Performance Improvements through Implementation of Lean Practices: A Study of the U.K. Red Meat Industry

'Lean' is an established industrial paradigm with proven track record in various sectors of the industry (Womack & Jones, 1996). World-class Companies such as Toyota (second biggest global car manufacturer), Porsche (most profitable global OEM), Boeing (largest global aerospace business) and Tesco (third largest global retailer) have adopted Lean at the corporate level. This paper reports on the introduction of 'Lean Thinking' to a new sector - the 'Red Meat Industry' (Food Chain Centre, 2004). This contribution highlights the benefits of lean production techniques in different stages of the red meat value chain and reports 2- 3% potential cost savings at each stage of the chain.Lean process, red meat industry, Takt-time, work standardization, Livestock Production/Industries,

Utilizing rapid prototyping 3D printer for fabricating flexographic PDMS printing plate

Recently printed electronic field is significantly growth. Printed electronic is to develop electrical devices by printing method. Conventional printing method that has been studied for this kind of printed electronic such as flexographic, micro contact printing, screen printing, gravure and ink jet. In flexographic and microcontact printing, a printing plate is used to transfer the designed and desired pattern to substrate through conformed contact. Therefore printing plate is play a big role in this area. Printing plate making by photopolymer which used in flexographic have limitation in achieving a micro-scale of pattern size. However, printing plate of microcontact printing have an advantages in producing micro, even nano-scale size by PDMS (Polydimethylsiloxane). Hence, rapid prototyping 3D printer was used for developing a PDMS micro-scale printing plate which will be used in reel to reel (R2R) flexographic due to high speed, low cost, mass production of this type of printing process. The flexibility of 3D printer in producing any shape of pattern easily, contributed the success of this study. A nickel plating and glass etching master pattern was used in this study too as master pattern mould since 3D printer has been reached the micro size limitation. The finest multiple solid line array with 1mm width and 2mm gap pattern of printing plate was successfully fabricated by 3D printer master mould due to size limitation of the FDM (Fused Deposition Modeling) 3D printer nozzle itself. However, the micro-scale multiple solid line array of 100micron and 25micron successfully made by nikel platting and glass etching master mould respectively. Those types of printing plate producing method is valueable since it is easy, fast and low cost, used for micro-flexographic in printed electronic field or biomedical application

Governance strategies in sustainable campus using Rasch model

In moving towards sustainability, university needs to establish a good governance strategy which practices to transform a positive sustainable culture toward successful green campus. Howe ver, due to constraint of knowledge and commitment regarding sustainability integration has caused weakness in the implementation of green concept in majority of Malaysian universities. This paper is presents one of the five dimensions of a developed hypot hetical integrated sustainable campus model which is university governance. The university governance dimension consists of 5 constructs and 23 items which are strategies for the university to be complied. These strategies were uncovered using questionnair e survey with 35 selected experts who are currently active in sustainable campus activities and researches. Collected data from this survey was analysed using Rasch method in Winstep software to measure items reliability, separation index, items polarity, item fit and item person map. Results from the analysis indicated that 19 strategies were significant to be implemented. Thus, it provides good information for universities to adopt these sustainable campus strategies in making their campus as a role mode l for a sustainable and conducive living environment

The relevance of outsourcing and leagile strategies in performance optimization of an integrated process planning and scheduling

Over the past few years growing global competition has forced the manufacturing industries to upgrade their old production strategies with the modern day approaches. As a result, recent interest has been developed towards finding an appropriate policy that could enable them to compete with others, and facilitate them to emerge as a market winner. Keeping in mind the abovementioned facts, in this paper the authors have proposed an integrated process planning and scheduling model inheriting the salient features of outsourcing, and leagile principles to compete in the existing market scenario. The paper also proposes a model based on leagile principles, where the integrated planning management has been practiced. In the present work a scheduling problem has been considered and overall minimization of makespan has been aimed. The paper shows the relevance of both the strategies in performance enhancement of the industries, in terms of their reduced makespan. The authors have also proposed a new hybrid Enhanced Swift Converging Simulated Annealing (ESCSA) algorithm, to solve the complex real-time scheduling problems. The proposed algorithm inherits the prominent features of the Genetic Algorithm (GA), Simulated Annealing (SA), and the Fuzzy Logic Controller (FLC). The ESCSA algorithm reduces the makespan significantly in less computational time and number of iterations. The efficacy of the proposed algorithm has been shown by comparing the results with GA, SA, Tabu, and hybrid Tabu-SA optimization methods

Mass Customization Strategies And Their Relationship To Lean Production In The Homebuilding Industry

Current housing trends point to an increasing interest from homebuyers to demand houses that reflect their personal and unique styles, and which are individually configured according to these needs (NAHB, 2004). These homebuyers in turn are unwilling to settle for standard models that sacrifice what they really want in a home. At the same time this creates pressure on builders who are reluctant to sacrifice production efficiencies by deviating from standard models. Such customization desired by demanding customers can disrupt the entire estimating, production, delivery and management process, making it even more difficult to manage homebuilding efficiently and effectively. The question faced by homebuilders in this conditions is, how to manage this trade-off and deliver exactly what homebuyers want, at reasonable prices and lead times with minimal disruptions in efficiencies. Mass Customization (MC) is an emerging production paradigm that seeks to manage the trade-offs between product variety and mass efficiency, while fulfilling individual customer requirements. The general purpose of this research is to improve the effectiveness and efficiency of housing production through the implementation of mass customization strategies. More specifically, this research focuses on the study of the production system through the application of lean production principles, as an approach to enable mass customization. This study first characterizes how much product choice is currently being offered by U.S. homebuilders and what is the impact of customization on production efficiency; and then focuses on the evaluation of the relationships between mass customization and lean production principles. Results revealed that homebuilders offering increased product choice are likely to suffer poorer labor productivity, greater inventory, higher production costs, more quality issues, less satisfied homebuyers, and lower space efficiency. In general, operational performance deteriorated with an increase in product choice. Therefore, industrialized housing manufacturers have not reached the ideal of mass customization and are paying a price for offering more choices to their customers. Homebuilders could mitigate these challenges by using lean concepts. In general, case studies showed that product choice does not necessarily make the implementation of lean concepts more difficult. Some lean concepts, like workload balancing and standardizing tasks, clearly facilitated the handling of product choice. Other lean concepts, like creating a continuous process flow, can be made to work well, even with increased choice. Case study results suggested that good concepts for lean (e.g., efficient continuous flow, effective pull system, workload leveling, defect-free processes, standard tasks, good visual controls, and reliable technology) were also good concepts for (or easily accommodated) handling a range of product choice

Factors shaping the evolution of electronic documentation systems

The main goal is to prepare the space station technical and managerial structure for likely changes in the creation, capture, transfer, and utilization of knowledge. By anticipating advances, the design of Space Station Project (SSP) information systems can be tailored to facilitate a progression of increasingly sophisticated strategies as the space station evolves. Future generations of advanced information systems will use increases in power to deliver environmentally meaningful, contextually targeted, interconnected data (knowledge). The concept of a Knowledge Base Management System is emerging when the problem is focused on how information systems can perform such a conversion of raw data. Such a system would include traditional management functions for large space databases. Added artificial intelligence features might encompass co-existing knowledge representation schemes; effective control structures for deductive, plausible, and inductive reasoning; means for knowledge acquisition, refinement, and validation; explanation facilities; and dynamic human intervention. The major areas covered include: alternative knowledge representation approaches; advanced user interface capabilities; computer-supported cooperative work; the evolution of information system hardware; standardization, compatibility, and connectivity; and organizational impacts of information intensive environments
