Cross-country and inter-temporal analysis of Supply Chain Integration (SCI): China, Hungary and the Netherlands - changes in SCI from 1996 to 2008

Using plant level data from a global survey with multiple time frames, one begun in the late 1990s, this paper introduces measures of supply chain integration and discusses the dynamic relationship between the level of integration and a set of internal and external performance measurements. Specifically, data from Hungary, The Netherlands and The People’s Republic of China are used in the analyses. The time frames considered range from the late 1990s till 2009, encompassing major changes and transitions. Our results seem to indicate that SCI has an underlying structure of four sets of indicators, namely: (1) delivery frequency from the supplier or to the customer; (2) sharing internal processes with suppliers; (3) sharing internal processes with buyers and (4) joint facility location with partners. The differences between groups in terms of several performance measures proved to be small, being mostly statistically insignificant - but looking at the ANOVA table we can conclude that in this sample of companies those having joint location with their partners seem to outperform others.

Domináns vállalat versenyképességének hatása az ellátási láncban (Effects of competitiveness of the dominant company in the supply chain)

Beszállító, gyártó és vevő vállalatok alkotnak egy ellátási láncot. Optimális esetben a vállalatok integrált rendszerben működnek, az együttműködés bizal mi alapon nyugszik, így a közös stratégiai döntések révén versenyképes lesz a lánc. Az ellátási láncban lehet egy kulcsfontosságú vállalat, amelyik domináns hatalmi pozícióval rendelkezik. A kutatás célja, hogy feltárja a hatalommal rendelkező vállalat szerepét a partnercégek és az ellátási lánc versenyképességének alakulásában. A szakirodalom alapján a hipotézis feltételezi, hogy van kapcsolat a versenyképesség és a domináns vállalat szerepvállalása között. A szerzők elemzése primer kutatáson alapul, a kérdőív válaszait SPSS statisztikai kiértékeléssel végezték. Az eredmények azt mutatták, hogy a domináns vállalat versenyképességétől valóban függ a partnercégek versenyképessége. Szignifikáns kapcsolat megléte bizonyítja a hipotézist. A vizsgálatok kiemelik, hogy a verseny már egy szinttel feljebb, az ellátási lánc szintjén értelmezhető: globális ellátási láncok versenyeznek egymással. _____ Supplier, producer and buyer companies make up a supply chain. In an optimal case the companies are integrated, partnership rests on trust which results in common strategic decisions leading to competitiveness. Each supply chain has a key company with dominant power position. The objective of the research is to analyse how the company with power affects competitiveness of partner firms and the supply chain as a whole. Based on theories hypothesis assumes a link between competitiveness and power position and its influence. Methodology of the analysis is based on primary research; the authors used SPSS statistical analysis to evaluate the answers of questionnaire. Findings include that partner firms’ competitiveness rely on competitiveness of the company with dominant power position. Significant connections prove that the hypothesis is true. Results show that competitiveness is being moved up to supply chain level. Global supply chains compete with each other.

A Markov chain location-allocation meta-model for hurricane relief

An emergency is a deviation from a planned course of events that endangers people, properties, or the environment. It can be described as an unexpected event that causes economic damage, destruction, and human suffering. When a disaster happens, Emergency Managers are expected to have a response plan to most likely disaster scenarios. Unlike earthquakes and terrorist attacks, a hurricane response plan can be activated ahead of time, since a hurricane is predicted at least five days before it makes landfall. This research looked into the logistics aspects of the problem, in an attempt to develop a hurricane relief distribution network model. We addressed the problem of how to efficiently and effectively deliver basic relief goods to victims of a hurricane disaster. Specifically, where to preposition State Staging Areas (SSA), which Points of Distributions (PODs) to activate, and the allocation of commodities to each POD. Previous research has addressed several of these issues, but not with the incorporation of the random behavior of the hurricane's intensity and path. This research presents a stochastic meta-model that deals with the location of SSAs and the allocation of commodities. The novelty of the model is that it treats the strength and path of the hurricane as stochastic processes, and models them as Discrete Markov Chains. The demand is also treated as stochastic parameter because it depends on the stochastic behavior of the hurricane. However, for the meta-model, the demand is an input that is determined using Hazards United States (HAZUS), a software developed by the Federal Emergency Management Agency (FEMA) that estimates losses due to hurricanes and floods. A solution heuristic has been developed based on simulated annealing. Since the meta-model is a multi-objective problem, the heuristic is a multi-objective simulated annealing (MOSA), in which the initial solution and the cooling rate were determined via a Design of Experiments. The experiment showed that the initial temperature (T0) is irrelevant, but temperature reduction (δ) must be very gradual. Assessment of the meta-model indicates that the Markov Chains performed as well or better than forecasts made by the National Hurricane Center (NHC). Tests of the MOSA showed that it provides solutions in an efficient manner. Thus, an illustrative example shows that the meta-model is practical.

Managing supply chain knowledge-based linkages for improving operational performance

Purpose: This paper aims to explore the role of internal and external knowledgebased linkages across the supply chain in achieving better operational performance. It investigates how knowledge is accumulated, shared, and applied to create organization-specific knowledge resources that increase and sustain the organization's competitive advantage. Design/methodology/approach: This paper uses a single case study with multiple, embedded units of analysis, and the social network analysis (SNA) to demonstrate the impact of internal and external knowledge-based linkages across multiple tiers in the supply chain on the organizational operational performance. The focal company of the case study is an Italian manufacturer supplying rubber components to European automotive enterprises. Findings: With the aid of the SNA, the internal knowledge-based linkages can be mapped and visualized. We found that the most central nodes having the most connections with other nodes in the linkages are the most crucial members in terms of knowledge exploration and exploitation within the organization. We also revealed that the effective management of external knowledge-based linkages, such as buyer company, competitors, university, suppliers, and subcontractors, can help improve the operational performance. Research limitations/implications: First, our hypothesis was tested on a single case. The analysis of multiple case studies using SNA would provide a deeper understanding of the relationship between the knowledge-based linkages at all levels of the supply chain and the integration of knowledge. Second, the static nature of knowledge flows was studied in this research. Future research could also consider ongoing monitoring of dynamic linkages and the dynamic characteristic of knowledge flows. Originality/value: To the best of our knowledge, the phrase 'knowledge-based linkages' has not been used in the literature and there is lack of investigation on the relationship between the management of internal and external knowledge-based linkages and the operational performance. To bridge the knowledge gap, this paper will show the importance of understanding the composition and characteristics of knowledge-based linkages and their knowledge nodes. In addition, this paper will show that effective management of knowledge-based linkages leads to the creation of new knowledge and improves organizations' operational performance.

Implementation of supply chain management theory in practice:a questionnaire survey in the United Kingdom

Purpose: The purpose of the research described in this paper is to disentangle the rhetoric from the reality in relation to supply chain management (SCM) adoption in practice. There is significant evidence of a divergence between theory and practice in the field of SCM. Research Approach: The authors’ review of the extant SCM literature highlighted a lack of replication studies in SCM, leading to the concept of refined replication being developed. The authors conducted a refined replication of the work of Sweeney et al. (2015) where a new SCM definitional construct – the Four Fundamentals – was proposed. The work presented in this article refines the previous study but adopts the same three-phase approach: focussed interviews, a questionnaire survey, and focus groups. This article covers the second phase of the refined replication study and describes an integrated research design of a questionnaire research to be undertaken in Britain. Findings and Originality: The article presents an integrated research design of a questionnaire research with emphases on the refined replication of previous work of Sweeney et al. (2015) carried out in Ireland and adapting it to the British context. Research Impact: The authors introduce the concept of refined replication in SCM research. This allows previous research to be built upon in order to test understanding of SCM theory and its practical implementation - based on the Four Fundamentals construct - among SCM professionals in Britain. Practical Impact: The article presents the integrated research design of a questionnaire research that may be used in similar studies.

Novel Formulation and Efficient Solution Strategy for Strategic Optimization of an Industrial Chemical Supply Chain Under Demand Uncertainty

This paper is concerned with strategic optimization of a typical industrial chemical supply chain, which involves a material purchase and transportation network, several manufacturing plants with on-site material and product inventories, a product transportation network and several regional markets. In order to address large uncertainties in customer demands at the different regional markets, a novel robust scenario formulation, which has been developed by the authors recently, is tailored and applied for the strategic optimization. Case study results show that the robust scenario formulation works well for this real industrial supply chain system, and it outperforms the deterministic formulation and the classical scenario-based stochastic programming formulation by generating better expected economic performance and solutions that are guaranteed to be feasible for all uncertainty realizations. The robust scenario problem exhibits a decomposable structure that can be taken advantage of by Benders decomposition for efficient solution, so the application of Benders decomposition to the solution of the strategic optimization is also discussed. The case study results show that Benders decomposition can reduce the solution time by almost an order of magnitude when the number of scenarios in the problem is large.

Point-and-shoot: rapid quantitative detection methods for on-site food fraud analysis – moving out of the laboratory and into the food supply chain

Major food adulteration and contamination events occur with alarming regularity and are known to be episodic, with the question being not if but when another large-scale food safety/integrity incident will occur. Indeed, the challenges of maintaining food security are now internationally recognised. The ever increasing scale and complexity of food supply networks can lead to them becoming significantly more vulnerable to fraud and contamination, and potentially dysfunctional. This can make the task of deciding which analytical methods are more suitable to collect and analyse (bio)chemical data within complex food supply chains, at targeted points of vulnerability, that much more challenging. It is evident that those working within and associated with the food industry are seeking rapid, user-friendly methods to detect food fraud and contamination, and rapid/high-throughput screening methods for the analysis of food in general. In addition to being robust and reproducible, these methods should be portable and ideally handheld and/or remote sensor devices, that can be taken to or be positioned on/at-line at points of vulnerability along complex food supply networks and require a minimum amount of background training to acquire information rich data rapidly (ergo point-and-shoot). Here we briefly discuss a range of spectrometry and spectroscopy based approaches, many of which are commercially available, as well as other methods currently under development. We discuss a future perspective of how this range of detection methods in the growing sensor portfolio, along with developments in computational and information sciences such as predictive computing and the Internet of Things, will together form systems- and technology-based approaches that significantly reduce the areas of vulnerability to food crime within food supply chains. As food fraud is a problem of systems and therefore requires systems level solutions and thinking.

Sostenibilità della Supply Chain e indici di misurazione delle performance

Il presente elaborato si propone di analizzare la tematica della sostenibilità nella gestione della Supply Chain, con particolare attenzione alla misurazione delle performance attraverso indicatori KPI e modelli multidimensionali. Nella prima sezione, dopo un’introduzione sul tema dello sviluppo sostenibile, si offre una descrizione dello scenario attuale e degli approcci alla sostenibilità, evidenziandone i principi guida e le sfide future, mentre in seguito vengono analizzate le pressioni esercitate dagli stakeholder per l’implementazione di pratiche sostenibili. La seconda porzione dell’elaborato è incentrata sull’introduzione della sostenibilità nel Supply Chain Management, caratterizzandone l’evoluzione dalla tradizionale gestione della catena di fornitura e mettendone in luce opportunità e barriere. Successivamente, la terza parte si propone di entrare nel dettaglio in merito alle pratiche adottabili nella filiera finalizzate all’implementazione di un management sostenibile, proponendo un modello concettuale per l’analisi delle varie attività, dalla progettazione di prodotto fino alla logistica inversa. Un’ulteriore tematica approfondita è rappresentata dall’impatto di queste pratiche sostenibili sulle performance economiche aziendali, proponendo diversi approcci. Nell’ultima sezione dell’elaborato il focus è incentrato sulla misurazione delle performance di sostenibilità, dove ne vengono indagate opportunità e difficoltà, proponendo in seguito un modello teorico. Contestualmente vengono quindi esposti diversi KPI e modelli multidimensionali, i quali, con modalità e prospettive diverse, contribuiscono alla misurazione delle prestazioni di sostenibilità: in particolare viene fatto riferimento agli indici caratteristici del GRI e all’utilizzo combinato della balanced scorecard e dell’analytic hierarchy process.

Relaciones y capacidades interorganizativas: un enfoque de Supply Chain Management (SCM) en red

El presente trabajo mide, en un contexto colaborativo, un conjunto de mecanismos relacionales interconectados y su incidencia en el performance organizacional. Apoyado en la Visión Relacional (Dyer y Singh, 1998), el trabajo integra mecanismos de las capacidades relacionales y capacidades competitivas en el concepto denominado ¿capacidades interorganizativas¿. Las capacidades interorganizativas se componen de la ¿confianza¿ y los mecanismos ¿combinar recursos complementarios¿, ¿invertir en activos específicos¿, ¿compartir información¿ y ¿solucionar problemas conjuntamente¿. La medición tiene lugar en la Industria Alimentaria (IA) española en un contexto de Supply Chain Management1 en red. Además de mejorar el conocimiento sobre las relaciones interorganizativas, el trabajo también realiza una revisión teórica sobre el sector agroalimentario en general y la IA en particular. Los resultados permiten confirmar, con excepciones, el constructo teórico de las ¿capacidades interorganizativas en un contexto de Supply Chain Management en red¿. Otros resultados obtenidos son los altos niveles de confianza en las relaciones entre socios y una industria que, pese al entorno competitivo y complejo actual, presenta niveles competitivos en términos de flexibilidad, respuesta, calidad y eficiencia. De igual modo, la investigación descubre la implantación de la capacidad de las empresas de la industria para gestionar el conocimiento. En este contexto, los resultados parecen indicar una correcta integración de la cadena de suministros de la IA que confirman la efectiva aplicación de la Supply Chain Management. Otras conclusiones obtenidas son la dependencia que ha tenido y tiene la industria alimentaria española de la distribución, intensificada en parte por la expansión de las marcas del distribuidor (MDDs).

From the farm to the fork: fungal occupational exposure in the swine meat supply chain

Feed production, swine and slaughterhouses were already reported as occupational environments with high fungal contamination. This condition can ultimately lead to the development of several health conditions. This study aimed to characterize the occupational exposure to fungal burden in three different settings: swine feed unit, swine units and slaughterhouse.

Green supply chain management practices and firm performance: evidence from Finland

In order to address the increasing stakeholder requirements for environmentally sustainable products and processes, firms often need the participation of their supply chain partners. Green supply chain management has emerged as a set of managerial practices that integrate environmental issues into supply chain management. If implemented successfully, green supply chain management can be a way to achieve competitive advantage while enhancing the environmental sustainability of the firm. The overall purpose of this dissertation is to contribute to the discussion on green supply chain management practices from the perspective of their drivers and performance implications. The theoretical background arises from the literature on competitive strategy, firm performance and green supply chain management. The research questions are addressed by analysing firm-level data from manufacturing, trading and logistics firms operating in Finland. The empirical data comes from two consecutive Finland State of Logistics surveys in 2012 and 2014, combined with financial reporting data from external databases. The data is analysed with multiple statistical methods. First, the thesis contributes to the discussion of the drivers of GSCM practices. To enhance the understanding of the relationship between competitive strategy and GSCM practices, a conceptual tool to describe generic competitive strategy approaches was developed. The findings suggest that firms pursuing marketing differentiation are more likely to be able to compete by having only small environmental effects and by adopting a more advanced form of external green supply chain management, such as a combination of strong environmental collaboration and the increased environmental monitoring of suppliers. Furthermore, customer requirements for environmental sustainability are found to be an important driver in the implementation of internal GSCM practices. Firms can respond to this customer pressure by passing environmental requirements on to their suppliers, either through environmental collaboration or environmental monitoring. Second, this thesis adds value to the existing literature on the effects of green supply chain management practices on firm performance. The thesis provides support for the idea that there is a positive relationship between GSCM practices and firm performance and enhances the understanding of how different types of GSCM practices are related to 1) financial, 2) operational and 3) environmental performance in manufacturing and logistics. The empirical results suggest that while internal GSCM practices have the strongest effect on environmentalperformance, environmental collaboration with customers seems to be the most effective way to improve financial performance. In terms of operational performance, the findings were more mixed, suggesting that the operational performance of firms is more likely to be affected by firm characteristics than by the choices they make regarding their environmental collaboration. This thesis is also one of the first attempts to empirically analyse the relationship between GSCM practices and performance among logistics service providers. The findings also have managerial relevance. Management, especially in manufacturing and logistics industries, may benefit by gaining knowledge about which types of GSCM practice could provide the largest benefits in terms of different performance dimensions. This thesis also has implications for policy-makers and regulators regarding how to promote environmentally friendly activities among 1) manufacturing; 2) trading; and 3) logistics firms.

INTERACTIVE EFFECT OF FIXED TIME ORDER STRATEGIES WITHIN A SUPPLY CHAIN ON ACTUAL IN-STOCK PROBABILITIES

This report mainly deals with the interactive effect of different in-stock probabilities used by every individual in a supply chain. Based on a simulation for 10,000 weeks, the effects of varying in-stock probabilities are observed. Based on these observations, an individual in a supply chain can take counter measures in order to avoid stock out chances hence maintaining profits.

Analisi della Supply Chain e mappatura degli acquisti. Caso aziendale: Termotecnica Industriale S.r.l.

Il Supply Chain Management è una rete di strutture che producono materie prime e le trasformano in prodotti finiti da consegnare ai clienti. Per gestire in maniera efficace l’impresa, l’intera struttura della catena di approvvigionamento deve seguire il flusso aziendale correttamente, in modo da non creare rallentamenti nella fornitura e causare problemi al soddisfacimento dei bisogni del cliente. Questo elaborato analizza tutte le componenti che influiscono sul successo di una supply chain, in particolare la funzione strategica degli acquisti, evidenziandone le principali problematiche che si possono riscontrare e le soluzioni che invece si possono applicare. Gli acquisti, che nascono dalla richiesta di un bisogno da soddisfare, sono da considerarsi un vantaggio competitivo e di redditività per un’azienda, in quanto incidono direttamente sul fatturato totale, motivo per cui sono stati oggetto dello studio. L’acquisto deve rispecchiare le specifiche tecniche e funzionali richieste, al fine di soddisfare i bisogni del cliente. Analizzando tale reparto presso l’azienda Termotecnica Industriale S.r.l., una Piccola Media Impresa (PMI) che si occupa di progettazione, fabbricazione ed installazione di caldaie industriali e generatori di vapore a recupero di calore, si è ricercato un nuovo modello di approvvigionamento da seguire. L’obiettivo di questa analisi è di sviluppare una strategia aziendale che gestisca in maniera corretta la catena di fornitura, ottenendo migliori condizioni contrattuali ed evitare problemi come gli acquisti a collo di bottiglia. E’ stato necessario, individuare una nuova metodologia che aiutasse i buyer a instaurare il giusto rapporto col fornitore selezionato, in funzione all’acquisto che si sta per compiere. Infatti per ogni tipologia di approvvigionamento ci sono approcci differenti da utilizzare con i fornitori per ottenere delle agevolazioni rispetto a quanto offerto in precedenza dello stesso.
