ISM approach for modelling drivers to practices of green supply chain management in Jordanian industrial firms
by Abbas Al-Refaie, Dina Momani
Abstract: Green supply chain management (GSCM) has been considered by the many firms as a feasible decision to reduce the environmental and improving business performance. This research utilizes interpretive structural modeling (ISM) methodology to model the relationships between eight key drivers of GSCM in Jordanian industrial firms. Data was collected thirty experts from industrial organizations and academia. Structural self-interaction matrix is developed and then adopted to construct the reachability matrices. The results of ISM model revealed that government regulations and legislations pressure is the motivator driver of stakeholder pressure, global competition, financial factors, and awareness level of customers. These drivers enforce management commitment to the adoption of GSCM practices. In return, industrial firms gain preferential treatment and incentives. In conclusion, pressures from government, customers, and management are required to drive the adoption of GSCM practices in Jordanian industrial firms. Moreover, management commitment is crucial in providing sufficient resources to accomplish successful adoption of GSCM practices. Finally, the ISM model developed in this research shall provide valuable guidance to decision makers in government, as well as management of industrial firms on the key drivers of GSCM that need more attention during planning, implementation and evaluation during the downstream and upstream of product life.

Postponement and international transfer in global supply chains
by Thomas Ngniatedema, Thierry Romual Dzati Kamga, Louis Aimé Fono, Georges Dieudonné Mbondo, Suhong Li
Abstract: In this paper, we develop an analytical model for form postponement in global supply chain subject to variations in international transfers and tariffs, in service levels and in deviation from a supply delivery schedule that falls within a window. We examine the benefits of postponement under the influence of these factors, and we derive the necessary conditions for a strategic choice of both the 'postponement timing', (early or delayed differentiation) and the 'decoupling points', (early or late shipping) under decoupled and non-decoupled systems. The study shows when one type of the strategies is more beneficial than the other. Our analysis indicates that the boundaries of a delivery window, the point of differentiation, the point of export, the safety factor, and the relative production cost differences across countries play an important role under postponement. We use the production of Desk Jet printers at Hewlett Packard to illustrate the applicability of this model.
Keywords: form postponement; delivery window; delivery performance; global supply chains modelling.
Inventory policies for maximum fixed life-time product with quadratic demand under permissible delay in payments for a single supplier-two retailers
by Nita H. Shah, Mrudul Y. Jani, Urmila Chaudhari
Abstract: In this article, we study inventory policies with permissible delay in payment from a single supplier to two retailers. We consider the product with maximum fixed-life time deterioration as loss of utility is the real scenario of products like fruits, vegetables, juices, etc. Here, time dependent quadratic demand is discussed which is suitable for the products whose demand increases primarily and afterward it starts to decrease. First, we discuss the centralised inventory system in which supplier and retailers willingly take joint decision. Next we address the model with decentralised policy in which supplier and both retailers take individual decisions. The objective is to minimise the total cost in centralised and decentralised policy with respect to cycle times of supplier and two retailers. The model is supported with numerical examples. Sensitivity analysis is carried out to derive insights for decision-maker.
Keywords: inventory control; permissible delay in payments; centralised and decentralised policy; maximum fixed life-time.
Greening of humanitarian supply chain with focus on logistics
by Ammar Jilani, Yousaf Ali, Muhammad Waseem Khan
Abstract: Natural disasters and the conventional responses to the disasters disturb the environment and all the living and non-living things surround it. By both scenarios, disaster and logistical response, environment is further damaged as bulk of carbon emissions add up to the already fragile environmental health. This research explores the issues due to natural disasters and the response to these disasters, and to make the humanitarian logistics green so that further damage could be reduced. Since there exists a low quantity of literature regarding a green or sustainable humanitarian logistics, for the sake of comparison, the method of introduction of sustainable concepts in commercial logistics has been highlighted. Those very concepts which have common grounds with humanitarian logistics have been borrowed, restructured, and introduced particularly considering the constraints and resource availability faced during humanitarian operations. Debatable points have been extracted from the review of literature, organised into hypotheses, tested through the collection of data, and analysed through ANOVA. The major findings suggested to decrease the vehicle load volume which would result in an increase of vehicle fill-rate, and correspondingly less damage would be done to the environment due to the logistics.
Keywords: humanitarian logistics; disaster management; humanitarian supply chain; green humanitarian supply chain; ANOVA.
Evaluation of manufacturing unit location in Russia - European trade and logistics perspective
by Yulia Panova, Olli-Pekka Hilmola
Abstract: The research examines the location problem of a manufacturing unit as a two-level process. Firstly, at the upper level, macro-analysis of the eight Russian regions was conducted to estimate the potential of placing the unit on one of these. The location-selection decision was made via the most frequently used multi-criteria evaluation approach (AHP) based on the eight decision factors. At the second step, the analysis on micro-level was carried out to define the specific location within the selected region. In particular, the research looks at the industrial zone of Ust-Luga seaport located in the North-West region. The expected multiplicative effect, which can be derived from an integrated development of manufacturing and seaport as well as railways, was analytically evaluated. Application to the described agglomeration economies help to understand, why economic activity clusters together.
