A Review of Knowledge Management in the Public Sector: A Taxonomy
(2015)
Mc Evoy, Paul J; Arisha, Amr; Ragab, Mohamed
Abstract:
Purpose – Public organisations today face management challenges to cope with current markets in what’s known as a knowledge era. They primarily face adaptive challenges. Changes in communities, markets, business behaviour, competition, and most importantly technology around the globe are forcing all organisations to clarify their strengths, develop knowledge strategies, and learn new ways of managing their human capital. Governmental organisations also exhibit tendencies towards unusual and bureaucratic cultures mired in hierarchical structures, which create peculiar challenges that confront Knowledge Management (KM) efforts within the public sector. As public firms attempt to effectively manage their knowledge, organisational culture and structure have been identified as crucial defining factors in the successful assimilation and dissemination of knowledge. Often the toughest task for managers in effecting change in the public sector is mobilising people throughout the organisation...

A Simulation Model to Characterize Photolithography Process of a Semiconductor Wafer Fabrication
(2003)
Arisha, Amr; Young, Paul; El Baradie, Mohie
Abstract:
The pressures on semiconductor manufacturers due to cost considerations, rapid growth of process technology, quality constraints, feature size reduction, and increasingly complex devices are increasing requiring ever higher efficiency from the manufacturing facilities. The complexity of manufacturing high capacity semiconductor devices means that it is impossible to analyze the process control parameters and the production configurations using traditional analytical models. There is, therefore, an increasing need for effective models of each manufacturing process, characterising and analyzing the process in detail, allowing the effect of changes in the production environment on the process to be predicted. The photolithography process is one of the most complex processes in a semiconductor manufacturing environment. Using state-of-the-art computer simulation and a structured modelling methodology a generic model of photolithography flexible manufacturing cells has been developed and...

A Simulation-Based Decision Support System to Model Complex Demand Driven Heathcare Facilities
(2012)
Arisha, Amr; Thorwarth, Michael
Abstract:
Simulating healthcare processes is a sophisticated endeavor. Treatment processes and patient arrival patterns differ significantly in their statistical attributes and implicate a high degree of variability. In addition, there are several types of interconnected processes of medical staff involved that accompany a patient’s journey through the healthcare facility. Replicating this behavior with process flow models in a discrete event simulation model is highly complex and therefore difficult to create while maintaining a high degree of precision. A framework is thus introduced which delivers an algorithm that allows to implement Multiple Participant Pathway Modeling (MPPM) under the consideration of Flexible Resource Allocation (FRA). This framework is applied on an Irish Emergency Department (ED), the outcome of which is presented here. Results show that scenarios can be investigated which impact several different process flows with a high precision. This provides a solid base for b...

A System Dynamics View of the Acute Bed Blockage Problem in the Irish Healthcare System
(2015)
Abo-Hamad, Waleed; Rashwan, Wael; Arisha, Amr
Abstract:
Global population ageing is creating immense pressures on hospitals and other healthcare services, compromising their abilities to meet the growing demand from elderly patients. Current demand–supply gaps result in prolonged waiting times in emergency departments (EDs), and several studies have focused on improving ED performance. However, the overcrowding in EDs generally stems from delayed patient flows to inpatient wards – which are congested with inpatients waiting for beds in post-acute facilities. This problem of bed blocking in acute hospitals causes substantial cost burdens on hospitals. This study presents a system dynamics methodology to model the dynamic flow of elderly patients in the Irish healthcare system aimed at gaining a better understanding of the dynamic complexity caused by the system's various parameters. The model evaluates the stock and flow interventions that Irish healthcare executives have proposed to address the problem of delayed discharges, and ult...

An Analytical Representation of Flexible Resource Allocation in Hospitals
(2015)
Thorwarth, Michael; Rashwan, Wael; Arisha, Amr
Abstract:
Non-linear processes within complex systems are difficult to predict. Using discrete event simulation (DES) models can be helpful for presenting the uncertainty level embedded within these processes. However, the interpretations of the resulting outcomes can be challenging to analyze. This is evident when experimenting with simulation models, and therefore requires the adaptation of existing models. Introducing cyclic entities such as interconnected resources to the simulation model adds a new level of complexity to the model. In practical cases, decision makers often demand a model that enables them to make quick decisions with less complexity involved. However, these individuals still want to be assured of a high degree of accuracy in the results. This article demonstrates how an analytical representation of complex DES models can be developed in order to facilitate prompt yet effective solutions for decision makers. This analytical representation provides a brief overview of the ...

An Empirical Estimation of Statistical Inferences for System Dynamics Model Parameters
(2014)
Mesabbah, Mohammed; Rashwan, Wael; Arisha, Amr
Abstract:
For system dynamics simulation (SD) models, an estimation of statistical distributions for uncertain parameters is crucial. These distributions could be used for testing models sensitivity, quality of policies, and/or estimating confidence intervals for these parameters. Assumptions related to normality, independence and constant variation are often misapplied in dynamic simulation. Bootstrapping holds a considerable theoretical advantage when used with non-Gaussian data for estimating empirical distributions for unknown parameters. Although it is a widely acceptable approach, it has had only limited use in system dynamics applications. This paper introduces an application of Direct Residual Bootstrapping (DRBS) for statistical inference in system dynamic model. DRBS has been applied successfully to ‘The Irish Elderly Patient Delayed Discharge’ dynamic model to estimate empirical distribution for some unknown parameters with a minimal computation effort.

Abstract:
Hospitals are witnessing an inexorable growth in emergency admissions, which results in overcrowding and a poorer patient experience. The Acute Medicine Program (AMP) is one of the programs developed by the Irish health authority aimed at improving patient experience. To review the AMP intervention, this study applies a model that integrates three analytical approaches: simulation, multivariate factor analysis and multi-objective optimization. The simulation identified 14 different factors affecting five responses that were used to develop a Design of Experiments (DoE). Multivariate factor analysis used the DoE to determine the factors creating ‘bottlenecks’, such as downstream resources. The multi-objective optimization model, based on the Simulated Annealing approach, is applied to support management decisions on optimizing key parameters affecting the treatment journey of patients. A Pareto set of solutions found that an increase in downstream capacity and unit staff can lead to ...

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.

Arisha, Amr; Mahfouz, Amr
Abstract:
Given the vital role of distribution units within the supply chains, this research aims to develop a comprehensive lean assessment framework that integrates Modelling and Simulation with Value Stream Mapping (VSM) and Data Envelopment Analysis (DEA) to assess the ‘leanness’ level in distribution business. The framework is applied on a distribution centre of a leading European company in the tyre manufacturing and distribution business. The framework helps decision makers to evaluate the effect of two lean distribution practices – Pull Order Replenishment and Class-Based Storage Policy – on company’s performances and is also used as a leanness Self-Assessment Tool.

An Integrative Lean Assessment Model for Distribution Centres.
(2013)
Mahfouz, Amr; Smith, Laura; Arisha, Amr
Abstract:
It is hard to benefit fully from lean manufacturing without having an efficient distribution centre. Applying lean distribution concept helps to reduce distribution centres waste while maintains customer service level high. The purpose of this study is to develop a lean assessment model that enables distribution managers to measure and improve the leanness levels of their companies. A data driven analytical approach (i.e. factor analysis) is used to assess leanness quantitatively. A lean index score is calculated to benchmark the leanness level of four distribution companies based in Ireland and UK. Results recommend that special attention should be taken on simplifying distribution network structure, establishing long term suppliers’ collaboration, managing customer demand, improving storage space utilisation, and managing distribution operations more efficiently.

Mc Manus, Paul; Mulhall, Sue; Ragab, Mohamed; Arisha, Amr
Abstract:
The sizeable increase in doctoral business research in Ireland over past decades is characterised by a diversity of research paradigms and the methods applied. To achieve research objectives, doctoral researchers should identify the methodological framework of inquiry that they will use to address and answer their research question. This involves taking a stance on divergent philosophical assertions such as ontology and epistemology, which reflect how they view the world. Researchers often proceed to select what is believed to be the best- suited research approach – either qualitative, quantitative, or a mixture between them – with their corresponding subset of data collection and analysis techniques. This paper aims to examine extant doctoral research in business over a ten-year period within the Irish academic community to ascertain prominent methodological practices, recent trends, and the philosophical underpinnings surrounding the choices made. A comprehensive typology into the...

Abstract:
Semiconductor fabrication facilities face many challenges through the many phases of their life cycle including design, build, various production ramps, and many levels of production. Confronted with global competition and rapidly changing technology and customer requirements, there is an increasing demand for rapid solution techniques to improve efficiency in manufacturing. The complexities and forces of both market and the process combine to make the use of simulation crucial at many different planning and control levels. While not a panacea for sustainable performance, simulation provides an effective vehicle for defining the path from competitive concepts to real world solutions and gives an opportunity to experiment with, and assess the impact of, production plans, aiding the management and production teams’ decisions. Integrating simulation with common approaches; Operations Research (OR) and Artificial Intelligence (AI) to solve manufacturing problems is a new trend towards h...

Abstract:
Global population aging is creating an immense pressure on healthcare facilities making them unable to cope with the growing demand for elderly healthcare services. Current demand-supply gaps result in prolonged waiting times for patients and substantial cost burdens for healthcare systems due to delayed discharges. This paper describes a project aimed at presenting modeling and simulation to address elderly care pathways within the Irish healthcare sector. The management of frail patients admitted to acute hospitals and the introduction of the new intermediate care beds are alternative interventions that healthcare executives are interested in simulating to examine their impact on the performance of the elderly care system. The developed simulation model, along with the statistical analysis, have enabled the management to assess the current system under the critical financial and performance issues. It also highlights the decision variables that significantly improve the flow of el...

Customer Management Analysis of Irish Plumbing & Heating Distribution System: A Simulation Study

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...

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...

Enabling RFID Technology in Irish Hospitals
(2009)
Ismail, Khaled; Arisha, Amr
Abstract:
Hospitals represent a significant part of healthcare systems and account for no less than 60% of the entire healthcare service in most of developed countries. Therefore, improving service in hospitals is an important element to the process of healthcare reform. Better use of resources, more consistent quality, and a higher service level are the keys to rationalise the huge expenditure in healthcare systems due to higher growth in demand. Even though massive spending has been directed towards hospital improvement in Ireland, services provided in Irish hospitals are ranked relatively low comparing to the other European countries. Growth of population, aging, European Union regulations, and demanding patients place more pressure on healthcare researchers to provide innovation solutions for Irish hospitals. In the last two decades, the use of technology had a significant impact on hospital performance in terms of responsiveness, quality, and management practices. Radio Frequency Identif...

Abstract:
Global population ageing is creating an immense pressure on hospitals to meet the growing demand for elderly healthcare services. Current demand-supply gaps results in prolonged waiting times for patients and substantial costs for hospitals due to delay in discharges. This paper uses System Dynamics (SD) methodology to map the dynamic flow of elderly patients in the Irish healthcare system. The developed system dynamic model helped decision makers to envisage the complexity resulted in the system due to the infringing parameters. Stock and flow intervention policies are proposed and evaluated subject to the projected future demographic changes. The model enables policy makers to identify potential strategic policies that will contribute significantly to overcome the delayed discharge for elderly patients. Results show acute bed occupancy can be reduced to reach 76% with a significant reduction in delayed discharge. Future work will focus on using a modified model of the developed na...

Abstract:
Scheduling of a semiconductor manufacturing facility is one of the most complex tasks encountered. Confronted with a high technology product market, semiconductor manufacturing is increasingly more dynamic and competitive in the introduction of new products in shorter time intervals. Simulation provides an effective decision support tool in scheduling of semiconductor manufacturing. Simulation model was developed as a risk assessment tool for one of the implant process area. The model examines the impact of production schedule on tool performance by testing different production scenarios. Production ramping, local buffer capacity, product sequence and product mix seem to be influential factors of the toolset performances.

Evaluation of Scheduling Strategies on the Performance of a Flexible Manufacturing Cell:a Simulation Study

Abstract:
The current trend in semiconductor manufacturing is characterized by expanding product variety, decreasing lead times from order to delivery, exacting standards of quality, and competitive prices. One possible means of achieving this is in the form of increased flexibility. Providing flexibility is typically an expensive proposition so, industrial engineers aim to provide more economic approaches to enable flexible manufacturing cells and related equipment to operate appropriately in an efficient manner. It is essential to characterize these tools in detail before the production plans are finalized. Using state-of-the-art computer simulation, a generic model of photolithography tools has been developed. The model examines the impact of changing product volumes, buffer size, product sequence and product-mix on performance criteria, e.g. throughput time. The high investment cost of flexible manufacturing cells justifies the use of computer simulation support to maintain high system pe...

Abstract:
A computational study has been developed to obtain optimal / near optimal solution for the flow shop scheduling problem with make-span minimization as the primary criterion and the minimization of either the mean completion time, total waiting time or total idle time as the secondary criterion. The objective is to determine a sequence of operations in which to process ‘n’ jobs on ‘m’ machines in same order (flow shop environment) where skipping is allowed. The Simulation approach for deterministic and stochastic flow shop scheduling has been developed. It reads and manipulates data for 500 jobs on 500 machines. Different factorial experiments present a comparative study on the performance of different dispatching rules, such as FCFS, SPT, LPT, SRPT and LRPT with respect to the objectives of minimizing makespan, mean flow time, waiting time of jobs, and idle time of machines. The proposed model is evaluated and found to be relatively more effective in finding optimal/ near optimal so...
