ABSTRAK

Projek ini adalah mengenai penyelidikan tentang pelaksanaan Teknologi Kumpulan dalam industri pembuatan tempatan. Teknologi Kumpulan (GT) adalah satu falsafah yang mengambil kira persamaan di antara masalah-masalah dan menerusi penggabungan masalah-masalah tersebut, satu jalan penyelesaian dapat diperoleh yang seterusnya akan menjimatkan masa dan tenaga. Konsep GT menekankan kepada pengurangan dimensi sesuatu situasi yang ingin dikawal. Kilang akan dibahagikan kepada sel-sel yang lebih kecil serba lengkap dengan mesin dan peralatan yang diperlukan untuk penghasilan sesuatu kumpulan bahagian. Demi mencapai objectif projek, survei pos telah dihantar kepada 48 syarikat dan hanya 8 yang membalas survei tersebut. Satu syarikat telah dipilih sebagai kajian untuk penyelidikan ini. Syarikat tersebut terletak di kawasan perindustrian Demak Laut dan terlibat dalam industri pemprosesan makanan. Temu ramah telah dijalankan semasa lawatan ke kilang tersebut untuk mengenalpasti kebarangkalian untuk melaksanakan GT dalam erti kata proses pembuatan dan susun atur kilang di kilang tersebut. Susun atur baru kilang tersebut telah direka berdasarkan maklumat semasa lawatan dan temu ramah dibuat. Objektif penyelidikan dan kertas cadangan ini telah dicapai. Saranan untuk kajian selanjutnya adalah untuk meluaskan skop kajian akibat daripada kekurangan syarikat yang sesuai di Kuching. Pengumpulan maklumat juga harus dilakukan dengan menelefon syarikat untuk mempercepatkan proses membalas survei. Adalah disarankan juga hanya syarikat tempatan patut dipilih untuk kajian.

ABSTRACT

The project is about the study on the implementation of Group Technology in the local manufacturing industry. Group Technology (GT) is a manufacturing philosophy that states if many problems are similar and that, by grouping similar problems, a single solution can be found to a set of problems, thus saving time and effort. GT concept emphasizes in reducing the dimension of the situation to be controlled. Instead of being functionally laid out, the factory is divided into smaller cells in such a way that each cell is equipped with all the machines and equipment needed to complete a particular family of components. In achieving the project objectives, mail survey was sent to 48 samples.

Out of the 48 companies only 8 replied. Only one company was chosen as the case study for this research. The company involves in food processing and is located in Demak Laut Industrial Park. Observation and interview was done during the visit to the company to identify the possibility of implementing and integrating GT concept in terms of manufacturing processes and plant layout. A new plant layout was designed to be proposed to the company based on the observation done during the factory visit and interview. Objectives of the research and the proposal are achieved. Recommendations for the research are to expand the scope of the project to a wider area due to the insufficient sampling group which is suitable in Kuching. Information gathering should include follow-up calls being made to the sampling groups to speed up the reply process.

It is also advised to choose local companies as the sampling group.

CHAPTER 1

INTRODUCTION

1.0 Introduction

Group Technology (GT) is a manufacturing philosophy that states if many problems are similar and that, by grouping similar problems, a single solution can be found to a set of problems, thus saving time and effort. The objectives of GT are best achieved in business concerned with small to medium batch production which represents a major part of manufacturing industry. The traditional approach to this type of manufacture is to make use of a functional layout in the factory where similar machines are grouped according to type [1].

As a result of this form of machine layout, where only machining operations of a particular type may be performed in a limited area of the workshop, the workpiece itself must travel a considerable distance around the workshop before all the operations are performed upon it. This usually leads to a long throughput time, thus, the planning of process route becomes an extremely difficult task since a number of similar machine tools may be considered at each point in the sequence of manufacturing operations.

(18)

As a result, a different concept of manufacturing organization and layout has been developed to overcome the difficulties. The GT concept emphasise in reducing the dimension of the situation to be controlled. Instead of being functionally laid out, the factory is divided into smaller cells in such a way that each cell is equipped with all the machines and equipment needed to complete a particular family of components. It has been found that by switching to this type of cellular manufacture, many benefits of flowline production can be attained in a batch production system [1].

1.1 Project Objectives

There are two main objectives for this project and they are as follows.

i. To study the potential of group technology in local manufacturing industry.

ii. To propose a system consists of group technology to the chosen company.

1.2 Scopes of the project

Malaysia has established a diverse and quickly-growing manufacturing sector that plays an increasing role in the Malaysian economy. Malaysia built up its manufacturing sector mainly in the 1970s and 1980s, utilizing its long-established industrial centers on the island of Penang and the Klang Valley, its well-developed transportation infrastructure (including seaports and railways), and the entrepreneurial skills of its

(19)

Group Technology Introduction

small and medium-sized businesses. The industrial sector initially consisted of oil refining, machinery assembly, and light industries (including foodstuff processing and textile manufacturing) [2].

Malaysian manufacturing sector was boosted by the extensive growth of the electric assembly and electronics sectors. Malaysia became an important producer of radios, television sets, stereo equipment, and other related products. There was further growth in the manufacturing sector, especially in export-oriented electronics production, including semiconductors, silicon wafers, and other items. Malaysia has become the world's third- largest producer, and one of the world's largest exporters, of semiconductors [2].

The manufacturing division includes establishments engaged in the mechanical or chemical transformation of materials or substances into new products. These establishments are usually described as plants, factories, or mills and characteristically use power driven machines and materials handling equipment. Establishments engaged in assembling component parts of manufactured products are also considered manufacturing if the new product is neither a structure nor other fixed improvement [2].

This project will cover the extent of implementation of GT in the local manufacturing industry particularly in Kuching, Sarawak. Before that, in-depth research and study on the topic would be done to gain knowledge, understanding the principles and fundamentals of GT. The information collected would be used later to come up with proposal of implementation to the selected company.

In the first chapter, an introduction to the topic was done. This section explained briefly on what the project is all about. The objectives of the project were also defined as well as the scope of the project. There is also an overview of every chapters included.

The second chapter is literature review. This chapter will cover the history of GT and its development. Besides that, it would also include other components of GT such as the fundamentals of GT, part families, application of GT and analysis in GT.

The third chapter is methodology. This chapter will describe on the strategy used to do this research and to give the reader an overall understanding of all steps involved in carrying out this project. It will cover objectives of survey and sampling group, information gathering, analysis of survey data and expected problem during project.

The fourth chapter is where the results, analysis and discussion will be presented.

Data obtained from the questionnaires and interview will be analyzed and one company will be chosen to be the case study for this research.

In the fifth chapter, proposal of GT implementation will be discussed. This proposal will include the analysis and suggestions of the recommended new layout.

Chapter six would be the conclusion, including with the limitations and recommendations of the research.

CHAPTER 2

LITERATURE REVIEW

2.0 Introduction

In general, group technology (GT) is considered as a manufacturing philosophy which identifies and exploits the similarity of parts and operation processes in the design and the manufacture of products. GT is vital in the foundation for successful development and implementation of computer-integrated manufacturing through the application of the part family and its analysis.

2.1 History of Group Technology

The initial idea on GT first surfaced in 1925 where R. Flanders from the United States presented a paper on organizing manufacturing at Jones and Lamson Machine Company. In 1937, A. P. Sokolovski from the USSR suggested that parts of similar configurations and features where all factors being equal should be manufactured in the same way by a standardized technological and manufacturing process. S.P. Mitrofanov, also from the USSR then expanded this theory and introduced GT. Mitrofanov stated

(22)

that design simplification and standardization are the necessity to an effective GT program. In 1937, a U.S.A. manufacturer announced a technique in their manufacturing system, which was the same year Sokolovski published his paper. In 1949, a Swede named A. Korling presented on “group production” which is an adaptation of production line techniques to batch manufacturing. In his presentation he described that work was divided in groups where each contained machine and tooling of certain purposes [3,4].

In 1963, GT was applied at Hopkinsons Ltd., in Huddersfield, England which was similar to the one implemented at Forges et Ateliers several years earlier. GT was also implemented at a machine tool manufacturing plant in Sringfield, Vermont in 1963.

Mitrofanov’s work was published in Russia and German in 1966. First International Conference on Classification and Coding was held in Fort Lauderdale, Florida, United States also in the year 1966. In 1967, the Second Conference on Classification, Coding and Group Technology was held at Waldorf-Astoria Hotel in New York. In 1968, the Third International Conference on Classification, Coding and Group Technology was held in Fort Lauderdale, Florida [3,4].

In 1969, there was a conference organized by the International Labor Organization at Turin, Italy, where the main topic being discussed at the conference was on the meaning of GT. Also during the same year, Langston Division of Harris-Intertype of New Jersey, United States applied GT where they transform a traditionally arranged machine shop into “family of part” lines. The implementation has improved the productivity by 50% and at the same time has reduced leadtimes to days rather than weeks [3,4].

Group Technology Literature Review

7 2.2 Fundamentals of Group Technology

Grouping objects (i.e., components, parts, or systems) into families based on the object features has been done using GT approaches. Similar components can be grouped into design families, and modifying an existing component design from the same family would lead to new designs. The philosophy of group technology is an important concept in the design of advanced integrated manufacturing systems. GT classifies and codes parts by assigning them to different part families based on their similarities in shape and/or processing sequence [4].

Figure 2.1 below shows an example of three different components having similar geometrical properties. All three parts are manufactured by using the same machine. The main difference between each component is the machining process. All three components are made from the same raw material which is a cylinder shaped rod.

Group technology is an example of optimizing the strategic perspective on machine technology so that when the tactical aspects of the technology are considered, the results could be for the better of the company. The similarities between processes, products and materials can be used as the basis of grouping and as the basis of subsequent cellular manufacturing [5]. Group technology can and has been successfully applied in manufacturing, in production planning and control, in purchasing and in sales as well as in process design, parts decisions and elsewhere in organizations [5].

Figure 2.2 below shows another example of different but similar in characteristics components. All three cubicle parts looked different but are manufactured of the same equipment which is the multi-axis machining center. The machine could orient the component in various axis to execute different types of operation depending on the instructions being input into it.
