Deriving vulnerability indicators for crop production regions in Indonesia

Food supply is considered as one of the most vulnerable to the effects of climate change. Higher temperature and changes in rainfall patterns and intensity may adversely impact crop production, which will eventually affect the food supply. Consequently, adaptation strategies should be devised to minimize the potential adverse impacts and maximize its potential benefits. The adaptation strategies should be devised by considering factors contributed to causing vulnerability following the concept of food supply chain, starting from production to consumption. This study focuses on identifying the contributed factors to vulnerability of crop production regions in Indonesia. The contributed factors were identified by defining indicators for each component of the food supply chain using an example of crop production centers in Indonesia, the West Java Province. The identification considers existing issues of the food supply chain, covering aspects of production, post-harvest and storage, distribution, and consumption, based on the field surveys conducted in Indramayu district of the West Java, the main grower of paddy production, and Garut district of the West Java, the main grower of corn production. The selection of the vulnerability indicators was also considered the data availability for the study area. The analysis proposed a list of indicators classified into production, post-harvest and storage, distribution and consumption that are proposed to assess the regional vulnerability of crop production regions in Indonesia. This result is expected to contribute in understanding the process of devising climate change adaptation intended for enhancing food supply resilience to climate change.

Sustainable supply chain maturity model

The problem of sustainability is gaining more and more importance. It is because of the increasing pressure from the market and the public administration to improve the environmental and social conditions for all. The issue of sustainability is implemented into business and in particular into supply chains as an important element of management. Despite many works regard to the concept of sustainable supply chain there is still a lack of the complex models that will help to understand and identify the current position of the supply chain and give the feedback which actions are expected to be improve to achieve the next level of maturity. The main aim of the paper is an attempt to conceptualize the problem of maturity in supply chain in the context of sustainability. The improved conceptual model will be introduced.

Apparent contradictions effective and efficient supply chain: Time pressure and eliminating the stock

Responsive performance as a response to all the requirements of customers and consumers, at first glance, requires plenty of time and a high level of inventories in order to service the customers and consumers in a quality manner. However, in recent decades, along with the development of the concept of supply chain, in theory and in practice, proves the opposite: in conditions of the high level of competition and the speed of change in the needs and demands of consumers, the speed of orders execution is often the key performances in many supply chains. As regards inventory, competitive supply chain tends to hold stocks only for the needs of production during or even minimum safety stocks over it. Companies are trying to organize their supply chains so as to achieve the quality, completeness and reliability of delivery in the shortest possible time and with minimal inventory. Such operational capability is achieved and the efficiency and competitiveness of the supply chain, that is, “operational excellence” can be solve contradiction of the time compression and the stock reduction, compared to the total satisfaction of customers.. This paper will be discussed models, methods and techniques of management in the supply chain that allow such an organization.

Enhancing BRICS integration: a cloud-based green supply chain concept

Today, BRICS - a five nation active group - represents an emerging power that aims to increase its economic integration in response to new global challenges. While many companies in the BRICS group are opening up new geographical industry clusters, changing their IT landscape, and contributing to global climate change concerns, others are not fully prepared, or ready, to do so. This study explores the applicability of mutually beneficial cloud-based green supply chain system among BRICS nations to help achieve development targets while mitigating the environmental impacts associated with rapid development and industrialisation. Data on the BRICS countries trade potential and patterns is reviewed to get a sense of the movement of goods and services between the BRICS nations. Although regulatory barriers and inter-country coordination pose significant challenges for meeting the promise of BRICS trade cooperation, the adoption of new cloud-based IT technologies, new innovations and new thinking remains an important enabling driver of green supply chain management and needs to be explored.

Mechanism of Green Supply Chain: In the Manufacturing Industry of U.S

In last couple of decades, green supply chain become a competitive strategy for survival in tough competitive market. There is no doubt that a number of European countries already adopted green supply chain practices successfully. Green supply chain concept gives a way to conduct a sustainable business and also prevent to environments from harmful effects of chemicals and pollution. On the other hand, green supply chain also reduce the cost of the end-to-end supply chain [1]. Many visible and invisible factors are exists in the process of reverse logistics but main factors are social reasons, Economic, Legal & Environment policies. But the economic factor is the directly involve in the implementation of reverse logistics. This paper will help to understand the phenomena involved in green supply chain management implementation as well as the barriers and drivers involved in green supply chain execution phases.

Green supply chain management performance within the Thai hotel industry: a structural equation model

This research used first and second order confirmatory factor analysis and structural equation modelling with AMOS 21 software to analyse green supply chain management (GSCM) performance within Thailand's 3-star, 4-star, and 5-star hotel industry. The final sample of 325 managers revealed that service users, suppliers, and green practices have a direct influence on the Thai hotel industry's GSCM performance. Further, it was found that the same drivers had an indirect impact on GSCM performance through service users. Also, competitors, laws, and environmental adherence have an indirect influence through suppliers. It was also determined that positive financial results can be obtained when hoteliers adjust their practices to conform to green supply chain concepts. Hoteliers should also establish networks of green hotels, while also implementing the 3Rs of reuse, reduce, and recycle. Hoteliers should also focus on using green energy, establishing green attitudes, and raising awareness amongst staff through green environment workshops.

Regulatory framework for the development of the green supply chain: EU vs Serbia

Business practice indicates that besides the economic and social motives, the orientation towards the usage of green initiatives within the supply chain is mostly determined by strong legislative regulations which exist within the field, and which get more complex as the time passes. However, there is no uniformity regarding the treatment of regulation importance for the usage of the green supply chain concept worldwide. The empirical evidence shows that the degree of regulation of this issue, with the biggest number of accompanying directives is the highest within the territory of Europe, i.e. EU, while, for example, economic reasons of using this concept are more dominant in the USA, with the less developed regulations, which come as second. The rest of the world still recognizes vaguely the importance of the green supply chain concept, thus setting its implementation within these parts of the globe at the beginning stage, and making the motives which drive the implementation pretty unclear and non-differentiated. Therefore, the issue of the regulatory framework which represents the development guideline for green initiatives within the supply chain is very complex and specific and represents the basic preoccupation of the analysis within this paper. The entire paper is divided into two parts. Within the first part of the paper chosen EU directives oriented towards the regulation of specific issues and areas of managing the green supply chain are treated in detail. The second part of the paper is dedicated to the review of the legislative framework which treats the identical field, only within the Republic of Serbia. Precisely, an analysis is carried out to which degree the Serbian regulatory framework recognizes, appreciates and encourages the implementation of green initiatives within the supply chain and what is the general position of that framework compared to the one set by the EU. The aim of the paper is to identify the compatibility degree of the Serbian regulatory framework and the one set by the EU, as well as to recognize potential incompatibilities or shortcomings within the system of Serbian regulation which defines the green initiatives. Since the ultimate strategic goal of Serbia is to become a full member of the EU, the highest possible degree of harmonization of these two regulatory systems is needed, which shall be checked by the analysis within this paper.

Analyzing the Effect of Express Orders on Supply Chain Costs and Delivery Times

Delivery time differentiation is a supply chain concept that has been implemented in various industries, but not yet in the automotive industry. One reason is that the effects of delivery time differentiation on the supply chain are not well understood. The BMW Group, for instance, has considered offering an express order option, where express orders bypass standard orders in the supply chain processes to achieve short delivery times. Express orders distort planning processes, increase operations cost, and increase the delivery times of standard orders, however the effects have not been quantified yet. This study analyzes the impact of express orders on the supply chain, when express orders are built‐to‐order. To understand the supply chain consequences of express orders better, we analyzed the relevant supply chain processes at BMW Group. We determine the effect that built‐to‐order express orders have on delivery times and on component demand. To analyze the effect of introducing express orders on expected delivery times and expected cost, we use queuing theory and derive expressions for the transient behavior of a discrete time batch queue. Our analyses indicate that many supply chain processes are only marginally affected. However, the orders to the suppliers become considerably more uncertain, which must be compensated by additional safety stock. Our results indicate that express orders can be an attractive option for BMW and other automotive companies. If the fraction of express orders stays at a reasonable level, express orders can be delivered within about two weeks.

What Accounts for the Growth of Carbon Dioxide Emissions in Advanced and Emerging Economies? The Role of Consumption, Technology and Global Supply Chain Participation

This paper examines the driving forces behind the growth in carbon dioxide emissions in forty advanced and emerging economies between 1995 and 2008. We use the global supply chain concept introduced in Timmer et al. (2014) to measure CO2 emissions in internationally fragmented production networks and embed the concept in structural decomposition analysis. Our findings suggest that rising levels of domestic consumption are related to increased carbon dioxide emissions in both advanced and emerging economies. A substantial share of CO2 emissions growth in emerging economies is accounted for by increased participation in global supply chains. However, even for countries that rapidly integrated in global production networks, such as China, rising domestic consumption accounts for the majority of territorial emissions.

Sustainable supply chain models for base of the pyramid

Institutional barriers and constraints in developing countries require new supply chain models where economic, social and ecological aspects are integrated. Sustainable supply chain management discourse has focused on ecological aspects and neglected social issues, while Base of the Pyramid studies have neglected ecological considerations. This study links the sustainable supply chain management discourse with insights from Base of the Pyramid studies in order to suggest an integrated sustainability perspective. This work adopts a multiple case study design based on secondary data analysis in order to investigate supply chain concepts of 18 successful products and develop sustainable supply chain models in the areas of sourcing, making and delivering. Findings suggest that by employing localized and simplified approaches, companies targeting low-income markets can overcome existing local institutional barriers. We conclude that employing simplified and localized approaches to supply chains and simultaneously integrating local communities in the value creation activities can serve as success factors. Therefore, by linking sustainable supply chain with the Base of the Pyramid strategies discourse, we fill an important research gap in the literature. From a practitioner's perspective, the derived supply chain models serve as best practices for managers of multi-national companies, local entrepreneurs, non-governmental organizations and political institutions designing, operating and regulating supply chains for low-income markets.

Supplier selection in agile supply chain

Purpose The recent global market trend is seemed enforcing existing manufacturing organizations (as well as service sectors) to improve existing supply chain systems or to take up/adapt advanced manufacturing strategies for being competitive. The concept of the agile supply chain (ASC) has become increasingly important as a means of achieving a competitive edge in highly turbulent business environments. An ASC is a dynamic alliance of member enterprises, the formation of which is likely to introduce velocity, responsiveness, and flexibility into the manufacturing system. In ASC management, supplier/partner selection is a key strategic concern. Apart from traditional supplier/partner selection criteria; different agility-related criteria/attributes need to be taken under consideration while selecting an appropriate supplier in an ASC. The paper aims to discuss these issues. Design/methodology/approach Therefore, evaluation and selection of potential supplier in an ASC have become an important multi-criteria decision making problem. Most of the evaluation criteria being subjective in nature; traditional decision-making approaches (mostly dealing with objective data) fail to solve this problem. However, fuzzy set theory appears an important mean to tackle with vague and imprecise data given by the experts. In this work, application potential of the fuzzy multi-level multi-criteria decision making (FMLMCDM) approach proposed by Chu and Velásquez (2009) and Chu and Varma (2012) has been examined and compared to that of Fuzzy-techniques for order preference by similarity to ideal solution (TOPSIS) and Fuzzy-MOORA in the context of supplier selection in ASC. Findings It has been observed that similar ranking order appears in FMLMCDM as well as Fuzzy-TOPSIS. In Fuzzy-MOORA, the best alternative appears same as in case of FMLMCDM as well as Fuzzy-TOPSIS; but for other alternatives ranking order differs. A comparative analysis has also been made in view of working principles of FMLMCDM, Fuzzy-TOPSIS as well as Fuzzy-MOORA. Originality/value Application feasibility of FMLMCDM approach has been verified in comparison with Fuzzy-TOPSIS and Fuzzy-MOORA in the context of agile supplier selection.

UTILIZATION OF FUZZY CONSTRAINTS TO BUILD APPLICATIONS TO SUPPORT A CONCURRENT ENGINEERING ENVIRONMENT IN THE PROCESS OF DESIGN AND MANUFACTURING

This paper proposes an integration between Conceptual Design, Manufacturing, and supply chain management. To understand new necessities we aim to integrate the decision at the early stage on developing a product. Production and logistics are the main decision on the cost and quality. The risk can not consider a low cost solution. application. In the beginning of the ideias the set of values does not include a risk for the project and if is able to do it or not. In this case it basically setting a data-model thought what is big, small, high quality, expensive, and others values, with the real manufacturing and data as fuzzy numbers. A solution will not consider a a low cost supplier that delivery with delay or a high cost production that have a high quality. Due the lack of good decision our project have been more expensive and lower quality, with this aplication we can consider a good solution in side of the best solution. Since was a research the implemetation still need to be implemented.

A historical overview of enhanced bus services in Australian cities: What has been tried, what has worked?

Enhanced bus services that aim to attract potential car users by offering qualities of services more closely aligned with those offered by the private car tend to emphasise frequency, connectivity, speed and travel time reliability. “Full” Bus Rapid Transit (BRT) is one end of the spectrum of such services that requires substantial investment in dedicated infrastructure to provide fast services but examples of enhanced services that do not require such infrastructure are more common in Australia and Europe than full BRT. This paper uses historical evidence to provide an overview of the development of these services in Australia and documents the existing evidence for the success of these initiatives taking into account the trade-offs that naturally occur as a result of the inherent constraints of network design with limited financial resources. This paper uses the concept of the passenger supply chain to describe which service attributes were targeted by the implementation of the enhanced service. It adds to the bus service literature by looking at aspects of quality of service rather than how the vehicles traverse the physical infrastructure.

Coordinating a Semi-Centralized Global Production Network Through Different Levels of Headquarters Involvement

Motivated by our experience with a global company, we propose and study the concept of a semi-centralized supply chain and analyze its coordination issues. We focus on a supply chain consisting of a home plant and a foreign branch, both of which are under the same parent company but have considerable autonomy. The role of the home plant is to provide a key component to the foreign branch with guaranteed service (required by the headquarters). Because of a high fixed order cost, the branch orders the component rather infrequently, causing high expediting costs at the home plant. Our purpose is to help the headquarters to improve the supply chain efficiency. We show that under certain conditions, the headquarters can coordinate the supply chain by setting an upper bound on the expediting frequency. If these conditions fail to hold, a simple fixed cost sharing contract coordinates the supply chain. When centralized control is too costly or infeasible, the headquarters may delegate the contract design rights to the subunits. If the home plant receives the rights, the supply chain performance can be significantly improved (sometimes to near optimality). These results provide guidance to the headquarters on whether, when, and to whom to delegate the coordination initiatives.

Closed-loop Inventory Routing Problem for returnable transport items

Increasing concerns on supply chain sustainability have given birth to the concept of closed-loop supply chain. Closed-loop supply chains include the return processes besides forward flows to recover the value from the customers or end-users. Vendor Managed Inventory (VMI) systems ensure collaborative relationships between a vendor and a set of customers. In such systems, the vendor takes on the responsibility of product deliveries and inventory management at customers. Product deliveries also include reverse flows of returnable transport items. The execution of the VMI policy requires vendor to deal with a Closed-loop Inventory Routing Problem (CIRP) consisting of its own forward and backward routing decisions, and inventory decisions of customers. In CIRP literature, traditional assumptions of disregarding reverse logistic operations, knowing beforehand distribution costs between nodes and customers demand, and managing single product restrict the usage of the proposed models in current food logistics systems. From this point of view, the aim of this research is to enhance the traditional models for the CIRP to make them more useful for the decision makers in closed-loop supply chains. Therefore, we propose a probabilistic mixed-integer linear programming model for the CIRP that accounts for forward and reverse logistics operations, explicit fuel consumption, demand uncertainty and multiple products. A case study on the distribution operations of a soft drink company shows the applicability of the model to a real-life problem. The results suggest that the proposed model can achieve significant savings in total cost and thus offers better support to decision makers.

Value Network Design for Innovations: Developing Alternative Value Network Drafts

The well-known concepts of value or supply chains do not do justice to describing how value is created in today’s complex networks. Whereas traditional value chains have been characterized by strict upstream and downstream relationships, organizations nowadays interact as networked intermediaries (Porter, 1980; Yassine & Braha, 2003). These networks not only consist of companies; any player such as a research institute can partake in the process of value creation (Fjeldstad & Ketels, 2006).

Integrating Supply Chain and Production Chain: a Genesis in the Ethanol Industry

Although frequently used interchangeably, the concepts of supply chain and production chain are considered in this study as two distinct and complementary theoretical frameworks for the conception of a data-mapping model titled SCMap – Supply Chain Map. The model’s objective is to identify and assess real chains of companies and products. An application in the agribusiness sector, starting with a specific sugarcane processing plant and the biofuel ethanol is performed. The SCMap establishes a structured and integrated manner of linking products and companies, considering three different categories of relationships: (1) between companies – supply chain approach; (2) between products – production chain approach, and; (3) between companies and products – regarding commercial practices in the corporate environment. Grounded on Graph Theory and Social Network Analysis – SNA, the software UCINET and NetDraw application are used to draw the maps and quantitatively assess the centrality of each company and product relative to the whole chain.

Investigating current paradigms in supply chain risk management – a bibliometric study

Purpose– The purpose of this paper is to analyse the intellectual structure and research fronts of discipline of supply chain risk management (SCRM), in order to identify the knowledge groups in the research area to date, as well as to reveal any relationships between these subfields and the central influential trends.Design/methodology/approach– By means of a bibliometric study, the 32 most co-cited articles on SCRM published in 16 top business-related academic journals are analysed using multivariate statistical techniques, i.e. multi-dimensional scaling, cluster analysis and correspondence factor analysis.Findings– The results demonstrate a clearly identifiable structure as a result of the performed co-citation analysis. The conducted cluster analysis and factor bring forward that the research field is arranged in five different areas of interest: explaining supply chain (SC) risk phenomena, concepts, frameworks and insights of SCRM; modelling risks for SCs; inventory risks affecting supply efficiency; SC and product design methods; and SC risk mitigating strategies.Originality/value– Overall, the intellectual structure of SCRM is first examined through a bibliometric approach using quantitative techniques – for improved understanding of its origins, and to identify the state of the science – and to offer suggestions for future studies that could cover current gaps. This study represents the potential to advance the SCRM literature landscape.
