1.4 Objectives
Objectives of this project are to: i.
To investigate the problems and wastes in the assembly process of table top fan. ii.
To simulate the processes for higher productivity and efficiency in table top fan assembly processes.
iii. To enhance work quality.
1.5 Scopes of Project
This project will focus on the productivity improvement of table top fan assembly processes. To ensure the objective is achieved, some of the important elements must be
considered. These are: ii.
Studying the assembly processes and present time study for table top fan assembly.
iii. Using Arena simulation software to simulate the assembly processes.

1.7 Summary
This project is about the work study assessment for productivity improvement of table top fan assembly process using Arena simulation. This chapter introduced the project
background and the objective of the project. In addition, the problem statements and expected results also being clarified in order to come out with the improvement plan
later. The following chapter consists of the literature review and knowledge that required in conducting the whole study.

CHAPTER 2
LITERATURE REVIEW
2.1 Introduction
This chapter describes about the works that had been done on this topic. It is includes the literature review regarding productivity improvement and techniques. The simulation
tools especially Arena is also includes in this chapter.
2.2 Productivity Improvement
Poor job match, poor work ethic, absenteeism, substance abuse, employee fraud and theft, weak managers, and employee turnover are some of the factors that contribute to
substandard productivity. Today’s global business leaders depend on significant productivity increases to maximize the bottom line. Consequently, employees are asked
to do more each day with less, resulting in a mismatch of resources and loss of productivity. Productivity is being better today than yesterday, and that tomorrow will
be better than today. The concept of what is better and how to become better is changing.
Productivity in its broadest sense is the quantitative relationship between product that have been produced and the resources which been used. There is clear a distinct
difference between production and productivity. It is quite possible to increase the actual volume of production and yet decrease productivity. Productivity is an overall
conception which is difficult to express or to measure. It is, however, possible to consider productivity in terms of various basic resources used in industry. It is
7 sometimes expressed in term of output from labor, or from services, or from the capital
invested.
Whereas traditionally, productivity is viewed mainly as an efficiency concept which is amount of outputs in relation to efforts or resources used, productivity is now viewed
increasingly as an efficiency and effectiveness concept, effectiveness being how the company meets the dynamic needs and expectations of customers. Productivity is now
seen to depend on the value of the products and services utility, uniqueness, quality, convenience, availability, etc and the efficiency with which they are produced and
delivered to the customers.
Knodd, 1994 has identified some common, noncost ways of evaluating the productivity of various resources. Terms like
efficiency
,
busyness
and
idleness
, and
utilization
can be used loosely; they also have precise meanings and can be measured numerically.
Examples follow, first for equipment and other nonhuman resources, then for people.
