Simulation-Based Optimisation Model For The Lean Assessment In Sme: A Case Study, Amr Arisha, Amr Mahfouz, John Shea Dec 2011

Simulation-Based Optimisation Model For The Lean Assessment In Sme: A Case Study, Amr Arisha, Amr Mahfouz, John Shea

Conference papers

Due to their space limitation and small production scale, small and medium enterprises (SME) are vulner-able to rapid changes. Lean principles are considered as effective improvement approach to eliminate sys-tem’s waste and inefficiencies. Although much of the academic materials have addressed the lean practic-es into large, global companies, they can still be adjusted to SMEs. Risks are usually associated with lean implementation process due to the drastic required changes in business policies and operations. Simulation can be successfully used to predict the impact of the proposed changes ahead of the implementation which helps to mitigate risks. Integrating simulation with optimization …

Supply Chain Management: Scm Key To Competitiveness, Edward Sweeney

Practitioner Journals

Any meaningful attempt to eliminate waste and improve cost competitiveness in the Irish packaging sector must have a strong focus on how the supply chain is designed and managed.


Towards A Unified Definition Of Supply Chain Management, Edward Sweeney Jul 2011

Towards A Unified Definition Of Supply Chain Management, Edward Sweeney

Articles

A wide range of definitions of supply chain management (SCM) have been developed over the last three decades. The philosophy of SCM is based firmly on a recognition that it is only by working in a more integrated manner that competitive advantage can be maximised. However, for this to become a reality the development of common definitions and understandings between supply chain partners is a critical success factor. The corollary of this is that a lack of definitional consistency and a common understanding is an inhibitor to the successful adoption of SCM thinking in practice. This paper reviews a number …


Optimal Production Planning For A Multi-Product Closed Loop System With Uncertain Demand And Return, Jianmai Shi, Guoqing Zhang, Jichang Sha Mar 2011

Optimal Production Planning For A Multi-Product Closed Loop System With Uncertain Demand And Return, Jianmai Shi, Guoqing Zhang, Jichang Sha

Mechanical, Automotive & Materials Engineering Publications

We study the production planning problem for a multi-product closed loop system, in which the manufacturer has two channels for supplying products: producing brand-new products and remanufacturing returns into as-new ones. In the remanufacturing process, used products are bought back and remanufactured into as-new products which are sold together with the brand-new ones. The demands for all the products are uncertain, and their returns are uncertain and price-sensitive. The problem is to maximize the manufacturer's expected profit by jointly determining the production quantities of brand-new products, the quantities of remanufactured products and the acquisition prices of the used products, subject …


Toward A Technology Management Core: Defining What The Technology Manager Needs To Know, Mark Doggett, Pam Mcgee, Sophia Scott Jan 2011

Toward A Technology Management Core: Defining What The Technology Manager Needs To Know, Mark Doggett, Pam Mcgee, Sophia Scott

With the increasing demands on organizations to do “more with less,” and produce acceptable market results, productivity and performance standards continually raise the expectations on competitive success. To meet these expectations, organizations should create learning opportunities that combine the application of technical management skills along with the softer skills involved in people management. Technical managers with little training or past experience with nontechnical skills often perform poorly in technical management positions (Kroecker, 2007). Because this generation lives in a highly technical environment, managers need to be proficient in dealing with knowledge workers and systems; therefore, there is a growing emphasis …


Virtual Ed: Utilisation Of A Discrete Event Simulation-Based Framework In Identifying "Real-Time’ Strategies To Improve Patient Experience Times In An Emergency Department, Waleed Abo Hamad, John Mcinerney, Amr Arisha Jan 2011

Virtual Ed: Utilisation Of A Discrete Event Simulation-Based Framework In Identifying "Real-Time’ Strategies To Improve Patient Experience Times In An Emergency Department, Waleed Abo Hamad, John Mcinerney, Amr Arisha

Articles

Objectives and Backgrounds Emergency Department (ED) overcrowding and associated excessive Patient Experience Times (PETs) have proven deleterious impacts on patient mortality, morbidity and overall length of hospital stay. Health systems constantly seek cost-effective organisational strategies to reduce ED crowding and improve patient outcomes, but complex change implementation is constrained by the necessity of maintaining concurrent safe patient-care. Computer modelling in a “virtual reality” has been successfully utilised in industries outside medicine, in providing innovative “real-time” solutions to outdated practices. Therefore a bespoke “Virtual ED” computer model, based on a Discrete Event Simulation (DES) -Based Framework was constructed to determine the …


Introduction: Advances In E-Business Engineering, Ling Li Jan 2011

Introduction: Advances In E-Business Engineering, Ling Li

Information Technology & Decision Sciences Faculty Publications

(First paragraph) E-business is more than just e-commerce. It is one of the most challenging areas for industry and research communities. E-business has evolved from business-to-business, business-to-customer, customer-to-business, customer-to-customer, and business-to-government systems to the integrated and collaborative business services among various information systems and e-marketplaces. In this evolving process, integrated e-business systems and their related supporting platforms have to be rapidly designed and developed in order to meet different requirements. A variety of e-business engineering paradigms and technologies have been developed to tackle these challenges. There are many research issues needed to be addressed. These issues include heterogeneous services integration, …
