An Integrated Decision Support Framework For Assessing Food Supply Chain Risk Management Processes: A Food Retail Case Study
(2013)
Arisha, Amr; Crowe, John
Abstract:
Global confidence and reliability in Irish food supply chains are essential elements to overall competiveness and future growth. The complex nature of food supply chains make them vulnerable to many sources of risk, both internal and external. Integrating the SCOR11 model with system dynamics and discrete-event simulation modelling is effective decision support integration, reducing the risks decision makers have to manage daily. At GRD, using the integrated framework to assess the risks associated with lean initiatives helped management in understanding both the risk scenario, likelihood and impact factor of their decisions on operations performance measures.

An Investigation of the psychosocial impact of a compensation tribunal on women with an iatrogenic Hepatitis C infection
(2014)
Coughlan, B. M.; Sheehan, John D.; Carr, Alan; Crowe, John
Abstract:
The aim of this study was to investigate the psychosocial impact of a Compensation Tribunal in women with an iatrogenic hepatitis C virus (HCV) infection. Eighty-three women diagnosed with an iatrogenic HCV infection were recruited, 19 women were Pre-Tribunal and 64 women were post-Tribunal. Both standardised and disease specific psychological measures were used. A series of t-tests revealed no differences in psychological well-being and adjustment to HCV infection in women pre and post Compensation Tribunal. Chi-square tests revealed no association between PCR status and 1) psychological well-being and 2) experience of anger/blame in women post- Compensation Tribunal. A further series of t-tests revealed that women with high levels of anger and blame post-Compensation Tribunal perceived their future as more uncertain, experienced more pain, low self-esteem and psychological distress, viewed their ability to work as impeded and complained of increased stress preparing for their Comp...

Customer Management Analysis of Irish Plumbing & Heating Distribution System: A Simulation Study
(2010)
Arisha, Amr; Mahfouz, Amr; Crowe, John; Bennett, Finbarr
Abstract:
The sudden burst of the property bubble, coupled with current global economic conditions has resulted in a huge decrease in demand for plumbing and heating fixtures in the Irish construction industry. Moreover, inefficient supply chain management policies have imposed further pressures on companies resulting in more system bottlenecks and unnecessary costs. Inventory management is seen as a functional area that can ease such bottlenecks and in turn increase supply chain efficiency, decrease costs and increase customer satisfaction. The challenge is to predict the balance of on-hand inventory and order quantity to optimise customer satisfaction and minimise inventory cost. It is also essential that managers clearly understand the cost effect stock-outs have on different groups of customer, i.e. customer segmentation policy. Traditional inventory mathematical techniques are inadequate in investigating the influence of customer segmentation policy on performance. To investigate this fu...

Distributed Supply Chain Simulation Portal: Design and Implementation
(2011)
Arisha, Amr; Tobail, Ayman; Crowe, John
Abstract:
The emerging paradigm of eLearning is becoming increasingly in evidence across many academic disciplines acknowledging the concept that learning processes no longer support traditional teaching methods alone. It can be argued that today’s third level education students are part of a new virtual era where the blackboard has been replaced with an interactive whiteboard. To assist in the transition from traditional learning to eLearning, more interactive and virtually orientated teaching aids are needed. A simulation-based learning framework that integrates web-based simulation and a web content management hierarchy model is the key objective of this paper. Using the highly complex subject of supply chain management as a case study, the new framework allows users to examine various management strategies of real-life scenarios, encourages group work and has remote access capabilities for distance learning. Interactive learning is facilitated using the web-based simulation portal, enabli...

Increasing Value Generation Using a Hierarchical Simulation-Based SCOR Framework
(2012)
Crowe, John; Arisha, Amr
Abstract:
We are part of extraordinary times, global recession coupled with increased competition; high costs and decreasing demand have changed the dynamics of supply chain management (SCM). In response, many organizations have fast-tracked changes to corporate-level strategies to reduce costs and maintain profit margins and have not considered the long-term impact these decisions have on more operational-level SCM activities. This has resulted in a renewed focus on customer value and the economic and behavioral systems of the supply chain, or more accurately, the value chain. The Supply Chain Operations Reference (SCOR) model increases the integration organizations have within their supply chains and increases alignment between different hierarchical strategies. Simulation techniques, in particular discrete-event simulation (DES) and system dynamics (SD) are proven techniques in improving SCM corporate and operational decision making processes. This paper presents a framework that integrate...

Integrating Current State and Future State Value Stream Mapping with Discrete Event Simulation: a Lean Distribution Case Study
(2011)
Mahfouz, Amr; Crowe, John; Arisha, Amr
Abstract:
In response to global recession and increased competition, organizations have tried to become more efficient by decreasing costs and streamlining operations. To achieve this, the philosophy of lean management has gained in popularity. The main obstacle organizations face when implementing lean is deciding which activities to implement lean principals on. A well known lean practice, value stream mapping, is a very effective tool in mapping the current and future state of an organizations lean activities. Limitations in calculating variability information that describe system variations and uncertainty means more powerful analytical tools are needed. Simulation offers a more thorough analysis of a system’s data, including the examination of variability and has the ability to change certain parameters and measure key lean performance indicators. Using a tire distribution company as a case study, this paper has developed a framework that uses discrete event simulation as an integrative ...

Learning by Gaming: Supply Chain Management
(2011)
Arisha, Amr; Tobail, Ayman; Crowe, John
Abstract:
Today's third level students are of a virtual generation, where online interactive multi-player games, virtual reality and simulations are a part of everyday life, making gaming and simulation a very important catalyst in the learning process. Teaching methods have to be more innovative to help students understand the complexity of decisions within dynamic supply chain environment. Interactive simulation games have the potential to be an efficient and enjoyable means of learning. A serious interactive business game, Automobile Supply Chain Management Game (AUSUM), has been introduced in this paper. Using theories learnt in class as a knowledge base, participants have to develop effective supply chain partnership strategy to enhance their supply chain networks. Deploying the game over the web encourages student interaction and group work. Most importantly the game will enable students to fundamentally grasp the impact of strategic decisions on other parts and players of the supp...

Abstract:
High levels of complexity and uncertainty, and various sources of risks, create challenges for supply chain networks in achieving satisfactory performance, but advances in Information Technology can help supply chain decision makers predict the magnitude and impact of the risks related to their decisions. The framework proposed in this paper offers a solution that integrates intelligent-agents, simulation modelling, and optimisation. Its friendly, animated, interactive web-based interface is especially designed to engage the user in a ‘serious game’ environment. Each user plays a specific role in the supply chain network, and encounters the consequences of their decisions. The optimisation engine embedded in the framework advises users about the optimum decisions and their anticipated performance outcomes. Genetics Algorithm (GA) and Case-Based Reasoning (CBR) are used to enhance the decision quality. A high-level communication protocol has been designed, developed and implemented t...

Supply Chain Simulation: Experimentation without Pain
(2010)
Arisha, Amr; Tobail, Ayman; Crowe, John
Abstract:
Bridging the gap between theory and practice has always been a key issue for students and graduates. The magnitude and scope of subject areas that students at third level institutions have to learn in theory means that visualising them without any practical experience can be very difficult. Understanding the complexity of supply chain networks and how to manage them create a considerable level of difficulty for students and professionals. Theories and applications included in supply chain management subjects are the key to empathise the real challenges. Nevertheless, teaching these theories needs substantial efforts and new innovative approaches to deliver the concepts and assure successful transfer of the learning outcomes. To complicate things more, the levels of uncertainty and risk within an entire supply chain are still not fully recognised or understood even by industry professionals. Research studies showed the need for more transparency and collaborative approaches to take p...

Abstract:
Recently, the application of lean thinking in healthcare has grown significantly in response to rising demand caused by population growth, ageing and high expectations of service quality. However, insufficient justifications and lack of quantifiable evidence are the main obstacles to convince healthcare executives to adopt lean. Therefore, this paper presents a methodology that integrates lean tools with simulation to enhance the quality of patient care in healthcare facilities. This enables healthcare organisations to dedicate more time and effort to patient care without extra cost to the organisation or to the patient. Value stream mapping is used to identify value-added and non-value-added activities.. Then, a comprehensive simulation model is developed to account for the variability and complexity of healthcare processes and to assess the gains of proposed improvement strategies. An extensive analysis of results is provided and presented to managers to illustrate the potential b...

UNDERSTANDING THE DYNAMIC BEHAVIOUR OF THREE ECHELON RETAIL SUPPLY CHAIN DISRUPTIONS
(2015)
Crowe, John; Mesabbah, Mohammed; Arisha, Amr
Abstract:
It is often taken for granted that the right products will be available to buy in retail outlets 7 days a week, 52 weeks a year. Challenges in achieving this continued on-shelf availability range from recession hit demand patterns to cost reduction driven strategies. Irish government initiatives to brand the country as a sustainable, reliable provider of food retail supply chains has resulted in increased importance on decision maker accuracy. The vulnerability of retail supply chain’s (RSC) to disruption is another catalyst in the complexity of the decision making process and a more robust understanding of disruption behavior is needed. The aim of this paper is to illustrate the advantages of integrating balanced scorecard system thinking to system dynamic modeling of an extended retail supply chain. With this approach, decision makers can gain a better understanding of disruptions within their own organization and the partnerswithin their extended RSC.

Abstract:
This is an era marked by rapid technology development in all different educational arenas. Alongside this growing demand of technology, learning process is getting new forms and hence traditional teaching approaches tend to struggle and lack the requisite qualities to meet new generation expectations. In third level education, this problem is increasing in magnitude and new dimensions, especially when it comes to teaching difficult subjects such as supply chain management. Understanding the complexity of supply chain networks and how to manage them create a considerable level of difficulty for students and professionals. Collaboration between supply chain members is now recognised as an important strategic factor in creating a solution to the complexity of the supply chain system. New technologies are beginning to bring a huge transformation into teaching delivery methods. This paper presents an integrated web-based simulation framework that supports learning supply chain concepts a...
