reuse of products and recycled materials, reducing the size of packaging, and cooperating with suppliers to standardize packaging between the both company. Concerning the company's practices of reverse logistics, the results revealed highly significant differences (p<0.0001) in dealing with disposal, processing returned merchandise, and repackaging product. Concerning the Company's operational performance with respect to the implementation of green supply chain practices the results revealed highly significant differences (p<0.0001) in quality, safety, delivery, and flexibility between Shell and Co-op companies. The work illustrated that green supply chain practices have a profound effect on the operational performance in Shell Company making it number one in the lubricant industry in Egypt. http://www.ijsom.com/article_2777_ba26e2b7c6c65052b9bcd7f55aae3c51.pdf Green supply chain practices Shell Egypt Co-operation Petroleum Company Statistical methods Operational performance eng Kharazmi University International Journal of Supply and Operations Management 23831359 23832525 2019-02-01 6 1 57 66 10.22034/2019.1.4 2776 مقاله پژوهشی An Application of Cooperative Grey Games to Post-Disaster Housing Problem Emad Fathi Hussien Qasim emadqasim@yahoo.com 1 Sırma Zeynep Alparslan Gok zeynepalparslan@yahoo.com 2 Osman Palanci osmanpalanci@sdu.edu.tr 3 Department of Mathematics, Faculty of Arts and Sciences, Suleyman Demirel University, Isparta, Turkey Department of Mathematics, Faculty of Arts and Sciences, Suleyman Demirel University, Isparta, Turkey Department of Business Administration, Faculty of Economics and Administrative Sciences, Suleyman Demirel University, Isparta, Turkey This paper shows that cooperative grey game theory can help us to establish a fair cost share between private organizations for supporting the temporary housing problem by using facility location games under uncertainty. Temporary accommodation may be a method that ought to get started before the tragedy happens, as a preventative pre-planning. In spite of being temporary constructions, the housing buildings are one of the most essential parts to produce in emergency situations, to contribute to the reconstruction and to recover better. Our study is based on a default earthquake in Izmir of western Turkey. A number of tents are being built in the following three cities, Aydin, Usak, and Balikesir near Izmir as illustrated in Figure 1. Two companies are selected, one is local and another is foreign to distribute the tents in a fair way between the three cities. For this purpose, we use cooperative grey game theory to help us to define a fair cost allocation between private organizations for supporting the housing problem by using facility location games under uncertainty. http://www.ijsom.com/article_2776_d0abfb34e15a98c53d62ba5b90919058.pdf Temporary housing Earthquake Cooperative grey games Grey numbers Facility location situations eng Kharazmi University International Journal of Supply and Operations Management 23831359 23832525 2019-02-01 6 1 67 87 10.22034/2019.1.6 2779 مقاله پژوهشی A Multi-stage Stochastic Programming Approach in a Dynamic Cell Formation Problem with Uncertain Demand: a Case Study Davood Shishebori shishebori@yazd.ac.ir 1 Saeed Dehnavi ourgod2008@gmail.com 2 Department of Industrial Engineering, Yazd University, Yazd, Iran Department of Industrial Engineering, Yazd University, Yazd, Iran This paper addresses a dynamic cell formation problem (DCFP) including a multi-period planning horizon in which demands for each product in each period are different and uncertain. Because the demand uncertainty is considered as stochastic data by discrete scenarios on a scenario tree, a multi-stage nonlinear mixed-integer stochastic programming is applied such that the objective function is minimizing of machine purchase costs, the operating costs, both inter and intra-cell material handling costs, and the machine relocation costs over the planning horizon. The main goal of the current study is to determine the optimal cell configuration in each period in order to achieve the minimum total expected costs under the given constraints. The nonlinear model is transformed into a linear form to this reason that GAMS can get to global optimal solutions in linear models. In order to find the optimal solutions, by using the GAMS for small and medium-sized problems, the optimal solutions are obtained. They applied in two bounds namely the Sum of Pairs Expected Values (SPEV) and the Expectation of Pairs Expected Value (EPEV). Also, according to the scenario-based model, the efficiency of two suggested bounds is shown in terms of the computational time. Finally, a practical case study is presented in detail to illustrate the application of the proposed model and it's solving method. The results show the efficiency of using SPEV and EPEV for several random examples as well as the proposed case study. http://www.ijsom.com/article_2779_75adbd62dce9590d6e17e009124b3d01.pdf Dynamic cell formation problem Multi stage stochastic programming Expectation of pairs expected value eng Kharazmi University International Journal of Supply and Operations Management 23831359 23832525 2019-02-01 6 1 88 93 10.22034/2019.1.7 2780 Supply Chain Management Information System for Curriculum Management Based on The National Qualifications Framework for Higher Education Artaphon Chansamut artaphon.c@mail.rmutk.ac.th 1 Pallop Piriyasurawong 2 Faculty of Technical Education, King Mongkut’s University of Technology, North Bangkok, Thailand Faculty of Technical Education, King Mongkut’s University of Technology, North Bangkok, Thailand The purposes of this research were (1) To develop of supply chain management-information system for curriculum management Based on National Qualifications Framework for Higher Education.
