Lean production system definition from the perspective of Malaysian industry
“Muda” is a term in the Toyota Production System (TPS), which refers to waste that occurs in the manufacturing process. Waste is removed from the production process by eliminating activity that does not add value to the customer through a continuous improvement activities. This is the basis concept for TPS in order to produce products that meet customers’s demand and requirements which then indirectly reduce the cost of production. Lean production concept has been implemented in various types of organizations. However, a low success rate for the implementation of lean production has become the attention of practitioners and researchers in the industry. Among the issues that contribute to this situation are confusion about the definition of lean and lack of knowledge on how to implement lean, which caused misunderstanding. In addition, there are no strategic planning and lack of support from the top management. Thus, the objective of this study is to develop a definition of lean from Malaysian context. The study is expected to help organizations implementing lean concepts with success and thus increasing the organizational competitiveness
A Conceptual Model of Lean Manufacturing Dimensions
AbstractLean manufacturing or also known as lean production has been one of the most popular paradigms in waste elimination in the manufacturing and service industry. Thus, many firms have grabbed the benefits to practice lean manufacturing in order to enhance quality and productivity. However, previous research shows that there are various sets of tools or techniques that had been adopted at a certain degree across firms according to their own understanding of lean manufacturing. The scenario resulted with varying leanness measures in order to measure lean practices. This paper describes a preliminary study in developing a conceptual model to measure leanness in manufacturing industry. Thorough literature survey, books and report analysis contribute to the main preliminary analysis of this study. The most common tools or techniques and their usefulness have been investigated. In this research, a conceptual model for leanness measurement in the manufacturing industry has been developed and designed in two main levels, namely the dimensions and the factors. There are seven main dimensions in measuring leanness in lean manufacturing practices such as manufacturing process and equipment, manufacturing planning and scheduling, visual information system, Supplier relationship, customer relationship, workforce and product development & technology. In addition, the model also shows how lean dimensions in the manufacturing system relate to eight types of wastes
Kedudukan dinamik berasaskan pembaikan halaju bagi mengoptimum komputasi perlanggaran dalam simulasi kain
Kajian ini bertujuan membangun Teknik Kedudukan Dinamik Berasaskan Pembaikan Halaju (VcCPBD) bagi mempertingkat kestabilan tindak balas perlanggaran melibatkan kedudukan, halaju dan pecutan nod partikel selepas berlaku perlanggaran Sesama Sendiri (SCD). Uji kaji menunjukkan perlanggaran teknik VcCPBD yang direkod adalah tidak melebihi 5 mili saat pada setiap langkah masa. Selain daripada itu, purata perlanggaran teknik ini juga mencapai nilai lebih kecil sebanyak 1.018% berbanding dengan teknik Halaju Gerakan 1.995% dan teknik Berasaskan Kedudukan Dinamik (PBD) 1.151%. Uji kaji turut menunjukkan teknik yang dicadang dapat menjana peningkatan masa komputasi perlanggaran yang signifikan berbanding dengan pendekatan tradisional
The Benefits of Enterprise Resource Planning (ERP) System Implementation in Dry Food Packaging Industry
AbstractThe corporate competitive environment is being liberalized and globalized, therefore the organizations, especially dry food packaging industry, need greater interaction between their stakeholders. One of the problems organizations face to is the segregation of the business functions in an organization. Thus, the business experienced to implement ERP systems for solving this problem. In contrast, the ERP projects have not been effective enough and hence have been unable to achieve all the results envisaged. Therefore, an in depth understanding about the benefits of ERP implementation is needed to ensure the successful system implementation. This study seeks to determine and classify the benefits of ERP system implementation in dry food packaging industry. The methodology of this research comprised of three phases: define the benefits of ERP system implementation from the current literatures, categorize them into strategic, tactical and operational benefits in each business functions in an organization. These ERP benefits are summarized in this paper as a research finding to assist the managers in implementing ERP system successfully
Computed tomography image reconstruction in 3D voxelspace
The aim of the study was to investigate the relationship between 2D gray scale pixels and 3D gray scale pixels of image reconstructions in computed tomography (CT). The 3D space image reconstruction
from data projection was a challenging and difficult research problem. The image was normally reconstructed from the 2D data from CT data projection. In this descriptive study, a synthetics 3D Shepp-Logan phantom was used to simulate the actual data projection from a CT scanner. Real-time data projection of a human abdomen was also included in this study. Additionally, the Graphical User Interface (GUI) for the application was designed using Matlab Graphical User Interface Development Environment (GUIDE). The application was able to reconstruct 2D and 3D images in their respective spaces successfully.The image reconstruction for CT in 3D space was analyzedalong with 2D space in order to show their relationships and shared properties for the purpose of constructing these images
An Automated Size Recognition Technique for Acetabular Implant in Total Hip Replacement
Preoperative templating in Total Hip Replacement (THR) is a method to
estimate the optimal size and position of the implant. Today, observational
(manual) size recognition techniques are still used to find a suitable implant
for the patient. Therefore, a digital and automated technique should be
developed so that the implant size recognition process can be effectively
implemented. For this purpose, we have introduced the new technique for
acetabular implant size recognition in THR preoperative planning based on the
diameter of acetabulum size. This technique enables the surgeon to recognise a
digital acetabular implant size automatically. Ten randomly selected X-rays of
unidentified patients were used to test the accuracy and utility of an
automated implant size recognition technique. Based on the testing result, the
new technique yielded very close results to those obtained by the observational
method in nine studies (90%)
Kebolehcapaian nasihat bagi pengurusan penyakit tanaman oleh pekebun kecil lada hitam, Sarawak: Tinjauan awal
Lada hitam (Piper nigrum L.) merupakan salah satu tanaman industri yang mempunyai nilai eksport yang tinggi dan
menyumbang kepada pertumbuhan ekonomi di Malaysia khususnya di Sarawak. Kebelakangan ini insiden serangan
penyakit terhadap tanaman lada hitam telah merencat pengeluaran produktiviti tanaman ini. Situasi semasa yang
dihadapi oleh pekebun kecil yang mampu memberi impak terhadap kualiti dan kuantiti hasil tanaman mereka jarang
dilaporkan. Kaedah penasihatan yang kurang efisien, ketidakcukupan pengetahuan dan tempoh masa yang panjang
bagi capaian sesuatu nasihat dipercayai boleh memberi kesan kepada aspek ekonomi dan pengurusan penyakit.
Oleh itu, satu tinjauan awal telah dilaksanakan untuk mengenalpasti situasi semasa yang merangkumi aspek
penasihatan dan penyakit tanaman khususnya bagi tanaman lada hitam daripada perspektif pekebun kecil di kawasan
luar bandar. Kaedah penyelidikan ini menggunakan borang senarai semak dan telah diedar kepada pekebun kecil
yang mengusaha tanaman lada hitam di kawasan Penempatan Semula Asap Koyan, Belaga yang terletak di
Bahagian Kapit, Sarawak. Hasil tinjauan awal ini mendapati pekebun kecil yang mengusaha tanaman lada hitam
sering menghadapi masalah tanaman berpenyakit dan turut menghadapi isu kaedah penasihatan yang kurang efisien.
Kaedah sistem penasihatan baru yang strategik seperti penggunaan teknologi maklumat perlu diperkenalkan supaya
pekebun kecil di kawasan luar bandar boleh memperolehi maklumat dengan pantas bagi menyelesaikan masalah
apabila menghadapi insiden serangan penyakit tanaman dan membantu mengurangkan risiko kerugian akibat
kemusnahan tanaman
